Description

  The present invention relates to an ultrasonic diagnostic apparatus, and more particularly to an ultrasonic diagnostic apparatus having a portable apparatus main body.

  Ultrasound diagnostic apparatuses are used in the medical field. The ultrasonic diagnostic apparatus is an apparatus that transmits / receives ultrasonic waves to / from a living body and forms an ultrasonic image based on a reception signal obtained thereby. Recently, a portable ultrasonic diagnostic apparatus has been put into practical use. Such an ultrasonic diagnostic apparatus is generally composed of an apparatus main body having a display and an input device and having a built-in battery, and a probe connected to the apparatus main body. Tablet-type (including a smartphone-like shape) device body has also been put into practical use. In such a flat type device body, a display and an input device are integrated to form a display input panel. In such a device body, only a few physical switches are provided. Since the main body of the device has a thin plate shape, and substantially all or the main part of the surface constitutes the display screen, it is easy to face the main body of the device to the person observing the display screen. It is. It is expected that such an ultrasonic diagnostic apparatus will be used in home medical care, emergency medical care, hospital room medical care, and the like.

  The ultrasonic diagnostic apparatus has a function of entering a comment on an ultrasonic image, and various information is input by the inspector (examiner, doctor) using the function. For example, marking of a malignant tumor and writing of characters (unconfirmed diagnosis information, etc.) indicating the possibility may be performed. Such information should not be shown to the subject on the spot. Since the display screen is usually directed to the examiner and is in a blind spot or difficult to see from the subject, the entry information is not easily obtained by the subject.

  On the other hand, from the viewpoint of informed consent, an act of showing and explaining a diagnostic image to a subject is often performed. When the ultrasonic image includes information that the patient does not want to show to the subject as described above, it is difficult to explain while providing the subject with the ultrasonic image. There is a risk that the display screen may be inadvertently shown to the subject, or the subject may look into. If the comment is deleted when the image is shown to the subject, the trouble of re-input occurs. If the comment is entered after the image is shown to the subject, the input operation cannot be performed at the optimum timing.

  In Patent Literature 1, in an ultrasonic diagnostic apparatus, an arm sensor that supports a display is provided with an angle sensor, and based on the output, it is detected that the display screen is directed toward the subject, and the detection is performed based on the detection. A technique for hiding information that the user does not want to show is disclosed. However, it does not describe display management in a tablet ultrasonic diagnostic apparatus that does not include an arm mechanism. Patent Document 2 discloses an ultrasonic diagnostic apparatus including a display for an examinee in addition to a display for an examiner. By changing the contents of each display, providing information to the subject more than necessary is avoided.

An object of the present invention is to provide an appropriate image to each of an inspector and a subject in an ultrasonic diagnostic apparatus including a portable apparatus body having a high degree of freedom of posture change. is there. Alternatively, an object of the present invention is to prevent information inappropriate for a subject from being inadvertently provided to the subject.

  The present invention relates to an ultrasonic diagnostic apparatus having a portable apparatus main body having a display surface for displaying an image, a detector that outputs a detection signal indicating the attitude or attitude change of the apparatus main body, and an output from the detector Control means for changing the content of the image displayed on the display surface based on the detected signal.

  According to the above configuration, the apparatus main body is provided with the detector, and the information (detection signal) indicating the attitude of the apparatus main body or the attitude change is acquired by the detector, and the content of the display image is controlled based on the information. Is possible. For example, by specifying the posture or posture change of the apparatus main body, it is possible to determine whether the display surface is directed toward the examiner or the subject. That is, it becomes possible to determine the person who is observing the display surface and change the content of the display image to be suitable for that person. The detection signal can also be used for control other than display content control, for example, for image upside down control, display brightness control, in-screen layout control, and the like.

  The portable apparatus main body may be formed in a tablet shape or a flat plate shape. With such a form, the reversing operation of the apparatus main body is easy. It is desirable to perform wireless transmission between the apparatus main body and the ultrasonic transducer (probe unit). In that case, the mobility of the apparatus main body can be improved. However, a probe may be connected to the apparatus main body via a cable.

