Description

  The present invention relates to an ultrasonic diagnostic apparatus, a medical image processing apparatus, and a medical image processing program for displaying a medical image such as an ultrasonic image acquired in the past during diagnosis or treatment using an ultrasonic diagnostic apparatus.

  Conventionally, a medical image diagnostic apparatus such as an ultrasonic diagnostic apparatus uses a thumbnail function for displaying a list of medical image data or a Patient Browser function for displaying a list of medical image data of a patient. By using such a function, in the course of treatment, a list of past image data obtained in past examinations is displayed, and the site to be treated can be confirmed, or compared with medical images obtained at the time of treatment. (For example, Patent Document 1 and Patent Document 2).

  Here, an example of a conventional workflow when referring to a medical image in the course of treatment will be described with reference to FIGS. FIG. 7 is a diagram showing an example of a conventional workflow when referring to a medical image in the course of treatment. FIG. 8 is a screen diagram showing a display example of a medical image in the prior art.

  In this example, a case will be described in which an ultrasound image is acquired by an ultrasound diagnostic apparatus and the tumor is cauterized by an RFA apparatus (radiofrequency ablation apparatus) while observing the ultrasound image. Normally, a plurality of examinations and examinations using different medical image diagnostic apparatuses (modalities) are performed before the treatment of the tumor. In this example, a case will be described in which an examination is performed using an ultrasonic diagnostic apparatus and an X-ray CT apparatus, and RFA ablation treatment is performed after the examination under the guide of the ultrasonic diagnostic apparatus.

<Inspection>
(Step S20)
First, in order to find a tumor, an examination is performed using an ultrasonic diagnostic apparatus. For example, tomographic image data of the liver is acquired using an ultrasonic diagnostic apparatus in order to find a liver tumor with the liver as a target site. The tomographic image data acquired by this examination is stored in a recording device of an ultrasonic diagnostic apparatus or stored in a medical image database via a network.

(Step S21)
Next, in order to distinguish the found tumor state, a contrast medium is injected into the subject and a contrast examination is performed. Here, tomographic image data representing the state of contrast agent injection is acquired using an ultrasonic diagnostic apparatus. The tomographic image data acquired by this examination is stored in a recording device of an ultrasonic diagnostic apparatus or stored in a medical image server via a network.

(Step S22)
Next, a CT image is acquired using an X-ray CT apparatus in order to distinguish the state of the tumor or to make a treatment plan.

  At the time of treatment, a medical image obtained by the above examination is prepared in the form of a film, a photograph, or a medical record. The tomographic image and CT image acquired by the above inspection may be referred to as a “reference image”. This reference image is used for specifying a treatment site at the time of treatment, or is used for judging the effect of treatment after the treatment.

<Treatment>
(Step S23)
For example, a CT image acquired by an X-ray CT apparatus is output to a film and displayed as a film image on Schaukasten, or a tomographic image is output to a photograph to prepare the photograph. Thus, when a film image and a photograph are prepared, the ablation treatment by the RFA apparatus proceeds in the following procedure.

(Step S24)
Under the guidance of the ultrasonic diagnostic apparatus, in order to perform RFA ablation treatment, identification information such as a patient ID is input to the ultrasonic diagnostic apparatus and patient registration is performed.

(Step S25)
Then, the surgeon refers to the film image, photograph, or medical record acquired by the X-ray CT apparatus, or the reference image data stored in the ultrasonic diagnostic apparatus or the medical image database, using the thumbnail function or the patent browser function. Is displayed on the display unit, and the treatment site is specified by referring to the reference image. For example, in order to display the reference image data stored in the ultrasonic diagnostic apparatus or the medical image database on the display unit, the surgeon acquires the file name of the reference image, the patient name, and the medical image diagnostic apparatus that has acquired the reference image. The desired reference image is searched from the medical image database or the recording device of the ultrasonic diagnostic apparatus using the name of the image or the date and time when the reference image is acquired as a search key. Then, by using the thumbnail function or the patent browser function, the retrieved reference image data is read from the medical image database or the recording device of the ultrasonic diagnostic apparatus, and the reference image is displayed as a thumbnail on the display unit. Is displayed. When the surgeon selects a desired reference image from the list, the selected reference image is enlarged and displayed, and can be compared with the currently acquired ultrasonic image.

  For example, as shown in FIG. 8, a list 100 of searched reference images 100 is displayed on the screen 110 of the display unit by using a thumbnail function or a patent browser function (thumbnail display). Then, when the surgeon selects a desired reference image from the reference image list 100, the selected reference image 101 is enlarged and displayed on the screen 110 of the display unit. Moreover, the tomographic image 102 currently acquired with the ultrasonic diagnostic apparatus is displayed on the screen 110 of the display unit by photographing with the ultrasonic diagnostic apparatus. In this manner, the current tomographic image 102 and the reference image 101 are displayed on the screen 110 of the display unit, and the treatment site is specified by comparing them.

(Step S26)
The surgeon compares the reference image 101 displayed on the screen 110 of the display unit with the current tomographic image 102 to determine a route for inserting the puncture needle, and moves the puncture needle along the route. Pierce and perform cauterization treatment.

