Description

  The present invention relates to an X-ray imaging system, an X-ray imaging apparatus, and an X-ray detector which acquire an X-ray image of a subject using X-rays.

  In the medical field, an X-ray imaging apparatus for imaging an X-ray image of a subject by irradiating the subject with X-rays is widely used. As one example of the X-ray imaging apparatus, an X-ray tube is provided at one end. There is a C-arm type imaging apparatus provided with a C-type arm provided with an X-ray detector at the other end (see, for example, Patent Document 1). The C-arm type imaging apparatus is suitable for various diagnostic / operative procedures including interventional treatment in that X-ray fluoroscopy and X-ray imaging can be performed from various directions.

  When performing surgery on a subject using an X-ray imaging apparatus such as a C-arm type imaging apparatus, the general procedure for the subject is performed to check the state of the site where the surgery has been performed after completing the surgery. X-ray imaging (general X-ray imaging) is often performed. However, while a relatively large X-ray radiation field is required for general X-ray imaging, the X-ray detector provided in the C-arm type imaging device avoids that the frequently displaced X-ray detector interferes with the operator etc. Generally, one with a small size is used. Therefore, when performing X-ray general radiography using the same C-arm type radiographing device after surgery with a C-arm type radiographing device, it is difficult to obtain high diagnostic X-ray images because the X-ray radiation field is narrow. .

  Therefore, conventionally, in addition to the C-arm type imaging apparatus, a round-table X-ray imaging apparatus that enables movement in a hospital is used (see, for example, Patent Documents 2 and 3). That is, after performing surgery using a C-arm type imaging device, the X-ray imaging device for round examinations is moved to the operating room, and general X-ray imaging is performed on the subject placed on the operating table. Since the size of the X-ray detector provided in the X-ray imaging apparatus for round trips is large, an X-ray image having a wide field of view and being suitable for diagnosis can be acquired by X-ray general imaging.

  As described above, when the general X-ray imaging apparatus is moved to the operating room and X-ray general imaging is performed, the operator needs to confirm a general imaging image, that is, an X-ray image generated by the X-ray general imaging. . As conventional methods for confirming an X-ray image acquired using a round-table X-ray imaging apparatus in an operating room, there are mainly the following three methods.

  As a conventional method, a first example is a method in which X-ray image data of a general radiographed image is displayed on a circulation monitor provided in the circulation X-ray imaging apparatus, and the operator visually recognizes the circulation monitor. In the second example, X-ray image data is transmitted from the round-table X-ray imaging apparatus to a terminal (such as a notebook PC) connected to the round-table X-ray imaging apparatus by wireless communication etc. It is a method of confirming the displayed X-ray image.

  A third example is a method of transferring X-ray image data of a general captured image to a medical image display monitor installed in the operating room from the round-table X-ray imaging apparatus through the server and displaying it. That is, a connector provided in the operating room and a round-table X-ray imaging apparatus are connected by a cable, and the round-table X-ray imaging apparatus transmits X-ray image data to the in-hospital network server via the network. The server transmits and displays the received X-ray image data on a medical image display monitor or the like deployed in the operating room. In this case, the operator confirms the X-ray image by visually recognizing the medical image display monitor.

However, in the case of the conventional example having such a configuration, there are the following problems.
That is, when the conventional method is used to confirm an image related to general X-ray imaging after surgery, there is a concern that the diagnostic capability of the X-ray image is low and the time required to display the X-ray image is long. .

  First of all, the size of the display screen is limited because the size of the display of the notebook PC connected to the monitor (monitor for round diagnosis) provided on the round-table X-ray imaging apparatus and the round-table X-ray imaging apparatus is limited. small. Therefore, the operator frequently moves from the operating table to the vicinity of the round-trip X-ray imaging apparatus, and it is necessary to confirm that the display screen of the round-trip monitor or the notebook PC looks in, increasing the burden on the operator. Further, compared with a medical image display monitor used exclusively for displaying a medical image such as an X-ray image, the round-the-counter monitor and the notebook PC have lower gradation and resolution of the display screen. Therefore, it is difficult to improve the diagnostic ability of the displayed general radiographed image by the method of displaying an X-ray image on a round-the-clock monitor or a notebook PC.

  Further, the round-the-clock monitor and the notebook PC generally do not correspond to the DICOM standard, which is exemplified by the Grayscale Standard Display Function (GSDF). Therefore, it is difficult to perform a highly accurate inspection using an X-ray image. As described above, the notebook PC attached to the round-trip monitor or the round-trip X-ray imaging apparatus often does not sufficiently satisfy the performance required to display a highly diagnostic X-ray image.

