Description

  The present invention relates to a technique for registering a character string for annotation display.

  For diagnosis of a subject, an image diagnostic apparatus that captures an image of the subject and creates a tomographic image thereof is used. For example, an ultrasonic diagnostic apparatus, an X-ray CT apparatus, an MRI apparatus, a nuclear medicine diagnostic apparatus, and the like. The created tomogram is displayed on the monitor and used for diagnosis of the subject.

  In recent years, an annotation display function is often added to this diagnostic imaging apparatus (see, for example, “Patent Document 1”). The annotation display function displays a character string such as an annotation called an annotation or a comment on the tomographic image of the monitor during inspection.

  The operator calls a character string registered in advance in the image diagnostic apparatus or operates the input means provided in the image diagnostic apparatus to input the character string and display the annotation. The registered character strings are separately registered by operating the input means by the operator himself in addition to those prepared from the beginning.

  The registration procedure requires an operation of displaying a registration screen on the monitor of the ultrasonic diagnostic apparatus, inputting a character string to be registered on the registration screen, and assigning the character string to a predetermined key. Due to the complexity of this registration procedure, it is troublesome for an operator to register a character string, and even a character string that is frequently used is often operated by key operation on the spot.

  Hereinafter, a preferred embodiment of an annotation display device according to the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of an ultrasonic diagnostic apparatus having an annotation display apparatus according to the present embodiment. The ultrasonic diagnostic apparatus 100 is an apparatus for inspecting a subject by transmitting ultrasonic waves to the subject and creating and displaying a tomographic image in the subject from the received ultrasonic waves. During the inspection, the created tomographic image is displayed, and annotations (character strings such as annotations and comments) input by the operator are overlaid on the tomographic image.

  In the annotation display, a character string (registered character string) registered in advance in the ultrasonic diagnostic apparatus 100 is called and displayed, or a character string (input character string) input with a keyboard is displayed. Registration refers to a state in which a character string is stored and the character string is assigned to a button. Registered character strings include pre-prepared character strings, input character strings that are input more than a predetermined number of times during inspection, and input character strings that are selected from a list of input character strings that are input during inspection. be registered. Examples of registered character strings include character strings such as MR (mitral regurgitation), MS (mitral stenosis), and ASD (atrial septal defect).

  The ultrasonic diagnostic apparatus 100 includes an ultrasonic probe 101, a transmission / reception unit 102 connected to the ultrasonic probe 101, a signal processing unit 103 connected to the transmission / reception unit 102, and image processing connected to the signal processing unit 103. The tomographic image of the subject is created from ultrasonic waves. The monitor 106 is configured to display the created tomogram and annotation.

  Further, the control unit 107 is configured to control the transmission / reception unit 102, the signal processing unit 103, the image processing unit 105, and the monitor 106 so as to create a tomographic image from the ultrasonic wave, or display it on the monitor 106, or display an annotation. Is running. The control unit 107 executes control by using a command input using the operation panel 109 or completion of a predetermined operation as a trigger.

  The ultrasonic probe 101 transmits and receives ultrasonic waves into the subject. The ultrasonic probe 101 includes a piezoelectric body and an electrode pair disposed with the piezoelectric body interposed therebetween. The piezoelectric body is an acoustic / electric reversible conversion element made of a piezoelectric ceramic such as lead titanate. A voltage is applied from the electrode pair to the piezoelectric body to generate a piezoelectric effect, and an ultrasonic wave is transmitted in a direction orthogonal to the electrode pair. On the other hand, the piezoelectric body receives ultrasonic waves to produce a piezoelectric effect, converts the received ultrasonic waves into an echo signal having a voltage value corresponding to the intensity, and flows to the electrode pair.

  The voltage applied to the ultrasonic probe 101 is supplied from the transmission / reception unit 102. The transmission / reception unit 102 includes a transmission unit and a reception unit. Both the transmitter and the receiver are connected to the electrode pair. The transmission unit applies a predetermined voltage to the electrode pair of the ultrasonic probe 101. The receiving unit receives an echo signal transmitted from the electrode pair.