(Step S27)
In order to evaluate the progress of cauterization during treatment, it is necessary to compare the medical image before cauterization with the current medical image. In that case, the desired reference image is searched again from the recording device of the ultrasonic diagnostic apparatus or the medical image database by using the thumbnail function or the patent browser function, the reference image data is read, and the reference image is displayed on the display unit. indicate. Specifically, the surgeon uses a medical image database or ultrasonic wave as a search key using the file name of the reference image, the patient name, the name of the medical image diagnostic apparatus that acquired the reference image, or the date and time when the reference image was acquired. It is necessary to retrieve a desired reference image from the diagnostic apparatus. Then, the surgeon compares the reference image with the current tomographic image, evaluates the effect of treatment, and determines the necessity for additional treatment.

<After treatment>
(Step S28)
For example, when ablation treatment is performed for liver cancer, it takes several days to one week to finally determine a necrosis area due to cauterization. In order to determine the effect of ablation treatment after one week, the reference function necessary for the determination is searched from the ultrasonic diagnostic apparatus or medical image database again using the thumbnail function or the Patient Browser function, and displayed on the display unit. Will be displayed.

(Step S29)
Then, the surgeon acquires the current tomographic image of the patient using the ultrasonic diagnostic apparatus, and compares the current tomographic image with the reference image to observe the progress of treatment.

  By the way, when a treatment is performed while referring to a medical image, the treatment is often performed while observing a plurality of reference images. As described above, when a plurality of reference images are acquired by performing examinations using a plurality of different medical image diagnostic apparatuses, it is necessary to search and display the plurality of reference images on the display unit during treatment. Further, when a desired reference image does not exist in the recording apparatus of the ultrasonic diagnostic apparatus, it is necessary to search the medical image database via the network.

  However, conventionally, since a series of reference image data necessary for treatment is not prepared in advance, when displaying a desired reference image during treatment, a recording device or a medical image of an ultrasonic diagnostic apparatus is sometimes displayed. It was necessary to search the database and display the necessary reference images on the display unit. In situations where treatment must be performed in a limited time, the time required for searching and ordering becomes a critical issue for treatment. In particular, since a large amount of ultrasonic image data is generated in the ultrasonic diagnostic apparatus, it takes time to select a desired reference image from a large amount of ultrasonic image data.

  For example, when an examination using an ultrasonic diagnostic apparatus or an X-ray CT apparatus is performed over a plurality of days, it is necessary to search for reference images acquired on a plurality of days during treatment. There is. In this case, since the date of the reference image spans a plurality of days, there is a problem that it takes time to search.

  In addition, it is necessary to search for a desired reference image every time before treatment, during treatment, and after treatment, or search for a desired reference image every time when the progress of treatment is observed. There is a problem that takes time and effort.

  Furthermore, the registrant who performed the examination and registered the reference image may be different from the operator who performs the treatment (the user of the reference image). Thus, if the registrant and the surgeon (user) are different, there is also a problem that the surgeon (user) cannot easily search for and use the reference image.

  In addition, if the reference image data stored in the recording device of the ultrasonic diagnostic apparatus is read or the reference image data stored in the medical image database is read via the network, the reading may take time. is there. In particular, when the number of reference images to be read is large, when moving images are read, or when 3D image data is read, the reading time becomes long. For example, a minute order time may be required for reading an image. It may not be acceptable during the treatment to require minutes of time to read an image. In other words, during treatment, it is necessary to quickly display a reference image necessary at the time of treatment. During the treatment, there is also a demand for the operator to see the reference image within a few seconds after the operator has imagined the desired reference image.

  Conventionally, medical images acquired by an X-ray CT apparatus, an MRI apparatus, or the like have been output to a film or a photograph, and thus cannot be compared with the current ultrasonic image on the screen of the display unit. .

  Further, conventionally, it is necessary to set the position of the cross section of the reference image and the display format of the three-dimensional image during the treatment, and there is a problem that it takes time to set. For example, there is a problem that it takes time to obtain a desired reference image because it is necessary to determine the position of a cross section in MPR processing, the direction of the line of sight in rendering, and the like during treatment. In addition, when displaying a moving image as a reference image, it is necessary for the operator to adjust the display speed in order to display a necessary part at a desired display speed, but the adjustment takes time. There is also. During treatment, the adjustment time may not be acceptable.

(Constitution)
The configuration of the ultrasonic diagnostic apparatus according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of an ultrasonic diagnostic apparatus according to an embodiment of the present invention.

  The ultrasonic diagnostic apparatus 1 according to this embodiment creates and stores in advance a list (reference image list) indicating a storage location of medical image data (reference image data) acquired in the past by the medical image diagnostic apparatus. Then, at a desired timing, reference image data is acquired based on the storage location of the reference image registered in the reference image list, and the reference image is displayed. In this way, by creating a reference image list in advance, it is possible to quickly acquire and display a desired reference image when it is necessary to observe the reference image.

  The ultrasonic diagnostic apparatus 1 is connected to a medical image diagnostic apparatus 20 and a medical image server 21 via a network N. The medical image diagnostic apparatus 20 is an ultrasonic diagnostic apparatus, an X-ray CT apparatus, an MRI apparatus, or an X-ray diagnostic apparatus. The medical image server 21 acquires and stores medical image data acquired by the medical image diagnostic apparatus via the network N. Hereinafter, each part of the ultrasonic diagnostic apparatus 1 will be described.

