By the way, when the ultrasonic diagnostic apparatus is not used or when the ultrasonic diagnostic apparatus is moved, it is conceivable that the user manually operates the power button to turn off the power of the ultrasonic diagnostic apparatus. However, since the user needs to operate the power button, it takes time and effort on the part of the user. For example, if the user has to manually operate the power button to turn off the power each time the ultrasonic diagnostic apparatus is moved, the user will have to work hard every time the ultrasonic diagnostic apparatus is moved.

On the other hand, when moving the ultrasonic diagnostic apparatus, it is conceivable to move the ultrasonic diagnostic apparatus with the power turned on without turning off the power. However, since the power is on, power is consumed even though the ultrasound diagnostic device is not in use.

An object of the present invention is to switch the power mode of an ultrasonic diagnostic apparatus to a mode with lower power consumption without the user manually operating the power supply when moving the ultrasonic diagnostic apparatus.

One aspect of the present invention is to provide an ultrasonic diagnostic apparatus that generates ultrasound images by transmitting and receiving ultrasonic waves, including a determination unit that determines whether or not the apparatus is moving based on the usage status of the apparatus. , power control means for switching the power mode of the self-device from a drive mode to a power-saving mode that consumes less power than the drive mode when the determination means determines that the self-device is moving; This is a characteristic ultrasonic diagnostic device.

According to the above configuration, when moving the ultrasonic diagnostic apparatus, the power mode of the ultrasonic diagnostic apparatus is switched from the drive mode to the power saving mode. If the ultrasound diagnostic device is being moved or is about to be moved, it is presumed that the ultrasound diagnostic device is not being used. Therefore, by switching the power mode from drive mode to power saving mode, the power consumption of the ultrasound diagnostic equipment can be reduced compared to keeping the power mode in drive mode even when the ultrasound diagnostic equipment is not in use. can be reduced.

The determining means may determine that the ultrasound diagnostic device is not in use based on the determination result that the ultrasound diagnostic device is moving. The determining means may determine whether or not the ultrasound diagnostic device is being used, and based on the determination result, determine that the ultrasound diagnostic device is being moved or is about to be moved. In other words, there is a correlation between the use of the ultrasound diagnostic device and the movement of the ultrasound diagnostic device. By determining whether the ultrasound diagnostic device is being used, it may be inferred whether the ultrasound diagnostic device is moving, or conversely, whether the ultrasound diagnostic device is moving or not. By determining whether or not the ultrasound diagnostic device is being used, it may be inferred whether or not the ultrasound diagnostic device is being used.

When the power mode is the drive mode, the power of the ultrasonic diagnostic apparatus is turned on, power is supplied from the power source to each part of the ultrasonic diagnostic apparatus, and imaging using ultrasound is possible.

The power saving mode includes one or more modes. For example, power saving modes include power off mode, standby mode, or hibernation mode. The power off mode is a mode in which the ultrasound diagnostic apparatus is powered off. In this case, power is not supplied from the power supply to each part of the ultrasonic diagnostic apparatus. The standby mode and the hibernation mode are modes in which power is supplied from the power supply to a part of the ultrasound diagnostic apparatus. The hibernation mode is a mode that consumes less power than the standby mode. These modes are just examples; another mode may be defined, or the mode may be set by the user.

The power control means may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. The power control means may switch the power mode in stages from a mode with high power consumption to a mode with low power consumption. For example, the power control means may switch the power modes in the order of standby mode, hibernation mode, and power off mode.

The ultrasonic diagnostic device may further include a handle used when moving the device. The determining means may determine that the device is moving when the handle is being held by the user.

If the handle is being held by the user, it is presumed that the ultrasound diagnostic apparatus is being moved or is about to be moved. In other words, it is assumed that the ultrasound diagnostic device is not being used. Therefore, the power mode is switched from drive mode to power saving mode.

The ultrasound diagnostic apparatus may further include an operation panel operated by a user, and a display disposed toward the operation panel and displaying an ultrasound image. The handle may be installed on the back side of the display.

If the handle installed on the back side of the display is grasped, it is strongly assumed that the ultrasonic diagnostic apparatus is being moved or is about to be moved. Therefore, the power mode is switched from drive mode to power saving mode.

The display may have a foldable configuration. The determining means may determine that the device is moving when the handle is being held by the user while the display is folded.

If the display is folded, it is assumed that the ultrasound diagnostic device is not in use. Furthermore, if the display is folded and the handle is gripped by the user, it is strongly assumed that the ultrasound diagnostic apparatus is being moved or is about to be moved. Therefore, the power mode is switched from drive mode to power saving mode.

The ultrasonic diagnostic apparatus may further include a human sensor. The determination means determines whether the own device detects a person when no person is detected by the human sensor, the operation panel is not operated, the display is folded, and the handle is gripped by the user. may be determined to be moving.

The ultrasonic diagnostic apparatus may further include a sensor that detects the inclination of the ultrasonic diagnostic apparatus. The determining means may determine that the device is moving when the tilt detected by the sensor is greater than or equal to a threshold value.

For example, if the tilt (angle) of a portable ultrasound diagnostic device is detected and the tilt is equal to or greater than a threshold value, it is assumed that the ultrasound diagnostic device is being carried and moved by the user. Therefore, the power mode is switched from drive mode to power saving mode.

According to the present invention, when moving the ultrasound diagnostic device, the power mode of the ultrasound diagnostic device can be switched to a mode with lower power consumption without the user manually operating the power supply.

Further, the display 16 can be rotated to the front side or the back side of the ultrasonic diagnostic apparatus 10 about the shaft 24 as a rotation axis. For example, the rotation is realized by a hinge mechanism or the like. In the example shown in FIG. 3, the display 16 is rotated toward the back side of the ultrasonic diagnostic apparatus 10 about the axis 24, and this state is a state in which the display 16 stands up. In the example shown in FIG. 4, the display 16 is rotated toward the front side of the ultrasonic diagnostic apparatus 10 using the shaft 24 as the rotation axis (see arrow A), and this state is the state in which the display 16 is folded. .

The probe 36 is a device that transmits and receives ultrasonic waves. The probe 36 is not particularly limited, and may be, for example, a 1D array transducer (that is, a transducer made up of a plurality of ultrasonic transducers arranged one-dimensionally), or a 2D array transducer ( In other words, it includes a transducer formed by two-dimensionally arranging a plurality of ultrasonic transducers. As an ultrasonic scanning method using the probe 36, sector scanning, linear scanning, convex scanning, etc. are used.

