  Embodiments of the present invention will be described below with reference to the drawings.

  The medical image display terminal 101 (also referred to simply as an image display terminal) according to this embodiment has a configuration as shown in FIGS. 1 and 2, and as an example, a tablet terminal or a laptop PC having a touch panel display. It consists of a portable terminal such as a (notebook type PC). FIG. 2 shows an example of a tablet terminal. The medical image display terminal 101 may be configured by installing a medical image display program according to an embodiment of the present invention on a commercially available general-purpose tablet terminal or the like.

  As shown in FIG. 2, in this example, the image display terminal 101 has a thin housing 101a, and a touch panel display 161 'is provided on one of the surfaces. Such an image display terminal 101 may be used by being connected to a hospital system as shown in FIG. 3, for example. The hospital system of this example includes the following devices connected to the network 30: an imaging device 1, a drug solution injection device 10, a hospital information system HIS (Hospital Information System) 21, a radiology information system A certain RIS (Radiology Information System) 22, a picture archiving and communication system PACS (Picture Archiving and Communication Systems) 23, a workstation 24, a printer 25 and the like.

  Examples of the imaging apparatus 1 include imaging apparatuses such as a CT apparatus, an MR apparatus, and an angiography apparatus. Of course, other types of imaging devices may be used, or a plurality of imaging devices of the same type or different types may be used. The drug solution injection device 10 may be a contrast agent injection device for injecting at least a contrast agent, and more specifically, a drive mechanism for pushing out the drug solution from a container (a syringe in one example) filled with the drug solution and its operation It may be provided with a control circuit to control. As an example, a contrast agent injection device having an injection head and a console can be used.

  Referring back to FIG. 1, the image display terminal 1 includes a display 161, a touch panel 163, an input device 165, a communication unit 167, an interface 168, a slot 169, a control unit 150, and a storage unit 159. Note that not all of these are required, and some may be omitted.

  Examples of the display 161 include devices such as a liquid crystal panel and an organic EL panel. A touch panel type display integrally provided with the touch panel 163 can also be used. As a touch panel, a touch panel of a resistive film, electrostatic capacity, electromagnetic induction, surface acoustic wave, infrared or the like can be used. As a specific example, a multi-touch that is a touch at a plurality of positions such as a capacitive type may be detected. The touch operation can be performed using a user's finger, a touch pen, or the like. The touch panel may detect the start of the touch operation on the touch panel, the movement of the touch position, the end of the touch operation, and the like, and output the type of the detected touch and coordinate information.

  Examples of the input device 165 include physical buttons and a microphone. In addition, a detection device such as “Leap sensor” (manufactured by Leap Motion Inc.) capable of non-contact input by the operator may be provided as the input device 165. The “Leap sensor” is an input device that can recognize the movement of the operator's finger and the like without contact, and specifically includes an infrared irradiation unit, an infrared camera, and the like. The position, movement, shape, etc. of the hand or finger in a three-dimensional space are detected in real time by performing image analysis by photographing the reflected light when the irradiated infrared light hits the hand with a camera and performing image analysis . This sensor may be connected to a tablet terminal or a laptop PC in a wired or wireless manner. The connection may be wired to the interface 168, without limitation.

  The communication unit 167 is a unit for enabling communication with an external network or device in a wired or wireless manner. The communication unit 167 may have a transmitter for transmitting data to the outside, a receiver for receiving data from the outside, and the like. The interface 168 is for connecting various external devices and the like, and although only one is shown in the figure, it is needless to say that a plurality of interfaces may be provided.

  The control unit 150 includes a central processing unit (CPU), a memory, and the like, and performs various arithmetic processing. The various processes performed by the control unit 150 may be realized by (i) a computer program or (ii) as hardware by wired logic. In the present embodiment, the control unit 150 includes an image display unit 155a, an operation determination unit 155b, and a display change unit 155c as a conceptual configuration for realizing a predetermined function.