  Next, when a method for displaying X-ray image data on a medical image display monitor or the like from a roundtable X-ray imaging apparatus via a server, equipment such as a network environment or a medical image display monitor is required in the operating room. Therefore, in order to maintain the network environment etc., it is necessary to carry out the construction of the operating room in advance. Therefore, the method of transmitting image data to the server requires high cost and a long preparation period. Furthermore, it is difficult to say that it is preferable from the viewpoint of cleanliness that the operator or an assistant touch and operate the cable before and after the operation.

  Also, in the conventional example of transmitting and displaying on a monitor for medical image display via a server, after transmitting X-ray image data to a server, a target X-ray image data is transmitted from the server using a terminal in an operating room It needs to be sent to the display monitor. In addition to the target X-ray image data, a huge amount of data is accumulated from various places in the hospital on the server. Therefore, in addition to the problem that it takes a long time to select the target X-ray image data from the huge amount of data stored in the server, there is also a concern that there is a large risk of mistaken selection data.

  The present invention has been made in view of such circumstances, and enables X-ray images obtained by general radiography after surgery to be observed more quickly and in a highly diagnostic state. An object of the present invention is to provide a radiographic system, an X-ray imaging apparatus, and an X-ray detector.

FIG. 1 is a schematic view showing the configuration of the X-ray imaging system according to the first embodiment, and FIG. 2 is a functional block diagram for explaining the configuration of the X-ray imaging system according to the first embodiment.

<Description of Overall Configuration>
As shown in FIG. 1, the X-ray imaging system 1 according to the first embodiment includes a C-arm type X-ray imaging apparatus 11 and an X-ray imaging apparatus 101 for round examination. The circulation X-ray imaging apparatus 101 corresponds to a first X-ray imaging apparatus in the present invention, and the C-arm type X-ray imaging apparatus 11 corresponds to a second X-ray imaging apparatus in the present invention.

  The C-arm type X-ray imaging apparatus 11 is irradiated from an X-ray tube 15 for irradiating the subject M with an X-ray and an X-ray tube 5. And an X-ray detector 17 for detecting the X-ray and converting it into an electrical signal. The X-ray tube 15 and the X-ray detector 17 constitute an imaging system, and are disposed opposite to each other with the top plate 13 interposed therebetween. The X-ray detector 17 has a detection surface for detecting X-rays, and X-ray detection elements are two-dimensionally arranged on the detection surface. A flat panel detector (FPD) is used as an example of the X-ray detector 17.

  The X-ray tube 15 and the X-ray detector 17 are provided at one end and the other end of the C-arm 19 respectively. The C-arm 19 is held by the arm holding member 21 and is configured to slide along the arc path of the C-arm 19 indicated by reference numeral RA. The arm holding member 21 is disposed on the side surface of the support column 23, and can rotate around an axis of a horizontal axis RB parallel to the x direction (the longitudinal direction of the top 13 and the body axis direction of the subject M). Configured as. The C-arm 19 held by the arm holding member 21 pivots about an axis in the x direction according to the arm holding member 21.

  Since the X-ray detector 17 used in the C-arm type X-ray imaging apparatus 11 changes its position frequently according to the movement of the C-arm 19, it is necessary to consider the possibility of interference with the operator or the like. Therefore, the X-ray detector 17 used in the C-arm type X-ray imaging apparatus 11 is relatively small in size, for example, 9 to 10 inches square. In the first embodiment, a 9-inch square FPD is used as the X-ray detector 17.

  The columns 23 are supported by a support base 25 disposed on the floor surface, and are configured to be capable of horizontal movement in the y direction (the short direction of the top 3). The arm support member 21 and the C-arm 19 supported by the support 23 move in the y direction as the support 23 moves horizontally. The support base 25 is provided with wheels (not shown), and is configured to be movable in the x direction and the y direction. The collimator 27 is provided in the X-ray tube 15, and restricts the X-ray irradiated from the X-ray tube 15 to, for example, a fan-like fan angle θ.

  The C-arm type X-ray imaging apparatus 11 further includes a monitor carriage 29. The monitor carriage 29 is configured to be movable by the wheels 29a, and a medical monitor 31 is provided.

Further, the column 33 can be rotationally moved about the axis in the z direction, and the medical monitor 31 can appropriately change the direction in which the display screen faces as the column 33 rotates.

