Description

  Embodiments described herein relate generally to an ultrasonic diagnostic system, an ultrasonic diagnostic apparatus, and a terminal device.

  2. Description of the Related Art Conventionally, there is known an ultrasonic diagnostic apparatus that transmits ultrasonic waves from an ultrasonic probe to a subject, receives the reflected waves, and displays an ultrasonic image that has been imaged on a monitor. The operator checks the ultrasonic image displayed on the monitor while operating the console provided in the ultrasonic probe or ultrasonic diagnostic apparatus. However, depending on the examination site of the subject, the console may be operated or the monitor may be checked. It was sometimes difficult. For example, in the case of a lower limb examination, since an ultrasonic probe is brought into contact with a lower limb of a subject in a sitting position, an operator often performs an examination while sitting near the floor as compared with an abdominal examination, Since the operation is performed at a position away from the apparatus main body provided with the console and the monitor, the operation of the operation panel and the visibility of the monitor image are remarkably lowered. Some conventional ultrasound diagnostic devices have different consoles depending on the diagnosis target, but when there is not enough operation function or the visibility of the ultrasound image displayed on the monitor is poor, it is difficult to confirm the image There was a problem.

  Hereinafter, an ultrasonic diagnostic system, an ultrasonic diagnostic apparatus, and a terminal device according to embodiments will be described in detail with reference to the accompanying drawings. In the following description, common constituent elements are given common reference numerals, and redundant description is omitted.

  FIG. 1 is a block diagram illustrating a system configuration of an ultrasonic diagnostic system according to the embodiment. As shown in FIG. 1, the ultrasonic diagnostic system includes an ultrasonic diagnostic apparatus 100 that collects ultrasonic image data from a subject P and a terminal device 2 that is connected to the ultrasonic diagnostic apparatus 100 via a communication line R. Prepare.

  The ultrasonic diagnostic apparatus 100 includes an ultrasonic probe 10, an apparatus main body 20, a monitor 30, and an input device 40. The device main body 20 is connected to the terminal device 2 via the communication line R so that they can communicate with each other.

  The ultrasonic probe 10 includes, for example, a plurality of piezoelectric vibrators as a plurality of acoustic elements (acoustic element group). The plurality of piezoelectric vibrators generate ultrasonic waves based on a drive signal supplied from a transmission / reception unit 21 included in the apparatus main body 20 described later. The ultrasonic probe 10 receives a reflected wave from the subject P and converts it into an electrical signal. The ultrasonic probe 10 includes a matching layer provided in the piezoelectric vibrator, a backing material that prevents propagation of ultrasonic waves from the piezoelectric vibrator to the rear, and the like.

  When ultrasonic waves are transmitted from the ultrasonic probe 10 to the subject P, the transmitted ultrasonic waves are reflected one after another at the discontinuous surface of the acoustic impedance in the body tissue of the subject P, and the ultrasonic probe as a reflected wave signal Received by a plurality of piezoelectric vibrators 10. The amplitude of the received reflected wave signal depends on the difference in acoustic impedance at the discontinuous surface where the ultrasonic wave is reflected. Note that the reflected wave signal when the transmitted ultrasonic pulse is reflected by the moving blood flow or the surface of the heart wall depends on the velocity component of the moving object in the ultrasonic transmission direction due to the Doppler effect. And undergoes a frequency shift.

  Here, the ultrasound probe 10 is an ultrasound probe capable of scanning the subject P in two dimensions with ultrasound and scanning the subject P in three dimensions. Specifically, the ultrasonic probe 10 scans the subject P two-dimensionally with a plurality of piezoelectric vibrators (vibrator groups) arranged in a line, and moves the plurality of piezoelectric vibrators to a predetermined angle (swing). It is a mechanical 4D probe that performs three-dimensional scanning of ultrasonic waves by mechanically swinging at a moving angle.

  The input device 40 includes a mouse, a keyboard, a button, a panel switch, a touch command screen, a foot switch, a trackball, a joystick, and the like, receives various operation instructions from an operator of the ultrasonic diagnostic apparatus 100, and An operation signal S1 corresponding to the received operation instruction is transmitted.

  The monitor 30 displays a GUI (Graphical User Interface) for an operator of the ultrasonic diagnostic apparatus 100 to input various operation instructions using the input device 40, and displays an ultrasonic image generated in the apparatus main body 20 or the like. Or display. The image displayed on the monitor 30 is a main display image G1 that is generated by an image processing unit 23 described later and output to the monitor 30 via the interface unit 26.

