Hereinafter, embodiments of the image processing apparatus and the program will be described in detail with reference to the drawings.

(First Embodiment)
FIG. 1 is a block diagram showing an example of a magnetic resonance imaging (MRI) apparatus 100 according to an embodiment. The magnetic resonance imaging device 100 is an example of an image processing device according to the present embodiment.

The magnetic resonance imaging device 100 includes a static magnetic field magnet 101, a static magnetic field power supply (not shown), a gradient magnetic field coil 103, a gradient magnetic field power supply 104, a sleeper 105, a sleeper control circuit 106, a transmission coil 107, and transmission. It includes a circuit 108, a receiving coil 109, a receiving circuit 110, a sequence control circuit 120, and a computer system 130.

The configuration shown in FIG. 1 is only an example. For example, each part in the sequence control circuit 120 and the computer system 130 may be integrated or separated as appropriate. The magnetic resonance imaging device 100 does not include the subject P (for example, the human body).

The X-axis, Y-axis, and Z-axis shown in FIG. 1 constitute an apparatus coordinate system unique to the magnetic resonance imaging apparatus 100. For example, the Z-axis direction coincides with the axial direction of the cylinder of the gradient magnetic field coil 103, and is set along the magnetic flux of the static magnetic field generated by the static magnetic field magnet 101. Further, the Z-axis direction is the same direction as the longitudinal direction of the sleeper 105, and is also the same direction as the head-to-tail direction of the subject P placed on the sleeper 105. Further, the X-axis direction is set along the horizontal direction orthogonal to the Z-axis direction. The Y-axis direction is set along the vertical direction orthogonal to the Z-axis direction. In the present embodiment, the term "circle" includes an ellipse.

The static magnetic field magnet 101 is a magnet formed in a hollow substantially cylindrical shape, and generates a static magnetic field in the internal space. The static magnetic field magnet 101 is, for example, a superconducting magnet or the like, and is excited by receiving a current supply from a static magnetic field power source. The static magnetic field power supply supplies a current to the static magnetic field magnet 101. As another example, the static magnetic field magnet 101 may be a permanent magnet, and in this case, the magnetic resonance imaging device 100 may not be provided with a static magnetic field power supply. Further, the static magnetic field power supply may be provided separately from the magnetic resonance imaging device 100.

The gradient magnetic field coil 103 is a hollow coil formed in a substantially cylindrical shape, and is arranged inside the static magnetic field magnet 101. The gradient magnetic field coil 103 is formed by combining three coils corresponding to the axes of X, Y, and Z orthogonal to each other, and these three coils individually supply current from the gradient magnetic field power supply 104. In response, a gradient magnetic field is generated in which the magnetic field strength changes along the X, Y, and Z axes. Further, the gradient magnetic field power supply 104 supplies a current to the gradient magnetic field coil 103 under the control of the sequence control circuit 120.

The sleeper 105 includes a top plate 105a on which the subject P is placed, and the top plate 105a is inserted into the imaging port with the subject P such as a patient placed under the control of the sleeper control circuit 106. do. The sleeper control circuit 106 drives the sleeper 105 under the control of the computer system 130 to move the top plate 105a in the longitudinal direction and the vertical direction.

The transmission coil 107 excites an arbitrary region of the subject P by applying a high-frequency magnetic field. The transmission coil 107 is, for example, a whole body type coil that surrounds the whole body of the subject P. The transmission coil 107 receives an RF pulse from the transmission circuit 108 to generate a high-frequency magnetic field, and applies the high-frequency magnetic field to the subject P. The transmission circuit 108 supplies RF pulses to the transmission coil 107 under the control of the sequence control circuit 120.

The receiving coil 109 is arranged inside the gradient magnetic field coil 103, and receives a magnetic resonance signal (hereinafter, referred to as MR (Magnetic Resonance) signal) emitted from the subject P due to the influence of a high frequency magnetic field. When the receiving coil 109 receives the MR signal, it outputs the received MR signal to the receiving circuit 110.

In FIG. 1, the receiving coil 109 is provided separately from the transmitting coil 107, but this is an example and is not limited to the configuration. For example, a configuration in which the receiving coil 109 is also used as the transmitting coil 107 may be adopted.

The receiving circuit 110 performs analog-to-digital (AD) conversion of the analog MR signal output from the receiving coil 109 to generate MR data. Further, the receiving circuit 110 transmits the generated MR data to the sequence control circuit 120. The AD conversion may be performed in the receiving coil 109. Further, the receiving circuit 110 can perform arbitrary signal processing other than AD conversion.

The sequence control circuit 120 takes an image of the subject P by driving the gradient magnetic field power supply 104, the transmission circuit 108, and the reception circuit 110 based on the sequence information transmitted from the computer system 130. Sequence information is information that defines a procedure for performing imaging. The sequence information includes, for example, the strength of the current supplied by the gradient magnetic field power supply 104 to the gradient magnetic field coil 103 and the timing of supplying the current, the strength of the RF pulse supplied by the transmission circuit 108 to the transmission coil 107, and the timing of applying the RF pulse. , The timing at which the receiving circuit 110 detects the MR signal and the like are included. The sequence control circuit 120 may be realized by a processor or may be realized by a mixture of software and hardware.