  The ultrasonic probe 2 is a one-dimensional ultrasonic probe in which a plurality of ultrasonic transducers are arranged in a line in a predetermined direction (scanning direction), or a plurality of ultrasonic transducers arranged in a matrix (lattice) shape. It consists of a two-dimensional ultrasonic probe, transmits ultrasonic waves to the subject, and receives reflected waves from the subject as echo signals. The ultrasonic probe 2 includes an ultrasonic transducer, an acoustic matching layer, a backing material, and the like. The ultrasonic transducer transmits an ultrasonic wave to the subject based on the drive signal from the transmission / reception unit 3, receives a reflected wave from the subject, and converts it into an electrical signal. The acoustic matching layer is provided on the ultrasonic transducer and matches the acoustic impedance between the ultrasonic transducer and the subject. The backing material prevents ultrasonic waves from propagating backward from the ultrasonic transducer.

  The transmission / reception unit 3 includes a transmission unit and a reception unit. Under the instruction of the control unit 11, the transmission / reception unit 3 supplies an electrical signal to the ultrasonic probe 2 to generate an ultrasonic wave and receives an echo signal received by the ultrasonic probe 2. To do. Data output from the transmission / reception unit 3 is output to the signal processing unit 4.

  A specific configuration of the transmission unit will be described. The transmission unit includes a clock generation circuit, a transmission delay circuit, and a pulsar circuit (not shown). The clock generation circuit is a circuit that generates a clock signal that determines the transmission timing and transmission frequency of the ultrasonic signal. The transmission delay circuit is a circuit that performs transmission focus with a delay when transmitting ultrasonic waves. The pulsar circuit incorporates pulsars corresponding to the number of individual paths (channels) corresponding to each ultrasonic transducer, generates a drive pulse at a delayed transmission timing, and each ultrasonic transducer of the ultrasonic probe 2 To supply.

  The reception unit in the transmission / reception unit 3 includes a preamplifier circuit, an A / D conversion circuit, and a reception delay / addition circuit (not shown). The preamplifier circuit amplifies the echo signal output from each ultrasonic transducer of the ultrasonic probe 2 for each reception channel. The A / D converter circuit A / D converts the amplified echo signal. The reception delay / adder circuit gives a delay time necessary for determining the reception directivity to the echo signal after A / D conversion, and adds the delay time. By the addition, the reflection component from the direction according to the reception directivity is emphasized.

  The connection between the ultrasonic probe 2 and the transmission unit and the reception unit is switched by a T / R switch (not shown) during transmission and reception of ultrasonic waves.

  The B-mode processing unit 41 visualizes echo amplitude information and generates B-mode ultrasonic raster data from the echo signal. Specifically, the B-mode processing unit 41 performs band-pass filter processing on the echo signal output from the transmission / reception unit 3, then detects the envelope of the output signal, and logs the detected data Perform compression processing by conversion.

  In addition, the color mode processing unit 42 performs orthogonal detection processing, autocorrelation processing, and the like on the echo signal output from the transmission / reception unit 3, and based on the Doppler shift component of the delayed and added echo signal The Doppler signal corresponding to the velocity, dispersion, and power of the tissue moving within is obtained.

  A DSC 5 (Digital Scan Converter: digital scan converter) converts ultrasonic raster data into image data represented by orthogonal coordinates in order to obtain an image represented by an orthogonal coordinate system (scan conversion process). For example, the DSC 5 generates tomographic image data as two-dimensional information based on the B-mode ultrasonic raster data. The tomographic image data is output to the display unit 81 via the display control unit 6, and the display unit 81 displays a tomographic image based on the tomographic image data.

  The ultrasonic probe 2, the transmission / reception unit 3, the signal processing unit 4, and the DSC 5 correspond to the “image acquisition unit” of the present invention.

  The cine memory 7 is a memory that stores ultrasonic image data corresponding to a plurality of frames, for example. The display control unit 6 can display the moving image on the display unit 81 by continuously displaying the ultrasonic image data stored in the cine memory 7 (cine display).

  The display control unit 6 causes the display unit 81 to display an ultrasonic image based on the ultrasonic image data and a medical image (reference image) based on medical image data (reference image data) acquired in the past. Further, the display control unit 6 performs various display controls under the control of the control unit 11. For example, the display control unit 6 uses an observation angle, an image (reference image) acquired in the past by a medical image diagnostic apparatus such as an ultrasonic diagnostic apparatus, an X-ray CT apparatus, or an MRI apparatus, and a current ultrasonic image, Image processing for corresponding magnification or positional relationship is performed. In addition, the display control unit 6 performs image processing such as volume rendering and MPR processing (Multi Planar Reconstruction) on the reference image data and the current ultrasonic image data, so that the three-dimensional image data and the MPR of an arbitrary cross section are obtained. Medical image data such as image data is generated. When displaying a moving image, the display control unit 6 causes the display unit 81 to display a predetermined section at a predetermined display speed.