  The echo signal is output from the receiving unit to the signal processing unit 103. The signal processing unit 103 performs signal processing for generating a two-dimensional tomographic image on the echo signal or performs signal processing for generating a two-dimensional blood flow image to obtain respective raster image data. In signal processing for two-dimensional tomographic image generation, the echo signal is subjected to bandpass filter processing, the envelope is then detected, and the detected data is subjected to compression processing by logarithmic transformation, thereby rasterizing the two-dimensional tomographic image. Obtain image data. In 2D blood flow image generation signal processing, the phase is detected, high-pass filter processing (MTI filter processing) that separates tissue signals and blood flow signals is performed, and autocorrelation processing is performed, so that the blood flow velocity Raster image data of blood flow information such as dispersion, power, etc. is obtained.

  The raster image data is output from the signal processing unit 103 to the image memory 104. The image memory 104 temporarily stores the output raster image data.

  The raster image data stored in the image memory 104 is read out to the image processing unit 105. The image processing unit 105 converts the raster image data into a video format of an orthogonal coordinate system (scan conversion process).

  The image data converted into the video format is output to the monitor 106. The monitor 106 displays image data of a two-dimensional tomographic image. When image data of a two-dimensional blood flow image is generated together, it is displayed superimposed.

  The control unit 107 controls from transmission / reception of ultrasonic waves to generation and display of image data. The control unit 107 includes a sequencer 108. The sequencer 108 outputs a control signal to the transmission / reception unit 102, the signal processing unit 103, and the image processing unit 105, and causes each process corresponding to the control signal to be executed. The control signal generation of the sequencer 108 is performed according to control commands and control data generated by a computer composed of a CPU (arithmetic control device) 107a, a RAM (main storage device) 107b, and an HDD (external storage device) 107c.

  The HDD 107c is a non-volatile memory, and stores an OS (Operating System), a program for generating control commands and control data, and a program for realizing various functions. A program is appropriately read out from the HDD 107c, loaded into the RAM 107b, and the CPU 107a decodes and executes the loaded program, so that a control command and control data are output to the sequencer 108.

  A program corresponding to a command input using the operation panel 109 is read from the HDD 107c. The operation panel 109 is a liquid crystal touch panel that detects coordinates instructed by a coordinate reading principle such as an electromagnetic induction type, a magnetostriction type, or a pressure sensitive type, and displays operation keys as a soft keyboard.

  FIG. 2 is a diagram showing the console 110 during the examination of the ultrasonic diagnostic apparatus 100. As shown in FIG. 2, a monitor 106 and an operation panel 109 are embedded in the console 110.

  A two-dimensional tomographic image and a two-dimensional blood flow image are displayed on the monitor 106. A soft keyboard is displayed on the operation panel 109. The soft keyboard is provided with input keys 113 for character characters such as character keys and numeric keys, and operation keys such as keys associated with various functions. Registered character string display keys 112a, 112b, 112c, 112d, 112e, 112f,... For displaying the registered character strings on the monitor 106 as annotations are arranged on the keys associated with the various functions. A predetermined registered character string is assigned to the registered character string display key 112a. By pressing either the input key 113 or the registered character string display key 112a..., The character or character string assigned to the pressed key is displayed on the image displayed on the monitor 106.

  FIG. 3 is a block diagram showing a configuration mainly using annotation display. As shown in FIG. 3, the annotation display and the image display are triggered by command input from the operation panel 109 or completion of a predetermined operation as a trigger, and the annotation display program and data and the image display program stored in the HDD 107c are expanded in the RAM 107b. This is realized by the CPU 107a decoding and executing, and controlling the monitor 106, HDD 107c, and RAM 107b according to the result.

  In the image display, the CPU 107a functions as the medical image display control unit 10 by inputting an image display command using the operation panel 109. The medical image display control unit 10 causes the image processing unit 105 to convert the raster image data stored in the image memory 104 into a video format and display it on the monitor 106.