  The apparatus main body 20 is an apparatus that performs overall control of ultrasonic image capturing. Specifically, the apparatus main body 20 generates ultrasonic image data based on the reflected wave received by the ultrasonic probe 10, thereby superimposing the subject P. It is a device that collects sonic images. For example, as shown in FIG. 1, the apparatus main body 20 includes a transmission / reception unit 21, a signal processing unit 22, an image processing unit 23, a data storage unit 24, a control unit 25, and an interface unit 26.

  The transmission / reception unit 21 includes a trigger generation circuit, a transmission delay circuit, a pulser circuit, and the like, and supplies a drive signal to the ultrasonic probe 10. The pulsar circuit repeatedly generates rate pulses for forming transmission ultrasonic waves at a predetermined rate frequency. The transmission delay circuit also sets the delay time for each piezoelectric vibrator necessary for determining the transmission directivity by focusing the ultrasonic wave generated from the ultrasonic probe 10 into a beam shape at each rate at which the pulsar circuit generates. Give to pulse. The trigger generation circuit applies a drive signal (drive pulse) to the ultrasonic probe 10 at a timing based on the rate pulse. That is, the transmission delay circuit arbitrarily adjusts the transmission direction from the piezoelectric vibrator surface by changing the delay time given to each rate pulse.

  The transmission / reception unit 21 has a function capable of instantaneously changing a transmission frequency, a transmission drive voltage, and the like in order to execute a predetermined scan sequence based on an instruction from the control unit 25 described later. In particular, the change of the transmission drive voltage is realized by a linear amplifier type transmission circuit capable of instantaneously switching the value or a mechanism for electrically switching a plurality of power supply units.

  The transmission / reception unit 21 includes an amplifier circuit, an A / D converter, an adder, a phase detection circuit, and the like, and performs various processes on the reflected wave signal received by the ultrasonic probe 10 to generate reflected wave data. To do. The amplifier circuit amplifies the reflected wave signal for each channel and performs gain correction processing. The A / D converter performs A / D conversion on the gain-corrected reflected wave signal and gives a delay time necessary for determining reception directivity to the digital data. The adder performs addition processing of the reflected wave signal processed by the A / D converter. By the addition processing of the adder, the reflection component from the direction corresponding to the reception directivity of the reflected wave signal is emphasized. The phase detection circuit converts the output signal of the adder into a baseband in-phase signal (I signal, I: In-phase) and a quadrature signal (Q signal, Q: Quadrature-phase). Then, the phase detection circuit outputs the I signal and the Q signal (IQ signal) to the signal processing unit 22 at the subsequent stage. Note that the data before processing by the phase detection circuit is also called an RF signal. Hereinafter, “IQ signal and RF signal” generated based on the reflected wave of the ultrasonic wave are collectively referred to as “reflected wave data”.

  As described above, the transmission / reception unit 21 controls transmission directivity and reception directivity in ultrasonic transmission / reception. That is, the transmission / reception unit 21 functions as a transmission beam former and a reception beam former. Here, the transmission / reception unit 21 performs two-dimensional scanning (cross-sectional scanning) on the subject P by transmitting a two-dimensional ultrasonic beam from the transducer group of the ultrasonic probe 10 that is a mechanical 4D probe. Thus, the transmission / reception unit 21 generates two-dimensional reflected wave data.

  Further, the transmission / reception unit 21 performs three-dimensional scanning by two-dimensional scanning of a plurality of cross sections by swinging the transducer group of the ultrasonic probe 10 that is a mechanical 4D probe within a predetermined range at a predetermined swing speed. . When three-dimensional scanning is performed, the transmission / reception unit 21 generates three-dimensional reflected wave data from the reflected wave signals of the plurality of cross sections. The operator sets a range for performing three-dimensional scanning by setting a swing angle (swing range) via the input device 40.

  The signal processing unit 22 receives the reflected wave data from the transmission / reception unit 21, performs logarithmic amplification, envelope detection processing, and the like, and generates data (B-mode data) in which the signal intensity is expressed by brightness. Further, the signal processing unit 22 performs frequency analysis on velocity information from the reflected wave data received from the transmission / reception unit 21, extracts blood flow, tissue, and contrast agent echo components due to the Doppler effect, and moves average velocity, dispersion, power, and the like. Data (Doppler data) obtained by extracting body information for multiple points is generated.