The transmitting/receiving section 38 functions as a transmitting beamformer and a receiving beamformer. When transmitting ultrasonic waves, the transmitting/receiving unit 38 supplies a plurality of transmission signals having a certain delay relationship to the plurality of ultrasonic transducers included in the probe 36. As a result, an ultrasonic transmission beam is formed. When receiving ultrasonic waves, reflected waves (RF signals) from within the living body are received by the probe 36, and a plurality of received signals are output from the probe 36 to the transmitter/receiver 38. The transmitting/receiving unit 38 forms a receiving beam by applying phasing and addition processing to a plurality of received signals. The beam data is output to the signal processing section 40. That is, the transmitting/receiving unit 38 performs delay processing on the received signals obtained from each ultrasonic transducer according to the delay processing conditions for each ultrasonic transducer, and processes the plurality of received signals obtained from the plurality of ultrasonic transducers. A reception beam is formed by addition processing. The delay processing conditions are defined by reception delay data indicating delay time. A reception delay data set (that is, a set of delay times) corresponding to a plurality of ultrasonic transducers is supplied from the control device 52.

Due to the action of the transceiver section 38, the ultrasound beam (that is, the transmit beam and the receive beam) is electronically scanned, thereby forming a scanning plane. The scanning plane corresponds to a plurality of pieces of beam data, which constitute received frame data (specifically, RF signal frame data). Note that each beam data is composed of a plurality of echo data arranged in the depth direction. By repeating the electronic scanning of the ultrasonic beam, a plurality of received frame data aligned on the time axis are output from the transmitter/receiver 38. These constitute a received frame sequence.

When the ultrasound beam is two-dimensionally electronically scanned by the action of the transmitting/receiving unit 38, a three-dimensional echo data acquisition space is formed, and volume data as an echo data collection is acquired from the three-dimensional echo data acquisition space. be done. By repeating the electronic scanning of the ultrasonic beam, a plurality of volume data aligned on the time axis is output from the transmitter/receiver 38. They constitute a volume data string.

The signal processing section 40 is a device that applies signal processing such as detection, logarithmic compression, and coordinate transformation to the beam data output from the transmitting/receiving section 38. The beam data after signal processing is output to the image generation section 42. The beam data after signal processing may be stored in the storage device 48.

The image generation section 42 is a device (for example, a DSC (digital scan converter)) having a coordinate conversion function, an interpolation processing function, etc., and generates an ultrasound image (for example, B mode) based on the beam data output from the signal processing section 40. generate a tomographic image). The ultrasound images may be stored in storage device 48. For example, an ultrasound image is displayed on display 16.

The UI 44 is a user interface and includes a display (for example, the displays 16 and 20) and an input device (for example, the operation panel 14). The display may also be a device that also serves as an input device. For example, a GUI (Graphic User Interface) may be realized by a display. Further, a user interface such as a touch panel may be realized by a display.

Sensor 46 includes various sensors. For example, the sensor 46 includes at least one of a human sensor, a pressure sensor, an acceleration sensor, and a magnetic sensor. The detection results of the sensor 46 are output to the control device 52.

For example, as shown in FIGS. 1 and 3, a human sensor 46a is installed above the display 16 toward the front side of the ultrasound diagnostic apparatus 10. As a result, a person in front of the display 16 is detected by the human sensor 46a. For example, a known human sensor is used as the human sensor 46a. Note that the human sensor 46a may be installed on the display 20 or the operation panel 14.

The pressure sensor is installed on the back handle 30 and detects the gripping force when the back handle 30 is gripped by the user. For example, the pressure sensors include a right pressure sensor and a left pressure sensor. The right pressure sensor is installed on the right handle 30R. When the right handle 30R is gripped by the user, the right pressure sensor detects the gripping force. The left pressure sensor is installed on the left handle 30L. When the left handle 30L is gripped by the user, the left pressure sensor detects the gripping force. For example, a known pressure sensor is used as the pressure sensor.

The acceleration sensor is installed on the main body 12 or the casters 34 and detects acceleration. Movement of the ultrasound diagnostic apparatus 10 is detected by the acceleration sensor. For example, a known acceleration sensor is used as the acceleration sensor.

The magnetic sensor is installed at the bottom of the display 16, on or around the axis 24. As shown in FIG. 4, when the display 16 is rotated to the front side of the ultrasound diagnostic apparatus 10 and folded, the magnetic sensor detects the folding. As the magnetic sensor, for example, a known magnetic sensor is used.

In addition, a switch that is pushed in when the display 16 is folded (hereinafter referred to as a "detection switch") is installed at the bottom of the display 16, on or around the shaft 24, and when the detection switch is pressed, the display 16 is Folding may be detected. For example, a known switch is used as the detection switch.

The folding of the display 16 may be detected using both the magnetic sensor and the detection switch, or either the magnetic sensor or the detection switch may be installed in the ultrasonic diagnostic apparatus 10 to detect the folding of the display 16. You can.

The storage device 48 is a device that constitutes one or more storage areas for storing data. The storage device 48 is, for example, a hard disk drive (HDD), a solid state drive (SSD), various types of memory (for example, RAM, DRAM, ROM, etc.), other storage devices (for example, an optical disk, etc.), or a combination thereof. . For example, ultrasound images and the like are stored in the storage device 48.

The power supply 50 is constituted by a power supply circuit, and supplies power to each part of the ultrasonic diagnostic apparatus 10. The power supply circuit is an AC (Alternate Current)/DC (Direct Current) conversion circuit. Power source 50 may include a battery.

The control device 52 controls the operation of each part of the ultrasound diagnostic apparatus 10. For example, the control device 52 includes a determination section 54 and a power control section 56, and controls the power mode of the ultrasound diagnostic apparatus 10.

The determination unit 54 determines whether the ultrasound diagnostic apparatus 10 is moving based on the usage status of the ultrasound diagnostic apparatus 10. Specifically, the determination unit 54 determines whether the ultrasound diagnostic apparatus 10 is moving based on the detection result by the sensor 46. The determination unit 54 may determine whether the ultrasonic diagnostic apparatus 10 is being used based on the detection result by the sensor 46. The determination unit 54 determines whether the ultrasound diagnostic apparatus 10 is moving or not, based on the determination result of whether the ultrasound diagnostic apparatus 10 is being used. Alternatively, it may be determined whether or not the user is attempting to do so. For example, when the ultrasound diagnostic device 10 is not in use, the determination unit 54 determines that the ultrasound diagnostic device 10 is moving, or determines that the ultrasound diagnostic device 10 is about to be moved. do.

The power control unit 56 controls the power mode of the ultrasound diagnostic apparatus 10 based on the determination result of the determination unit 54. For example, when the determining unit 54 determines that the ultrasound diagnostic apparatus 10 is moving, the power control unit 56 switches the power mode of the ultrasound diagnostic apparatus 10 from the drive mode to the power saving mode. The power saving mode is a power mode that consumes less power than the drive mode.

The drive mode is a mode in which the power source 50 is turned on. When the power mode is the drive mode, power is supplied from the power supply 50 to each part of the ultrasound diagnostic apparatus 10, and imaging using ultrasound is possible.