  In the annotation display, the CPU 107a functions as the key display control unit 11 by inputting an image display command using the operation panel 109, and functions as the annotation unit 13 by pressing a special function key or inputting a character string using the operation panel 109. It functions as the registration unit 15 when the examination by the ultrasonic diagnostic apparatus 100 is completed.

  The key display control unit 11 causes the operation panel 109 to display input keys 113 such as character keys and numeric keys, and registered character string display keys 112a. A registered character string (registered character string) is assigned to the registered character string display key 112a. The registered character string to be assigned is acquired from the registered character string storage unit 12.

  FIG. 4 is a diagram illustrating the registered character string storage unit 12. The registered character string storage unit 12 is a storage area configured by the HDD 107c which is a nonvolatile memory. As shown in FIG. 4, the registered character string storage unit 12 stores a plurality of registered character strings. The storage destination address of each registered character string is managed by an index, and each registered character string display key 112a... Is associated with the registered character string via this storage destination address.

  The annotation unit 13 displays the character string on the monitor 106. In response to the input of the registered character string display key 112a..., The registered character string assigned to the registered character string display key 112a... Is acquired from the registered character string storage unit 12 and displayed on the monitor 106. Corresponding to the input of the character key or numeric key, the character assigned to the input character key or numeric key is displayed on the monitor 106. When one or more character keys or numeric keys are input continuously, a character string (input character string) arranged in the input order is displayed on the monitor 106.

  When a character string is input using a character key or a numeric key, the annotation unit 13 sequentially stores the input character string corresponding to the input in the input character string storage unit 14 regardless of duplication.

  Further, the input character string is compared with the registered character string stored in the registered character string storage unit 12, and when the input character string is already registered, the input character string is registered in the monitor 106. A pop-up window in which a message notifying that is described is displayed.

  FIG. 5 is a diagram showing the input character string storage unit 14. The input character string storage unit 14 is a storage area configured by a RAM 107b, which is a volatile memory that maintains stored contents by current. The input character string storage unit 14 sequentially stores the input character strings input with the character keys or numeric keys in the empty area. If an input character string composed of the same character string is input a plurality of times, the input character string storage unit 14 stores the input character strings in duplicate.

  The registration unit 15 stores the same input character string input a predetermined number of times or more in the registered character string storage unit 12 and registers the input character string. The input character string storage unit 14 is read, and the number of duplicate input times of the input character string stored in duplicate is counted. If the number of duplicate inputs is equal to or greater than a predetermined number, the input character string is stored in the registered character string 12.

  The threshold value to be compared with the number of duplicate inputs is stored in the threshold value storage unit 16. The registration unit 15 reads the threshold value stored in the threshold value storage unit 16 and compares it with the counted number of duplicate inputs. The threshold storage unit 16 is a storage area configured by the RAM 107b. The threshold value is read from the HDD 107 c at the time of presetting and stored in the threshold value storage unit 16.

  When storing in the registered character string storage unit 12, the registered character string storage unit 12 is read to search for the presence of a registered character string composed of the same character string as the input character string to be registered. If the same registered character string does not exist, the input character string to be registered is stored in the registered character string storage unit 12. The registration unit 15 displays a pop-up window in which a message for selecting whether or not registration is necessary is displayed on the monitor 106, and when there is an input for selecting the registration necessity from the operation panel 109, the registration character string storage unit 12 You may make it memorize.

  When the input character string to be registered is already registered, the registration unit 15 displays a pop-up window describing a message for notifying that the input character string is registered on the monitor 106.

  FIG. 6 is a flowchart showing an annotation display operation of the ultrasonic diagnostic apparatus 100. In the ultrasonic diagnostic apparatus 100, a tomographic image is displayed on the monitor 106 during examination, and character keys, numeric keys, and registered character string display keys are displayed on the operation panel 109.

