FIG. 1 is a block diagram showing a configuration of an information processing system for a medical examination device including RIS1 which is an information processing device for a medical examination device and peripheral devices thereof according to an embodiment of the present invention.

In FIG. 1, the information processing system for a medical examination device includes a RIS 1, a modality terminal device 2, a modality device 3, a HIS 4, a PACS 5, and an electronic medical record system 6. Here, the modality device 3 is, for example, a CR (Computed Radiography) device, a CT (Computed Tomography) device, an MRI (Magnetic Resonance Imaging) device, a DR (Digital Radiography) device, an XA (X-ray Adsorption) device, and a US (Ultra). -Sonic) Medical inspection equipment such as modality equipment such as equipment. The modality terminal device 2 is a console device connected to the modality device 3 and operated by the radiologist 50. However, for the US (Ultra-Sonic) device, the modality terminal device 2 and the modality device 3 are usually integrated. In this case, the modality terminal device 2 shall be read as "modality terminal function unit", and the modality device 3 shall be read as "modality function unit". In addition, the US device is often operated by a doctor. The RIS1 is an apparatus operated by the radiologist 50 and improved as compared with the RIS according to the prior art. HIS4 is an abbreviation for Hospital Information System, which is connected to RIS1, PACS5 and electronic chart system 6, and generally includes a wide range of systems such as automatic reception system, admission and discharge management system, medical accounting system, and pharmacy management system. Including. PACS5 is an abbreviation for an image storage communication system or a picture archiving and communication system, and image data is transmitted from a modality terminal device 2 connected to RIS1, a modality terminal device 2 and HIS4 and having a DICOM transmission function. It can be received, stored in a database, and then, at the request of a client such as a DICOM image viewer, specific image data can be searched for and transferred to RIS1 on the client device side. The electronic medical record system 6 is connected to HIS4, stores the patient's electronic medical record information, and provides it to HIS4 and the like.

The RIS 1 and the modality terminal device 2 are connected via a communication line 31, and the modality terminal device 2 and the modality device 3 are connected via a communication line 32 or a communication line. The RIS 1 transmits the basic information of the patient to be imaged and the examination information (imaging conditions such as site, direction, method, body position, left and right, etc.) to the modality terminal device 2 as text information by MWM. In response to this, the modality terminal device 2 executes shooting with the modality device 3 using the control signal, receives communication data and irradiation data (image data) from the modality device 3, and then transmits the irradiation data by MPPS. Reply to RIS1.

The RIS1 and HIS4 are connected via a communication line 33, the RIS1 and PACS5 are connected via a communication line 34, and the PACS5 and the modality terminal device 2 are connected via a communication line 35. Further, the HIS 4 and the PACS 5 are connected via the communication line 36, and the HIS 4 and the electronic medical record system 6 are connected via the communication line 37. If the thumbnail image is not confirmed by the shooting result confirmation unit 105, which will be described later, the communication line 34 is not particularly required.

FIG. 2 is a block diagram showing the configuration of RIS1 of FIG. In FIG. 2, the RIS1 stores the system control unit 10, the keyboard 11, the mouse 12, the display device 13, the display control unit 14, the RAM 15, the ROM 16, the data control unit 17, the communication interface 18, and the storage. It is configured to include the device 20. The keyboard 11 operates as a data input means for characters and the like, and the mouse 12 operates as a position indicating means. The display device 13 is, for example, a display means such as an LCD, and the display control unit 14 controls the operation of the display device 13 according to an instruction signal of the system control unit 10. The RAM 15 operates as a temporary storage means for the system control unit 10, and the ROM 16 stores the pre-shooting processing program of FIG. 3 and the post-shooting processing program of FIG. 4 in addition to the basic program.

The storage device 20 is composed of, for example, a storage device such as a hard disk drive, and includes master data 21 for storing basic schema original drawings and illustration original drawings, inspection data 22 for storing schema drawings or illustration drawings after a shooting instruction, and the like. It includes contraindication information data 23 which is contraindication information for each imaging condition, medical information data 24 which is medical information of each patient, and a program file 25 for storing, for example, an application program. The master data 21, examination data 22, contraindication information data 23, and medical information data 24 are stored in the storage device 20 as a database 26. The communication interface 18 is connected to the modality terminal device 2, the modality device 3, HIS4, and PACS5 via communication lines 31, 33, and 34, respectively, and transmits and receives predetermined control signals and data.

RIS1 is composed of a digital computer such as a general computer, and preliminarily executes an information processing program (which can be read and executed by a computer) that performs a function peculiar to this apparatus (for example, the processing of FIGS. 2 and 3). It may be installed in the ROM 16 or the storage device 20, or may be stored and supplied in an information processing recording medium such as a CD-ROM. Alternatively, it may be downloadable via a network or communication line.