  The medical monitor 31 displays a medical image, for example, an X-ray image, for diagnosis and examination of the operator. Unlike the console panel 111, the medical monitor 31 is a high performance monitor for displaying a medical image. Therefore, the medical monitor 31 complies with the DICOM standard exemplified by GSDF, and has a display screen having a tone and resolution relatively higher than that of the console panel 111. The medical monitor 31 corresponds to the image display means in the present invention.

  The X-ray imaging apparatus for rounds 101 includes a carriage 103, a drive wheel 105, an auxiliary wheel 107, an operation handle 109, a console panel 111, a support 113, an extendable arm 115, an X-ray tube 117, and a collimator 119. Is equipped.

  One driving wheel 105 is provided on the left and right of the rear lower portion of the carriage 103. The carriage 103 advances and retracts according to the rotation of the drive wheel 105, and turns left and right due to the difference in rotational speed between the left and right drive wheels 105. The driving wheel 105 is configured to rotate by an electric motor provided inside the carriage 103.

  The auxiliary wheels 107 are provided one on each side of the front lower portion of the carriage 103 and turn left and right according to the turning direction of the carriage 103. The operation handle 109 is provided with a plurality of pressure sensors. The pressure sensor detects the pressure applied to the operating handle 109 when the operator grips the operating handle 109 to operate the carriage 103, and controls the rotational direction and rotational speed of the drive wheel 105.

  The console panel 111 is provided at the rear of the carriage 103 as an example, and includes an operation device for setting an X-ray imaging condition such as tube voltage and tube current, and a switch for X-ray imaging. The console panel 111 also has a function as a monitor (round monitor) that displays the X-ray image acquired by the round diagnosis X-ray imaging apparatus 101. Examples of the configuration of the console panel 111 include a touch input type panel and a keyboard input type panel.

  The support 113 is erected on the front portion of the carriage 103 and is configured to be rotatable around an axis in the z direction (around the vertical axis). A telescopic arm 115 is provided on the column 113. The telescopic arm 115 is configured to be slidable in the z direction along the support 113. The telescopic arm 115 is configured to be telescopic in the horizontal direction.

  An X-ray tube 117 is connected and held at the tip of the extendable arm 115. The X-ray tube 117 is configured to be rotatable around the axis of the extendable arm 115. Then, the X-ray tube 117 emits X-rays in accordance with the X-ray imaging conditions set in the console panel 111. The collimator 119 is provided at the lower part of the X-ray tube 117. The collimator 119 includes two pairs of movable limiting blades, and adjusts the irradiation field of the X-ray irradiated from the X-ray tube 117 by opening and closing each movable limiting blade.

  The round diagnosis X-ray imaging apparatus 101 further includes a storage unit 121. The storage unit 121 is provided at the rear of the carriage 103 as an example, and is configured to be able to store the X-ray detector 123 therein. On the X-ray detection surface of the X-ray detector 123, X-ray detection elements (not shown) are arranged in a two-dimensional matrix. Each of the X-ray detection elements is irradiated from the X-ray tube 115 to detect X-rays transmitted through the subject M. In the X-ray detector 123, the X-ray detected by the X-ray detection element is converted into an electrical signal and output as an X-ray detection signal. The X-ray detection element corresponds to the X-ray detection means in the present invention.

  Unlike the X-ray detector 17, the X-ray detector 123 used for the round-trip X-ray imaging apparatus 101 needs to consider little interference with the operator or the like. Therefore, the X-ray detector 123 is relatively large in size, for example, 14 to 17 inches square. In the first embodiment, a 17-inch square wireless FPD is used as the X-ray detector 123.

  Next, the configurations of the C-arm type X-ray imaging apparatus 11 and the round-table X-ray imaging apparatus 101 will be described in more detail. FIG. 2 is a functional block diagram for explaining the configuration of the C-arm type X-ray imaging apparatus 11 and the round-table X-ray imaging apparatus 101.

  The C-arm type X-ray imaging apparatus 11 further includes an X-ray irradiation control unit 35, an arm drive control unit 37, an image generation unit 39, an image information reception unit 41, and an input unit 43 in addition to the components shown in FIG. , A storage unit 45, and a main control unit 47. The X-ray irradiation control unit 35 is configured to apply a high voltage to the X-ray tube 15. Based on the high voltage output applied by the X-ray irradiation control unit 35, X-ray imaging conditions, for example, the X-ray dose irradiated by the X-ray tube 15 and the timing of X-ray irradiation are controlled.