Desirably, further comprising an image forming means for generating an image and a subject image for the examiner, the control unit, the inspector image for displaying the inspector image on the display surface based on said detection signal A display mode is selected from among a display mode and a subject image display mode for displaying the subject image on the display surface. Preferably, the examiner image is an image including an ultrasound image and the inspection's information, the subject image is an image not including the test's information including the ultrasound image.

  According to the above configuration, the subject image can be displayed when the display surface is directed toward the subject, and the examiner image can be displayed when the display surface is directed toward the examiner. The latter examiner image may include, in addition to the ultrasonic image, a sentence or a comment indicating the image diagnosis result entered by the examiner. This usually includes information necessary for diagnostic imaging and information added afterwards. The latter subject image is an image shown to the subject in an aspect such as informed consent, and usually includes an ultrasound image. However, the display of information that is not desired to be shown to the subject is limited. Reference information such as an organ name and an anatomical chart may be included in the subject image. According to such a configuration, it is possible to achieve convenience in image observation of the subject.

  Preferably, the control means changes the posture of the apparatus main body from the upright posture to the inverted posture based on the detection signal and changes the posture of the apparatus main body from the inverted posture to the erect posture. The display control means selects the subject image display mode when the change in posture for the subject is determined, and the change in posture for the examiner is determined. The inspector image display mode is selected. Preferably, the posture change for the subject is a one-side rotational movement around the horizontal axis of the apparatus main body, and the posture change for the examiner is a second-side rotational movement around the horizontal axis of the apparatus main body.

  Usually, the examiner is facing the subject lying on his / her side (or is in a half body posture with respect to the subject), and in such a positional relationship, the display surface of the apparatus main body usually shows the examiner. From the direction and the subject, the back side opposite to the display surface can be seen. When it is desired to show the display surface to the subject, an operation of rotating the apparatus main body about the vertical axis or an operation of rotating the apparatus main body about the horizontal axis is performed. According to the above configuration, the display mode can be automatically switched when the latter operation is performed. If the former operation can be detected, the display mode may be automatically switched based on that, but in general, a complicated mechanism is required to do so, so the display mode is switched to the latter operation. It is desirable to interlock.

Desirably, before Symbol control means rotates by inverted the display image displayed image up and down relative to the apparatus main body wherein when moving to a subject image display mode from the inspector image display mode The display image is rotated up and down with respect to the apparatus main body at the time of transition from the subject image display mode to the inspector image display mode to erect the display image. According to this configuration, when the display mode is switched, the image can be rotated up and down together with the change of the image content. Switching from the inspector image to the inspected subject image is preferably performed before the display contents can be read from the inspecting subject as the posture of the apparatus main body is changed. The switching to the image is preferably performed after the display content becomes unreadable from the subject in accordance with the change in the posture of the apparatus main body.

  ADVANTAGE OF THE INVENTION According to this invention, in an ultrasonic diagnostic apparatus provided with the portable measure main body with a high freedom degree of posture change, a suitable image can be provided with respect to each of an examiner and a subject. Alternatively, information inappropriate for the subject can be prevented from being inadvertently provided to the subject.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows a preferred embodiment of an ultrasonic diagnostic apparatus according to the present invention, and FIG. 1 is a block diagram showing the overall configuration thereof. This ultrasonic diagnostic apparatus is used in the medical field and forms an ultrasonic image by transmitting / receiving ultrasonic waves to / from a living body.

  In FIG. 1, the ultrasonic diagnostic apparatus is roughly composed of an apparatus main body 10 and a probe unit 12. As will be described later with reference to FIG. 2, the apparatus main body 10 has a tablet-type or flat-plate form, and a portable apparatus is configured. The probe unit 12 functions as a transducer, and in this embodiment, signals are transmitted wirelessly between the probe unit 12 and the apparatus main body 10. Of course, they may be connected by a cable.