  The image display unit 155a may acquire medical image data of a subject imaged in advance from the outside, create a three-dimensional medical image based thereon, and display the same on the display 161. Alternatively, data of an externally generated three-dimensional medical image may be acquired and displayed on the display 161.

  The image display unit 155a displays, as an example, an anatomical structure such as a liver or a blood vessel as an independent object. In addition, anatomical structures may be automatically recognized and displayed in different colors.

  The operation determination unit 155 b receives an input operation on the touch panel 163 and an input operation on an input device 165 (in particular, a Leap motion sensor or the like). The type of input operation includes, for example, touch operation and predetermined gesture operation (long press operation, swipe operation, drag operation, pinch in operation, pinch out operation, etc.). The operation determination unit 155b determines and receives these inputs.

The image processing unit 155c performs various types of image processing based on, for example, the operation received by the operation determination unit 155b. For example,
-Rotation function, translation function of image displayed in 3D
-Image enlargement / reduction function, image transparency change function,
-The function of switching the display / non-display of an object,
-Object cutting (division) function,
-Object area specification function, etc. The specific contents of these functions will be described in detail in a series of operations described later.

  Referring back to FIG. 1 again, the storage unit 159 may be configured of a hard disk drive (HDD), a solid state drive (SDD), and / or a memory, etc. A program of an OS (Operating System) or a medical image processing program (including algorithm data, graphical user interface data, etc.) according to an aspect of the present invention may be stored. Also, other programs used for various processes, tables, databases, etc. are stored as necessary. The computer program may be executed by being loaded into the memory of the control unit, and may cooperate with hardware such as a CPU to thereby configure the control unit having the functions as in this embodiment. .

  The computer program may be downloaded in whole or in part from an external device as needed via any network. The computer program may be stored in a computer readable recording medium, and the "recording medium" is a memory card, USB memory, SD card (registered trademark), flexible disk, magneto-optical disk, ROM, EPROM, EEPROM, It is intended to include any "portable physical media" such as CD-ROM, MO, DVD, and Blu-ray (registered trademark) Disc. The computer program can also be configured as a program product. The medical image display terminal of the present embodiment may be provided with a slot 169 for reading the storage medium as described above.

(Operation)
Subsequently, an operation example of image display in the medical image display terminal of the present embodiment will be described. FIG. 4A to FIG. 4C schematically show, as an example, images of the liver of the subject and their surroundings, which are captured in advance. Although the following description is based on the assumption that the operator operates the touch panel with a finger, it goes without saying that a touch pen or the like may be used. Although the input on the touch panel will be described as an example, it may be a non-contact input using a Leap motion as a matter of course. The contact-type input means such as a touch panel and the non-contact-type input means such as Leap motion may be provided with both input methods, or only one of them may be provided.

  When the operator performs an operation (for example, touches a predetermined icon or the like on the touch panel) to display a medical image of a subject, the image display terminal 101 is, for example, a medical image as illustrated in FIG. 4A. Display 65. This medical image is, as an example, a three-dimensional image created based on image data obtained by imaging a subject, and here, the anatomical structure of the liver 71 and the blood vessels 73 and 75 is schematically shown. ing.

  The data of the medical image 65 may be read by the image display terminal 101 from an external device connected by wire or wirelessly. The image data may be stored in the storage unit 159 of the image display terminal 101. As the "external device", a predetermined database server, PACS 23, or workstation 24 etc. may be mentioned.

(About various functions)
The image display terminal 101 displays the respective anatomical structures such as the liver 71 and the blood vessels 73 and 75 as independent objects (that is, each can be individually selected or the display can be switched on / off). . Each object is preferably displayed in a different color. For example, at least one of the hepatic artery, portal vein, hepatic vein, and bile duct may be displayed as the blood vessel and the anatomical structure similar thereto.

Examples of basic image processing functions possessed by the image display terminal 101 (or the medical image display program of the present embodiment in another way of understanding) include the following:
-Rotation function-Enlargement / reduction function-Display transparency change function-Display / non-display switching function-Cut function-Area specification function, etc.

  The following will be described in order. Note that not all of these functions need to be provided, and some of them may be omitted.