When the sequence control circuit 120 receives MR data from the reception circuit 110 as a result of driving the gradient magnetic field power supply 104, the transmission circuit 108, and the reception circuit 110 to image the subject P, the sequence control circuit 120 transfers the received MR data to the computer system 130. Forward.

The computer system 130 performs overall control of the magnetic resonance imaging device 100, generation of an MR image, and the like. As shown in FIG. 1, the computer system 130 includes a NW (network) interface 131, a storage circuit 132, a processing circuit 133, an input interface 134, and a display 135.

The storage circuit 132 stores MR data received by the NW interface 131, k-space data arranged in k-space by the processing circuit 133 described later, image data generated by the processing circuit 133, and the like. The storage circuit 132 is, for example, a RAM (Random Access Memory), a semiconductor memory element such as a flash memory, a hard disk, an optical disk, or the like. Further, the storage circuit 132 may be provided outside the magnetic resonance imaging device 100.

The input interface 134 receives various instructions and information input from the operator. The input interface 134 is, for example, a trackball, a switch button, a mouse, a keyboard, a touch pad for performing an input operation by touching an operation surface, a touch screen in which a display screen and a touch pad are integrated, and a non-optical sensor. It is realized by a contact input circuit, a voice input circuit, and the like. The input interface is connected to the processing circuit 133, converts the input operation received from the operator into an electric signal, and outputs the input operation to the processing circuit 133. In the present specification, the input interface is not limited to the one provided with physical operation parts such as a mouse and a keyboard. For example, an example of an input interface includes an electric signal processing circuit that receives an electric signal corresponding to an input operation from an external input device provided separately from the computer system 130 and outputs this electric signal to a control circuit. .. The input interface 134 is an example of the operation unit in the present embodiment.

The display 135 displays a GUI (Graphical User Interface) for receiving an input of imaging conditions, a magnetic resonance image (MR image) generated by the processing circuit 133, and the like under the control of the processing circuit 133. The display 135 is, for example, a display device such as a liquid crystal display. The display 135 is an example of a display unit. The display 135 may be provided outside the magnetic resonance imaging device 100.

In the present embodiment, the magnetic resonance image includes a positioning image and a diagnostic image. The positioning image is also referred to as a locator image (Locator) or a scout image (Scout). The diagnostic image is imaged based on the FOV (Field Of View) and the slice position determined by the user using the positioning image. The slice position is the position of the imaged cross section in the diagnostic image. In the present embodiment, determining at least the slice position on the positioning image is referred to as positioning.

The positioning image is also referred to as a parent image, and the diagnostic image captured based on the positioning image is also referred to as a child image. Hereinafter, in the present embodiment, the term "magnetic resonance image" simply refers to a diagnostic image.

The processing circuit 133 controls the entire magnetic resonance imaging device 100. More specifically, the processing circuit 133 includes, as an example, an image pickup processing function 133a, a display control function 133b, a reception function 133c, a selection function 133d, and an image processing function 133e. The image pickup processing function 133a is an example of the image pickup processing unit. The display control function 133b is an example of a display control unit. The reception function 133c is an example of the reception unit. The selection function 133d is an example of a selection unit. The image processing function 133e is an example of an image processing unit.

Here, for example, each processing function of the image pickup processing function 133a, the display control function 133b, the reception function 133c, the selection function 133d, and the image processing function 133e, which are the components of the processing circuit 133, is in the form of a program that can be executed by a computer. Is stored in the storage circuit 132. The processing circuit 133 is a processor. For example, the processing circuit 133 realizes a function corresponding to each program by reading the program from the storage circuit 132 and executing the program. In other words, the processing circuit 133 in the state where each program is read out has each function shown in the processing circuit 133 of FIG. Although it has been described in FIG. 1 that the processing functions performed by the display control function 133b, the reception function 133c, the selection function 133d, and the image processing function 133e are realized by a single processor, a plurality of independent functions are realized. Processors may be combined to form a processing circuit 133, and each processor may execute a program to realize a function. Further, in FIG. 1, a single storage circuit 132 has been described as storing a program corresponding to each processing function, but a plurality of storage circuits are distributed and arranged, and the processing circuit 133 is stored from an individual storage circuit. It may be configured to read the corresponding program.

In the above description, an example in which the "processor" reads a program corresponding to each function from the storage circuit and executes the program has been described, but the embodiment is not limited to this. The word "processor" is used, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an application specific integrated circuit (ASIC), and a programmable logic device (for example, a simple programmable logic device (Simple Programmable)). It means a circuit such as a Logic Device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA). When the processor is, for example, a CPU, the processor realizes a function by reading and executing a program stored in a storage circuit. On the other hand, when the processor is an ASIC, the function is directly incorporated as a logic circuit in the circuit of the processor instead of storing the program in the storage circuit. It should be noted that each processor of the present embodiment is not limited to the case where each processor is configured as a single circuit, and a plurality of independent circuits may be combined to form one processor to realize its function. good. Further, a plurality of components in FIG. 1 may be integrated into one processor to realize the function.

The image pickup processing function 133a controls each part of the magnetic resonance imaging device 100 to perform imaging of the magnetic resonance image. For example, the imaging processing function 133a executes sequence information generation, MR data collection, k-space data generation, and magnetic resonance image generation. The generation of a magnetic resonance image means that the k-space data is subjected to a reconstruction process such as a Fourier transform. Further, the image pickup processing function 133a may execute various corrections on the reconstructed magnetic resonance image.