  The probe unit 12 will be described in detail. In the embodiment shown in FIG. 1, the probe unit 12 includes an array transducer 14, a transmission / reception unit 20, and a communication unit 22. Further, a battery 24 is incorporated. These configurations may be accommodated in the probe case, but may be configured by a probe head and a relay box connected thereto.

  The array transducer 14 is a 1D array transducer composed of a plurality of transducer elements. An ultrasonic beam 16 is formed by the array transducer 14, and a beam scanning surface 18 is formed by electronically scanning the beam. The beam scanning surface 18 is a two-dimensional data capturing area. As the electronic scanning method, electronic sector scanning, electronic linear scanning, and the like are known.

  The transmission / reception unit 20 is a transmission beamformer and a reception beamformer. At the time of transmission, a plurality of transmission signals are supplied from the transmission unit 20 to the array transducer 14, thereby forming a transmission beam. At the time of reception, the reflected wave from the living body is received by the array transducer 14, whereby a plurality of received signals are output from the array transducer 14 to the transmitting / receiving unit 20 in parallel. The transmission / reception unit 20 performs phasing addition processing on a plurality of reception signals, thereby outputting beam data as reception signals after phasing addition.

  The communication unit 22 is a module that performs communication with the communication unit 28 provided on the apparatus main body 10 side. In this embodiment, a wireless transmission method is employed, and signals are transmitted using radio waves, infrared rays, and the like. A control signal is transmitted from the communication unit 28 to the communication unit 22, and reception data is transmitted from the communication unit 22 to the communication unit 28. Of course, other necessary signals are also transmitted between the two communication units 22 and 28.

  Therefore, a control signal sent from the apparatus main body 10 side is sent to the transmission / reception unit 20 via the communication unit 28 and the communication unit 22, and the transmission / reception unit 20 generates a transmission signal and processes a reception signal based on the control signal. Run. A part of the functions of the reception beamformer may be provided in the probe unit 12 and the remaining functions may be provided on the apparatus main body 10 side. The battery 24 supplies power to each component in the probe unit 12.

  Next, the apparatus main body 10 will be described in detail. As described above, the communication unit 28 is a module that transmits signals to and from the communication unit 22 by a wireless method. Each beam data output from the communication unit 28 is sent to the signal processing unit 30. The signal processing unit 30 is a module that applies various types of signal processing such as detection processing and logarithmic compression processing to beam data. The image forming unit 32 is a module that forms display frame data, that is, a B-mode image (two-dimensional monochrome tomographic image) based on a plurality of beam data, that is, received frame data. The image data generated thereby is output to the display 48 of the touch panel 46 via the display processing unit 34.

  The display processing unit 34 has a function of configuring a display image, and specifically includes an image composition function, a color calculation function, and the like. The touch panel 46 described above includes a display device 48 and an input device 50. In this embodiment, the display device 48 includes a liquid crystal display, and the input device 50 includes a touch screen superimposed on the liquid crystal display. ing. Information from the input device 50 is sent to the main controller 36.

  The main controller 36 controls the operation of each component shown in FIG. Among the functions of the main control unit 36, the posture determination function is represented as a posture determination unit 38, and the display control function is represented as a display control unit 40. A signal from the attitude sensor 42 is sent to the main control unit 36. As will be described later, the posture sensor 42 includes an inclination sensor, an acceleration sensor, a gyro, and the like, and is used for detecting the posture or posture change of the apparatus main body 10. In the present embodiment, rotation angles around the X, Y, and Z axes in the main body coordinate system are detected.

  The posture determination unit 38 determines the current posture of the apparatus main body based on the output signal from the posture sensor 42. In particular, in this embodiment, as will be described later, a posture change from an upright posture to an inverted posture and a posture change from an inverted posture to an upright posture are determined.