Power saving modes include, for example, power off mode, standby mode, and hibernation mode.

The power off mode is a mode in which the power supply 50 is turned off. When the power mode is the power off mode, power is not supplied from the power supply 50 to each part of the ultrasound diagnostic apparatus 10. Therefore, no power is consumed.

The standby mode is a mode in which power is supplied from the power supply 50 to only a part of the ultrasound diagnostic apparatus 10. For example, power is supplied from the power supply 50 to a processor (for example, a CPU (Central Processing Unit), etc.), memory, etc. installed in the ultrasound diagnostic apparatus 10. When the power source 50 includes a main power source and a sub power source, power may be supplied from the sub power source to the processor, memory, etc. with the main power source off and the sub power source on.

The sleep mode is a mode in which power is supplied from the power supply 50 to only a part of the ultrasound diagnostic apparatus 10. The hibernation mode is a mode that consumes less power than the standby mode. For example, power is supplied from the power supply 50 to the memory, but not to the processor. When the power source 50 includes a main power source and a sub power source, power may be supplied from the sub power source to the memory and the like while the main power source is off and the sub power source is on.

The types of power saving modes are merely examples, and the power saving mode may include a power off mode and a standby mode or hibernation mode, or only one of the power off mode, standby mode, or hibernation mode may be used as a power saving mode. It may also be set as a power mode. Further, in standby mode and hibernation mode, another power supply destination may be set as the power supply destination.

In the following, as an example, the power saving mode includes a power off mode, a standby mode, and a hibernation mode.

When switching the power mode from the drive mode to the power saving mode, the power control unit 56 may switch the power mode to a preset mode among power off mode, standby mode, and hibernation mode, or may switch the power mode in stages. You can also switch modes.

For example, when switching the power mode from the drive mode to the power saving mode when the power off mode is set as the power saving mode, the power control unit 56 switches the power mode from the drive mode to the power off mode. The same applies when standby mode or hibernation mode is set as power saving mode. The settings may be changed by the user.

As another example, the power control unit 56 switches the power mode from the drive mode to the standby mode, then (for example, after a predetermined time has elapsed), switches the power mode from the standby mode to the hibernation mode, and then switches the power mode from the standby mode to the hibernation mode. The mode may be switched from sleep mode to power off mode.

The control device 52 can be realized using hardware resources such as a processor and an electronic circuit, and devices such as a memory may be used as necessary in its realization. Further, the control device 52 may be realized by, for example, a computer. In other words, all or part of the control device 52 may be realized by cooperation between hardware resources such as a CPU and memory included in the computer and software (program) that defines the operation of the CPU and the like. The program is stored in the storage device 48 or other storage device via a recording medium such as a CD or DVD, or via a communication path such as a network. As another example, the control device 52 may be realized by a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like. Of course, a GPU (Graphics Processing Unit) or the like may be used. The control device 52 may be realized by a single device, or each function of the control device 52 may be realized by one or more devices.

Each embodiment of the operation of the ultrasonic diagnostic apparatus 10 will be described below.

(Example 1: Power control using detection results of human sensor 46a)
In the first embodiment, the power control unit 56 controls the power mode based on the detection result of the human sensor 46a.

The determination unit 54 determines the presence or absence of a user based on the detection result of the human sensor 46a. The determining unit 54 determines that the ultrasonic diagnostic apparatus 10 is in use when the human sensor 46a detects the user, and determines that the ultrasonic diagnostic apparatus 10 is in use when the human sensor 46a does not detect the user. is determined to be unused. If the user is not detected by the human sensor 46a, the determination unit 54 determines that the ultrasound diagnostic apparatus 10 is moving or that the ultrasound diagnostic apparatus 10 is about to be moved. You can.

The determination unit 54 may determine the presence or absence of a user at predetermined intervals. The determining unit 54 determines that the ultrasound diagnostic apparatus 10 is not in use when the length of time during which the human sensor 46a does not detect the user is equal to or greater than the threshold value, and otherwise determines that the ultrasound diagnostic apparatus 10 is not in use. 10 is determined to be used. If the length of time during which the human sensor 46a does not detect the user is equal to or greater than the threshold, the determining unit 54 determines that the ultrasound diagnostic apparatus 10 is moving or that the ultrasound diagnostic apparatus 10 is not moving. It may also be determined that the user is about to be attacked.

When the power mode is the drive mode and the human sensor 46a does not detect a user, the power control unit 56 switches the power mode from the drive mode to the power saving mode. When the length of time during which the human sensor 46a does not detect the user is equal to or greater than a threshold value, the power control unit 56 may switch the power mode from the drive mode to the power saving mode. As described above, the power control unit 56 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. When a user is detected by the human sensor 46a, the power control unit 56 maintains the power mode in the drive mode.

When the power mode is the power saving mode and a user is detected by the human sensor 46a, the power control unit 56 may switch the power mode from the power saving mode to the drive mode. If the time period during which the human sensor 46a detects the user is longer than a threshold value, the power mode may be switched from the power saving mode to the drive mode. In this case, the power control unit 56 may switch the power mode in stages. When a user is not detected by the human sensor 46a, the power control unit 56 maintains the power mode in the power saving mode.

A case is assumed in which the UI 44 is not operated even though there is a person in front of the ultrasound diagnostic apparatus 10. Therefore, the power control unit 56 may control the power mode using the detection result of the human sensor 46a and the presence or absence of an operation on the UI 44.

For example, when the power mode is the drive mode and the human sensor 46a does not detect the user and no operation on the UI 44 (for example, the operation panel 14) is detected, the power control unit 56 controls the power Switch the mode from drive mode to power saving mode. In other cases, the power control unit 56 maintains the power mode in the drive mode.

If the time period in which the human sensor 46a does not detect the user is equal to or greater than the threshold value, and the time period in which no operation on the UI 44 is detected is equal to or greater than the threshold value, the power control unit 56 changes the power mode from the drive mode to the power saving mode. You can also switch to the mode. In other cases, the power control unit 56 maintains the power mode in the drive mode.

When the power mode is the power saving mode, if the human sensor 46a detects a user or an operation on the UI 44 is detected, the power control unit 56 switches the power mode from the power saving mode to the drive mode. You can. In this case, the power control unit 56 may switch the power mode in stages.

(Example 2: Power control depending on whether the display 16 is folded)
In the second embodiment, the power control unit 56 controls the power mode based on the detection result of the magnetic sensor or the detection switch.

The determining unit 54 determines whether the display 16 is folded toward the front side of the ultrasound diagnostic apparatus 10 based on the detection result of the magnetic sensor or the detection switch. The determining unit 54 determines that the ultrasound diagnostic apparatus 10 is not in use when the display 16 is folded, and determines that the ultrasound diagnostic apparatus 10 is in use when the display 16 is not folded. . When the display 16 is folded, the determination unit 54 may determine that the ultrasound diagnostic apparatus 10 is moving or may determine that the ultrasound diagnostic apparatus 10 is about to be moved.