(Rotation function)
When the operator touches the screen and moves the finger, the image display terminal 101 changes the display direction of the three-dimensional medical image 65 accordingly. Such a rotation function allows the operator to observe a desired target site from any angle.

(Zoom function)
When the operator touches two points on the screen and performs an operation (pinch-out operation, pinch-in operation) to make the distance between the two points separate or move closer, display is made accordingly. Enlarge or display the image that is being With such a function, the operator can easily perform enlargement / reduction of an image and perform confirmation in a desired size simply by moving two fingers on the screen, for example.

(Display transmittance switching function)
The image display terminal 101 changes the display density when the operator touches one of the anatomical structures (for example, the liver 71). Specifically, switching is performed between two states, a normal display state and a semi-transparent state, that is, one touch makes the screen semi-transparent, and tapping again returns to the normal display state It may be like that. In other words, the first transmittance (in one example, the transmittance of 0%) and the second transmittance (semitransparent) are switched. As another mode, for example, the transmittance is set to a plurality of stages such as 0%, 30%, 70%, 100% (not shown), and the display density is sequentially switched each time it is tapped. It is also good. In this case, 100% transparency (that is, the non-displayed state) may be excluded from this loop. As a matter of course, the specific numerical value of the degree of transmission can be changed as appropriate, that is, it is sufficient if the degree of transmission is set to at least a plurality of stages and they are switched.

  According to such a display transmission switching function, the display transmission switching function can be exhibited simply by touching an arbitrary anatomical structure. Therefore, the operation can be performed simply and intuitively, as compared with a method in which it is necessary to separately select an icon or the like or to select a command in order to switch the transparency.

  Further, even when the display is switched to the loop as described above, it is preferable in that it is not necessary to select an icon or the like separately to return to the original display state. Furthermore, since such looped display switching can be realized only by changing the display color of the selected object, it is preferable from the viewpoint of simplification of image processing and operation processing with a small memory.

(Display / non-display switching function)
When the operator touches a predetermined anatomical structure for a certain period of time or more (one example), the image display terminal 101 sets the anatomical structure to the “selected state”. The anatomical structure (for example, the liver 71) may be displayed in a color different from the initial state or may be displayed in a blinking manner to indicate that the "selected state" is present.

  When the operator moves the fingertip (one example) toward the screen edge while touching the anatomical structure (for example, the liver 71) in the selected state (swipe operation, drag operation) Etc.), hide the anatomical structure. In the case of this example, the liver 71 is not displayed, and only the three-dimensional image of the blood vessels 73 and 75 remains.

  Such a feature is useful when the operator only wants to view the desired anatomical structure. Further, as in the present embodiment, according to the method in which the anatomical structure is directly selected and can be hidden only by moving it, for example, the display is switched on / off only by selecting an icon or the like. Operation can be performed more simply and intuitively than in a mode.

  The anatomical structure (for example, the liver 71) that has been hidden once may be displayed as a thumbnail image at the corner of the screen. The thumbnail image may be (i) constantly displayed on the screen, or (ii) may appear after a predetermined operation. The thumbnail image may be one as illustrated in FIG. 4F (described in detail later). Although this figure is for the explanation of the "cut function" to be described later, the thumbnail image 66 can be applied to cases other than the case where the cut function is used. Do. The thumbnail image 66 in the same figure includes an image of an anatomical structure which is hidden in a small window. The size of the thumbnail image 66 is not limited, but may be, for example, about 1/16 or less in area ratio to the display area of the image.

  As the "predetermined operation" for displaying the thumbnail image which is hidden, for example, the operator touches the screen with three or four fingers on the screen in a predetermined direction such as up, down, left, right, etc. It may be an operation to move. When the operation is performed, the image display terminal 101 displays a part of the screen of the thumbnail image 66 which has been in the non-display state.

  The operator touches the thumbnail image 66 and drags, swipes or flicks it toward the screen center side (an example) so that the anatomical structure which has been hidden is displayed again. It may be done. As a matter of course, a configuration is also possible in which an anatomical structure that has been hidden is displayed again simply by touching those thumbnail images 66.