In the present embodiment, the image pickup processing function 133a captures a positioning image and a diagnostic image.

The display control function 133b displays a plurality of diagnostic images and a plurality of inset images representing the positions of the captured cross sections in each of the plurality of diagnostic images in association with each other on the display 135.

The inset image is an example of a position display image in this embodiment. An image in which an inset image is superimposed on a diagnostic image and displayed is called an inset image. Not only the inset image but also the reference image described later may be used as an example of the position display image.

Here, the relationship between the positioning image, the diagnostic image, the reference image, the inset image, and the inset image in the present embodiment will be described with reference to examples.

FIG. 2 is a diagram showing an example of the positioning image 9 according to the first embodiment. Further, FIG. 3 is a diagram showing an example of diagnostic images 8a to 8o according to the first embodiment. The diagnostic images 8a to 8o are imaged based on the result of positioning based on the positioning image 9. When the positioning image 9 is used as the parent image, the diagnostic images 8a to 8o are child images of the positioning image 9. Hereinafter, when the individual diagnostic images 8a to 8o are not distinguished, they are simply referred to as diagnostic images 8.

FIG. 4 is a diagram showing an example of the reference image 91 according to the first embodiment. The reference image 91 is an image in which reference lines 6a to 6p are superimposed on the positioning image 9. Reference lines 6a to 6p represent the positions of the cross sections of each of the plurality of diagnostic images 8 captured with the positioning image 9 as the parent image. Hereinafter, when the reference lines 6a to 6p are not particularly distinguished, they are simply referred to as reference lines 6.

Further, FIG. 5 is a diagram showing an example of an image 7 with an inset according to the first embodiment. As shown in FIG. 5, the inset image 7 includes a diagnostic image 8 and an inset image 92 showing the position of the imaged cross section of the diagnostic image 8.

The inset image 92 is smaller than the diagnostic image 8 and is displayed superimposed on the diagnostic image 8. Further, the inset image 92 is an image in which one reference line 6 is superimposed on the positioning image 9. While the reference image 91 described with reference to FIG. 4 is superposed with a plurality of reference lines 6a to 6p representing the positions of the respective imaging cross sections of the plurality of diagnostic images 8, the inset image 92 is displayed. One reference line 6 corresponding to one diagnostic image 8 is displayed. The image area in which the inset image 92 is displayed is called an inset frame.

The positioning image 9, the diagnostic image 8, the reference image 91, and the inset image 92 of the present embodiment are medical images compliant with DICOM (Digital Imaging and Communications in Medicine) standards. Each medical image can be identified by a unique image identifier (Image Instance UID). Further, the incidental information of the reference image 91 and the inset image 92 includes the image identifier of the positioning image 9 included in the reference image 91 and the inset image 92. Further, the incidental information of the inset image 92 includes information indicating the position of the imaged cross section corresponding to the reference line 6 displayed on the inset image 92.

Further, in FIG. 5, one image 7 with an inset is shown independently for the sake of explanation, but the display control function 133b can display a plurality of images 7 with an inset on the display 135 at the same time.

In the present embodiment, a filming process is given as an example in which a plurality of images 7 with insets are displayed. The filming process includes an image process for printing a medical image on a film and a print layout adjustment process. In this embodiment, a filming process for printing a magnetic resonance image on a film will be described as an example.

Includes at least one change in (Window Width: WW). Pan is the movement of the displayed image range. Note that these processing contents are examples, and the contents of image processing are not particularly limited.

FIG. 6 is a diagram showing an example of the virtual film editing screen 50a according to the first embodiment. The display control function 133b causes the virtual film editing screen 50a to be displayed on the display 135.

The virtual film editing screen 50a includes a virtual film 5 and edit boxes 51a to 51c.

On the virtual film 5, a plurality of inset images 7a to 7k and reference images 91 to be printed on the film are arranged according to the user's operation. Hereinafter, when the individual inset images 7a to 7k are not distinguished, it is simply referred to as an inset image 7. Further, when the individual inset images 92a to 92k are not distinguished, it is simply referred to as an inset image 92.

Although the reference numeral of the diagnostic image 8 is omitted in FIG. 6, the image 7 with the inset is the same as the diagnostic image 8 on the virtual film editing screen 50a shown in FIG. 6 as in FIG. , Inset image 92 showing the position of the imaging cross section of the diagnostic image 8.

In the present embodiment, arranging the image 7 with an inset on the virtual film 5 means registering the image 7 with an inset on the virtual film 5. In addition to the inset image 7, the reference image 91 or the diagnostic image 8 without the inset may be registered on the virtual film 5.

The inset images 92a to 92k registered in the virtual film 5 shown in FIG. 6 are images with insets in the positioning image 9 used for positioning the diagnostic image 8 included in each of the inset images 7a to 7k. It is an image which displayed the position of the imaging cross-section in each of the diagnostic images 8 included in each of 7a to 7k.

The user can perform image processing operations on the plurality of inset images 92a to 92k included in the plurality of inset images 7a to 7k on the virtual film 5 shown in FIG.

Parameter values used for image processing can be input by the user in the edit boxes 51a to 51c. In the present embodiment, the parameter values that can be input to the edit boxes 51a to 51c are numerical values. A window value can be input to the edit box 51a. Further, the window width can be input to the edit box 51b. An enlargement ratio can be input to the edit box 51c. That is, the value of the parameter that defines the content of the image processing corresponding to each edit box 51a to 51c can be set as a numerical value.