When the power mode is the drive mode and it is determined that the display 16 is folded, the power control unit 56 switches the power mode from the drive mode to the power saving mode. The power control unit 56 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. If it is not determined that the display 16 is folded, the power control unit 56 maintains the power mode in the drive mode.

When the power mode is the power saving mode and the display 16 is not folded, the power control unit 56 may switch the power mode from the power saving mode to the drive mode. In this case, the power control unit 56 may switch the power mode in stages. When the display 16 is folded, the power control unit 56 maintains the power mode in the power saving mode.

(Example 3: Power control depending on whether or not the rear handle 30 is gripped)
In the third embodiment, the power control unit 56 controls the power mode based on the detection results of pressure sensors (for example, a right pressure sensor and a left pressure sensor) installed on the back handle 30.

The determination unit 54 determines whether the back handle 30 is being held by the user based on the detection result of the pressure sensor. The determining unit 54 determines that the ultrasonic diagnostic apparatus 10 is not being used when the back handle 30 is being held by the user. When the back handle 30 is grasped by the user, the determination unit 54 determines that the ultrasound diagnostic apparatus 10 is moving or that the ultrasound diagnostic apparatus 10 is about to be moved. Good too.

The rear handle 30 is installed on the rear side of the operation panel 14 that is operated by the user in order to move the ultrasound diagnostic apparatus 10 or change the position and orientation of the ultrasound diagnostic apparatus 10. Therefore, when the back handle 30 is being held by the user, it is presumed that the ultrasound diagnostic apparatus 10 is being moved or is about to be moved. That is, when using the ultrasonic diagnostic apparatus 10, it is assumed that the user stands or sits in front of the operation panel 14, and the rear handle 30 installed on the back side of the operation panel 14 and display 16 is The fact that the ultrasonic diagnostic apparatus 10 is being held in the hand strongly suggests that the ultrasonic diagnostic apparatus 10 is being moved without being used. Therefore, when the back handle 30 is being held by the user, the determination unit 54 determines that the ultrasound diagnostic apparatus 10 is being moved or is about to be moved.

When the power mode is the drive mode and it is determined that the back handle 30 is being held by the user, the power control unit 56 switches the power mode from the drive mode to the power saving mode. The power control unit 56 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. When the back handle 30 is not grasped by the user, the power control unit 56 maintains the power mode in the drive mode.

If the right side pressure sensor detects that the right handle 30R is being held by the user, and the left pressure sensor detects that the left handle 30L is being held by the user, the determination unit 54 performs an ultrasonic diagnosis. It may be determined that the apparatus 10 is not being used or that the ultrasonic diagnostic apparatus 10 has been moved. When the right side pressure sensor detects that the right side handle 30R is being held by the user, and the left side pressure sensor detects that the left side handle 30L is being held by the user, the back handle 30 is held by both hands of the user. It is assumed that it is being held. In this case, it is presumed that the ultrasound diagnostic apparatus 10 is moving or about to be moved. In other words, it is presumed that the ultrasound diagnostic apparatus 10 is not being used. Therefore, the power control unit 56 switches the power mode from the drive mode to the power saving mode.

If either the right handle 30R or the left handle 30L is not gripped by the user, it is assumed that the ultrasound diagnostic apparatus 10 is not moving or that the ultrasound diagnostic apparatus 10 is not about to be moved. . In this case, it is presumed that the ultrasound diagnostic apparatus 10 is being used, so the power control unit 56 maintains the power mode in the drive mode.

The power control unit 56 switches the power mode from the drive mode to the power saving mode when the force detected by the pressure sensor is greater than or equal to the threshold, and maintains the power mode in the drive mode when the force detected is less than the threshold. You may. The threshold value is determined based on the force applied to the back handle 30 when the user grasps the back handle 30. If the detected force is equal to or greater than the threshold, it is presumed that the back handle 30 is being held by the user. If the detected force is less than the threshold value, it is assumed that the back handle 30 is not being held by the user and that an object or the like is merely being hung on the back handle 30. Therefore, the power control unit 56 switches the power mode from the drive mode to the power saving mode when the detected force is greater than or equal to the threshold, and maintains the power mode in the drive mode when the detected force is less than the threshold. .

If the force detected by the right pressure sensor is equal to or greater than the threshold value, and the force detected by the left pressure sensor is equal to or greater than the threshold value, the power control unit 56 may switch the power mode from the drive mode to the drive mode. . In other cases, the power control unit 56 may maintain the power mode in the drive mode.

The power control unit 56 switches the power mode from the drive mode to the power saving mode when the length of time during which force is detected by the pressure sensor is equal to or greater than the threshold value, and when the length of time is less than the threshold value, The power mode may be maintained in drive mode. If the length of time is equal to or greater than the threshold value, it is presumed that the user is grasping the back handle 30 in order to move the ultrasound diagnostic apparatus 10. If the length of time is less than the threshold, it is presumed that the user touched the back handle 30 temporarily. The threshold value is set to a value that allows the discrimination.

If the length of time during which force is detected by the right pressure sensor is equal to or greater than the threshold value, and the length of time during which force is detected by the left pressure sensor is equal to or greater than the threshold value, the power control unit 56 controls the power The mode may be switched from the drive mode to the power saving mode. In other cases, the power control unit 56 may maintain the power mode in the drive mode.

If it is detected that the back handle 30 is being held by the user according to the above conditions, and then the back handle 30 is temporarily no longer held by the user, the determination unit 54 determines whether the ultrasound diagnostic apparatus 10 may be determined not to be used. For example, if the length of time that the back handle 30 is no longer held by the user is less than the threshold, the determination unit 54 determines that the ultrasound diagnostic apparatus 10 is not being used. Since it is presumed that the back handle 30 is temporarily no longer held by the user while the ultrasound diagnostic apparatus 10 is moving, the determining unit 54 determines that the ultrasound diagnostic apparatus 10 is not being used.

(Example 4: Power control according to detection results of acceleration sensor)
In the fourth embodiment, the power control unit 56 controls the power mode based on the detection result of the acceleration sensor.

The determination unit 54 determines whether the ultrasound diagnostic apparatus 10 is moving based on the detection result of the acceleration sensor. If the ultrasonic diagnostic apparatus 10 is moving, it is presumed that the ultrasonic diagnostic apparatus 10 is not being used.

When the power mode is the drive mode and it is determined that the ultrasound diagnostic apparatus 10 is moving, the power control unit 56 switches the power mode from the drive mode to the power saving mode. The power control unit 56 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. When the ultrasound diagnostic apparatus 10 is not moving, the power control unit 56 maintains the power mode in the drive mode.