  If any of the registered character string display keys 112a... Displayed on the operation panel 109 is pressed during the inspection (S01, Yes), the annotation unit 13 displays the registered character string display key 112a. .. Is read from the registered character string storage unit 12 of the HDD 107c (S02). When the registered character string is read, this registered character string is displayed in an overlay on the monitor 106 (S03).

  When a character string is input by pressing a character key or numeric key 113... Displayed on the operation panel 109 during inspection (S01, No, and S04, Yes), the input character string is monitored. The overlay is displayed on 106 (S05), and the displayed input character string is stored in the input character string storage unit 14 of the RAM 107b (S06).

  Further, the registered character string stored in the registered character string storage unit 12 is read from the HDD 107c (S07), and the read registered character string is compared with the input character string (S08). If there is a registered character string composed of the same character string as the input character string (S08, Yes), a pop-up window describing a message notifying that the input character string is registered is displayed (S09).

  That is, in the ultrasonic diagnostic apparatus 100 of this embodiment, all input character strings under examination are temporarily stored in the RAM 107b regardless of duplication.

  FIG. 7 is a flowchart showing an operation for registering an input character string temporarily stored in the RAM 107b. First, a threshold value is read from the HDD 107c in advance at the time of presetting and stored in the threshold value storage unit 16 of the RAM 107b (S11).

  The registration unit 15 reads out the input character string from the input character string storage unit 14 of the RAM 107b using the end of the inspection as a trigger (S12), and counts the number of duplicate input times of the input character string (S13).

  When the counting is completed, the registration unit 15 reads the threshold value from the threshold value storage unit 16, compares the number of duplicate inputs with the threshold value, and searches for an input character string with the number of duplicate inputs equal to or greater than the threshold value (S14). If there is an input character string with the number of duplicate inputs equal to or greater than the threshold (S14, Yes), the registered character string is read from the registered character string storage unit 12 of the HDD 107c (S15). The input character strings are compared, and a registered character string having the same character string configuration as the input character string whose duplicate input count is equal to or greater than the threshold is searched (S16).

  As a result of the search, if there is a registered character string as a registered character string in the input character string for which the number of duplicate inputs is equal to or greater than the threshold (S16, Yes), a pop-up window notifying that the character string has been registered is displayed on the monitor 106. (S17).

  In addition, if there is an unregistered character string in the input character string whose duplicate input count is equal to or greater than the threshold value as a result of the search (S18, Yes), whether or not registration of an unregistered input character string whose duplicate input count is equal to or greater than the threshold value is determined. The accepted pop-up window is displayed on the monitor 106 (S19). When registration is input using the operation panel 109 (S20, Yes), the unregistered input character string for which registration is input is stored in the registered character string storage unit 12 of the HDD 107c (S21).

  Further, in this character string registration process, the input character strings input during the inspection may be displayed in a list after the inspection is completed, and the character string to be registered may be selected from the list display. In this case, counting processing of the number of duplicate inputs by the registration unit 15 and comparison processing with a threshold value can be eliminated.

  FIG. 8 is a flowchart showing a character string registration operation when a character string to be registered is selected. The registration unit 15 reads the input character string from the input character string storage unit 14 of the RAM 107b (S31), and reads the registered character string from the registered character string storage unit 12 of the HDD 107c (S32) with the end of the inspection as a trigger.

  The read input character string is compared with the registered character string, an input character string composed of the same character string as the registered character string is searched, and the presence of the registered input character string is checked (S33).

  When there is a registered input character string, the registered input character string is subjected to emphasis modification such as changing the color, and all the read input character strings are displayed on the monitor 106 without duplication (S34).

  When the operator performs an input for selecting from the input character string displayed on the monitor 106 using the operation panel 109 (S35, Yes), the selected input character string is stored in the registered character string storage unit 12 of the HDD 107c. Store (S36).