  The arm drive control unit 37 controls the slide movement of the C-arm 19. By sliding the C-arm 19 in the direction indicated by the reference RA, the spatial position of each of the X-ray tube 15 and the X-ray detector 17 changes while maintaining the facing arrangement. Further, in addition to the slide movement of the C-arm 19, the arm drive control unit 37 integrally controls the rotational movement of the arm support member 21. Since the X-ray tube 15 and the X-ray detector 17 are provided on the C-arm 19, the spatial position of each changes while maintaining the facing arrangement according to the rotational movement of the arm support member 21.

  The image generation unit 39 is provided downstream of the X-ray detector 17 and generates an X-ray image of the subject M based on the X-ray detection signal output from the X-ray detector 17. The X-ray image is displayed on the large-screen medical monitor 31. Further, the medical monitor 31, which is a monitor for displaying a medical image, corresponds to each of the DICOM standards, and is configured such that the gradation and resolution of the display screen are relatively high. Therefore, the medical monitor 31 can suitably display a medical image such as an X-ray image. The image generation unit 39 corresponds to an image generation unit in the present invention.

  The image information receiving unit 41 is a characteristic feature of the C-arm type X-ray imaging apparatus 11 according to the first embodiment, and the information (data file) of the X-ray image transmitted from the image information transmitting unit 131 described later is P2P. Receive by communication according to the method. In the first embodiment, the image information receiving unit 41 receives X-ray image information by communication (P2P communication) using a P2P (Peer to Peer) method.

  In the first embodiment, the image information receiving unit 41 supports Wi-Fi Direct (registered trademark), and receives X-ray image information by P2P communication using Wi-Fi Direct. Further, the image information receiving unit 41 transmits the received X-ray image to the medical monitor 31 for display. As shown in FIG. 1 as one example, the image information receiving unit 41 is built in a monitor carriage 29 provided with a medical monitor 31. The image information receiving unit 41 corresponds to an image information receiving unit in the present invention.

  The input unit 43 is for inputting an instruction of the operator, and examples thereof include a keyboard input type panel provided on the monitor carriage 29, a touch input type panel and the like. The storage unit 45 stores information such as an X-ray image generated by the image generation unit 39 and an X-ray imaging condition set by the X-ray irradiation control unit 19. The main control unit 47 is configured by a central processing unit (CPU) or the like, and includes the medical monitor 31, the X-ray irradiation control unit 35, the arm drive control unit 37, the image generation unit 39, and the storage unit 45. Control the

  The circular imaging X-ray imaging apparatus 101 is provided with a CPU 125 inside the carriage 103. The CPU controls an X-ray irradiation control unit 127, an image generation unit 129, an image information transmission unit 131, a storage unit 133, and main control And a unit 135. The X-ray irradiation control unit 127 controls X-ray imaging conditions such as X-ray dose irradiated by the X-ray tube 105 and timing when the X-ray tube 105 irradiates X-rays.

  The image generation unit 129 generates an X-ray image of the subject M in general X-ray imaging after surgery based on the X-ray detection signal output from the X-ray detection element of the X-ray detector 123. The image generation unit 129 is not limited to the configuration provided in the CPU 125 in the carriage, and may be provided in the X-ray detector 123. The image generation unit 129 corresponds to an image generation unit in the present invention.

  Like the image information receiving unit 41, the image information transmitting unit 131 is a configuration characteristic of the round diagnosis X-ray imaging apparatus 101 according to the first embodiment. The image information transmission unit 131 directly transmits the information of the X-ray image generated by the image generation unit 129 to the image information reception unit 41. Transmission and reception of X-ray image information from the image information transmission unit 131 to the image information reception unit 41 is performed by communication (P2P communication) using a P2P method. In the first embodiment, the image information transmission unit 131 receives the information of the X-ray image using Wi-Fi Direct (registered trademark). The image information transmission unit 131 corresponds to an image information transmission unit in the present invention.

  The storage unit 133 stores information such as an X-ray image generated by the image generation unit 129 and an X-ray imaging condition set by the X-ray irradiation control unit 127. The main control unit 135 comprehensively controls the components such as the X-ray irradiation control unit 127, the image generation unit 129, the image information transmission unit 131, and the storage unit 133 according to the contents of the operator's instruction input to the console panel 111. Do.

<Description of operation>
Next, the operation of the X-ray imaging system 1 according to the first embodiment will be described. FIG. 3 is a flowchart for explaining the operation of the X-ray imaging system according to the embodiment. Here, a case where a general X-ray imaging is performed after a catheterization operation is performed will be described as an example.