  The display control unit 40 is a module that controls display contents based on the determination result of the posture determination unit 38. When the posture change from the upright posture to the inverted posture is determined, the image for the subject is displayed on the display 48. To be displayed. That is, the subject image display mode is selected. On the other hand, when the posture determination unit 38 determines that the posture is changed from the inverted posture to the upright posture, the display control unit 40 performs control so that the inspector image is displayed on the display 48. That is, in that case, the inspector image display mode is selected.

  As will be described later, the image for the examiner is composed of an ultrasonic image, a first graphic image, and a second graphic image. Here, the first graphic image is not only for the examiner but also for the subject. It is information that can be shown. The second graphic image is an image that is shown only to the examiner, that is, information that is not desired to be shown to the subject. These are comments and annotations entered by the inspector. For example, when marking is performed to identify a diseased part on an image or when a possible disease name is entered, such information is not intended to be shown to the subject. The information is managed as a second graphic image. The inspector image is composed of an ultrasonic image and a first graphic image, and does not include the second graphic image. In this way, by managing attributes for information other than the ultrasound image, it is possible to switch the image content by switching the display mode.

  The switch 44 shown in FIG. 1 is a power switch, and a signal from the switch 44 is given to the main controller 36. The battery 52 supplies power to each component in the apparatus main body 10. Reference numeral 53 denotes a portion realized as a software function in the present embodiment. That is, information output from the communication unit 28 is processed by software. Specifically, reference numeral 53 corresponds to a CPU and a program executed thereby. Of course, some functions may be processed by software by a dedicated processor. As described above, the main control unit 36 also performs operation control of the transmission / reception unit 20 provided on the probe unit 12 side via the communication units 28 and 22. However, a normal configuration in which the probe is connected to the apparatus main body via a cable may be employed. In this case, the transmission / reception unit 20 is provided in the apparatus main body 10. By the way, the apparatus main body whose posture is to be changed may be substantially composed of only the touch panel 46 or the display 48. In other words, it is desirable to determine a change in posture of at least a part including the display and switch display contents displayed on the display.

  In FIG. 1, a Doppler information processing unit and the like are not shown. Another configuration provided in a general ultrasonic diagnostic apparatus may be included in the apparatus main body 10.

  FIG. 2 is a perspective view of the apparatus main body 10 shown in FIG. In the present embodiment, the apparatus main body 10 has a tablet shape, which includes a touch panel 46 constituting a display surface. A display screen is displayed on the touch panel 46, which includes an ultrasonic image 48. Further, the display image has an input unit 50, and a virtual keyboard and a handwriting input unit 52 are provided on the input unit 50, for example. The virtual input unit is composed of a plurality of key icons, and an arbitrary character can be input by touching each icon. Moreover, it is possible to perform handwriting input with a touch pen using the handwriting input unit 52. Such a function can be used to add comments and annotations on or near the ultrasound image 48, and such information is indicated by reference numeral 54. Specifically, reference numeral 54 indicates diagnostic information. The diagnosis information 54 is necessary information for the examiner, but is not necessarily information that is not desired to be shown to the examinee. Therefore, in the present embodiment, the display and non-display of such diagnostic information 54 are selectively switched by determining the posture of the apparatus main body 10.

  FIG. 3 shows the configuration of the display image 62. In the present embodiment, the display image 62 is configured as an image obtained by combining the first plane 56, the second plane 58, and the third plane 60. The first plane 56 is a plane including an ultrasonic image, the second plane 58 is a plane including a first graphic image that may be shown to both the examiner and the subject, and the third plane 60 is The plane including the second graphic image to be displayed only to the examiner.

  Therefore, the examiner image is configured as an image obtained by synthesizing three images from the first plane 56 to the third plane 60, while the image for the examinee is composed of only the first plane 56 and the second plane 58. The image is configured as an image that does not include the third plane 60.