The number of edit boxes 51a to 51c and the types of parameters shown in FIG. 6 are examples, and are not limited thereto. Hereinafter, when the individual edit boxes 51a to 51c are not particularly distinguished, they are simply referred to as edit boxes 51. The check box 54 labeled "Select inset frame" in FIG. 6 is a check box for enabling / disabling the function of collectively selecting a plurality of inset images 92 by the operator. When the check box 54 is checked, for example, when an area containing a plurality of inset images 7 is selected by a drag operation with a mouse, the plurality of diagnostic images 8 included in the selected area are displayed. Only a plurality of inset images 92 are selected without being selected. If the check box 54 is not checked, for example, the plurality of inset images 92 included in the area selected by the drag operation are not selected, and only the plurality of diagnostic images 8 are selected.

Returning to FIG. 1, the reception function 133c accepts various operations by the user via the input interface 134. For example, the reception function 133c accepts an operation of a user who registers an image 7 with an inset on the virtual film 5.

Further, the reception function 133c accepts an operation of a user who designates a plurality of inset images 92 included in the plurality of inset images 92 displayed on the display 135 as selection targets.

FIG. 7 is a diagram illustrating an example of a selection target designation operation according to the first embodiment. In the example shown in FIG. 7, among the plurality of inset images 92a to 92k displayed on the display 135, the plurality of inset images 92a to 92g are designated as selection targets by the user's operation.

The number of inset images specified as selection targets is not particularly limited. One inset image 92 may be designated as a selection target, or all of a plurality of inset images 92a to 92k displayed on the display 135 may be designated as selection targets. Further, not only the inset image 92 but also the reference image 91 may be designated as the selection target.

The reception function 133c notifies the selection function 133d, which will be described later, of a plurality of inset images 92 designated as selection targets by the operation of the reception user.

Further, the reception function 133c accepts image processing according to the user's operation. More specifically, the reception function 133c accepts a user's operation instructing image processing for a plurality of inset images 92 selected by the selection function 133d described later.

The operation of the user instructing the image processing is, for example, an operation of inputting a parameter value in the edit box 51. In this embodiment, the parameter values are set numerically. The reception function 133c accepts image processing according to at least one numerical value input as a parameter value by the user.

Further, the user's operation instructing the image processing accepts the image processing according to the operation amount of the input interface 134 by the user. For example, when the user moves the mouse while pressing a predetermined button of the mouse on the selected inset image 92, the reception function 133c accepts the enlargement operation of the inset image 92. The enlargement ratio is determined according to the amount of movement. The image processing specified by the user may differ depending on the moving direction of the mouse. For example, the upward movement may be an operation instructing enlargement, and the downward movement may be an operation instructing reduction. Further, for example, when the user moves the mouse on the selected inset image 92 while pressing a predetermined button of the mouse different from that at the time of the enlargement operation, the reception function 133c accepts the pan operation according to the movement direction. .. The allocation of mouse buttons according to the operation may be changed by the user.

Further, the reception function 133c sends the content of the operation by the user to the image processing function 133e described later. For example, the reception function 133c sends the image processing parameter value input to the edit box 51 by the user to the image processing function 133e described later. Further, the reception function 133c sends the content of the image processing according to the operation amount of the input interface 134 by the user to the image processing function 133e described later.

Returning to FIG. 1, the selection function 133d selects a plurality of inset images 92a to 92g included in the plurality of inset images 92a to 92k displayed on the display 135. The selection function 133d of the present embodiment selects a plurality of inset images 92a to 92g designated as selection targets by the user. The plurality of inset images 92a to 92k are examples of the plurality of first position display images in the present embodiment. Further, the inset images 92a to 92g are examples of a plurality of second position display images in the present embodiment. When the reference image 91 is included in the selection target, the selection function 133d also selects the reference image 91.

The image processing function 133e collectively applies image processing based on the user's operation to the plurality of selected inset images 92a to 92g or the reference image 91.

For example, in the example shown in FIG. 7, among the plurality of inset images 92a to 92k displayed on the display 135, the plurality of inset images 92a to 92g are designated as selection targets by the user's operation. When the image processing operation is performed by the user in this state, the image processing function 133e collectively applies the image processing to the plurality of inset images 92a to 92g. More specifically, in FIG. 7, the enlargement ratio of "150.0%" is input by the user in the edit box 51c.

In this case, the image processing function 133e simultaneously performs "150.0%" enlargement processing on the inset images 92a to 92g. Further, for the unselected inset images 92h to 92k and the reference image 91 among the inset images 92a to 92k displayed on the display 135, the image processing function 133e is set to “150.0”. % ”Is not expanded.

Although the virtual film 5 for one sheet is displayed in FIGS. 6 and 7, the virtual film editing screen 50a may include the virtual film 5 for a plurality of sheets. For example, the display control function 133b may change the sheet to be displayed according to the user's operation such as scrolling operation or selection of the number of sheets. In the present embodiment, the inset image 92 that can be designated as a selection target by the user is the inset image 92 registered in the sheet displayed on the virtual film editing screen 50a. If the user desires image processing for the inset image 92 registered in the sheet not displayed on the virtual film editing screen 50a, the user performs an operation to display another sheet. When the reception function 133c accepts the operation, the display control function 133b displays the sheet designated by the user. In this case, as described with reference to FIGS. 6 and 7, the user designates a desired inset image 92 as a selection target in the newly displayed sheet, and operates an image processing operation on the designated inset image 92. It can be performed.