The determination unit 54 determines that the ultrasound diagnostic apparatus 10 is moving when the acceleration detected by the acceleration sensor is equal to or higher than the threshold value, and determines that the ultrasound diagnostic apparatus 10 is moving when the detected acceleration is less than the threshold value. It may be determined that the object is not moving. In other words, the power control unit 56 switches the power mode from the drive mode to the power saving mode when the acceleration detected by the acceleration sensor is equal to or higher than the threshold, and maintains the power mode in the drive mode when the acceleration is less than the threshold. You may.

The determination unit 54 determines whether the ultrasound diagnostic apparatus 10 is moving based on the acceleration detected for a predetermined period of time or more, and the power control unit 56 determines whether or not the ultrasound diagnostic apparatus 10 is moving based on the acceleration detected for a predetermined period of time or longer. , may control the power mode. For example, the power control unit 56 switches the power mode from the drive mode to the power saving mode when the length of time that the ultrasound diagnostic apparatus 10 is moving is equal to or greater than the threshold value, and when the length of time is less than the threshold value, the power control unit 56 switches the power mode from the drive mode to the power saving mode. If so, maintain the power mode in drive mode.

Vibration of the ultrasound diagnostic apparatus 10 may be detected by the acceleration sensor, and the power control unit 56 may control the power mode based on the vibration detection result. For example, if the magnitude (eg, amplitude) of the detected vibration is greater than or equal to a threshold value, it is presumed that the ultrasound diagnostic apparatus 10 is moving. In this case, the power control unit 56 switches the power mode from the drive mode to the power saving mode. If the magnitude of the detected vibration is less than the threshold value, it is presumed that the ultrasound diagnostic apparatus 10 is not moving. In this case, the power control unit 56 maintains the power mode in the drive mode.

A process according to one of the first to fourth embodiments described above may be executed, or a process according to a combination of a plurality of these examples may be executed. The implementation to be performed may be specified by the user.

Hereinafter, with reference to FIG. 6, an example of the operation of the ultrasound diagnostic apparatus 10 when switching the power mode from the drive mode to the power saving mode will be described. FIG. 6 shows a flowchart showing the flow of the operation.

First, the power supply 50 is on, and the power mode is the drive mode (S01). In this case, power is supplied from the power supply 50 to each part of the ultrasound diagnostic apparatus 10, and imaging using ultrasound is possible.

If the user is not detected by the human sensor 46a and the UI 44 (for example, the operation panel 14) is not operated (S02, No), the process moves to step S03. If the user is not detected by the human sensor 46a and the UI 44 is not operated, it is presumed that the ultrasound diagnostic apparatus 10 is not in use. It is also assumed that the ultrasound diagnostic apparatus 10 is moving or about to be moved.

If the user is detected by the human sensor 46a (S02, Yes), the process returns to step S01. Furthermore, if the UI 44 is being operated (S02, Yes), the process returns to step S01. That is, when the user is detected by the human sensor 46a or when the UI 44 is operated, it is presumed that the ultrasound diagnostic apparatus 10 is being used. Therefore, the process returns to step S01.

In step S03, it is determined whether the display 16 is folded. If the display 16 is folded (S03, Yes), the process moves to step S04. If the display 16 is folded, it is presumed that the ultrasound diagnostic apparatus 10 is not in use. It is also assumed that the ultrasound diagnostic apparatus 10 is moving or about to be moved.

If the display 16 is not folded (S03, No), the process returns to step S01. If the display 16 is not folded, it is assumed that the ultrasound diagnostic apparatus 10 is being used. Therefore, the process returns to step S01.

In step S04, it is determined whether the back handle 30 is being held by the user. If the back handle 30 is being held by the user (S04, Yes), the process moves to step S05. If the back handle 30 is being held by the user, it is assumed that the ultrasound diagnostic apparatus 10 is not being used. It is also assumed that the ultrasound diagnostic apparatus 10 is moving or about to be moved.

If the back handle 30 is not held by the user (S04, No), the process returns to step S01. If the back handle 30 is not held by the user, it is presumed that the ultrasound diagnostic apparatus 10 is being used. Therefore, the process returns to step S01.

In step S05, it is determined whether the ultrasound diagnostic apparatus 10 is actually moving. If the ultrasound diagnostic apparatus 10 is actually moving (S05, Yes), the power control unit 56 switches the power mode from the drive mode to the power saving mode (S06). As described above, the power control unit 56 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages.

If the ultrasound diagnostic apparatus 10 is not actually moving (S05, No), the process returns to step S01. If the ultrasound diagnostic apparatus 10 is not actually moving, it is presumed that the ultrasound diagnostic apparatus 10 is being used. Therefore, the process returns to step S01.

The processing in steps S02 to S05 described above is only an example, and the power mode may be controlled by executing at least one of the processing in steps S02 to S05. For example, a process selected by the user from among the processes in steps S02 to S05 may be executed.

The order in which each of the processes in steps S02 to S05 is executed is an example, and each process may be executed in an order other than the order shown in FIG. 6. The user may select the order.

Further, when switching the power mode from the drive mode to the power saving mode, the power control section 56 may change the type of power saving mode according to the determination result by the determining section 54.

For example, if the acceleration sensor detects that the ultrasound diagnostic apparatus 10 is actually moving, it is presumed that there is no possibility that the ultrasound diagnostic apparatus 10 is being used. Therefore, the power control unit 56 may switch the power mode from the drive mode to the power off mode.

If the back handle 30 is being held by the user, it is assumed that the ultrasonic diagnostic apparatus 10 is likely to be moving or about to be moved. Therefore, the power control unit 56 may switch the power mode from the drive mode to the power off mode.

Even if the user is not detected by the human sensor 46a or the UI 44 is not operated, there is a possibility that the user will be detected by the human sensor 46a or the UI 44 will be operated. Therefore, the power control unit 56 may switch the power mode to standby mode or hibernation mode without switching the power mode from drive mode to power off mode.

As described above, according to the ultrasonic diagnostic apparatus 10 according to the first embodiment, when the ultrasonic diagnostic apparatus 10 is not used, when the ultrasonic diagnostic apparatus 10 is moving, or when the ultrasonic diagnostic apparatus 10 is about to be moved, the power mode is switched from the drive mode to the power saving mode without the user operating the power button or the like. Therefore, the user's effort to operate the power button and the like is reduced.

Hereinafter, with reference to FIG. 7, an example of the operation of the ultrasound diagnostic apparatus 10 when switching the power mode from the power saving mode to the drive mode will be described. FIG. 7 shows a flowchart showing the flow of the operation.

The power mode is the power saving mode (S11). That is, the power mode is power off mode, standby mode, or hibernation mode.

If the ultrasound diagnostic apparatus 10 is actually moving (S12, Yes), the process returns to step S11. Since it is presumed that the ultrasound diagnostic apparatus 10 is not in use, the process returns to step S11.