  FIG. 4 shows an absolute coordinate system and a coordinate system defined on the apparatus main body 10. The absolute coordinate system is determined based on gravity or the vertical direction, and is composed of orthogonal X, Y, and Z axes. The Z axis faces the vertical direction. The X axis and the Y axis are horizontal axes. On the other hand, the x axis, the y axis, and the z axis are defined as the movable coordinate system on the apparatus main body 10. They pass through the detection origin of the sensor 42, where the z-axis corresponds to the major axis of the apparatus body 10, the x-axis corresponds to the minor axis of the apparatus body 10, and they are vertically and horizontally on the display surface. It corresponds. The y-axis corresponds to the normal line of the display surface, that is, the axis orthogonal to the display surface.

  In the present embodiment, the sensor 42 detects the rotation angle about the X axis, the rotation angle about the Y axis, and the rotation angle about the Z axis for the apparatus main body 10. Incidentally, there is a function of rotating the image 90 degrees so that the display image stands upright regardless of whether the display surface is oriented vertically or horizontally. In addition, as described later, a function for determining a change from an upright posture to an inverted posture and a change from an inverted posture to an upright posture is installed.

  FIG. 5 conceptually shows the posture change from the upright posture to the inverted posture. In FIG. 5, S1 indicates an upright posture. Even if it is said to be an erect posture, here it is a tilted posture with the display surface 64A directed obliquely upward. This is defined as an upright posture. As indicated by reference numeral 100, the display surface 64 </ b> A is observed by the examiner with a line of sight obliquely below. Further, as indicated by reference numeral 102, an input is performed by the examiner's finger or touch pen in such an upright posture. Of course, the upright posture may be a completely vertical posture, or may be a posture in which the display surface 64A is more upward.

  From such an upright posture, the posture change is started as indicated by S2. Specifically, the posture is changed so that the apparatus main body 10A rotates around the horizontal axis while the back surface of the apparatus main body 10A faces downward. In FIG. 5, the rotation angle of the z axis with respect to the Z axis, which is the vertical axis, is shown.

  In the middle of such a posture change, as shown in S6, image rotation and display mode change are executed. The rotation of the image is to invert the displayed image up and down, that is, to rotate 180 degrees. The display mode change means a change from the examiner image display mode to the subject image display mode. S4 indicates an inverted posture. The inverted posture is a state in which the apparatus main body 10B is inclined while the display surface 64B is directed obliquely upward. Of course, the display surface 64B may be more upward, or the apparatus main body 10B may be in a completely vertical state. In the upright posture, the sensor 42A is located at the upper part as viewed from the apparatus main body 10A, but in the inverted posture, the sensor 42B is located at the lower part as seen from the apparatus main body 10B. Reference numeral 104 indicates an observation direction of the display surface 64B in the apparatus main body 10B in the inverted posture. That is, the subject is observed from obliquely above.

  As described above, when there is a posture change from the upright posture to the inverted posture, the posture change is determined in the middle, and the display mode is changed based on the determination. At the same time, image rotation is executed. The image for the examiner is displayed in the upright posture, but the image for the subject can be displayed in the inverted posture by changing the display mode. That is, it is possible to hide information that is not desired to be shown to the subject.

  Incidentally, the determination of the posture change from the upright posture to the inverted posture may be performed, for example, when the rotation angle of the z axis with respect to the Z axis becomes a constant angle. Incidentally, when the apparatus main body 10A is in the laid-down state in the upright posture, when determining the posture change from there, the rotation angle of the x axis relative to the Z axis may be used as a judgment criterion.

  FIG. 6 conceptually shows the posture change from the inverted posture to the upright posture. In the inverted posture shown in S4, the apparatus main body 10B has its display surface 64B directed toward the subject, that is, an inclined posture. Then, when the apparatus main body 10B rotates in the other direction around the horizontal axis while the back surface of the apparatus main body 10B is directed downward, the upright posture shown in S7 is obtained. S5 represents the start of posture change, and image rotation and display mode change are executed as indicated by S6 during the posture change from there. In other words, when the posture change from the inverted posture to the upright posture is determined, the displayed image is flipped up and down, and at the same time, the change from the subject image display mode to the examiner image display mode is performed. Executed. As a result, the display content is returned to the normal content. Reference numeral 10C denotes the apparatus main body in the upright posture, and reference numeral 64C denotes the display surface in the upright posture. The sensor 42C is again positioned above the apparatus main body 10C.