Although FIG. 7 illustrates a case where a plurality of inset images 92a to 92g are collectively subjected to image processing, the user performs an operation of individually performing different image processing on each inset image 92. May be. Further, in the present embodiment, the image processing for the inset image 92 has been mainly described, but the user may also perform an operation of performing image processing on the diagnostic image 8 included in the inset image 7. good. For example, when a plurality of diagnostic images 8 are designated as selection targets by the user, the image processing function 133e may collectively perform image processing on the plurality of diagnostic images 8.

Next, the flow of image processing executed by the magnetic resonance imaging apparatus 100 of the present embodiment configured as described above will be described.

FIG. 8 is a flowchart showing an example of the flow of image processing according to the first embodiment. As a premise of the processing of this flowchart, it is assumed that the positioning image 9 and the plurality of diagnostic images 8 based on the positioning image 9 have already been captured. The positioning image 9 and the diagnostic image 8 are stored in, for example, a storage circuit 132.

For example, the reception function 133c determines whether or not the operation for starting the filming process by the user has been accepted (S1). When the reception function 133c has not received the operation to start the filming process (S1 “No”), the reception function 133c repeats the process of S1.

Further, when the reception function 133c accepts the operation for starting the filming process (S1 “Yes”), the reception function 133c notifies the display control function 133b that the operation for starting the filming process has been accepted. In this case, the display control function 133b causes the virtual film editing screen 50a to be displayed on the display 135 (S2).

Then, the reception function 133c determines whether or not the operation of the user who specifies the image 7 with the inset to be registered in the virtual film 5 has been accepted (S3). When the reception function 133c does not accept the operation of the user who specifies the image 7 with the inset to be registered (S3 “No”), the reception function 133c repeats the process of S3.

When the reception function 133c accepts the operation of the user who specifies the image 7 with the inset to be registered (S3 “Yes”), the display control function 133b registers the selected image 7 with the inset in the virtual film (S3 “Yes”).

Here, as shown in FIGS. 6 and 7, it is assumed that the inset images 7a to 7k and the reference image 91 are registered.

Then, the reception function 133c determines whether or not the operation of designating the selection target by the user has been accepted (S5). When the reception function 133c determines that the operation for designating the selection target by the user is not accepted (S5 "No"), the process of S5 is repeated. Here, as shown in FIG. 7, among the inset images 92a to 92k included in the inset images 7a to 7k, the inset images 92a to 92g are designated as selection targets by the user's operation. do. In this case, the reception function 133c determines that the operation for designating the selection target by the user has been accepted (S5 “Yes”).

Then, the selection function 133d selects a medical image designated as a selection target by the user (S6). Here, the selection function 133d selects the inset images 92a to 92g designated as the selection target.

Next, the reception function 133c determines whether or not the user has accepted the image processing operation (S7). When the reception function 133c does not accept the image processing operation (S7 “No”), the reception function 133c repeats the processing of S7. Here, as shown in FIG. 7, it is assumed that the enlargement ratio of "150.0%" is input by the user in the edit box 51c as an operation of image processing.

Then, the image processing function 133e applies image processing to the selected medical images in a batch (S8). Here, the image processing function 133e performs "150.0%" enlargement processing on the selected inset images 92a to 92g.

Then, the reception function 133c determines whether or not the operation for ending the filming process by the user has been accepted (S9). If the reception function 133c has not received the operation for ending the filming process (S9 “No”), the process returns to the process of S5. Further, when the reception function 133c accepts the operation for terminating the filming process (S9 “Yes”), the process of this flowchart ends.

As described above, the magnetic resonance imaging apparatus 100 of the present embodiment collectively applies image processing to the plurality of selected inset images 92. Therefore, according to the magnetic resonance imaging apparatus 100 of the present embodiment, the user does not have to individually perform image processing operations on the individual inset images 92, and therefore, when editing a plurality of inset images 92. It is possible to reduce the workload of the user in.

Further, the magnetic resonance imaging apparatus 100 of the present embodiment selects a plurality of inset images 92 designated as selection targets by the user, and collectively applies image processing to the selected plurality of inset images 92. do. Therefore, according to the magnetic resonance imaging apparatus 100 of the present embodiment, the user can collectively perform image processing on an arbitrary plurality of inset images 92. As a result, it is possible to reduce the difference in the result of the image processing as compared with the case where the user individually performs the image processing on the individual inset images 92.

Further, the magnetic resonance imaging apparatus 100 of the present embodiment accepts image processing according to at least one numerical value input by the user. Therefore, when performing image processing on a plurality of inset images 92 included in different sheets, the user can perform image processing with the same contents by inputting the same numerical value, and the visual and operational feeling can be improved. Dependent work can be reduced.

Further, the magnetic resonance imaging device 100 of the present embodiment accepts image processing according to the amount of operation of the input interface 134 by the user. Therefore, according to the magnetic resonance imaging apparatus 100 of the present embodiment, it is possible to perform image processing based on the user's interval operation, and the selected inset images 92 can be subjected to image processing. The image processing can be applied collectively.