  Here, the signal processing unit 22 can process both two-dimensional reflected wave data and three-dimensional reflected wave data. That is, the signal processing unit 22 generates two-dimensional B-mode data from the two-dimensional reflected wave data, and generates three-dimensional B-mode data from the three-dimensional reflected wave data. Further, the signal processing unit 22 generates two-dimensional Doppler data from the two-dimensional reflected wave data, and generates three-dimensional Doppler data from the three-dimensional reflected wave data.

  The image processing unit 23 generates ultrasonic image data from the data generated by the signal processing unit 22. That is, the image processing unit 23 generates B-mode image data in which the intensity of the reflected wave is represented by luminance from the B-mode data. Further, the image processing unit 23 generates Doppler image data as an average speed image, a dispersed image, a power image, or a combination image representing moving body information from the Doppler data. The image processing unit 23 can also generate a composite image in which character information of various parameters, scales, body marks, and the like are combined with the ultrasonic image.

  The image processing unit 23 performs image processing for changing at least one of the resolution and the frame rate on the image data under the control of the control unit 25. Specifically, the image data of the moving image or the still image is up-converted or down-converted to generate an image having a lower resolution / higher resolution than the resolution of the original image. Also, by performing frame interpolation or frame extraction on the moving image image data, a moving image having a higher frame rate / lower frame rate than the original moving image is generated. As another method example, there is a method of separately creating images having different sizes and frame rates at the stage of converting original image data such as B-mode data into display image data.

  Further, the image processing unit 23 converts (scan converts) the scanning line signal sequence of ultrasonic scanning into a scanning line signal sequence of a video format represented by a television or the like, and generates ultrasonic image data as a display image. To do. In addition to the scan conversion, the image processing unit 23 performs various image processing, such as image processing (smoothing processing) for regenerating an average luminance image using a plurality of image frames after scan conversion, Image processing (edge enhancement processing) using a differential filter is performed in the image.

  That is, B-mode data and Doppler data are ultrasonic image data before the scan conversion process, and data generated by the image processing unit 23 is ultrasonic image data for display after the scan conversion process.

  In addition, the image processing unit 23 generates three-dimensional B-mode image data by performing coordinate conversion on the three-dimensional B-mode data generated by the signal processing unit 22. In addition, the image processing unit 23 generates three-dimensional color Doppler image data by performing coordinate conversion on the three-dimensional Doppler data generated by the signal processing unit 22. That is, the image processing unit 23 generates “three-dimensional B-mode image data and three-dimensional color Doppler image data” as “volume data that is three-dimensional ultrasound image data”.

  In addition, the image processing unit 23 performs rendering processing on the volume data in order to generate various two-dimensional image data for displaying the volume data on the monitor 30 or the terminal device 2. The rendering processing performed by the image processing unit 23 includes processing for generating MPR image data from volume data by performing a cross-section reconstruction method (MPR: Multi Planer Reconstruction). The rendering processing performed by the image processing unit 23 includes processing for performing “Curved MPR” on volume data and processing for performing “Intensity Projection” on volume data. The rendering processing performed by the image processing unit 23 includes volume rendering (VR) processing that generates two-dimensional image data reflecting three-dimensional information.

  Further, the image processing unit 23 displays a GUI for inputting various operation instructions on the monitor 30 under the control of the control unit 25, and displays an ultrasonic image or the like generated in the apparatus main body 20 on the monitor 30. A main display image G1 is generated. Further, the image processing unit 23 displays a GUI for inputting various operation instructions on the terminal device 2 under the control of the control unit 25, and displays an ultrasonic image or the like on the terminal device 2. A sub display image G2 is generated.

  The data storage unit 24 stores various data generated by the apparatus main body 20. For example, the data storage unit 24 includes reflected wave data generated by the transmission / reception unit 21, B-mode data and Doppler data generated by the signal processing unit 22, ultrasonic image data generated by the image processing unit 23, main display image G1, The sub display image G2 is stored. The data storage unit 24 also stores three-dimensional reflected wave data, three-dimensional B-mode data, three-dimensional Doppler data, and three-dimensional ultrasound image data.