If the ultrasound diagnostic apparatus 10 is not actually moving (S12, No), the process moves to step S13.

In step S13, it is determined whether the back handle 30 is being held by the user. If the back handle 30 is being held by the user (S13, Yes), the process returns to step S11. If the back handle 30 is being held by the user, it is assumed that the ultrasound diagnostic apparatus 10 will not be used, and the process returns to step S11.

If the back handle 30 is not held by the user (S13, No), the process moves to step S14.

In step S14, it is determined whether the display 16 is folded. If the display 16 is folded (S14, Yes), the process returns to step S11. If the display 16 is folded, it is presumed that the ultrasonic diagnostic apparatus 10 will not be used, so the process returns to step S11.

If the display 16 is not folded (S14, No), the process moves to step S15.

In step S15, it is determined whether or not the user is detected by the human sensor 46a, and it is determined whether or not the UI 44 is being operated.

If the user is not detected by the human sensor 46a and the UI 44 (for example, the operation panel 14) is not operated (S15, No), the process moves to step S11. In this case, it is presumed that the ultrasound diagnostic apparatus 10 will not be used, so the process moves to step S11.

When the user is detected by the human sensor 46a (S15, Yes), the power control unit 56 switches the power mode from the power saving mode to the drive mode (S16). If the UI 44 is being operated (S15, Yes), the power control unit 56 may switch the power mode from the power saving mode to the drive mode. When the user is detected by the human sensor 46a and the UI 44 is being operated, the power control unit 56 may switch the power mode from the power saving mode to the drive mode. When the user is detected by the human sensor 46a or when the UI 44 is operated, it is assumed that the ultrasonic diagnostic apparatus 10 is used, so the power control unit 56 changes the power mode from the power saving mode. Switch to drive mode.

The processing in steps S12 to S15 described above is merely an example, and the power mode may be controlled by executing at least one of the processing in steps S12 to S15. For example, a process selected by the user from among the processes in steps S12 to S15 may be executed.

The order in which the respective processes of steps S12 to S15 are executed is an example, and each process may be executed in an order other than the order shown in FIG. 7. The user may select the order.

The power control unit 56 may switch the power mode in stages.

For example, when the power mode is the power off mode and movement of the ultrasound diagnostic apparatus 10 is not detected, the power control unit 56 may switch the power mode from the power off mode to a standby mode or a hibernation mode. Thereafter, when the user is detected by the human sensor 46a, when the UI 44 is operated, or when the display 16 is no longer folded, the power control unit 56 changes the power mode from standby mode or hibernation mode to drive mode. You may switch.

When the power mode is the power off mode, if the user is detected by the human sensor 46a, if the UI 44 is operated, or if the display 16 is no longer folded, the power control unit 56 changes the power mode to the power off mode. may be switched from power off mode to drive mode.

As described above, according to the ultrasound diagnostic apparatus 10 according to the first embodiment, the power mode can be switched from the power saving mode to the drive mode without the user operating the power button or the like. Therefore, the user's effort to operate the power button and the like is reduced. For example, when diagnosing an emergency or the like, it is possible to diagnose earlier than when the user operates the power supply.

According to the ultrasonic diagnostic apparatus 10 according to the first embodiment, for example, the user does not need to operate the power supply 50 every time the ultrasonic diagnostic apparatus 10 is moved, so the burden on the user due to this operation is reduced. Ru.

<Second embodiment>
An ultrasound diagnostic apparatus according to a second embodiment will be described with reference to FIGS. 8 and 9. 8 and 9 are perspective views showing an ultrasound diagnostic apparatus 60 according to the second embodiment.

The ultrasound diagnostic device 60 is a device that generates ultrasound images by transmitting and receiving ultrasound waves. The ultrasound diagnostic device 60 is a portable device. The ultrasonic diagnostic apparatus 60 includes, as an example, a probe (not shown), a main body 62, and a display 64.

The main body 62 includes a transmitting/receiving unit that transmits and receives ultrasound through a probe, a signal processing unit that processes a received signal from the probe, an image generation unit that generates an ultrasound image based on a signal from the signal processing unit, and an ultrasound diagnosis unit. It includes a battery that supplies power to each part of the apparatus 60, a control device that controls each part of the ultrasonic diagnostic apparatus 60, and the like.

The display 64 is, for example, a touch panel display, and displays ultrasound images and various information. The display 64 may include a control device that controls each part of the display 64 and a battery that supplies power to each part of the display 64. Furthermore, the display 64 may include an image generation section that generates an ultrasound image based on the signal from the signal processing section described above.

For example, the main body 62 and the display 64 are separate devices, and each is a portable device. The main body 62 and the display 64 can operate when they are separated, or can operate when they are coupled. The main body 62 and the display 64 are electrically connected to each other by a wireless communication method when they are separated. When the main body 62 and the display 64 are coupled, they are electrically connected to each other by a wired communication method. Of course, the main body 62 and the display 64 may not be separate devices, but may be an integrated device.

The display 64 is rotatable toward or away from the main body 62 about a shaft 66 as a rotation axis. For example, the rotation is realized by a hinge mechanism or the like. In the example shown in FIG. 8, the display 64 is rotated in a direction away from the main body 62 about a shaft 66, and this state is a state in which the display 64 stands up. In the example shown in FIG. 9, the display 64 is rotated in the direction of the main body 62 about the axis 66 (see arrow B in FIG. 8), and in this state, the display 64 is folded. be.

Further, a handle is installed on the main body 62, and the handle is grasped by the user when carrying the ultrasonic diagnostic apparatus 60.

The functions of the ultrasonic diagnostic apparatus 60 will be described below with reference to FIG. 10. FIG. 9 is a block diagram showing the functions of the ultrasound diagnostic apparatus 60.

The ultrasonic diagnostic apparatus 60 includes, for example, a probe 68, a transmitter/receiver 70, a signal processor 72, an image generator 74, a UI 76, a sensor 78, a storage device 80, a power source 82, and a controller 84. including.

Like the probe 36 according to the first embodiment, the probe 68 includes a 1D array transducer or a 2D array transducer. As an ultrasonic scanning method using the probe 68, sector scanning, linear scanning, convex scanning, etc. are used.

The transmitting/receiving section 70 functions as a transmitting beam former and a receiving beam former, similarly to the transmitting/receiving section 70 according to the first embodiment, and outputs beam data based on the received signal to the signal processing section 72.

Similar to the signal processing unit 40 according to the first embodiment, the signal processing unit 72 is a device that applies signal processing such as detection, logarithmic compression, and coordinate transformation to the beam data output from the transmitting/receiving unit 70. . The beam data after signal processing is output to the image generation section 74. The beam data after signal processing may be stored in the storage device 80.