  The reference image list management unit 9 includes a registration unit 91 and an image reading unit 92. Then, the reference image list management unit 9 creates a list (reference image list) indicating the storage location of the medical image data (reference image data) acquired in the past by the medical image diagnostic apparatus under the control of the control unit 11. At a predetermined timing, the reference image data registered in the reference image list is read from the storage location. The display control unit 6 causes the display unit 81 to display a reference image based on the read reference image data. For example, the display control unit 6 displays a list of reference images on the display unit 81 by displaying the read reference images as thumbnails. Hereinafter, the registration unit 91 and the image reading unit 92 will be described in detail.

  The registration unit 91 is designated by the operator for the image recording unit 10 of the ultrasonic diagnostic apparatus 1, the medical image diagnostic apparatus 20 connected via the network N, the medical image server 21, and the media in the peripheral device. The obtained reference image data is searched, and the location information (address) indicating the location where the reference image data is stored and the incidental information (patient name, imaging condition, etc.) attached to the reference image data are acquired. Create a reference image list. This reference image list is configured by associating a file name of a reference image, location information (address) of the reference image, and incidental information attached to the reference image. Then, the registration unit 91 stores the created reference image list in the image recording unit 10. At this time, the registration unit 91 assigns a list name to the reference image list and stores it in the image recording unit 10. The list name can be input by the operator using the input unit 82, and the registration unit 91 adds the list name input by the operator to the reference image list and causes the image recording unit 10 to store the list name.

  For example, when the operator designates the file name of the reference image data using the input unit 82, the registration unit 91 searches for the reference image data to which the file name is assigned, and the location information (address) of the reference image data. ) And additional information (patient name, imaging conditions, etc.) are acquired and a reference image list is created. When the file names of a plurality of reference images are designated, the registration unit 91 searches for a plurality of reference image data, acquires their location information (address) and supplementary information, and the plurality of reference images are obtained. Create a registered reference image list.

  The reference image data searched by the registration unit 91 is not limited to the ultrasonic image data acquired in the past by the ultrasonic diagnostic apparatus 1, but is also a reference acquired by a medical image diagnostic apparatus such as an X-ray CT apparatus or an MRI apparatus. It may be image data. For example, the registration unit 91 searches the medical image diagnostic apparatus 20 and the medical image server 21 connected to the ultrasonic diagnostic apparatus 1 via the network N, and stores location information on medical image data such as CT images and MR images. (Address) and incidental information (patient name, imaging conditions, etc.) are acquired, and a reference image list is created.

  Further, the registration unit 91 may register the image processing conditions (image processing conditions) to be applied to the reference image data and the current ultrasonic image data in the reference image list. This image processing condition is registered for each reference image data registered in the reference image list. When registering the image processing conditions, the reference image list is configured by associating the file name of the reference image, the location information (address) of the reference image, the incidental information attached to the reference image, and the image processing conditions. Will be.

  The image processing conditions include conditions indicating an image observation angle, magnification, or position, image processing conditions such as volume rendering and MPR processing, and a display speed for a moving image. These image processing conditions may be specified by the operator. When the image processing conditions are attached to the reference image data, the attached image processing conditions may be registered in the reference image list.

  Further, the operator may group a plurality of reference images, and the registration unit 91 may register, for each medical image data, classification information indicating a group to which each reference image data belongs in the reference image list. For example, a plurality of reference images are grouped on the basis of a tumor position, a tumor type, an image acquired before treatment, an image acquired after treatment, or the like. Then, the registration unit 91 registers classification information indicating the classification of the group for each reference image data registered in the reference image list. When registering this classification information, the reference image list is configured by associating the file name of the reference image, the location information (address) of the reference image, the incidental information attached to the reference image, and the classification information. It will be.

  The registration unit 91 may register timing information indicating the timing at which the reference image data is acquired by the medical image diagnostic apparatus in the reference image list. This timing is given when a predetermined waveform (for example, R wave) is detected in the electrocardiogram waveform (ECG signal), when a predetermined time has elapsed since the contrast medium was injected into the subject, or by the operator. Any timing is applicable. This timing information is registered for each reference image data registered in the reference image list. In particular, it is preferable to register timing information for moving image data. When this timing information is registered, the reference image list is configured by associating a file name of the reference image, location information (address) of the reference image, incidental information attached to the reference image, and timing information. It will be.

  The registration unit 91 may create a plurality of reference image lists. For example, it is possible to create a reference image list in which reference images for individual patients are registered, or to create a reference image list in which reference images for individual patients are registered with reference images of desired diagnostic sites. It's okay. Such a reference image can be arbitrarily designated and registered by the operator. For example, if a reference image to be referred to from time to time for treatment is registered in the reference image list according to the treatment plan, the reference image necessary for the treatment can be displayed on the display unit 81 and observed at every time of treatment. It becomes.

  In addition, the registration unit 91 can edit the reference image list, delete the registered reference images, or change the order of registration in accordance with an instruction from the operator.

  The image reading unit 92 reads reference image data from the medical image diagnostic apparatus 20, the medical image server 21, or the like based on the location information (address) of the reference image registered in the reference image list at a desired timing. Store in the recording unit 10. For example, when a patient ID or the like is input at the input unit 82 at the start of the examination, the image reading unit 92 reads the reference image data registered in the reference image list and inputs the image recording unit 10 in response to the input. Remember me. The input unit 82 may be provided with a switch for giving an image reading instruction. When the operator presses the switch, the image reading unit 92 may read the reference image data in response to the pressing.