  As described above, in the ultrasonic diagnostic apparatus 100 according to the present embodiment, the input character string input during the examination is temporarily stored, and the input character string that is input more than a predetermined number of times is automatically registered after the examination is completed. In addition, a list of input character strings input during the inspection is displayed after the inspection is completed, and selection of a character string to be registered is accepted. Thereby, the character string frequently used for the annotation display can be easily registered, and the troublesomeness related to the registration of the character string to be displayed for annotation is reduced.

  A process of registering a character string by the ultrasonic diagnostic apparatus 100 will be specifically described with reference to FIGS. 4 and 5 and FIGS. 9 to 13 are diagrams showing the console 110 in each registration process. It is assumed that 3 times is set as the threshold for the number of duplicate inputs.

  As shown in FIG. 9, when the input keys 113 on the operation panel 109 are pressed in a predetermined order, the characters assigned to the input keys 113 are displayed in order on the image of the monitor 106 as a character string. For example, when each input key 113 is pressed in the order of constituting the character string F, the character string F is displayed on the monitor 106. When each input key 113 is pressed in the order of forming the character string G, the character string G is displayed on the monitor 106.

  As shown in FIG. 4, the character string F has already been registered as a registered character string. In this case, as shown in FIG. 10, a registered notification window 114 for notifying that the character string F has been registered is displayed on the monitor 106.

  As shown in FIG. 5, the character string G has been input more than 3 times, which is the threshold for the number of duplicate inputs in the current input. In this case, as shown in FIG. 11, a registration necessity selection pop-up window 115 for selecting whether or not to register the character string G is displayed on the monitor 106. When an OK button indicating that the registration requirement is selected is pressed on this pop-up window, the character string G is stored in the registered character string storage unit 12.

  When the inspection is completed, as shown in FIG. 12, the input character strings G, H, and J that are not stored in the registered character string storage unit 12 but are stored in the input character string storage unit 14 are displayed as a list. An input character string list pop-up window 116 for selecting whether or not to register each of the input character strings G, H, and J is displayed on the monitor 106. This pop-up window displays check buttons corresponding to the input character strings G, H, and J. Further, if there is a registered character string in the input character string, the character string is highlighted with an underline 117 or the like. When a check button corresponding to an input character string to be registered is checked and a registration button indicating that selection of registration is selected is pressed, the checked registered character string is stored in the registered character string storage unit 12. For example, when the check button corresponding to the input character string G is checked and the registration button is pressed, the input character string G is stored in the registered character string storage unit 12.

  As shown in FIG. 13, when an input character string G is newly stored as a registered character string, a registered character string display key 112g to which the input character string G is assigned is displayed on the operation panel 109. By pressing the registered character string display key 112g, the character string G is displayed as an annotation on the image of the monitor 106.

  In the present embodiment, the threshold value to be compared with the number of duplicate inputs may be stored in the threshold value storage unit 16 as a value input by the operator using the operation panel 109.

  Further, the input character string storage unit 14 sequentially stores the input character strings regardless of duplication. In addition to this, the input character string storage unit 14 stores the input character string and the number of times of repeated input. When the same input character string as the input character string already stored is input, the number of times of repeated input Is counted up, updated and stored, and it is not necessary to store it repeatedly.

  In addition, the input character string storage unit 14 is copied to the HDD 107c after the registration process is completed and retained after the operation of the ultrasonic diagnostic apparatus 100 is completed, and the ultrasonic diagnostic apparatus 100 is started and terminated a plurality of times. The number of duplicate inputs may be counted as a span. The span for counting the number of duplicate inputs is set for each activation, a predetermined number of activations, or the number of days. The span is set using the operation panel 109, the setting is confirmed after registration is completed, and copied to the HDD 107c. What should I do?

  As described above, in the present embodiment, the example in which the annotation display function is implemented in the ultrasonic diagnostic apparatus 100 has been described. The input character string registration technique of the present invention can be implemented in an apparatus having an annotation display function such as an X-ray CT apparatus, an X-ray diagnosis apparatus, an MRI apparatus, and a nuclear medicine diagnosis apparatus in addition to the ultrasonic diagnosis apparatus. .