Step S1 (Surgery with C-arm X-ray imaging apparatus)
First, as shown in FIG. 4, in the operating room A, surgery is performed using a C-arm type X-ray imaging apparatus. That is, the subject M is placed on the table-top 13, and the C-arm type X-ray imaging apparatus 11 is used to perform a catheterization operation. At the time of surgery, the operator operates the input unit 43 to appropriately displace the C-arm 19 and perform X-ray fluoroscopy. That is, the X-ray tube 15 is intermittently irradiated with the X-ray 15a from the X-ray tube 15 while the C-arm 19 is moved to appropriately displace the position of the X-ray tube 15.

  The X-ray detector 17 detects the X-ray 15a and outputs an X-ray detection signal. The image generation unit 39 generates an X-ray image (X-ray fluoroscopic image) by X-ray fluoroscopy based on the X-ray detection signal detected by the X-ray detector 17. The X-ray fluoroscopic image is displayed on the medical monitor 31 at any time through the main control unit 47, and the operator advances the surgical procedure while confirming the X-ray fluoroscopic image displayed on the medical monitor 31.

Step S2 (movement of X-ray imaging apparatus for rounds)
After the catheterization surgery is completed, it is necessary to perform general X-ray imaging on the subject M in order to examine the condition of the site where surgery has been performed. However, the X-ray detector 17 provided in the C-arm type X-ray imaging apparatus 11 has a small size of 9 inches square. Therefore, in order to perform general X-ray imaging using a larger sized X-ray detector, the operator uses the round-table X-ray imaging apparatus 101.

  In this case, the operator moves the C-arm type X-ray imaging apparatus 11 to a position away from the top 13, as shown in FIG. At this time, it is preferable to leave the monitor carriage 29 in the vicinity of the top 13. Then, the roundtable X-ray imaging apparatus 101 is placed in the operating room A and moved to the vicinity of the top 13. The positional relationship between the round-trip X-ray imaging apparatus 101, the C-arm type X-ray imaging apparatus 11, and the top 13 is not limited to the positional relationship shown in the front view of FIG. That is, as shown in the plan view according to FIG. 5B, the X-ray imaging apparatus for rounds X-ray imaging 101 performs X-ray general imaging in a state of being moved to the side of the subject M placed on the table 13. May be The operator N generally performs various operations while standing on the side of the top 13 as shown in FIG. 5 (b).

  Then, the operator rotates the support column 113 about the vertical axis and moves the X-ray tube 117 to the front of the round X-ray imaging apparatus 101. After the column 113 is rotated, the extendable arm 115 is vertically raised and the extendable arm 115 is extended horizontally to adjust the X-ray tube 117 to a position suitable for general X-ray imaging. After adjusting the position of the X-ray tube 117, the operator takes out the X-ray detector 123 from the storage portion 121 provided in the carriage 103, and as shown in FIG. Between the plate 13 and the X-ray detector 123 is installed.

Step S3 (X-ray general imaging by X-ray imaging apparatus for rounds)
After the X-ray detector 123 is installed, general X-ray imaging is started. That is, as shown in FIG. 6, the operator operates the console panel 111 to irradiate the subject M with the X-ray 117a from the X-ray tube 117. The X-ray 117 a emitted from the X-ray tube 117 to the subject M is detected by the X-ray detector 123 and converted into an X-ray detection signal.

  The image generation unit 129 generates an X-ray image of the subject M based on the X-ray detection signal output from the X-ray detector 123. Image information Da of the X-ray image is transmitted from the image generation unit 129 to the image information transmission unit 131 provided in the CPU 125. The image information Da of the X-ray image is transmitted from the image generation unit 129 to the storage unit 133 via the main control unit 135 in the CPU 125. The storage unit 133 stores the image information Da of the transmitted X-ray image.

Step S4 (transmission and reception of X-ray image)
After the general X-ray imaging is performed by the round diagnosis X-ray imaging apparatus 101, X-ray images are transmitted and received. That is, the image information transmission unit 131 provided in the round examination X-ray imaging apparatus 101 transmits the image information of the X-ray image to the image information reception unit 41 provided in the C-arm type X-ray imaging apparatus 11.

  As a feature of the present invention, transmission and reception from the image information transmission unit 131 to the image information reception unit 41 are performed by the P2P method. That is, the X-ray image (generally captured image) obtained by the X-ray general imaging is directly transmitted from the image information transmission unit 131 to the image information reception unit 41 by the function of Wi-Fi Direct.