  The control unit 25 is a control processor (CPU: Central Processing Unit) that realizes a function as an information processing apparatus, and controls the entire processing of the ultrasonic diagnostic apparatus 100. Specifically, the control unit 25 determines whether the transmission / reception unit 21, the signal processing unit 22, and the image processing unit 23 are based on various operation instructions input from the operator via the input device 40, various control programs, and various data. Control processing. The control unit 25 controls data storage processing in the data storage unit 24. In addition, the control unit 25 controls output of data stored in the data storage unit 24. The control unit 25 includes a display control unit 251 for displaying on the monitor 30 and a communication control unit 252 for controlling transmission / reception between the terminal device 2 connected to the interface unit 26 via the communication line R. (Details will be described later).

  The display control unit 251 causes the image processing unit 23 to generate the main display image G1 to be displayed on the input device 40, and outputs the generated main display image G1 via the interface unit 26 to the monitor 30. The main display image G1 is displayed. Specifically, the display control unit 251 is a main display image including a GUI image and an ultrasonic image stored in the data storage unit 24 in accordance with an operation instruction or various control programs received from the input device 40 or the terminal device 2. G1 is generated by the image processing unit 23. Next, the display control unit 251 outputs the main display image G1 generated by the image processing unit 23 to the monitor 30 via the interface unit 26.

  The communication control unit 252 controls communication with the terminal device 2. Specifically, the communication control unit 252 causes the image processing unit 23 to generate a sub display image G2 to be displayed on the terminal device 2 after performing communication connection with the terminal device 2 via the communication line R. Then, the interface unit 26 transmits the data to the terminal device 2 via the communication line R. At this time, the communication control unit 252 causes the image processing unit 23 to generate the sub display image G2 in which at least one of the resolution and the frame rate is reduced from the main display image G1 in accordance with the data transmission rate on the communication line R. . Thereby, in the terminal device 2, the sub display image G2 can be displayed without delay.

  For example, a 30 fps HD image can be sent to the monitor 30 via the interface unit 26, but generally the transmission rate of the communication line R is lower than that, and only 15 fps SD images may be sent. In such a case, if the main display image G1 of a 30 fps HD image is sent as it is, the display on the terminal device 2 is delayed. In contrast, the image processing unit 23 generates the sub display image G2 in which the main display image G1 of the 30 fps HD image is reduced to the 15 fps SD image in accordance with the data transmission rate on the communication line R, and then the terminal. By transmitting to the device 2, the terminal device 2 can display the sub display image G2 without delay.

  Further, the control unit 25 switches the operation mode applied to the display control unit 251 and the communication control unit 252 based on the relative position of the terminal device 2 with respect to the ultrasound diagnostic apparatus 100 and the attitude of the terminal device 2 (details will be described later). ).

  In addition, the control unit 25 detects the radio wave intensity in wireless communication via the terminal device 2 and the interface unit 26 and the placement of the terminal device 2 on the cradles 261, 261a, and 261b (see FIGS. 3 and 4). The relative position of the terminal device 2 with respect to the ultrasonic diagnostic apparatus 100 is detected. For example, in the case of wireless communication, the position of the terminal device 2 in the three-axis directions of the XYZ with respect to the ultrasonic diagnostic apparatus 100 is detected by detecting radio wave intensity at a plurality of antennas and performing triangulation. In addition to the wireless communication by the interface unit 26, the detection may be performed using a distance sensor such as infrared rays or ultrasonic waves.

  The interface unit 26 is an interface connected to the monitor 30, the input device 40, and the terminal device 2. For example, the main display image G <b> 1 generated by the image processing unit 23 can be output to the monitor 30 by the interface unit 26 under the control of the control unit 25. Further, the operation signal S <b> 1 transmitted from the input device 40 is transferred to the control unit 25 by the interface unit 26. In addition, communication connection with the terminal device 2 is performed via the communication line R under the control of the communication control unit 252, and the sub display image G2 generated by the image processing unit 23 is transmitted to the terminal device 2. Data transmission / reception such as reception of the operation signal S2 transmitted from the terminal device 2 and the attitude of the terminal device 2 is performed.