FIG. 3 is a flowchart showing the pre-shooting process executed by RIS1 of FIG. The pre-imaging process by the radiologist 50 will be described below with reference to FIGS. 5 to 8 and 3 which are examples of the display screen.

An outline of radiography according to the present invention will be described before a detailed description. First, in the imaging method, the imaging position (patient's posture) and imaging direction are determined to some extent depending on the imaging site. For example, the Waters method and the Coldwell method in sinus imaging. In addition, there are standing position, sitting position, lying position, etc. in the shooting position, which are further subdivided. Depending on these shootings, there are table type shooting devices that support lying down and stand types that support standing and sitting positions.

The radiologist first confirms the examination order from the clinical department, etc., and selects an imaging device that suits the examination content. Next, when the basic patient information is read into RIS1, a standard patient schema diagram (three-dimensional human body diagram) 301 and an imaging viewpoint marker 302 corresponding to the basic patient information are generated and displayed. Here, since the imaging viewpoint marker 302 is configured so that the size can be changed according to the size of the imaging recording medium 305 such as a film, an imaging plate, and a flat panel detector, the size is tentatively determined. Next, the movable parts such as the joints of the three-dimensional human body diagram of the patient schema FIG. 301 are changed according to the imaging order. Further, since the imaging viewpoint marker 302 can freely change its spatial position with respect to the patient schema FIG. 301 and can rotate itself, the composition to be imaged is determined by using the function. Here, since the patient schema diagram 301 and the imaging viewpoint marker 302 are operated in a three-dimensional space, it is necessary to confirm what the composition of the imaging schedule is. Therefore, the viewpoint is switched with the visual switching button 106a, and the composition of the patient schema FIG. 301 is confirmed. Further, while performing this confirmation, the size of the shooting viewpoint marker 302 is appropriately changed. The composition is determined by repeating such work.

When the composition of the patient schema FIG. 301 is determined, the patient is asked to take the posture of the composition based on the composition. If there is no particular problem, the final shooting conditions will be decided. The final determined shooting condition before shooting is displayed on the display device 13, and a reduced image of the determined composition is also displayed and can be confirmed. This shooting condition is transmitted to the modality device 3 to perform shooting. It should be noted that this operation is a useful operation when changing the contents of the order from HIS4 or when adding an imaging part.

A detailed embodiment will be described based on the above flow.

First, the radiologist 50 turns on the power of the RIS1 and starts it up. In response to this, for example, the login screen 205 of FIG. 5 is displayed on the display device 13. The radiologist 50 logs in by inputting a login ID and a password using the keyboard 11. Then, for example, the main menu screen 206 of FIG. 6 is displayed on the display device 13. Since the number of reception counters and the number of various examination rooms differ depending on the facility in which the device of the present invention is introduced, this screen can have a screen configuration unique to the facility. Here, when a screen required for each task set in advance is selected, for example, the inspection room menu screen 207 of the predetermined “○○ inspection room” shown in FIG. 7 is displayed. Further, in order to select a patient who needs to be imaged, as shown in FIG. 7, for example, when the mouse 12 is used to move the cursor to the patient to be photographed at a predetermined time of the day from the list of reserved patients, the patient's Basic patient information (customizable) is displayed in the upper left of the screen (Fig. 7). The examination request from the doctor is displayed in the upper right corner of the screen (Fig. 7). As shown in FIG. 7, when the row of the patient to be examined is double-clicked in the reserved patient list, for example, the imaging execution input screen 208 of FIG. 8 is displayed.

In FIG. 8, the imaging execution input screen 208 is an integrated screen for giving radiological imaging instructions while sharing various information, and is customized based on patient-specific information by exchanging the individual function screens constituting the integrated screen. be able to. In the imaging condition indicating unit 106 at the lower left of the imaging execution input screen 208 of FIG. 8, the patient schema FIG. 301, which is a three-dimensional image of the human body for designating the imaging conditions, and the quadrangular pyramid-shaped imaging viewpoint marker 302 (of the imaging device). (For viewpoint setting) is displayed (step S1 in FIG. 3). Here, the photographing viewpoint marker 302 mainly indicates the photographing direction from the origin (X-ray source) of the photographing apparatus, and for example, four on the perpendicular line from the center 302f of the rectangular bottom surface 302S of the quadrangular pyramid of the photographing viewpoint marker 302. The apex 302a of the pyramid is set. At this time, the direction of the line extending from the apex 302a toward the center 302f of the rectangular bottom surface 302S indicates the photographing direction. The area of the rectangular bottom surface 302S of the quadrangular pyramid indicates the photographing range.