  When the reference image data is read by the image reading unit 92, the display control unit 6 displays the reference image and the ultrasonic image currently acquired by the ultrasonic diagnostic apparatus 1 side by side on the display unit 81, for example. Thus, the reference image displayed side by side with the current ultrasonic image can be selected by the operator from the image group registered in the reference image list. For example, the display control unit 6 displays a list of read reference image data on the display unit 81 by the thumbnail function, and when the operator selects a desired reference image from the list, the selected reference image is displayed as the current reference image. Display alongside the ultrasound image.

  When the image processing conditions are added to the reference image list, the display control unit 6 performs image processing on the reference image data according to the image processing conditions, and displays a list of the reference image data subjected to the image processing. It is displayed on the display unit 81. For example, when a condition indicating the observation angle, magnification, or position of the image is registered in the reference image list, the display control unit 6 causes the display unit 81 to display a reference image based on the reference image data according to the condition. When image processing conditions such as volume rendering and MPR processing are registered in the reference image list, the display control unit 6 performs image processing such as volume rendering and MPR processing according to the image processing conditions, and Medical image data such as image data and MPR image data is generated.

  Further, the display control unit 6 performs image processing on the current ultrasonic image data in accordance with the image processing conditions associated with the reference image data selected by the operator. That is, the image processing condition for the current ultrasonic image data is set to the same condition as the image processing condition for the reference image data to be compared.

  For example, the display control unit 6 causes the display unit 81 to display the current ultrasonic image under the same conditions as the observation angle and magnification of the reference image selected by the operator. Thereby, even when the magnification, the observation angle, and the like are different between the current ultrasonic image and the reference image acquired in the past, the display unit 81 can display the image with the same magnification and the observation angle. This makes it easy to compare both images. Also, when performing volume rendering, MPR processing, or the like, the display control unit 6 performs image processing on the current ultrasonic image data according to the image processing conditions associated with the reference image. In this way, the reference image and the current ultrasonic image have the same display format, magnification, observation angle, and the like, making it easy to compare the two images.

  Further, when the operator selects a moving image from the list of reference image data and the display speed for the moving image is registered in the reference image list, the display control unit 6 displays the moving image according to the display speed. 81.

  When the classification information indicating the group to which the reference image data belongs is registered in the reference image list, the display control unit 6 causes the display unit 81 to display a mark for identifying the group. This mark is displayed by changing the color or the shape according to the classification of the group. Thereby, the operator can grasp the type of tumor indicated by the reference image, the position of the tumor, and the like by referring to the mark. In addition, by referring to the mark, it is possible to grasp whether the reference image is an image acquired before the treatment or an image acquired after the treatment.

  Further, when the classification information indicating the group to which the reference image data belongs is registered in the reference image list and the desired group is specified by the operator, the display control unit 6 is specified by the operator. A reference image based on the reference image data belonging to the group may be displayed on the display unit 81. That is, the display control unit 6 causes the display unit 81 to display the reference image based on the reference image data associated with the classification information indicating the designated group. Thereby, only the reference image with the same tumor type is displayed on the display unit 81, only the reference image with the same tumor position is displayed on the display unit 81, or only the reference image acquired before the treatment. Can be displayed on the display unit 81, or only a reference image acquired after treatment can be displayed on the display unit 81. Therefore, only a necessary reference image can be displayed on the display unit 81 according to the treatment plan.

  When timing information is registered in the reference image list, the display control unit 6 causes the display unit 81 to display a reference image based on the reference image data at the timing indicated by the timing information. For example, when a predetermined waveform (for example, R wave) is detected in the electrocardiogram waveform (ECG signal) is registered in the reference image list as timing information, the electrocardiogram waveform (ECG signal) is acquired. However, when the ultrasound image data is acquired by the ultrasound diagnostic apparatus 1, when the waveform indicated by the timing information is detected in the electrocardiogram waveform, the display control unit 6 refers to the timing information associated therewith. A reference image based on the image data is displayed on the display unit 81. Further, the ultrasound diagnostic apparatus 1 is a case where a predetermined time has elapsed since injection of a contrast medium into a subject and is registered in the reference image list as timing information, and the contrast medium is injected into the subject. When the ultrasonic image data is acquired at, when the predetermined time indicated by the timing information has elapsed, the display control unit 6 displays a reference image based on the reference image data associated with the timing information on the display unit 81. Display.

(Operation)
Next, a series of operations by the ultrasonic diagnostic apparatus according to the embodiment of the present invention will be described with reference to FIG. Here, an example of a workflow when referring to a medical image in the course of treatment will be described. FIG. 2 is a flowchart showing a series of operations by the ultrasonic diagnostic apparatus according to the embodiment of the present invention.

  In this example, a case will be described in which an ultrasonic image is acquired by the ultrasonic diagnostic apparatus 1, and a tumor is cauterized by an RFA apparatus (radiofrequency ablation apparatus) while observing the ultrasonic image. In this example, an examination is performed using the ultrasonic diagnostic apparatus 1 and the X-ray CT apparatus before the RFA ablation treatment, and after the examination, the RFA ablation treatment is performed under the guide of the ultrasonic diagnostic apparatus 1. And

<Inspection>
(Step S01)
First, an examination is performed using the ultrasonic diagnostic apparatus 1 in order to find a tumor. For example, the ultrasound diagnostic apparatus 1 is used to acquire liver ultrasound image data (for example, tomographic image data) in order to find a liver tumor with the liver as a target site. The display control unit 6 causes the display unit 81 to display an ultrasonic image (for example, a tomographic image) based on the ultrasonic image data. The operator discovers a target region for inspection by observing the ultrasonic image. In addition, the ultrasonic image data acquired by this inspection is recorded in the image recording unit 10.

