Description

  The present invention relates to an ultrasonic diagnostic apparatus, an X-ray CT apparatus, and a display control program having a measurement forgetting prevention function.

  Usually, an instruction input related to measurement by the ultrasonic diagnostic apparatus is executed via a TCS (Touch Command Screen). This TCS displays a list of items to be measured. An examiner such as a doctor can input an instruction to the apparatus by touching a screen position on which a desired measurement item is displayed. In recent years, this TSC has been adopted in X-ray CT apparatuses because it can be used to complete a desired input only by touching the screen and each measurement item is displayed in a list.

  In normal TCS, in order to prevent measurement omission, measurement items are displayed in a fixed area of the TCS monitor, and measurement values and calculation values are displayed in a measurement window corresponding to the positions of the measurement items of the TCS monitor. The inspector confirms the execution of the measurement based on the presence / absence of the display of the measured value and the calculated value on the screen, thereby preventing measurement omission.

  However, the above-mentioned measurement forgetting prevention function has the following problems.

  First, since it is necessary to display so as not to interfere with the image and the measurement marker, the measurement window is displayed in a limited space of the monitor. For this reason, in order to confirm the missing of the measurement item and the measured value, high attention is required, and the confirmation work also takes time.

  Second, similar names are displayed in narrow spaces. Therefore, it is easy to be mistaken, and there is a possibility that the measurement may be forgotten due to the operator's thought such as the end of the measurement.

This is an ultrasonic diagnostic apparatus.

  According to a ninth aspect of the present invention, there is provided a selection unit for selecting any one of a plurality of shooting modes, and a plurality of shooting items associated with the shooting mode selected by the selection unit. Measurement is performed by the display unit that displays the plurality of first switches in the first form, the measurement unit that performs the measurement corresponding to the photographing item selected through the display unit, and the measurement unit An X-ray comprising: display control means for changing a display form of the first switch corresponding to the photographed item to a second form different from the first form.

In the following description, components having substantially the same function and configuration are denoted by the same reference numerals, and redundant description will be given only when necessary.

(First embodiment)
In the first embodiment, a case where the technical idea according to the present invention is applied to an ultrasonic diagnostic apparatus will be described.

  FIG. 1 shows a block diagram of an ultrasonic diagnostic apparatus 10 according to the first embodiment.

  First, the block configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described with reference to FIG.

  In FIG. 1, an ultrasonic diagnostic imaging apparatus 10 includes an ultrasonic probe 11, a transmission / reception circuit (T / R) 12, a signal processing unit 15, a DSC (digital scan converter) 17, a monitor 19, a host system 21, and an FDD. (Floppy disk drive) 23, HDD (hard disk drive) 25, TCS (Touch Command Screen) 27, and input device 29.

  The ultrasonic probe 11 is a probe (probe) for irradiating a subject (patient) with imaging ultrasonic waves and receiving a reflected wave from the subject, and is formed of a piezoelectric element or the like. Has been.

  The transmission / reception circuit (T / R) 12 scans the inside of the subject with ultrasound according to a procedure corresponding to an arbitrary imaging mode such as a B mode representing a tissue structure or a Doppler mode suitable for representing blood flow information. Therefore, it is connected to the ultrasonic probe 11.

  The transmission / reception circuit (T / R) 12 amplifies the echo signal obtained by scanning for each channel and performs A / D conversion. The echo signal after A / D conversion is given a delay time necessary to determine the reception directivity, and is added to enhance the reflection component from the direction corresponding to the reception directivity. A comprehensive ultrasonic beam for transmission and reception is formed by this transmission directivity and reception directivity.

It has a function of generating image data such as B mode.

  The signal processing unit 15 performs logarithmic amplification, envelope detection processing, and the like on the echo signal from the transmission / reception circuit (T / R) 12 to generate data in which the signal intensity is expressed by brightness. Further, the signal processing unit 15 performs frequency analysis on the speed information from the echo signal and sends the analysis result to the DSC circuit 17.

  The DSC circuit 17 writes the image signal from the transmission / reception circuit (T / R) 12 into the image memory, performs TV scan conversion, and sends it to the monitor 19. Further, the DSC circuit 17 has a function of performing image processing on the image data from the transmission / reception circuit 12 in accordance with set observation conditions (for example, brightness, zoom, etc.).

  The monitor 19 is a monitor composed of a CRT or the like, and displays a tomographic image representing the shape of the subject tissue based on the input video signal.

  The host system 21 has a function as an information processing apparatus (computer) and is a control unit that controls the operation of the ultrasonic diagnostic apparatus main body 10. In the host system 21, a measurement misidentification prevention system described later is deployed.