As shown in FIG. 19A, the rectangular bottom surface 302S of the quadrangular pyramid of the photographing viewpoint marker 302 is set to a size corresponding to the size of an imaging recording medium (also referred to as an imaging recording medium) 305 such as a film, an imaging plate, and a flat panel detector. be able to. Assuming that FIG. 19A is a chest image taken from the front in a standing position, the X-ray source is arranged on the front side of the chest of the patient schema FIG. 301, and the imaging recording medium 305 set in the imaging device is the back surface of the chest of the patient schema FIG. 301. Suppose it is placed on the side. That is, the rectangular bottom surface 302S and the photographing recording medium 305 form a space of a virtual rectangular parallelepiped 304, and the patient is arranged so as to be sandwiched between the spaces.

Here, the photographing recording medium 305 has a rectangular shape having angles 305b to 305e. The size of the shooting recording medium 305 is half-cut (14 x 17 inches), large angle (14 x 14 inches), large four-cut (11 x 14 inches), four-cut (10 x 12 inches), six-cut (8 x 10). There are inches), etc., and they are used properly depending on the part to be photographed. The photographing recording medium 305 is not displayed as shown by the dotted line. The rectangular bottom surface 302S of the quadrangular pyramid has the same size as when the imaging recording medium 305 is translated by the distance d with respect to the patient schema FIG. 301. Since the patient schema diagram 301 is generated as standard from the basic patient information (height, weight, age, gender, etc.) as described above, the relative size of the patient schema diagram 301 and the imaging recording medium 305 is unique. It has come to be decided.

This makes it possible to select the size of the imaging recording medium 305 suitable for the imaging region and the required number of imaging media. For example, you can choose to take a large-angle image for an adult's chest, a six-cut size for a child's chest, and a large-angle image for an adult's chest with a larger physique.

Note that FIG. 19B is a perspective view showing a modified example of the patient schema FIG. 301 and the imaging viewpoint marker 302 of FIG. 19A. In the modified example of FIG. 19B, the photographing viewpoint marker 302 includes a rectangular parallelepiped 302A having a rectangular bottom surface (rectangular portion) 302S, the rectangular bottom surface 302S, and the surface of the photographing recording medium 305, and the outline is displayed by a solid line. It is characterized by containing a rectangular parallelepiped 304. Here, the rectangular parallelepiped 304 is connected to the square weight 302A so as to include the rectangular bottom surface (rectangular portion) 302S. By including the rectangular parallelepiped (rectangular parallelepiped portion) 304 in the imaging viewpoint marker 302, it is easier to set the patient schema FIG. 301 to be sandwiched between the rectangular bottom surface 302S and the surface of the imaging recording medium 305 as compared with FIG. 19A. There is an advantage of becoming.

The radiologist 50 first sets the patient schema FIG. 301 at a spatial position that is easy to set. The patient schema FIG. 301 can be freely rotated and moved in the three-dimensional direction. In FIG. 8, since the image is taken from the front of the head of the human body, the human body is set in the direction of looking down slightly from above in front of the human body. In FIG. 301, as shown in FIG. 20, which shows another form example, each joint of the human body corresponds to abduction, adduction, abduction, internal rotation, supination, supination, lateral bending, and the like. It can be moved. Next, the imaging viewpoint marker 302 is set in the direction in which imaging is desired with respect to the patient schema FIG. 301. This is done by combining mouse and key operations. In FIG. 8, the setting is such that the image is taken from the front of the head. The photographing viewpoint marker 302 is set on the assumption that the quadrangle of the rectangular bottom surface 302S of the quadrangular pyramid indicates the photographing range and the image is taken in the direction from the apex 302a of the quadrangular pyramid toward the center 302f of the rectangular bottom surface 302S (step S2 in FIG. 3). .. Further, the photographing viewpoint marker 302 can be rotated with respect to an axis extending from the apex 302a of the quadrangular pyramid to the center 302f of the rectangular bottom surface 302S. The movement of the patient schema FIG. 301 and the imaging viewpoint marker 302 may be set by moving any one of them. Further, since the relationship between the imaging viewpoint marker 302 and the patient schema FIG. 301 is expressed in a three-dimensional space, in order to confirm the composition of the patient schema FIG. 301 from the viewpoint of the imaging viewpoint marker 302, the imaging condition indicating unit 106 The viewpoint can be switched and zoomed in by pressing the visual switching button 106a on the upper right (step S3 in FIG. 3). As a result, the screen is switched to the screen showing the shooting state set by the shooting viewpoint marker 302 (or the screen is additionally displayed on the shooting condition indicating unit 106), and it can be confirmed whether the set contents are in the intended direction or range. Further, when the visual switching button 106a is pressed again, the screen is switched to the screen of the original patient schema FIG. 301 and the imaging viewpoint marker 302 (or the additional screen is hidden), and the imaging direction and range can be readjusted.