(Step S02)
Next, in order to distinguish the found tumor state, a contrast medium is injected into the subject and a contrast examination is performed. Here, ultrasonic image data (for example, tomographic image data) representing the state of contrast agent injection is acquired using the ultrasonic diagnostic apparatus 1. The display control unit 6 causes the display unit 81 to display an ultrasonic image (for example, a tomographic image) based on the ultrasonic image data. The operator determines the state of the tumor by observing the ultrasonic image. In addition, the ultrasonic image data acquired by this inspection is recorded in the image recording unit 10.

(Step S03)
Next, medical image data (tomographic image data) is acquired using, for example, an X-ray CT apparatus in order to identify a tumor state or make a treatment plan. Medical image data acquired by the X-ray CT apparatus is stored in the X-ray CT apparatus or stored in a medical image server connected to the X-ray CT apparatus via the network N. For example, the medical image diagnostic apparatus 20 shown in FIG. 1 is an X-ray CT apparatus, and medical image data acquired by the medical image diagnostic apparatus 20 is stored in the medical image diagnostic apparatus 20 or stored in the medical image server 21. .

  When the examinations from step S01 to step S03 are completed, reference image data necessary for performing treatment is selected from the medical image data such as ultrasonic image data and CT images acquired by the examination and referred to. Create an image list. Note that the tomographic image and CT image acquired by the above examination correspond to medical images acquired in the past, and correspond to the reference image in this embodiment.

(Step S04)
For example, as shown in the conceptual diagram of FIG. 3, the registration unit 91 targets the image recording unit 10 of the ultrasonic diagnostic apparatus 1, the medical image diagnostic apparatus 20 connected via the network N, the medical image server 21, and the like. The reference image data designated by the operator is searched, the location information (address) indicating the location where the reference image data is stored, and the incidental information (patient name and imaging conditions) attached to the reference image data Etc.) to create a reference image list. The reference image list is configured by associating the file name, location information (address), and incidental information of the reference image, and the list name is given by the operator and stored in the image recording unit 10. The operator can register a reference image necessary for treatment in the reference image list by designating a reference image necessary for treatment.

  Further, the registration unit 91 may register the image processing condition in the reference image list when the image processing condition is attached to the reference image data or when the image processing condition is designated by the operator. Further, the operator may group a plurality of reference images, and the registration unit 91 may register classification information indicating the classification of each group in the reference image list.

  Further, the registration unit 91 may change or delete the order of reference images registered in the reference image list in accordance with an instruction from the operator.

  As described above, by registering the file name, location information, and the like of the reference image required at the time of treatment as a reference image list in advance, desired reference image data is obtained based on the reference image list at the time of treatment. Since it can be read into the ultrasonic diagnostic apparatus 1, it is not necessary to prepare film images and photographs and post them on the Schaukasten.

<Treatment>
(Step S05)
In order to perform RFA ablation treatment under the guidance of the ultrasonic diagnostic apparatus 1, identification information such as a patient ID is input to the ultrasonic diagnostic apparatus 1 and patient registration is performed. For example, the operator inputs the patient ID using the input unit 82.

(Step S06)
When the patient ID is input by the input unit 82, for example, as shown in the conceptual diagram of FIG. 4, the image reading unit 92 is based on the location information (address) of the reference image registered in the image reference list. Reference image data is read from the diagnostic device 20 or the medical image server 21 and stored in the image recording unit 10.

(Step S07)
When the reference image data is read by the image reading unit 92, the display control unit 6 causes the display unit 81 to display a list of reference image data by the thumbnail function. For example, as shown in the screen of FIG. 5, the display control unit 6 causes the display unit 81 to display a list 30 of read reference image data.

  When a plurality of image reference lists are created, the display control unit 6 uses the list names 34 of the plurality of image reference lists stored in the image recording unit 10 as shown in the screen of FIG. You may display on the display part 81. FIG. When the operator selects a desired list name necessary for treatment from the list name 34, the image reading unit 92 reads the reference image data registered in the selected reference image list, and the display control unit 6 A list of read reference image data is displayed on the display unit 81.

  When the image processing conditions are added to the reference image list, the display control unit 6 performs image processing on the reference image data according to the image processing conditions, and displays a list of the reference image data subjected to the image processing. It is displayed on the display unit 81.

  Further, when the classification information indicating the group is registered in the reference image list, for example, as shown in the screen of FIG. 5, the display control unit 6 displays the group in the vicinity of each reference image included in the list 30. A mark 31 for identifying is displayed. The mark 31 is displayed by changing the color or the shape according to the group classification. The operator can grasp the type and position of the tumor indicated by the reference image by referring to the mark 31.

  When the classification information indicating the group is registered in the reference image list and a desired group is designated by the operator, the display control unit 6 refers to the reference belonging to the group designated by the operator. A reference image based on the image data may be displayed on the display unit 81.