  An HDD (Hard Disc Drive) 25 is a storage device that stores arbitrary ultrasonic image data in accordance with an operator's freeze operation or the like. The HDD 25 also displays a plurality of display patterns of measurement items in the TCS 27 recorded on the HD, messages such as names of measurement items to be applied to the display patterns, font data related to the display of the TCS 27, measurement items displayed on the TCS 27, A table or the like that associates specific operation control of the sonic diagnostic apparatus 10 is read from the HD and stored in the main storage device.

  The FDD 23 is a driver that reads data recorded in an attached auxiliary storage device (floppy disk). A part of the data stored in the HDD 25 may be stored in the FDD 23.

  The TCS 27 is a touch panel for an operator to select and instruct execution of measurement items to be executed in ultrasonic diagnosis. The TCS 27 displays a list of switches corresponding to measurement items that can be measured. The operator can input an execution instruction for the measurement by touching a switch of a desired measurement item. Further, the TCS 27 displays measurement items in a predetermined form based on control by a measurement misidentification prevention system described later.

  The input device 29 is an input means for capturing various instructions, commands, and information from the operator, and includes, for example, a keyboard 291, a mouse 292, a trackball 293, and the like.

  Next, a measurement misidentification prevention system that is one of the features of the present invention will be described. This measurement misidentification prevention system is a system that controls the display form of measurement items of the TCS 276 and is deployed in the host system 21.

  FIG. 2 is a diagram showing a schematic configuration of a measurement misidentification prevention system. The schematic configuration of the present system will be described with reference to FIG.

  The measurement misidentification prevention system includes an application program storage unit 210, a shared memory 213, a CPU 214, a C-RAM 215, a font data storage unit 251 stored in the HD 250, and an HD 250 or FDD 230. The pattern table storage unit 251, the switch table storage unit 252, and the message table storage unit 253 are configured. Hereinafter, each component will be described.

  The font data storage unit 251 stores font data for various languages (for example, Japanese, English, German, etc.) related to items displayed on the TCS 27.

  The pattern table storage unit 251 stores a plurality of switch pattern tables that are displayed in an initial state (a state in which each measurement is not performed). For example, when a diagnostic protocol is determined by inputting predetermined information such as a patient ID, a switch pattern table corresponding to the protocol is read from the pattern table storage unit 251, and a switch pattern according to the table is TCS27. Is displayed.

  The switch table storage unit 252 stores a table for associating which function of the ultrasonic diagnostic apparatus each switch constituting each switch pattern table corresponds to. The CPU 214 performs the measurement indicated by the selected switch by referring to the table.

  The message table storage unit 253 stores name data of each switch constituting the switch pattern table.

  The application program storage unit 210 stores various application programs. This measurement misidentification prevention system is executed based on a panel control program stored in the panel control I / F library 211 in the storage unit 210.

  The shared memory 213 is a main storage device that temporarily stores a program necessary for driving the system or various data to be used and transfers it to the CPU as needed. Specifically, the panel control program read from the application program storage unit 210, various information read from the pattern table storage unit 251 in the HD or FD, or the measurement history in the currently executed diagnosis, etc. Memorize temporarily.

  The CPU 214 controls the display of the TCS 27 by executing the panel control program according to a predetermined task control block.

  The RAM 215 is a storage unit that temporarily stores display data to be displayed on the TCS 27. The contents of the RAM 215 are rewritten as needed by the CPU 214 as the measurement is executed. The rewritten content is displayed on the TCS 27.

  Next, measurement item display in ultrasonic diagnosis realized by the measurement misidentification prevention system configured as described above will be described.

  FIG. 3 is a diagram showing each measurement item that can be performed in the ultrasonic diagnosis related to the cardiac function, and switches that are displayed in the measurement menu when each measurement item is selected. In the present embodiment, details of individual measurement contents are omitted, and E wave and A wave measurement (measurement in which [E] and [A] are selected in FIG. 3) is performed in MITRAL (mitral valve function measurement). An example of execution will be described.

  Here, the E wave is an inflow waveform observed by the Doppler method in the early stage of ventricular expansion. On the other hand, the A wave is an inflow waveform observed by the Doppler method in the atrial systole. By calculating the blood flow velocity, time information (eg, duration, acceleration time, deceleration time, isovolume expansion time, etc.), blood flow acceleration, blood flow deceleration, etc. It is possible to evaluate ventricular dilatability.