When the setting of the imaging conditions is completed and the radiologist 50 determines that there is no problem, the confirmation button 106b at the lower right of the imaging condition indicating unit 106 is pressed with the mouse 12 to narrow down the imaging conditions from the patient schema FIG. 301. Determine (step S4 in FIG. 3). Then, for example, the shooting condition setting screen 210 of FIG. 10 is displayed.

The shooting condition setting screen 210 of FIG. 10 includes a shooting condition selection unit 101, a shooting condition candidate display unit 102, and a shooting condition confirmation unit 103. Each imaging condition can be selected from the pull-down candidate list in the imaging condition selection unit 101 in the upper half of the screen of FIG. 10, and conventionally, this portion is customized as one of the function screens to the integrated screen of RIS1 and is a radiologist. 50 selected the shooting conditions. The results based on the selection were listed and displayed as shooting condition candidates on the shooting condition candidate display unit 102 at the lower left of the screen of FIG.

In the present embodiment, since the imaging conditions are determined by the patient schema FIG. 301, which is a three-dimensional image of the human body as shown in FIG. 8, and the imaging viewpoint marker 302, the imaging condition selection unit 101 in the upper half of the screen is practically unnecessary and suddenly. The shooting condition candidate is displayed as character information on the shooting condition candidate display unit 102 at the lower left of the screen.

In the present embodiment, since the shooting condition indicating unit 106 of the shooting execution input screen 208 of FIG. 8 gives an instruction to shoot the head, the shooting condition candidate display unit 102 of FIG. 10 narrows down and lists the candidates related to head shooting. ing. Here, the radiologist 50 makes the final selection regarding the imaging conditions. If there is no problem, the right arrow [→] 102a in the center of the lower half of the screen of FIG. 10 is clicked with the mouse 12 to send it to the shooting condition confirmation unit 103. Here, the shooting conditions of "head and face, supine position" are selected. If this is OK, the content change button 103a on the lower right side of the shooting condition setting screen 210 in FIG. 10 is pressed with the mouse 12, and then the close button 103b is pressed in the same manner to "narrow down". The "shooting condition" is determined as the "shooting instruction condition" (step S5 in FIG. 3). Then, the flow returns to display the shooting execution input screen 211 of FIG. 11 again.

Before the content change button 103a of FIG. 10 is pressed and the shooting execution input screen 211 of FIG. 11 is displayed again, RIS1 automatically confirms the consistency between the selected shooting conditions and the contraindication information data 23 and the like. ing. (Step S6 in FIG. 3) If shooting is possible without any particular problem (YES in step S7 in FIG. 3), the process proceeds to the next step without issuing a warning. On the other hand, if there is a problem based on contraindication information or the like in the automatic confirmation by RIS1 and it is impossible to take a picture (NO in step S7 in FIG. 3), the patient schema of the picture taking condition indicating unit 106 in FIG. A warning is issued by displaying a contraindication mark 303 such as (step S8 in FIG. 3), the process is terminated, and for example, the examination room menu screen 207 in FIG. 7 and the shooting execution input screen 208 in FIG. 8 are displayed. Return the flow as you do. It should be noted that the contraindication is determined by referring not only to the contraindication information data 23 but also to the medical information data 24 (for example, an infectious disease, a diagnosis disease name, etc. as shown in the upper half of the imaging execution input screen 208 in FIG. 8). In some cases.

When the shooting execution input screen 211 of FIG. 11 is displayed again, the content of the shooting condition confirmation unit 103 of the shooting condition setting screen 210 of FIG. 10 is displayed on the shooting condition display unit 107 (step of FIG. 3). 9). And at the right end of the line, the MWM button 107a dedicated to the line is displayed.

Further, a reduced image (photographing instruction condition finally selected by the radiologist) representing the imaging instruction content arranged for each modality of each facility so that it can be confirmed whether the instruction content of the radiologist 50 is as intended. It is possible to display a part 301p of the patient schema FIG. 301 to be imaged in, or the target illustration 104) (step S10 in FIG. 3). The target illustration 104 is, for example, as shown in FIG.