  As shown in FIG. 7, the image information transmission unit 131 is provided in the CPU 125 built in the carriage 103, and the image information reception unit 41 is provided in the monitor carriage 29. Therefore, the information Da of the X-ray image generated in the X-ray imaging apparatus for rounds examination 101 is transmitted via the image information transmitting unit 131 in the CPU 125 and the image information receiving unit 41 in the monitor carriage 29 to a C-arm type X-ray imaging apparatus Sent to step 11.

  In the configuration according to the first embodiment, the information Da of the X-ray image is transferred between different X-ray imaging apparatuses (the X-ray imaging apparatus 101 for round visit and the C-arm type X-ray imaging apparatus 11 in the first embodiment) without the server. Transmit and receive directly by P2P method. In such a configuration, it is not necessary to search the data group in the server when specifying the information Da of the received X-ray image. Therefore, the image information receiving unit 41 can quickly specify and receive information Da of the target X-ray image.

Step S5 (Display of X-ray image)
The image information receiving unit 41 transmits information of the received X-ray image to the medical monitor 31 via the main control unit 47. The medical monitor 31 displays the transmitted X-ray image P as shown in FIG. Due to the structure of the carriage 103, the console panel 111 provided in the round diagnosis X-ray imaging apparatus 101 has a small screen size. Further, since the console panel 111 is not generally a display device dedicated to medical images, it does not correspond to each of the DICOM standards, and the gradation and resolution on the display screen are low.

  On the other hand, as the medical monitor 31 constituting the C-arm type X-ray imaging apparatus 11, generally, a high-performance display device dedicated to medical images is used. That is, the display screen of the medical monitor 31 corresponds to the DICOM standard such as GSDF, and the gradation and resolution are high. Therefore, since the X-ray image displayed on the medical monitor 31 is excellent in the visibility of the X-ray image, the operator can perform the examination after the operation more precisely by referring to the medical monitor 31. it can.

  The medical monitor 31 has a wide display screen, and can move up and down or rotate via the support 33. Therefore, the operator N can preferably observe the X-ray image captured on the medical monitor 31 without moving from the current position corresponding to the side of the top 13 as shown in FIG. 5B. Therefore, the time required for X-ray general imaging can be shortened and the burden on the operator can be reduced. By performing an examination after surgery with reference to the X-ray image displayed on the medical monitor 31, all the steps of the operation using the X-ray imaging system 1 are completed.

<The effect by the structure of Example 1>
Thus, the X-ray imaging system 1 according to the first embodiment transmits the X-ray image information by P2P communication, and the C-arm type X-ray receives the X-ray image information by P2P communication. It comprises the photographing device 11. Then, in the X-ray imaging system 1 according to the first embodiment, after X-ray general imaging is performed by the X-ray imaging apparatus for rounds examination to generate an X-ray image, the X-ray imaging apparatus for round examinations to C arm X-ray imaging apparatus by P2P communication Send X-ray image data to Then, the X-ray image transmitted by P2P communication is displayed on the monitor of the C-arm type X-ray imaging apparatus and used for examination after surgery.

  Since the round-trip X-ray imaging apparatus has a relatively large size X-ray detector, an X-ray image with a wider imaging range can be generated. On the other hand, since the C-arm type X-ray imaging apparatus has a relatively high-performance image display monitor, it is possible to display an X-ray image which enables more accurate inspection. As described above, in the first embodiment, X-ray image data is transmitted and received by P2P communication between different X-ray imaging apparatuses.

  Therefore, the advantage of one X-ray imaging apparatus that a wide range of X-ray images can be acquired by the round-table X-ray imaging apparatus 101 and the high diagnostic X-ray image can be displayed by the C-arm type X-ray imaging apparatus 11 The advantages of the other X-ray imaging apparatus can all be enjoyed. Further, since transmission and reception of X-ray image data between different X-ray imaging apparatuses is performed by P2P communication, the time required for transmission and reception of X-ray image data can be shortened. As a result, while reducing the burden on the operator and the subject, the accuracy of the examination in the general X-ray after surgery can be greatly improved.

  Here, the effects of the configuration according to the first embodiment will be described in more detail. When performing general X-ray imaging for examinations using a round-table X-ray imaging apparatus moved to the same operating room after performing surgery using a C-arm type X-ray imaging apparatus, it is obtained by X-ray general imaging There are the following three conventional methods for displaying X-ray images.