(Second embodiment)
In the first embodiment described above, the inset image manually designated by the user as the selection target is selected as the batch application target of the image processing. In this second embodiment, the selection of the inset image is automatically executed.

The magnetic resonance imaging apparatus 100 of the present embodiment has the same hardware configuration as that of the first embodiment. Further, the processing circuit 133 of the present embodiment includes an image pickup processing function 133a, a display control function 133b, a reception function 133c, a selection function 133d, and an image processing function 133e, as in the first embodiment. The image processing function 133a and the image processing function 133e have the same functions as those in the first embodiment.

The reception function 133c of the present embodiment has the same function as that of the first embodiment, and also performs an operation of a user who specifies at least one inset image 92 among a plurality of inset images 92 displayed on the display 135. accept.

Further, the selection function 133d of the present embodiment has the same function as that of the first embodiment, and the inset image 92 including the same positioning image 9 as the positioning image 9 included in the inset image 92 designated by the user. Select. That is, in the present embodiment, the selection function 133d automatically includes the inset image 92 including the same positioning image 9 as the designated inset image 92 in addition to the inset image 92 itself manually specified by the user. select.

Further, the selection function 133d of the present embodiment also designates the inset image 92 included in the sheet that is not displayed on the display 135 at the time of selection by the user among the inset images 92 registered in the virtual film 5. If it contains the same positioning image 9 as the positioning image 9 included in the inset image 92, it is selected. The inset image 92 included in the sheet that is not displayed on the display 135 at the time of selection by the user is an example of a plurality of inset images 92 that are not displayed on the display 135 in the present embodiment. That is, in the selection function 133d of the present embodiment, the inset image 92 including the same positioning image 9 as the positioning image 9 included in the inset image 92 designated by the user is registered in the virtual film 5. Of the 92, at least one of the inset image 92 displayed on the display 135 and the inset image 92 not displayed at the time of selection by the user is selected.

FIG. 9 is a diagram showing an example of the virtual film editing screen 50b according to the second embodiment.

The display control function 133b of the present embodiment displays the virtual film editing screen 50b on the display 135. The virtual film editing screen 50b does not have to include the edit box 51 when operations such as enlargement can be performed by user operations on the image.

In the example shown in FIG. 9, the virtual film editing screen 50b includes two sheets of virtual films 5a and 5b. When the virtual film 5a on the first sheet and the virtual film 5b on the second sheet are not particularly distinguished, it is simply referred to as the virtual film 5. Further, the virtual films 5a and 5b for two sheets may not be displayed at the same time on the virtual film editing screen 50b, and may be displayed for one sheet at a time.

In the virtual films 5a and 5 on the virtual film editing screen 50b, a plurality of inset images 7 included in the five series 40a to 40e and reference images 91a to 91e are registered. A series is a unit that represents a set of multiple medical images. In general, a plurality of series are included in one examination, and a plurality of medical images are included in one series.

Series 40a-40d include inset images 71 including diagnostic images 8 taken based on the same positioning image 9. Further, the reference images 91a to 91d included in the series 40a to 40d are images in which a plurality of reference lines 6 indicating the imaging cross-sectional positions in each series are superimposed on the same positioning image 9.

For example, the inset images 71a-71g included in the series 40a include a diagnostic image 8 taken at a cross-sectional position corresponding to each of the plurality of reference lines 6 described in the reference image 91a. Further, the inset images 71a to 71g include inset images 921a to 921g including the same positioning image 9 as the reference image 91a. The inset images 921a to 921g each include one reference line 6 indicating the imaging cross-sectional position of the diagnostic image 8 included in the inset images 71a to 71g.

Further, the series 40e includes an inset image 71 including a diagnostic image 8 captured based on a positioning image 9 different from the series 40a to 40d. Further, the series 40e includes a reference image 91e in which the reference line 6 is superimposed on the positioning image 9 different from the reference images 91a to 91d included in the series 40a to 40d.

For example, when the user specifies the inset image 921a and then performs an image processing operation to enlarge the inset image 921a, the selection function 133d has the same positioning as the positioning image 9 included in the inset image 921a. Select the inset image 921 including the image 9.

In the example shown in FIG. 9, the inset image 921 including the same positioning image 9 as the positioning image 9 included in the inset image 921a is all the inset images 921 included in the series 40a to 40d. Further, the selection function 133d also selects reference images 91a to 91d including the same positioning image 9 as the positioning image 9 included in the inset image 921a.

Virtual film editing screen 50b When virtual films 5 for a plurality of sheets are included, the selection function 133d specifies a selection target from the inset image 921 and the reference image 91 included in all the sheets. For example, as shown in FIG. 9, even when the inset image 921 or the reference image 91 including the same positioning image 9 as the positioning image 9 included in the inset image 921a is registered over a plurality of pages, the selection is made. Function 133d selects these inset images 921 or reference images 91 from a plurality of pages.

The selection function 133d determines whether or not the inset image 921 and the reference image 91 registered in the virtual film 5 include the same positioning image 9 as the positioning image 9 included in the inset image 921a specified by the user. It is specified based on the image identifier of the positioning image 9 included in the incidental information of each inset image 921 and each reference image 91. Specifically, the selection function 133d includes the same image identifier of the positioning image 9 as the image identifier of the positioning image 9 included in the incidental information of the positioning image 9 included in the inset image 921a designated by the user in the incidental information. The inset image 921 and the reference image 91 are selected.