Based on the above, the imaging conditions include a large part, a part, an incident, an imaging direction and method, a posture position, left and right, and a procedure. If the radiologist 50 determines that there is no problem and the imaging conditions are determined, the MWM button 107a at the lower right of the screen or the batch MWM button 211a is pressed using the mouse 12. To perform the inspections one by one, press the MWM button 107a on the right side of the shooting condition display unit 107 on the shooting execution input screen 211. As a result, the RIS1 converts the determined shooting conditions into digital information expressed in the MWM format according to the modality as the shooting instruction conditions and transmits the digital information (step S11 in FIG. 3). If there are multiple series of inspections here, this item is displayed over multiple lines. To collectively transmit these to the modality, press the batch MWM button 211a. At this point, the pre-shooting process ends.

After that, the radiologist 50 moves from the RIS 1 to the modality terminal device 2, and operates the modality device 3 based on the imaging conditions transmitted from the RIS 1 to perform imaging.

It should be noted that when the process first flows from the examination room menu screen 207 of FIG. 7 to the shooting execution input screen 208 of FIG. 8, there is a problem based on contraindication information and the like, and it is clearly impossible to take a picture in this examination room. In some cases, the RIS1 can automatically confirm and display the contraindication mark 303 as shown in FIG. 9 on the patient schema FIG. 301 displayed on the imaging condition indicating unit 106 of the imaging execution input screen 208 of FIG. Further, even when the confirmation button 106b of the shooting condition instruction unit 106 of the shooting execution input screen 208 of FIG. 8 is pressed, the automatic confirmation based on the contraindication information or the like can be activated.

When the imaging location is not the head but the chest, the imaging condition setting screen 213 (including the character information transmission screen) as shown in FIGS. 12 to 13 is displayed. In FIG. 12, the imaging viewpoint marker 302 is set for the chest of the human body in the patient schema FIG. 301. Here, the photographing viewpoint marker 302 has a square pyramid shape having a rectangular bottom surface (rectangular portion) 302S, and the direction of a line extending from the apex 302a toward the center 302f of the rectangular bottom surface 302S indicates the photographing direction. The rectangular bottom surface 302S of the quadrangular pyramid faces the photographing recording medium 305 and has a quadrangle having angles 302a to 302d. Here, the area of the rectangular bottom surface 302S indicates an approximate shooting range corresponding to the shooting recording medium 305. In addition, the imaging condition candidate display unit 108 at the lower left of the screen displays imaging condition candidates related to the chest.

When the shooting location is not the head but the hand, the shooting condition setting screen 215 (including the character information transmission screen) as shown in FIGS. 14 to 15 is displayed. In FIG. 14, the imaging viewpoint marker 302 is set for the chest of the human body in the patient schema FIG. 301. Here, the photographing viewpoint marker 302 also has a square pyramid shape.

It is possible to specify shooting conditions including a shooting direction and a shooting range with respect to 301. Further, the shooting conditions including the instruction content are converted into shooting information of a character string and transmitted to the modality device 3 via the modality terminal device 2 in the form of MWM. Therefore, it is possible to specify the shooting conditions by a simple and visual method as compared with the conventional technique. Further, since the rectangular bottom surface 302S of the imaging viewpoint marker 302 can be adjusted to the size of the imaging recording medium 305, the size of the imaging recording medium 305 suitable for the imaging site can be selected.

(2) RIS1 compares the instructed imaging condition with the contraindication information of the contraindication information data 23 in the storage device 20 and also refers to the medical information data 24 to determine whether or not the imaging condition corresponds to the contraindication. It is automatically determined, and if it corresponds to a contraindication, a warning is issued by displaying the contraindication mark 303 on the patient schema FIG. 301, for example, before taking a picture. Therefore, the radiologist 50 can easily grasp the contraindicated state and interrupt the imaging.
(3) In RIS1, the contents of the imaging conditions instructed by the radiologist 50 with the patient schema FIG. 301 and the imaging viewpoint marker 302 can be confirmed in a reduced image before imaging (step S9 in FIG. 3). Further, the reduced image after shooting is fed back to RIS1 and received, and can be confirmed by the display device 13. In addition, the shooting conditions before shooting can also be displayed. Therefore, the radiologist 50 can easily confirm the imaging conditions before and after imaging and the imaging result in RIS1, the operability of the radiologist 50 can be significantly improved, and the burden of the inspection work can be significantly reduced.

In the above embodiment, the pre-shooting process of FIG. 3 is executed by RIS1, but the present invention is not limited to this, and the pre-shooting process of FIG. 3 is performed on the modality terminal device 2 or a tablet wirelessly or wiredly connected to the modality terminal device 2.