  Here, the communication line R for the interface unit 26 to communicate with the terminal device 2 is a wired / wireless LAN (Local Area Network), a wired / wireless USB (Universal Serial Bus), Bluetooth (registered trademark), or the like. It may be a combination thereof. For example, when the ultrasound diagnostic apparatus 100 and the terminal device 2 establish a communication session under the control of the communication control unit 252 and the communication unit 130 described later and start a communication connection with each other, the sub display image G2 is displayed. The communication line R for transmitting to the terminal device 2 and the communication line R for receiving the operation signal S2 transmitted by the terminal device 2 may be separated from each other.

  Specifically, after the communication connection is started between ch1 and ch2 of the wireless LAN, the sub display image G2 may be transmitted to the terminal device 2 via ch1 and the operation signal S2 may be received via ch2. Note that examples of communication lines different from each other are not limited to a plurality of wireless LAN channels, but may be WirelessUSB and wireless LAN, or wireless LAN and Bluetooth (registered trademark). As described above, when the transmission of the sub display image G2 and the reception of the operation signal S2 are performed through different communication lines R, the transmission band of the sub display image G2 can be reliably ensured.

  The terminal device 2 is a device that is communicably connected to the ultrasonic diagnostic apparatus 100 via the communication line R and can be used apart from the ultrasonic diagnostic apparatus 100.

  Further, the control unit 25 detects that the terminal device 2 is placed on the cradle 261 by detecting the connection of the terminal device 2 via the charging terminal 262 or the communication terminal 263.

  The installation position of the cradle 261 is not limited to the side surface portion of the apparatus main body 20. For example, as shown in FIG. 4, a cradle 261 a may be provided in a lateral position side by side with the monitor 30. Further, the cradle 261b may be provided at a position below the monitor 30 and in the vicinity of the input device 40 (both the communication terminal and the charging terminal are omitted).

When the position of the terminal device 2 with respect to the ultrasonic diagnostic apparatus 100 is a low position near the floor or when the terminal device 2 is in the vertical orientation (S21: YES), the control unit 25 sets the operation mode to the lower limb. The lower limb inspection mode for performing the inspection is set (S22), and the process proceeds to S24. When the position of the terminal device 2 with respect to the ultrasonic diagnostic apparatus 100 is not at a low position near the floor, or when the attitude of the terminal device 2 is not horizontal but horizontal (S21: NO), the control unit 25 operates The mode is set to an abdominal examination mode for performing an abdominal examination (S23), and the process proceeds to S24.

  In S24, the display control unit 251 and the communication control unit 252 cause the image processing unit 23 to generate the main display image G1 / sub display image G2 according to the operation mode set in S13 to S23. Next, the display control unit 251 displays the main display image G1 on the monitor 30, and the communication control unit 252 performs image output for transmitting the sub display image G2 to the terminal device 2 (S25). The control unit 25 continues the processes of S11 to S25 described above until it is determined that the end instruction is input by the input device 40 or the like and the process is ended (S26: YES).

  Specifically, in the standby mode, since the terminal device 2 is accommodated in the cradle 261 and suspended, the communication control unit 252 does not generate the sub display image G2, and the display control unit 251 G1 is generated. Thereby, in the ultrasonic diagnostic apparatus 100, the main display image G1 is displayed on the monitor 30.

  In the touch pad mode, since the terminal device 2 is housed in the cradle 261b and used as a touch pad for assisting the operation of the input device 40, the communication control unit 252 has a GUI for performing a touch operation. Is generated, and the display control unit 251 generates the main display image G1. As a result, the terminal device 2 displays the sub display image G2 including the GUI for performing the touch operation, and the ultrasound diagnostic apparatus 100 displays the main display image G1 on the monitor 30.

  FIG. 6 is an explanatory diagram illustrating an example when the terminal device 2 is placed on the cradle 261b. As shown in FIG. 6, when the terminal device 2 is placed on the cradle 261 b, a sub-display image G <b> 2 including a keyboard for use as a touch pad is displayed on the terminal device 2. As a result, the operator can use the terminal device 2 as an assisting operation in the input device 40.

  In the second monitor mode, since the terminal device 2 is housed in the cradle 261a and used as a second monitor for assisting the display on the monitor 30, the display control unit 251 generates the main display image G1, The communication control unit 252 generates a sub display image G2 including an image to be displayed as an auxiliary to the main display image G1 (for example, an image of a different type from the image included in the main display image G1). As a result, the terminal device 2 displays the sub display image G2 including the image to be displayed as an auxiliary to the main display image G1, and the ultrasound diagnostic device 100 displays the main display image G1 on the monitor 30. The sub-display image G2 displayed on the second monitor is not limited to the ultrasonic image, but can also display a stored image including other modality images and display an operation function using a GUI.