(Cut function)
The cut function is performed as follows. An example in which the liver 71 is cut and then a part thereof is not displayed will be described below. FIG. 5 is a flowchart of a series of operations.

  The image display terminal 101 first displays a medical image 65 as shown in FIG. 4A in step S1. Then, when the operator touches two points on an arbitrary anatomical structure (here, the liver 71) as shown in FIG. 4B, the image display terminal 101 touches the state, ie, two points. It is determined that it has been set (step S2). In addition, as timing, two points may be touched simultaneously or substantially simultaneously.

  Next, in order to exert the function in the case of so-called long press, the image display terminal 101 determines whether the state in which the two points are touched continues for a predetermined time or more (step S3).

  The image display terminal 101 displays on the screen that the two points P1 and P2 being touched have been designated in a predetermined display mode when it is determined in step S3 that the operation is continued for a predetermined time or more. For example, (i) both points P1 and P2 and the line L1 connecting them are displayed, or (ii) only the points P1 and P2 are used. Alternatively, only the line L1 may be displayed. As for the points P1 and P2, they are not just small dots, but a slightly larger graphical image as shown in FIG. 4B (for example, a circle, rectangle, polygon, star, etc., for any shape). Although it does not matter, it is good also as displays, such as a circle illustrated here).

  The image display terminal 101 may display the points P1 and P2 designated as shown in FIG. 4C as they are even after the operator releases the screen. Further, the fine adjustment of the positions of the points P1 and P2 may be received. Thus, for example, the circular graphical image of P1 and P2 and / or the line L1 may be displayed to blink so that it is understood that this mode is for receiving the fine adjustment. In FIG. 4C, as an example, the state in which the point P2 is slightly moved and finely adjusted to the point P2 'is illustrated. This fine adjustment may be performed by the operator moving a graphical image of points P1 and P2, for example, with a finger.

  Thus, after the designation of the points P1 and P2 is finished, in step S4, for example, the operator touches a predetermined icon (for example, an icon for “OK” input) on the screen. Then, by the cutting function, as shown in FIG. 4D, the liver is cut along a line L1 connecting the points P1 and P2 (step S5). The first portion 71-1 and the second portion 71-2 divided into two across the line L1 can be operated as independent anatomical structures. In addition, as a method of the above-mentioned operation unexpected, for example (i) not touching an icon, but by touching a predetermined area on the screen, or (ii) a plurality of times (double tap in one example) common practice The above function may be performed by performing an external operation.

  Therefore, for example, when the first portion 71-1 is touched (step S6), the display density is switched as shown in FIG. 4E by the above-described function. Specifically, only the first portion 71-1 is semitransparent. Return to the original display by touching again.

  Further, for example, when the first part 71-1 is long-pressed and swipe operation or drag operation to the peripheral part side of the screen, the part becomes non-display state, and the second part 71-2 and the blood vessel 73, Only 75 remain.

  The first part 71-1 which is not displayed is displayed as a thumbnail image 66 at the periphery of the screen or, as described above, although it is not displayed at this time, a predetermined operation by the operator ( For example, when an operation of simultaneously moving three or four fingers on the screen is performed, the thumbnail image 66 is displayed. The operation for returning the part in the thumbnail image 66 to the original display is also as described above.

  As in the present embodiment, according to the configuration in which the split function can be exhibited by long-pressing two points, for example, an icon or the like is displayed and compared to the one that exhibits the function by selecting it. Operation can be performed simply and intuitively. In particular, in an operation requiring position specification on an anatomical structure as in the present application, it is possible to perform cutting with one hand and without using a mouse or a dedicated cutting tool. As it is very easy to use and very practical in medical practice.

(Specify area)
The image display terminal 101 designates an area of a part of an anatomical structure by the following operation of the operator. FIG. 6A shows a state in which two points P1 and P2 are touched as in the operation described with reference to FIG. 4B (note that the operator's finger is still in contact with two points on the screen) Although there is no illustration).