(Step S08)
When the surgeon selects a desired reference image from the list 30 displayed on the screen 81A of the display unit 81, the display control unit 6 enlarges and displays the selected reference image on the screen 81A of the display unit 81. . Further, by imaging with the ultrasound diagnostic apparatus 1, the ultrasound image 33 (tomographic image) currently acquired by the ultrasound diagnostic apparatus 1 is displayed on the screen 81 </ b> A of the display unit 81. Thus, the surgeon specifies the treatment site by displaying the current ultrasound image 33 and the reference image on the screen 81A of the display unit 81 and comparing them. In the example illustrated in FIG. 5, the display control unit 6 causes the display unit 81 to display the current ultrasound image 33 and the three reference images 32A, 32B, and 32C. These three reference images 32A, 32B, and 32C are images selected by the operator from the list 30. As shown in FIG. 5, four images may be displayed on the display unit 81, or two images may be displayed. When displaying two images, the display control unit 6 causes the display unit 81 to display the current ultrasonic image and the reference image selected by the operator.

  If the image processing conditions are registered in the reference image list, the ideographic control unit 6 performs image processing on the current ultrasonic image data according to the image processing conditions associated with the selected reference image. Apply. Thus, the current ultrasonic image 33, the reference image 32A, and the like can be displayed on the display unit 81 at the same magnification and observation angle, so that both images can be easily compared.

  If the surgeon selects a moving image from the list 30 and the display speed for the moving image is registered in the reference image list, the display control unit 6 displays the moving image on the display unit 81 according to the display speed. Let

  When timing information is registered in the reference image list, the display control unit 6 may display the reference image on the display unit 81 according to the timing information. For example, when an R wave is detected in the electrocardiogram waveform, the display control unit 6 causes the display unit 81 to display a reference image associated with the timing information. Thus, by displaying the reference image on the display unit 81 according to the timing information, it becomes possible to compare the current ultrasonic image and the reference image in the same state.

  As described above, since the reference image necessary for specifying the treatment site is registered in the reference image list and read into the ultrasonic diagnostic apparatus 1 before the start of treatment based on the reference image list, the operator There is no need to search for a reference image during treatment. That is, since the surgeon only has to select a desired reference image from the reference image list, the desired reference image can be quickly selected and displayed on the display unit 81. Conventionally, the surgeon searched for a desired reference image as a standard such as a patient name or a file name, and thus it took time to search, but according to this embodiment, it is necessary to specify a treatment site. Since the reference image is read in the ultrasonic diagnostic apparatus 1 in advance, a desired reference image can be quickly selected and displayed on the display unit 81.

  Then, the surgeon compares the reference image 32A displayed on the screen 81A of the display unit 81 with the current ultrasonic image 33, determines a route for inserting the puncture needle, and moves the puncture needle to the puncture needle. Insert along the route to treat cauterization.

(Step S09)
In order to evaluate the effect of cauterization during treatment, it is necessary to compare the reference image before cauterization with the current ultrasonic image. In that case, the surgeon selects a desired reference image from the list 30 displayed on the screen 81A of the display unit 81, so that the display control unit 6 displays the selected reference image on the screen 81A of the display unit 81. Enlarge and display. Then, the surgeon compares the reference image with the current ultrasonic image, evaluates the effect of treatment, and determines the necessity for additional treatment.

  As described above, the reference image data registered in advance in the reference image list is read into the ultrasonic diagnostic apparatus 1 before the treatment, so that the necessary reference images are quickly displayed on the display unit 81 at the timing of treatment. It becomes possible.

<After treatment>

  For example, when ablation treatment is performed for liver cancer, it takes several days to one week to finally determine a necrosis area due to cauterization. One week later, in order to determine the effect of the cauterization treatment, ultrasonic image data is acquired by the ultrasonic diagnostic apparatus 1 and compared with a reference image acquired in the past.

(Step S10)
First, the operator inputs a patient ID using the input unit 82 and performs patient registration. When the patient ID is input by the input unit 82, the image reading unit 92 receives from the medical image diagnostic apparatus 20 or the medical image server 21 based on the location information (address) of the reference image registered in the image reference list. The reference image data is read and stored in the image recording unit 10. Then, the display control unit 6 causes the display unit 81 to display a list 30 of reference image data, for example, as shown in the screen of FIG.

(Step S11)
Then, the surgeon acquires the current ultrasound image data of the patient using the ultrasound diagnostic apparatus 1 and observes the progress of treatment by comparing the current ultrasound image with the reference image.

  As described above, according to the ultrasonic diagnostic apparatus 1 according to this embodiment, reference images acquired in the past are registered in advance in the reference image list, and the reference images are read according to the reference image list before diagnosis or treatment. By reading, it is possible to quickly switch and display the reference image during diagnosis or treatment. Thereby, an operator such as a doctor observes the current ultrasound image and a desired reference image as appropriate when observing cauterization of the tumor or determining the effect of treatment after treatment. Is possible.

  Further, according to the ultrasonic diagnostic apparatus 1 according to this embodiment, since only a desired reference image can be registered in the reference image list, images that are not necessary for the diagnosis can be obtained during a diagnosis with no time margin. There is no need to refer to it. Thereby, it becomes possible to reduce the work burden during the diagnosis of an operator such as a doctor.