Since the series 40e does not include the inset image 921 or the reference image 91 including the same positioning image 9 as the positioning image 9 included in the inset image 921a specified by the user, the selection function 133d is a series. The inset image 921 or the reference image 91 of 40e is not selected.

When the reference image 91 is specified by the user, the image processing is applied from the inset image 921 and the reference image 91 registered in the virtual film 5 in the same manner as when the inset image 921a is specified. The inset image 921 and the reference image 91 are selected. The inset image 921 and the reference image 91 to which the image processing is applied include the same image identifier of the positioning image 9 as the image identifier of the positioning image 9 included in the incidental information of the reference image 91 specified by the user in the incidental information. Inset image 921 and reference image 91.

In the present embodiment, when the inset image 921a is specified by the user, the selection function 133d searches only the incidental information of the inset image 921 and the reference image 91, and makes a diagnosis registered in the virtual film 5. The incidental information of the image 8 is excluded from the search target.

FIG. 10 is a flowchart showing an example of the flow of image processing according to the second embodiment. The process from the determination process of accepting the start operation of the filming process of S1 to the registration of the virtual film of S4 is the same as the process of the first embodiment described with reference to FIG.

Further, the reception function 133c determines whether or not the operation of the user who specifies the inset image 921 or the reference image 91 and performs image processing is accepted (S101). When the reception function 133c determines that the operation of the user who specifies the inset image 921 or the reference image 91 and performs the image processing is not accepted (S101 "No"), the processing of S101 is repeated.

When it is determined that the reception function 133c has accepted the operation of the user who specifies the inset image 921 or the reference image 91 and performs the image processing (S101 “Yes”), the selection function 133d determines the designated inset image 921 or the reference. An inset image 921 or a reference image 91 including the same positioning image 9 as the positioning image 9 included in the image 91 is selected (S102).

Then, the image processing function 133e collectively applies image processing based on the user's operation to the inset image 921 or the reference image 91 selected by the selection function 133d (S8). After the process of determining the end of the filming process of S9, the process is the same as that of the first embodiment described with reference to FIG.

As described above, the magnetic resonance imaging apparatus 100 of the present embodiment accepts the operation of the user who designates at least one inset image 921 out of the plurality of inset images 921 displayed on the display 135, and is designated by the user. The inset image 921 including the same positioning image 9 as the positioning image 9 included in the inset image 921 is selected. Therefore, according to the magnetic resonance imaging apparatus 100 of the present embodiment, in addition to the same effect as that of the first embodiment, the same positioning image 9 can be obtained without the user manually selecting the individual inset image 921. The same image processing can be uniformly applied to the included inset image 921.

Generally, the display size of the inset image 921 on the display 135 is small and no incidental information is displayed. However, according to the magnetic resonance imaging apparatus 100 of the present embodiment, the inset image including the same positioning image 9 by the user is included. The inset image 921 to be image-processed can be automatically selected without the work of visually finding the 921.

Further, when the user manually specifies the selection target, the inset image 921 of the selection candidate must be displayed on the display 135 as a premise, but when the inset image 921 is automatically selected, the inset image 921 must be displayed. The inset image 921 registered in the non-displayed sheet can also be selected, and the inset image 921 to be image-processed can be selected over a plurality of sheets.

(Modification 1)
In each of the above-described embodiments, the inset images 92, 921 or the reference image 91 registered in the virtual film 5 are the targets of the batch image processing, but the inset images 92 newly registered in the virtual film 5 are targeted. , 921 or the reference image 91 may also be the target of batch image processing.

FIG. 11 is a diagram showing an example of the virtual film editing screen 50c according to the modified example 1. The virtual film editing screen 50c of this modification is a screen on which a plurality of diagnostic images 8 and inset images 92 to be printed on the film can be edited. The display control function 133b of this modification causes the virtual film editing screen 50c to be displayed on the display 135.

More specifically, the virtual film editing screen 50c of the present modification includes the virtual film 5c, the mainframe 52, and the registration candidate image selection field 53.

In the selection field 53 of the registration candidate image, for example, a plurality of diagnostic images 8 are arranged and displayed in a matrix defined by a series and a slice position. The user selects one or a plurality of diagnostic images 8 among the plurality of diagnostic images 8 displayed in the selection field 53 of the registration candidate image, and then presses the registration button 501, whereby the selected plurality of diagnoses are diagnosed. The image 8 can be designated as a registration target in the virtual film 5c.

The reception function 133c of this modification accepts a user's operation instructing image processing for the inset image 92 newly registered in the virtual film 5c on the virtual film editing screen 50c.

In the example shown in FIG. 11, the virtual film 5c has an inset including a diagnostic image 8 designated as a registration target from the registration candidate image selection field 53 and an inset image 92 corresponding to the diagnostic image 8. The reference image 91 corresponding to the diagnostic image 8 registered from the image 7 and the selection field 53 of the registration candidate image is registered.

The mainframe 52 is an image area in which a user can edit various medical images registered in the virtual film 5c or medical images newly registered in the virtual film 5c.

In the example shown in FIG. 11, the mainframe 52 has an inset including a diagnostic image 8 designated as a registration target from the selection field 53 of the registration candidate image and an inset image 92 corresponding to the diagnostic image 8. Image 7 is displayed. The inset image 7 is a medical image newly registered in the virtual film 5c. The display control function 133b refers to the image identifier of the positioning image 9 used for acquiring the diagnostic image 8 included in the incidental information of the diagnostic image 8, and displays the inset image 92 corresponding to the image identifier. By displaying it on the main frame 52 of 135, the image 7 with an inset is displayed.