  FIG. 7 is an explanatory diagram illustrating an example when the terminal device 2 is placed on the cradle 261a. As shown in FIG. 7, when the terminal device 2 is placed on the cradle 261 a, a sub display image G <b> 2 including an image to be displayed as an auxiliary to the main display image G <b> 1 is displayed on the terminal device 2. In the illustrated example, a diagnostic image G11 that is an ultrasound image is displayed in the main display image G1, and an X-ray image of the same patient is read from a server device (not shown) and displayed in the sub-display image G2. Yes. Thus, when the terminal device 2 is placed in the lateral position of the monitor 30, the terminal device 2 may be used as a second monitor. The illustrated example is an example of an image displayed as an auxiliary to the main display image G1, and as another example, a desktop image outside the display area of the main display image G1 is displayed as a sub display image, as in a general second monitor. The structure displayed on G2 may be sufficient.

  In the second console mode, since the operator uses the terminal device 2 away from the device body 20, the display control unit 251 generates the main display image G1, and the communication control unit 252 And a sub display image G2 for displaying an image such as an ultrasonic image. As a result, the terminal device 2 displays the GUI for inputting various operation instructions and the sub-display image G2 including an image such as an ultrasound image, and the ultrasound diagnostic device 100 displays the main display image on the monitor 30. G1 is displayed. Further, when in the second console mode, the communication control unit 252 generates a GUI including a display image of a connection indicator indicating that it is the second console based on the setting of S20, and displays the GUI on the terminal device 2. Also good.

  8, 9, and 10 are explanatory diagrams illustrating display examples of the display unit 120 of the terminal device 2. As shown in FIG. 8, in the second console mode, the display unit 120 of the terminal device 2 has a console image G22 including a button image BT for inputting various operation instructions, and a diagnostic image such as an ultrasound image. G21 is displayed. Thereby, even when the operator is away from the apparatus main body 20 of the ultrasonic diagnostic apparatus 100, it is possible to easily check and operate the ultrasonic image and the like.

  Also, as shown in FIG. 9, when the connection indicator display is set, the connection indicator image G23 indicating the second console mode is displayed on the display unit 120 in the second console mode. Thereby, the operator can confirm easily that it is a 2nd console mode.

  In the connection indicator display in the second console mode, as shown in FIG. 10, a connection indicator image G24 including information for identifying the ultrasonic diagnostic apparatus 100 such as the name of the ultrasonic diagnostic apparatus 100 that is the connection destination is displayed. May be. Specifically, when the communication control unit 252 generates a GUI including the display image of the connection indicator, information identifying itself is read from a ROM or the like, and the sub display image G2 including the connection indicator image G24 is read. Generate. In the case where the monitor 30 performs connection indicator display including information for identifying the terminal device 2 such as the name of the terminal device 2 that is the connection destination, the display control unit 251 uses the name of the terminal device 2 that is in communication connection. And a communication address may be acquired and a main display image G1 including the acquired information may be generated.

  In the tablet use mode, since the terminal device 2 is used separately from the ultrasonic diagnostic apparatus 100 as a normal tablet, the display control unit 251 generates the main display image G1, and the communication control unit 252 The terminal device 2 is notified of the tablet use mode without generating the sub display image G2. Thereby, in the ultrasonic diagnostic apparatus 100, the main display image G1 is displayed on the monitor 30. The terminal device 2 can be used as a normal tablet separated from the ultrasonic diagnostic apparatus 100.

  FIG. 11 is an explanatory diagram for explaining a case where the terminal device 2 is brought closer to the apparatus main body 20 of the ultrasonic diagnostic apparatus 100. As shown in FIG. 11, in this embodiment, while the apparatus main body 20 and the terminal device 2 are approaching each other (for example, within a range in which the lower limb of the subject P in the examination room in which the apparatus main body 20 is installed can be inspected). The terminal device 2 operates in the second console mode. When the terminal device 2 is taken out from an examination room or the like in which the device main body 20 is installed and the device main body 20 and the terminal device 2 are moved away from each other, the terminal device 2 operates as a normal tablet. Note that the switching of the operation mode depending on the distance between the apparatus main body 20 and the terminal apparatus 2 may be reversed, and is not particularly limited to the illustrated example.