  Also, when the reference image data registered in the reference image list has a large capacity and it takes time to read the reference image data, the reference image data necessary for the treatment is read before the treatment is started. It is not necessary to affect. Further, since the image processing conditions and the like are registered in the reference image list in advance, it is not necessary for the operator to specify the image processing conditions during the treatment. Therefore, it is possible to display a desired reference image on the display unit 81 very easily and quickly.

  In addition, since medical image data acquired by a plurality of different medical image diagnostic apparatuses can be registered in the reference image list, it is necessary to output a CT image, an MR image, etc. to the film before starting the treatment. Disappears.

  Furthermore, even if the registrant who performed the examination and registered the reference image is different from the surgeon performing the treatment, the reference image list shows the reference image necessary for the treatment. By reading the reference image data according to the above, the operator can observe the reference image necessary for the treatment.

(Example of additional registration)
In the ultrasonic diagnostic apparatus 1 according to this embodiment, medical image data newly generated during examination or treatment may be added to the reference image list and registered. An example of this additional registration will be described with reference to FIG. FIG. 6 is an example of a workflow showing a series of operations by the ultrasonic diagnostic apparatus according to the embodiment of the present invention.

  For example, as illustrated in FIG. 6, when the reference image data A and the reference image data B are registered in the reference image list, the reference image data A and the reference image data B are stored in the ultrasound diagnostic apparatus 1 by the image reading unit 92. A list of reference image data is displayed on the display unit 81 by the image recording unit 10 and read by the display control unit 6.

  Then, when ultrasonic image data C and ultrasonic image data D are newly acquired by the ultrasonic diagnostic apparatus 1 and an instruction to register in the reference image list is given by the operator, the registration unit 91 adds a new ultrasonic wave. The image data C and the ultrasonic image data D are registered in the reference image list, and the reference image list is stored in the image recording unit 10. Thereby, the ultrasonic image data C and the ultrasonic image data D can be displayed on the display unit 81 as an example of the reference image 32.

  Furthermore, when ultrasound image data E is newly acquired by the ultrasound diagnostic apparatus 1 and an instruction to register in the reference image list is given by the operator, the registration unit 91 uses the new ultrasound image data E as the reference image. The image is registered in the list, and the reference image list is stored in the image recording unit 10. Thereby, the ultrasonic image data E can be displayed on the display unit 81 as an example of the reference image 32.

  When the operator gives an instruction to clear the reference image list using the input unit 82 at a desired timing, a new reference image list can be selected. For example, the display control unit 6 displays the list name of the reference image list on the display unit 81, and when the desired list name is selected by the operator, the display control unit 6 displays the newly selected reference image list. The registered reference image is displayed on the display unit 81. For example, when the reference image list in which the reference image data F and the reference image data G are registered is selected, the reference image data F and the reference image data G can be displayed on the display unit 81.

  For example, when another part is diagnosed while performing an examination, a reference image corresponding to the other part is selected by selecting a reference image list in which a reference image for the other part is registered. Can be displayed on the display unit 81. In addition, when the reference image of the selected reference image list is not suitable in comparison with the current ultrasonic image, the preferred reference image is displayed on the display unit 81 by switching the reference image list to another list. Can be displayed. As described above, the ultrasonic image data H, I, and J newly acquired by the ultrasonic diagnostic apparatus 1 can be newly registered in the reference image list.

  When the examination or treatment is completed and a new examination or treatment is started, a new reference image list can be created when the operator gives a reset instruction using the input unit 82. For example, a new reference image list can be created by registering reference image data C in a reference image list in which reference image data A and reference image data B are registered.

  By performing the above processing, when a reference image suitable for examination or treatment is not registered in the reference image list, the reference image in which a desired reference image is registered can be obtained by clearing or resetting the reference image list. You can select or create a list.

  Each function of the reference image list management unit 9 according to this embodiment can be obtained by installing a program for executing the function in a computer (medical image processing apparatus) such as a workstation and expanding the program on a memory. realizable. At this time, a program that can cause the computer (medical image processing apparatus) to execute the function is a magnetic disk such as a floppy disk (registered trademark) or a hard disk, an optical disk such as a CD-ROM or DVD-ROM, or a semiconductor memory. It is also possible to store it in a recording medium such as

  Moreover, each function of the reference image list management unit 9 according to this embodiment can be used in combination with a function of an existing ultrasonic diagnostic apparatus. For example, when the reference image registered in the reference image list is acquired by a medical image diagnostic apparatus other than the ultrasonic diagnostic apparatus, the control unit 11 adds the DICOM header information attached to each reference image data. On the basis of this, it is possible to perform a predetermined conversion process on each reference image data, and then store the reference image data in the image recording device 10 and display the reference image data on the display unit 81. Examples of the conversion process include a process of converting a standard of image data acquired by another medical image diagnostic apparatus into a standard of ultrasonic image data acquired by the ultrasonic diagnostic apparatus. For example, the control unit 11 converts the number of bits of medical image data acquired by the X-ray CT apparatus into the number of bits of ultrasonic image data acquired by the ultrasonic diagnostic apparatus, and converts the converted medical image data into an image. Store in the recording unit 10.