When the user performs an image processing operation on the inset image 92 displayed on the main frame 52, the selection function 133d of this modification is the inset image 92 or the reference image 91 already registered in the virtual film 5c. Among them, the inset image 92 or the reference image 91 including the same positioning image 9 as the positioning image 9 included in the newly registered inset image 92 is selected.

As the selection method, for example, as in the second embodiment, the search by the image identifier of the positioning image 9 can be adopted. When the virtual film 5c includes a plurality of sheets, the selection function 133d selects the corresponding inset image 92 or the reference image 91 from all the sheets, as in the second embodiment. The selection method may be selected by the user as in the first embodiment.

Then, the image processing function 133e of this modification collectively applies the image processing received from the user to the newly registered inset image 92 and the inset image 92 selected by the selection function 133d. The user may be able to set whether or not to collectively apply the image processing operations performed on the mainframe 52.

Although the image processing for the newly registered inset image 92 is taken as an example in FIG. 11, when the image processing operation for the newly registered reference image 91 is performed, the virtual film 5c is already formed in the same manner. Among the registered inset images 92 or reference images 91, the inset image 92 or the reference image 91 including the same positioning image 9 as the positioning image 9 included in the newly registered inset image 92 is collectively. Image processing may be performed.

According to the magnetic resonance imaging apparatus 100 of this modification, the image processing for the newly registered inset image 92 can be collectively applied to the inset image 92 or the reference image 91 already registered in the virtual film 5c. Therefore, in addition to the effects of each of the above-described embodiments, it is possible to reduce the time and effort for the user to edit the individual inset images 92 or reference images 91 already registered in the virtual film 5c one by one.

Further, when the user performs an image processing operation on the inset image 92 displayed on the mainframe 52, the application target of the image processing is limited to the newly registered inset image 92, or has already been applied. The user may be able to select whether to apply the inset image 92 or the reference image 91 registered in the virtual film 5c at once.

For example, the display control function 133b is limited to the inset image 92 in which the image processing operation is newly registered for the inset image 92 displayed on the main frame 52 on the virtual film editing screen 50c. A first operation unit that can be specified by the user and a second operation unit that can be specified by the user to be collectively applied to the inset image 92 or the reference image 91 already registered in the virtual film 5c are displayed. May be.

(Modification 2)
In the second embodiment described above, the selection function 133d selects the inset image 92 including the same positioning image 9 as the positioning image 9 included in the inset image 92 in which the user has performed an image processing operation. However, you may also add conditions to the selection.

The selection function 133d of this modification does not select an inset image 92 including the same positioning image 9 included in the inset image 92 specified by the user and which does not satisfy the specified conditions.

For example, the defined condition is that the position of the imaged cross section is within a specified distance from the position of the imaged cross section of the inset image 92 selected by the user.

The distance between the imaging cross sections may be the distance on the inset image 92 of the reference line 6 on the inset image 92 selected by the user and the reference line 6 on the inset image 92 registered in the virtual film 5. , The distance converted into the distance on the body of the imaged subject P may be used. For example, the selection function 133d may set the distance between the plan centers of the diagnostic images 8 corresponding to each inset image 92 as the distance between the imaging cross sections. The plan center of the diagnostic image 8 is the center of the imaging range set in the positioning for imaging the diagnostic image 8. Further, the selection function 133d may calculate the distance between the imaging cross sections based on the information on the position of the imaging cross section registered in the incidental information of each inset image 92.

Further, the length of the specified distance is not limited, but may be, for example, a length such that the image pickup target portion imaged on the diagnostic image 8 changes. Further, the specified distance may be changeable by the user.

For example, even in a plurality of inset images 92 including the same positioning image 9, when the positions of the reference lines 6 are separated from each other, if the enlargement ratio of one inset image 92 is applied to another inset image 92, another The reference line 6 of the inset image 92 of the above may be out of the inset frame and may not be displayed. The selection function 133d reduces such a phenomenon by selecting only the inset image 92 whose position of the imaged cross section is within a specified distance from the position of the imaged cross section of the inset image 92 selected by the user. be able to.

Further, when the imaging range of the positioning image 9 is wide, the positioning image 9 may include a plurality of imaging portions of the positioning image 9. In such a case, it may not be appropriate to apply image processing to one part to another part. Therefore, the selection function 133d selects only the inset image 92 whose position of the imaged cross section is within a predetermined distance from the position of the imaged cross section of the inset image 92 selected by the user, thereby performing batch image processing. The target of application can be appropriately restricted.

Further, the specified conditions may differ depending on the type of image processing. For example, whether to apply the specified conditions for each image processing such as enlargement, reduction, pan, brightness change, rotation, annotation addition, ROI addition, filter, window value change, or window width change. It may be configurable by the user. For example, as the default setting, the above-mentioned specified conditions may be set for the enlargement process, but the specified conditions may not be set for the window value and the window width. Further, the length of the distance between the imaging cross sections set as a predetermined condition may be different for each type of image processing.

Further, the specified conditions are not limited to the above examples. For example, it may be a predetermined condition that the imaging target sites are the same.