  FIG. 7 shows a posture change from vertical to horizontal. Reference numeral 10D denotes the apparatus main body in an inverted state, in which the sensor 42D is positioned at the lower part as viewed from the apparatus main body 10D. The display surface 64D faces obliquely upward. The normal line of the display surface 64D is the y-axis. As described above, the z-axis that is the long axis of the apparatus main body 10D is directed obliquely downward, that is, the apparatus main body 10D has a vertical posture.

  From this state, when the apparatus main body 10D is rotated around the y-axis, that is, when the posture is changed from vertical to horizontal as shown in S8, the apparatus main body 10 assumes a horizontal posture as indicated by reference numeral 10E. In this case, the x axis, that is, the short axis is an oblique direction, and the long axis coincides with the horizontal axis. The display surface 64E faces obliquely upward as before the posture change.

  In the present embodiment, the display mode is maintained even when the posture is changed from vertical to horizontal or from horizontal to vertical. That is, in the state where the subject image is displayed, even if a rotational movement about the y-axis occurs, the image content itself is not changed. However, a process of rotating the image by 90 degrees is performed in accordance with the posture change. When the posture is changed between vertical and horizontal, as shown in S9, the reference posture for determining the posture change between the upright posture and the inverted posture is updated. In the example shown in the drawing, the horizontal orientation is the reference orientation, that is, the x-axis is recognized as the reference axis for determination, and the display mode is switched based on the angle between the x-axis and the Z-axis. .

  FIG. 8 is a flowchart showing the operation of the apparatus shown in FIG. FIG. 8 shows the contents of the display control accompanying the posture change.

  In S10, initial registration of the reference posture is performed. That is, it is distinguished whether the apparatus main body is in a vertical posture or a horizontal posture. When in the vertical posture, the z-axis is selected as the reference axis for determination, and when in the horizontal posture, the x-axis is selected as the reference axis for determination.

  In S12, it is determined whether or not there has been a rotation of the apparatus body that requires display control, that is, a change in posture. Here, it is determined whether any rotation about the horizontal axis or rotation about the normal axis of the display surface has occurred. As shown in FIGS. 5 and 6, when a rotational movement around the horizontal axis occurs with the back of the apparatus main body facing downward, the display mode is changed in S14. That is, either the change from the examiner image display mode to the examinee image display mode or the change to the examinee image display mode or the examiner image display mode is executed. At the same time, in S16, processing for inverting the image up and down is executed. In S18, the reference posture is updated. For example, when the apparatus main body is rotated around the normal line of the display surface after changing from the upright posture to the inverted posture, the reference posture is updated in S18. Until the end is determined in S24, each configuration after S12 is repeatedly executed.

  In S12, when it is determined that a rotational movement around the normal line of the display surface has been performed, that is, when a rotation of 45 degrees or more is performed, a process of rotating the image by 90 degrees is performed in S20. That is, as the display surface rotates, the image is rotated so that the user can easily see the image. In S22, the reference posture is updated. As described above, even if the rotational movement about the normal axis is performed, the display mode is not changed, and such a change is performed only when the rotational movement about the horizontal axis occurs.

  In the above operation example, since the reference posture is updated, that is, whether the apparatus main body is in the horizontal direction or the vertical direction, it is possible to accurately determine the posture change from there. By the way, if the display surface is completely upward or close to it, it is difficult to determine either the upright position or the inverted position. Display may be prioritized. Or you may comprise so that the content of the display operation in such a special state can be preset in a user.

  In the above embodiment, the content of the display image is switched based on the attitude of the apparatus main body. However, other controls such as trajectory adjustment may be performed based on the attitude of the apparatus main body. In any case, the orientation of the display surface of the orbital tablet-type device body 10 can be easily changed, and it is particularly desirable to apply the above configuration in such a case.