  The first method is to display on the console panel (monitor for rounds) provided on the trolley of the round-table X-ray imaging apparatus, and the second is connecting the notebook PC to the round-table X-ray imaging apparatus by wire or wirelessly This is a method of displaying on the screen of the terminal as an example. Then, as shown in FIG. 9 (a), the third is the X-ray imaging apparatus for round diagnosis within the operating room A, to the server in the hospital outside the operating room A, the data file Da of the X-ray image. It is a method of transmitting, and further transmitting a data file Da of an X-ray image from a server to a medical image display monitor installed in an operating room.

  However, in all of these conventional methods, there are concerns about the problem that it is difficult to perform an examination by X-ray general radiography after surgery precisely, and the problem that the time required for the examination by X-ray general radiography is prolonged Ru. That is, in general, in the round-table X-ray imaging apparatus, the size of the carriage is limited in order to avoid the decrease in the movement operability. Therefore, it is difficult to enlarge the display screen of the console panel provided in the round diagnosis X-ray imaging apparatus.

  Therefore, every time the operator N confirms the X-ray image P, as shown in FIG. 8A, from the position shown by the dotted line corresponding to the vicinity of the top 13, to the position shown by the solid line corresponding to the rear of the carriage 103. It is necessary to move and look into the small screen console panel 111. As a result, the examination of the X-ray image P becomes complicated, and the burden on the operator N increases.

  In general, a round-table X-ray imaging apparatus is an apparatus for performing X-ray imaging by moving to a patient's room where a patient is difficult to move. Therefore, in a general X-ray imaging apparatus for round-trip examinations, X-ray image data is returned to the operation room or the like from the patient's room without examining and displaying the X-ray image on the spot after X-ray imaging. Transfer to for inspection. Therefore, a display that has a relatively low gradation and resolution and does not conform to the standards such as DICOM necessary for displaying medical images suitably is often used as the display screen of the console panel. Therefore, when the first conventional method of displaying an X-ray image on the console panel is used, it is difficult to perform an examination after surgery precisely because the visibility and the diagnostic ability of the displayed X-ray image are low.

  The problem that it is difficult to carry out such an inspection accurately is also concerned in the second conventional method of displaying on the screen of a terminal such as a notebook PC. That is, in general, the display of a notebook PC is relatively small, and is not manufactured for use in displaying medical images. Therefore, as with the display screen of the console panel, the display screen of the notebook PC is small in size and low in gradation and resolution. Moreover, generally it does not correspond to DICOM specifications, such as GSDF.

  Therefore, even when an X-ray image is displayed by the second conventional method, there is a concern that precise post-operative examination becomes difficult because the visibility and diagnostic ability of the X-ray image is low. Also, in order for the operator N to confirm the X-ray image, the operator N moves near the notebook PC and looks into the display screen, or displays the notebook PC brought to another person such as an assistant Since it is necessary to look into the screen, inspection of a general photographed image becomes complicated.

  In contrast to the first and second conventional methods, the X-ray image is displayed on the medical image display monitor F installed in the operating room A in the third conventional method, so improvement in the diagnostic capability of the X-ray image is expected Be done. However, in the third conventional method, there are concerns about new problems such as an increase in the time required for inspection by X-ray general imaging.

  That is, in the third conventional method of transferring X-ray image information through the server S, as shown in FIG. 9, after performing surgery using the C-arm type X-ray imaging apparatus B in the operating room A, A general X-ray imaging is performed using the X-ray imaging apparatus K. In this case, the information of the generated X-ray image is first stored as a data file Da in the computer C (CPU) of the X-ray imaging apparatus for rounds X (see FIG. 9, reference R1). Next, the cable Ca is connected to the connector F, and the data file Da acquired by the round diagnosis X-ray imaging apparatus K is transmitted to the server S outside the operating room A via the network Ne (FIG. 9, symbol R2 reference).

  Then, in order to transmit the data file Da from the server S to the medical image display monitor Mo, a target data file Da is searched and selected from the data group in the server S at the terminal on the receiving side, that is, the medical image display monitor Mo See FIG. 9, reference R3). The data file Da selected last is transmitted from the server S to the medical image display monitor Mo, and the medical image display monitor Mo displays an X-ray image of the subject M based on the received data file Da (FIG. 9, Refer to code R4).