  4A shows the mitral valve blood flow waveform of a healthy young person, and FIG. 4B shows the mitral valve blood flow waveform of a hypertensive patient. Looking at the A wave and E wave of each patient, as shown in FIG. 4 (a), the E wave is higher than the A wave in healthy young people, whereas in the hypertensive patient, the A wave is reversed and the E wave is higher than the E wave. You can see that it is getting higher. It can be recognized that the relaxation of the left ventricle is delayed from the decrease in the E wave of this hypertensive patient and that the compensatory contraction is increased from the increase in the A wave.

  Next, display of the TCS 27 for preventing measurement misidentification, which is executed in E wave and A wave measurement, will be described.

  FIG. 5 shows an example of a screen that is first displayed on the TCS 27 in the ultrasonic diagnosis related to the cardiac function. In the figure, all switches are displayed in the same shape, reflecting that no measurement relating to ultrasonic diagnosis is currently performed. Such a display state is hereinafter referred to as an “initial state”.

  An inspector such as a doctor or an examination engineer first presses a “MITRAL” (mitral valve function measurement) switch displayed on the TCS 27. In response to this operation, the CPU 214 reversely displays the “MITRAL” switch. By this reverse display, the inspector can easily know that the currently executed measurement is “MITRAL”. As shown in FIG. 5, a measurement menu “MITRAL” is displayed on the left half of the screen together with the reverse display.

  Subsequently, the inspector touches the “E” switch displayed on the TCS 27. In response to this operation, the CPU 214 highlights the “E” switch and starts E wave measurement. Note that the reverse display of the “E” switch is continuously executed during the measurement operation of the E wave.

  When the E wave measurement ends, the CPU 214 writes the fact that the E wave measurement has ended in the shared memory 213 as “current patient measurement history”. Further, the CPU 214 rewrites information on the “E” switch on the RAM 21 and changes the display form to a display form indicating the end of measurement as shown in FIG. Similarly, the A wave is measured, and when the measurement of the A wave ends, the CPU 214 changes the “A” switch to the display form shown in FIG. 8 along with the end of the measurement.

  This change in the display form accompanying the end of measurement is one of the features of the ultrasonic diagnostic apparatus 10. The inspector can visually quickly determine that the E wave measurement has already been completed in the MITTAL measurement by the change in the display form. For example, unlike the present embodiment, it is assumed that the end of measurement is not reflected in the display form of the switch (that is, the conventional display form). In this case, the screen display of the TCS 27 at the end of the A wave measurement is, for example, as shown in FIG. Therefore, for example, if the inspector forgets whether or not E-wave measurement has been performed, it is necessary to confirm the measured value displayed on the monitor 19 or to output a report again to confirm. Can not do it. As a result, more time may be required for measurement.

  On the other hand, according to the ultrasonic diagnostic apparatus 10, each switch is displayed in a form reflecting the end of measurement, as shown in FIG. Can be grasped. As a result, the fact that the measurement has been completed can be accurately grasped without misunderstanding.

  In addition, since this embodiment has shown the example which performs E wave measurement and A wave measurement as MITRAL, with the completion | finish of A wave measurement, a "MITRAL" switch also changes to the display form reflecting the completion | finish of measurement. (See, for example, FIG. 9).

  Subsequently, when shifting to “PULMO VEIN” (pulmonary vein function measurement), the “PULMO VEIN” switch displayed on the cardiac function menu screen of the TCS 27 is selected. In response to this switch selection, the CPU 214 reversely displays “PULMO VEIN”, and displays the switch pattern corresponding to the “PULMO VEIN” measurement, the names of executable measurement items displayed on each switch, and the like corresponding to HD or FD. Read from each storage unit.

  FIG. 9 shows an example of a screen displayed on the TCS 27 when “PULMO VEIN” (pulmonary vein function measurement) is selected. The display control / form in the case of performing the measurement “S1”, “S2”, “D” regarding the pulmonary vein function measurement will be described with reference to FIG.

  When the “S1” switch displayed on the TCS 27 is selected by the inspector, the CPU 214 highlights the “S1” switch and starts measurement. The reverse display of the “S1” switch is continuously executed during the S1 measurement operation.

  When the S1 measurement ends, the CPU 214 writes the fact of the end of the S1 measurement in the shared memory 213 as “current patient measurement history”. Further, the CPU 214 rewrites information on the “S1” switch on the RAM 21 and changes the display form to a display form indicating the end of measurement as shown in FIG. Similarly, S2 measurement and D measurement are sequentially selected and executed. The CPU 214 changes each switch to a display form whenever each measurement is completed. At the stage where each measurement is completed, the TCS 27 displays the screen shown in FIG.