  From this state, as shown in FIG. 6B, for example, when the operator moves two fingers (but not limited to simultaneous movement of two fingers), the image display terminal 101 moves The positions of the two subsequent points P1 'and P2' are specified, and a substantially rectangular area is specified based thereon. Specifically, a quadrangle surrounded by four points P1 and P2 before movement and two points P1 'and P2' after movement is designated as an area.

  Again, as in the above case, even if the operator releases the hand, a substantially square area of the designated area remains on the screen, and the positions of the respective points P1, P2, P1 'and P2' are moved individually to It is also preferable that the image display terminal 101 be configured to perform fine adjustment. As a method of determining the designated area, for example, the operator may touch the predetermined icon on the screen (for example, an icon for “OK” input), or Alternatively, the terminal 101 may automatically determine the area when a certain time has elapsed. Note that this is a common matter regardless of the shape of the designated area. Other than input such as operating an icon for "OK" input, (i) by touching a predetermined area on the screen, or (ii) multiple times of touch (in one example, double tap) As described above, this function may be executed by performing an operation.

  When positions of four points P1, P2, P1 'and P2' are designated as shown in FIG. 6B, a circle of points P1, P2, P1 'and P2' (one example) so that each position can be finely adjusted. The graphical images of and the lines connecting them may be displayed blinking.

  The area designated area Sa1 (see FIG. 6B) is divided from other parts and can be operated as an independent object. Therefore, it is possible to change the display density of only the area or to switch the display on / off. According to such a function, it is possible to observe the inner blood vessels 73 and 75 and confirm the relationship between the blood vessels 73 and 75 and the liver 71 by, for example, hiding only the region Sa1.

  Note that the area indication does not necessarily have to be performed in a quadrangle, and a triangular or pentagonal polygon shape or the like may be area designated. Further, although the example of simultaneously moving two fingers as an example to specify the area of the quadrilateral has been described above, the present invention is not limited thereto. For example, an operation of specifying a sector like a compass (see below) is performed multiple times Therefore, it may be such that a rectangle or polygon is designated.

  In the present embodiment, as an example, a substantially fan-shaped area may be specified. For example, from the state in which two points P1 and P2 are touched as shown in FIG. 6C, the operator takes one finger (for example, thumb, point P1) as a rotation center and the other finger (for example, compass) When the index finger and the point P2 are rotated by a predetermined angle, the image display terminal 101 recognizes the movement, specifies the point P2 'of the index finger after movement, and sets three points P1, P2 and P2'. Based on this, a fan-shaped area may be specified. Specifically, a sector defined by a line L1 connecting points P1 and P2, a line L2 connecting points P1 and P2 ', and an arc L3 connecting two points P2 and P2' is an example.

  The designated area Sa2 (see FIG. 7) is divided from the other part of the liver 71 and can be manipulated as an independent anatomical structure as described above. Similar to the above description, the independent object thus divided can be made translucent or completely hidden.

  In the above, the fan-shaped area is specified based on three points P1, P2 and P2 ', but if the above function is used, for example, a circle or a semicircle is specified. You can also FIG. 6C shows an example in which the index finger is turned with the thumb as the rotation center, but the same area specification is possible even if the thumb is rotated with the index finger as the rotation center. It goes without saying that

  In the above description, medical images of the liver and its surroundings are taken as an example, but it goes without saying that the anatomical structure is not limited to a specific one in the present invention. For example, as shown in FIG. 8, a medical image of the head of a subject may be displayed, and various image processing may be performed on it. As an example of image processing, although any of the various functions as described above can be applied, as an example in FIG. 8, a range surrounded by the line L1 with respect to the skull 77 is designated as a region, and the region is not designated. With the display or the semi-transparent display, it is possible to view the blood vessel 78 inside. Although not limited in any way, the area surrounded by the line L1 may be, for example, circular. Naturally, it may be rectangular, fan-shaped, or any other shape.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention can be variously changed in the range which does not deviate from the meaning, and is not limited to the said example.