  Further, in the lower limb examination mode, the display device 251 generates the main display image G1 for the lower limb examination because the operator uses the terminal device 2 away from the apparatus main body 20 and performs the lower limb examination. The communication control unit 252 generates a sub display image G2 for displaying a GUI for inputting various operation instructions related to the lower limb examination and an image such as an ultrasonic image. Similarly, when in the abdominal examination mode, the operator uses the terminal device 2 away from the apparatus main body 20 to perform the abdominal examination, so the display control unit 251 generates the main display image G1 for abdominal examination. The communication control unit 252 generates a sub display image G2 for displaying a GUI for inputting various operation instructions related to the abdominal examination and an image such as an ultrasonic image.

  In the case of the lower limb examination, the examination is performed by bringing the ultrasonic probe 10 into contact with the lower limb of the subject P in a standing state, so that the operator places the terminal device 2 with respect to the ultrasonic diagnostic apparatus 100 at a low position near the floor surface. In this way, the terminal device 2 is used. Further, in the case of an abdominal examination, since the examination is performed by bringing the ultrasonic probe 10 into contact with the abdomen of the subject P in a state of sleeping on a bed or the like, the operator has the position of the terminal device 2 with respect to the ultrasonic diagnostic apparatus 100. The terminal device 2 is used so as to be located at a high position away from the floor surface.

  FIG. 12 is an explanatory diagram illustrating switching of operation modes at a height relative to the apparatus main body 20 of the ultrasonic diagnostic apparatus 100. As shown in FIG. 12, the vicinity of the input device 40 of the apparatus main body 20 is set as the height of the determination reference (dotted line in the figure), and the control is performed when the position of the terminal device 2 is lower than the determination reference. The unit 25 switches to the lower limb examination mode. Further, when the position of the terminal device 2 is higher than the determination criterion, the control unit 25 switches to the abdominal examination mode.

  Therefore, in the second console mode, the terminal device 2 is switched to the lower limb examination mode when the terminal device 2 is moved so that the position of the terminal device 2 is lower near the floor than the determination standard. Since switching to the abdominal examination mode is performed when the terminal device 2 is moved so that the position becomes higher, it is possible to save the labor of the switching operation to be performed by the operator.

  In the second console mode, the terminal device 2 is switched to the lower limb inspection mode when the terminal device 2 is in the vertical orientation so that the inspection target is displayed in a portrait suitable for the lower limb examination. As shown, since the terminal device 2 is switched to the abdominal examination mode when the terminal device 2 is turned sideways, it is possible to save the labor of the switching operation to be performed by the operator.

  Note that the above-described configuration and flowchart are examples, and some functions may be omitted. For example, the apparatus main body 20 may not include the cradles 261, 261a, and 261b for placing the terminal device 2. In this case, the flowchart may omit the processes of S12 to S15. Also, the lower limb examination mode and the abdominal examination mode may be provided with either one of the modes, and the processing of the flowchart may be appropriately changed according to the configuration.

  According to at least one embodiment described above, even when the operator leaves the ultrasonic diagnostic apparatus, confirmation of the ultrasonic image and operation can be easily performed.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.

  In addition to switching the operation mode according to the relative position of the terminal apparatus 2 with respect to the ultrasonic diagnostic apparatus 100, the attitude of the terminal apparatus 2, and the connection status with the cradles 261, 261a, and 261b, the ultrasonic diagnostic apparatus 100 is not limited to the above. The resolution and frame rate of the image may be changed according to the relative position, posture, and connection status.

  For example, when connected to the cradle 261a (charged), an image with high resolution and frame rate may be transferred even if power consumption is large. More specifically, when the second monitor mode is set in S15, the communication control unit 252 generates a sub display image G2 including an image to be displayed as an auxiliary to the main display image G1 with a higher resolution and frame rate than usual. It may be transferred.

  In addition, when the distance between the ultrasonic diagnostic apparatus 100 and the terminal apparatus 2 is short (during diagnosis that is directly facing the subject P, not in the second console mode), the terminal apparatus 2 is used for diagnosis, so communication control is performed. The unit 252 may generate and transfer an image having a higher resolution and frame rate than usual.