Similar to the image generating section 42 according to the first embodiment, the image generating section 74 is a device (for example, a DSC (digital scan converter)) having a coordinate conversion function, an interpolation processing function, etc. An ultrasound image (for example, a B-mode tomographic image) is generated based on the obtained beam data. The ultrasound image may be stored in storage device 80. For example, an ultrasound image is displayed on display 64.

The UI 76 is a user interface and includes a display (for example, the display 64) and an input device. For example, the display 64 is a touch panel display that functions as both a display device and an input device.

Sensor 78 includes various sensors. For example, the sensor 78 includes at least one of a human sensor, a pressure sensor, an acceleration sensor, a magnetic sensor, and a gyro sensor. The detection result of sensor 78 is output to control device 84 .

For example, a gyro sensor is installed in the main body 62, and the inclination (angle) of the main body 62 is detected by the gyro sensor. As the gyro sensor, for example, a known gyro sensor is used. Note that the tilt of the main body 62 may be detected by an acceleration sensor.

The storage device 80 is a device that configures one or more storage areas for storing data. The storage device 48 is, for example, a hard disk drive (HDD), a solid state drive (SSD), various types of memory (for example, RAM, DRAM, ROM, etc.), other storage devices (for example, an optical disk, etc.), or a combination thereof. . For example, ultrasound images and the like are stored in the storage device 80.

The power supply 82 is constituted by a power supply circuit, and supplies power to each part of the ultrasonic diagnostic apparatus 60. The power supply circuit is an AC (Alternate Current)/DC (Direct Current) conversion circuit. Further, the power source 82 includes a battery.

The control device 84 controls the operation of each part of the ultrasound diagnostic apparatus 60. For example, the control device 84 includes a determination section 86 and a power control section 88, and controls the power mode of the ultrasound diagnostic apparatus 60.

Similar to the determining unit 54 according to the first embodiment, the determining unit 86 determines whether the ultrasound diagnostic apparatus 60 is moving based on the usage status of the ultrasound diagnostic apparatus 60. Specifically, the determination unit 86 determines whether the ultrasound diagnostic apparatus 60 is moving based on the detection result by the sensor 78. The determination unit 86 may determine whether the ultrasonic diagnostic apparatus 60 is being used based on the detection result by the sensor 78.

Similar to the power control unit 88 according to the first embodiment, the power control unit 88 controls the power mode of the ultrasound diagnostic apparatus 60 based on the determination result of the determination unit 86. For example, when the determining unit 86 determines that the ultrasound diagnostic apparatus 60 is moving, the power control unit 88 switches the power mode of the ultrasound diagnostic apparatus 60 from the drive mode to the power saving mode. The technical significance of each of the drive mode and the power saving mode is the same as that of the first embodiment.

Each embodiment of the operation of the ultrasonic diagnostic apparatus 60 will be described below.

(Example 5: Power control according to the inclination of the ultrasound diagnostic device 60)
In the fifth embodiment, the power control unit 88 controls the power mode based on the detection result of the gyro sensor.

The determining unit 86 determines whether the ultrasonic diagnostic apparatus 60 is moving based on the detection result of the gyro sensor. For example, when the inclination (angle) detected by the gyro sensor is equal to or greater than the threshold, the determination unit 86 determines that the ultrasonic diagnostic apparatus 60 is being carried by the user and is moving, and the detected inclination (angle) ) is less than the threshold, the ultrasonic diagnostic apparatus 60 determines that it is not being carried by the user. Note that the tilt of the ultrasound diagnostic apparatus 60 may be detected by an acceleration sensor.

For example, the angle of the ultrasonic diagnostic apparatus 60 when the bottom surface of the main body 62 is installed parallel to the horizontal direction (for example, a direction perpendicular to the direction in which gravity acts) is determined as the reference angle. The angle of the main body 62 from the reference angle is detected by a gyro sensor or an acceleration sensor. The determination unit 86 determines that the ultrasound diagnostic apparatus 60 is being carried by the user when the detected angle is greater than or equal to the threshold, and determines that the ultrasound diagnostic apparatus 60 is being carried by the user when the detected angle is less than the threshold. 60 is determined not to be carried by the user. This criterion is only an example, and another criterion may be set.

When the power mode is the drive mode and the detected slope is equal to or greater than the threshold, the power control unit 88 switches the power mode from the drive mode to the power saving mode. The power control unit 88 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. If the detected tilt is less than the threshold, the power control unit 88 maintains the power mode in the drive mode.

When the power mode is the power saving mode and the detected tilt is less than the threshold value, the power control unit 88 may switch the power mode from the power saving mode to the drive mode. In this case, the power control unit 88 may switch the power mode in stages.

(Example 6: Power control depending on whether the display 64 is folded)
In the sixth embodiment, the power control unit 88 switches the power mode depending on whether the display 64 is folded. For example, a sensor that detects whether the display 64 is folded is installed on the main body 62 or the display 64, and the determination unit 86 determines whether the display 64 is folded based on the detection result of the sensor.

When the power mode is the drive mode, if it is determined that the display 64 is folded, the power control unit 88 switches the power mode from the drive mode to the power saving mode. The power control unit 88 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages. If it is not determined that the display 64 is folded, the power control unit 88 maintains the power mode in the drive mode.

When the power mode is the power saving mode and the display 64 is not folded, the power control unit 88 may switch the power mode from the power saving mode to the drive mode. In this case, the power control unit 88 may switch the power mode in stages. When the display 64 is folded, the power control unit 88 maintains the power mode in the power saving mode.

In addition to the above embodiments, similarly to the first embodiment, the determination unit 86 may determine whether or not the ultrasound diagnostic apparatus 60 is moving using an acceleration sensor, or may determine whether or not the ultrasound diagnostic apparatus 60 is moving using an acceleration sensor. Based on the results, it may be determined whether the ultrasound diagnostic apparatus 60 is in use. The power control unit 88 may control the power mode based on these determination results, similar to the first embodiment.

Hereinafter, with reference to FIG. 11, an example of the operation of the ultrasound diagnostic apparatus 60 when switching the power mode from the drive mode to the power saving mode will be described. FIG. 11 shows a flowchart showing the flow of the operation.

First, the power supply 82 is on, and the power mode is the drive mode (S21). In this case, output is supplied from the power supply 82 to each part of the ultrasound diagnostic apparatus 60, and imaging using ultrasound is possible. Power may be supplied to each part of the ultrasound diagnostic apparatus 60 from a battery included in the power supply 82.

If the display 64 is folded (S22, Yes), the process moves to step S23. If the display 64 is folded, it is presumed that the ultrasound diagnostic apparatus 60 is not in use. It is also assumed that the ultrasound diagnostic apparatus 60 is moving or about to be moved.