  In order to confirm whether or not the E-wave measurement and A-wave measurement of “MITRAL” have been properly executed from the screen state of FIG. 10B, the “MITRAL” switch on the cardiac function menu screen is pressed. As a result, a measurement item menu screen corresponding to “MITRAL” is displayed as shown in FIG. According to the screen, the switches corresponding to the measurement items “E” and “A” already performed are displayed in a form reflecting the end of the measurement. Therefore, the inspector can check the completed inspection item at an arbitrary timing. As a result, the work load on the inspector can be reduced, and misperception in the work can be prevented.

  On the other hand, according to the conventional ultrasonic diagnostic apparatus, when the “MITRAL” switch on the cardiac function menu screen is pressed in the screen state of FIG. 10B, a screen similar to the initial state shown in FIG. Is displayed. Therefore, in the conventional ultrasonic diagnostic apparatus, the fact of the measurement execution cannot be confirmed by the TCS 27, and it is necessary to confirm the measurement value separately displayed on the monitor 19.

  The display form reflecting the end of measurement may be any form as long as the end of measurement can be grasped. For example, the switch may be changed to a shape different from the example shown in FIGS. 7 to 10 before and after the execution of measurement, or the color, size, etc. may be changed. In addition, the executed measurement item name may be deleted with a double line.

  Further, the display form reflecting the end of measurement is maintained until the inspector performs a predetermined input instructing the reset. Therefore, while continuing the predetermined ultrasonic diagnosis work, the history of measurement in this diagnosis can be easily grasped unless the input is performed. Further, the display form reflecting the end of measurement may be automatically reset and displayed at the timing when the examinee changes. The automatic grasping of the replacement timing can be realized by inputting the ID of a new patient (inspector).

  Next, a modification of the present embodiment will be described with reference to the drawings.

  For example, in ultrasonic diagnosis, the same measurement may be repeated a plurality of times to obtain an average of measured values. For example, in each measurement of the A wave and the E wave described above, an average spectrum obtained from several measurements may be used for ultrasonic diagnosis. The modification described below is particularly advantageous when the same measurement item is executed a plurality of times for the same patient.

  FIG. 12 is a diagram for explaining a modification of the first embodiment. In other words, in the above-described content, a display capable of discriminating before and after the measurement execution is performed in the form shown in FIG. On the other hand, as shown in FIG. 12B, a configuration may be adopted in which the number of executions can be determined. For example, in FIG. 12B, a mark (in the figure, a check) is added every time the measurement is executed. The inspector can grasp the number of executions of the measurement by counting the number of marks.

  The display form according to this modification is not limited to the above example, and any display form can be used as long as the number of executions can be grasped. For example, in addition to the above example, the number of executions may be displayed as a number representing the number of executions or a symbolic figure representing the number of executions (for example, “positive”).

  In addition, the switch reflecting the shape of the switch and the number of measurement changes before and after the measurement execution is automatically reset every time the subject (patient) is changed, for example, according to the input of the patient ID. It is preferably reset automatically. This configuration is realized by the CPU 214 resetting the current measurement history and resetting the TCS27 display to the initial state in response to the patient ID input from the KB 291 or the like, or restarting the measurement misidentification prevention system. Is possible. With this configuration, the examiner does not need to manually perform reset control of the TCS 27 every time the examinee (patient) is switched, and improvement in workability can be expected.

  According to the configuration described above, the inspector can visually check whether each measurement has been executed, or determine the number of times each measurement has been executed, according to the display form of the cardiac function switch or each measurement item switch displayed on the TCS 27. Visual confirmation can be done easily and quickly. Therefore, the inspector can accurately perform the measurement work without any misunderstanding of the measurement already performed and the measurement not yet performed.

By this reverse display, the inspector can easily know that the form of imaging currently being executed is “helical 2 mm / 2 mm”.

  When the imaging by the 2 mm / 2 mm helical scan is completed, the CPU 534 writes the fact that the imaging by the 2 mm / 2 mm helical scan has ended in the shared memory 533 as the “current patient imaging history”. Further, the CPU 534 rewrites information on the “helical 2 mm / 2 mm” switch on the RAM 535 and changes the display form to a display form indicating the end of photographing as shown in FIG. 17, for example.

  When shooting is continued, display related to the switch corresponding to the shooting mode executed in the same manner is controlled.

  According to the configuration described above, the inspector or the like can visually check whether or not each shooting has been performed, or visually check the number of times each shooting has been performed, depending on the display mode of the shooting mode item switch displayed on the TCS 60. Can be performed easily and quickly. Therefore, the inspector can perform the photographing operation accurately and safely without misidentifying the photographing that has already been performed and the photographing that has not yet been performed.