If the display 64 is not folded (S22, No), the process returns to step S21. If the display 64 is not folded, it is assumed that the ultrasound diagnostic device 60 is being used. Therefore, the process returns to step S21.

In step S23, it is determined whether the ultrasound diagnostic apparatus 60 is tilted. If the inclination (angle) of the ultrasound diagnostic apparatus 60 is equal to or greater than the threshold (S23, Yes), the process moves to step S24. If the inclination (angle) of the ultrasound diagnostic device 60 is equal to or greater than the threshold value, it is presumed that the ultrasound diagnostic device 60 is not being used and is being moved or is about to be moved.

If the inclination (angle) of the ultrasound diagnostic apparatus 60 is less than the threshold (S23, No), the process returns to step S21. If the inclination (angle) of the ultrasound diagnostic device 60 is less than the threshold value, it is assumed that the ultrasound diagnostic device 60 is not moving or is not about to be moved, and the ultrasound diagnostic device 60 is not being used. It is assumed that there are. Therefore, the process returns to step S21.

In step S24, it is determined whether the ultrasound diagnostic apparatus 60 is actually moving. If the ultrasound diagnostic apparatus 60 is actually moving (S24, Yes), the power control unit 88 switches the power mode from the drive mode to the power saving mode (S25). As described above, the power control unit 88 may switch the power mode to a predetermined power saving mode, or may switch the power mode in stages.

If the ultrasound diagnostic apparatus 60 is not actually moving (S24, No), the process returns to step S21. If the ultrasound diagnostic device 60 is not actually moving, it is presumed that the ultrasound diagnostic device 60 is being used. Therefore, the process returns to step S21.

The processing in steps S22 to S24 described above is merely an example, and the power mode may be controlled by executing at least one of the processing in steps S22 to S24. For example, a process selected by the user from among the processes in steps S22 to S24 may be executed.

The order in which the processes of steps S22 to S24 are executed is merely an example, and the processes may be executed in an order other than the order shown in FIG. 11. The user may select the order.

Based on the inclination of the ultrasound diagnostic device 60, it is estimated whether the ultrasound diagnostic device 60 is moving or not, so the process of step S24 does not need to be executed. In this case, if the tilt of the ultrasound diagnostic apparatus 60 is equal to or greater than the threshold (S23, Yes), the power control unit 88 switches the power mode from the drive mode to the power saving mode (S25).

Further, when switching the power mode from the drive mode to the power saving mode, the power control section 88 may change the type of power saving mode according to the determination result by the determining section 86.

For example, if the inclination (angle) of the ultrasound diagnostic device 60 is equal to or greater than the threshold value, it is estimated that the possibility that the ultrasound diagnostic device 60 will be used is low. Therefore, the power control unit 88 may switch the power mode from the drive mode to the power off mode.

Display 64 may be temporarily folded, and then use of ultrasound diagnostic apparatus 60 may be resumed. In this case, the power control unit 88 does not switch the power mode from drive mode to power off mode, but switches it to standby mode or hibernation mode. Thereby, compared to the case where the power mode is switched from the drive mode to the power off mode, the time required to return from the power saving mode to the drive mode can be shortened.

As described above, according to the ultrasound diagnostic device 60 according to the second embodiment, when the ultrasound diagnostic device 60 is not used, when the ultrasound diagnostic device 60 is moving, or when the ultrasound diagnostic device 60 is about to be moved, the power mode is switched from the drive mode to the power saving mode without the user operating the power button or the like. Therefore, the user's effort to operate the power button and the like is reduced.

Hereinafter, with reference to FIG. 12, an example of the operation of the ultrasound diagnostic apparatus 60 when switching the power mode from the power saving mode to the drive mode will be described. FIG. 12 shows a flowchart showing the flow of the operation.

The power mode is power saving mode (S31). That is, the power mode is power off mode, standby mode, or hibernation mode.

If the ultrasound diagnostic apparatus 60 is actually moving (S32, Yes), the process returns to step S31. Since it is presumed that the ultrasound diagnostic apparatus 60 is not in use, the process returns to step S31.

If the ultrasound diagnostic apparatus 60 is not actually moving (S32, No), the process moves to step S33.

In step S33, it is determined whether the ultrasound diagnostic apparatus 60 is tilted. If the inclination (angle) of the ultrasound diagnostic apparatus 60 is equal to or greater than the threshold (S33, Yes), the process returns to step S31. If the inclination (angle) of the ultrasound diagnostic device 60 is equal to or greater than the threshold value, it is assumed that the ultrasound diagnostic device 60 is moving or about to be moved, and the process returns to step S31.

If the inclination (angle) of the ultrasound diagnostic apparatus 60 is less than the threshold (S33, No), the process moves to step S34.

In step S34, it is determined whether the display 64 is folded. If the display 64 is folded (S34, Yes), the process returns to step S31. If the display 64 is folded, it is presumed that the ultrasound diagnostic apparatus 60 will not be used, so the process returns to step S31.

If the display 64 is not folded (S34, No), the power control unit 88 switches the power mode from the power saving mode to the drive mode (S35). If the display 64 is not folded, it is assumed that the ultrasonic diagnostic apparatus 60 will be used, so the power control unit 88 switches the power mode from the power saving mode to the drive mode.

The processing in steps S32 to S34 described above is merely an example, and the power mode may be controlled by executing at least one of the processing in steps S32 to S34. For example, a process selected by the user from among the processes in steps S32 to S34 may be executed.

The order in which the respective processes of steps S32 to S34 are executed is an example, and each process may be executed in an order other than the order shown in FIG. 12. The user may select the order.

Based on the inclination of the ultrasound diagnostic device 60, it is estimated whether the ultrasound diagnostic device 60 is moving or not, so the process of step S32 does not need to be executed.

The power control unit 88 may switch the power mode in stages.

For example, when the power mode is the power off mode and the tilt (angle) of the ultrasound diagnostic apparatus 60 is less than a threshold, the power control unit 88 switches the power mode from the power off mode to the standby mode or hibernation mode. You can. Thereafter, when the display 64 is no longer folded, the power control unit 88 may switch the power mode from standby mode or hibernation mode to drive mode.

As described above, according to the ultrasound diagnostic apparatus 60 according to the second embodiment, the power mode can be switched from the power saving mode to the drive mode without the user operating the power button or the like. Therefore, the user's effort to operate the power button and the like is reduced. For example, when diagnosing an emergency or the like, it is possible to diagnose earlier than when the user operates the power supply.

According to the ultrasound diagnostic apparatus 60 according to the second embodiment, for example, the user does not need to operate the power supply 50 every time the ultrasound diagnostic apparatus 10 is moved, so the burden on the user due to this operation is reduced. Ru.

Further, since the ultrasonic diagnostic apparatus 60 is prevented from being moved while the power source 82 remains on, the duration of the battery installed in the ultrasonic diagnostic apparatus 60 can be extended.