  Such a third conventional method requires that an environment for connecting the network Ne to the operating room and a medical image display monitor Mo connected to the server S via the network Ne be provided. However, the third conventional method can not often be used because the network environment is not prepared in the general operating room A. Further, even when the network environment is maintained, there is a concern that the process of connecting the cable Ca to the connector F and the process of transmitting the data file Da to the server S may be bothersome for the operator.

  Furthermore, in the server S, various data are accumulated from various places in the hospital besides the data file Da of the target X-ray image. Therefore, the operator is required to search and select the data file of the target X-ray image from the huge data group accumulated in the server S on the medical image display monitor F. Therefore, in the third conventional method, it takes a long time for the operator to search and select desired X-ray image information, and the burden on the operator increases. In addition, there is a concern that the time required for transferring X-ray image information may be further prolonged by causing a human error when searching for and selecting desired information from the information group stored in the server.

  On the other hand, the X-ray imaging system 1 according to the first embodiment has a configuration for transmitting and receiving data files of X-ray images between two X-ray imaging apparatuses. That is, the data file of the X-ray image acquired by the X-ray imaging apparatus 101 for round examinations which is one X-ray imaging apparatus is transmitted to the C-arm type X-ray imaging apparatus 11 which is the other X-ray imaging apparatus.

  In the X-ray imaging system 1, transmission and reception of data files between different X-ray imaging apparatuses are performed by P2P communication not via a server. That is, the image information transmission unit 131 is provided in the round examination X-ray imaging apparatus 101, and the image information receiving unit 41 is provided in the C-arm type X-ray imaging apparatus 11. The image information transmission unit 131 transmits X-ray image information by P2P communication, and the image information reception unit 41 receives X-ray image information by P2P communication.

  In the third conventional method, as shown in FIG. 9, the image data Da generated by the round-table X-ray imaging apparatus K is transmitted and displayed to the medical image display monitor Mo via the server S outside the operating room A. Ru. On the other hand, in the configuration according to the first embodiment, the data file Da of the X-ray image is directly transferred from the image information transmitting unit 131 to the image information receiving unit 41 without passing through the server (FIG. 2, FIG. 7).

  The server stores various data files in addition to the data file of the X-ray image. On the other hand, the CPU of the X-ray imaging apparatus constituting the X-ray imaging system rarely stores data files unrelated to the X-ray image. Therefore, in the first embodiment, in the C-arm type X-ray imaging apparatus 11 which is the X-ray imaging apparatus on the receiving side, the data file group to be searched for specifying the data file Da has the number of constituent data Very few compared to.

  Therefore, in the receiving X-ray imaging apparatus, the process of searching and selecting the data file of the target X-ray image from the huge data file group can be omitted, so the image information receiving unit 41 receives the transmitted X-ray image data. Files can be easily and quickly identified and received. As a result, in the X-ray imaging system according to the first embodiment, the time required for transferring X-ray image information between X-ray imaging apparatuses can be further shortened, and the data file of the X-ray image to be received is erroneously selected Can be avoided with certainty.

  Furthermore, since the X-ray imaging system according to the first embodiment has a configuration for transferring X-ray image information from the roundtable X-ray imaging apparatus 101 to the C-arm type X-ray imaging apparatus 11, general X-rays to be performed after surgery The examination by photographing can be performed more suitably. That is, the data file of the X-ray image acquired in the round-trip X-ray imaging apparatus 101 is transmitted from the image information transmitting unit 131 to the image information receiving unit 41 provided in the C-arm type X-ray imaging apparatus 11 by P2P communication. , And displayed on the medical monitor 31.

  Since the medical monitor 31 provided in the C-arm type X-ray imaging apparatus 11 is a monitor for displaying a medical image, it generally corresponds to the DICOM standard such as GSDF, and the display screen has a wide range of gradation and resolution Is high. Therefore, the operator N can observe the X-ray image displayed on the large-screen medical monitor 31 while being in the vicinity of the subject M placed on the top 13 as shown in FIG. The burden on the operator in the examination of X-ray images can be reduced. In addition, since the X-ray image displayed on the medical monitor 31 having high gradation and resolution is excellent in visibility and diagnostic ability, the operator can perform an examination after surgery more precisely.

  As described above, the X-ray imaging system according to the first embodiment has a configuration that can directly transmit and display the X-ray image acquired by the first X-ray imaging apparatus to the second X-ray imaging apparatus by P2P communication There is. In this case, even when the performance of the display device in the first X-ray imaging apparatus is low, X-ray image information is promptly transmitted to the second X-ray imaging apparatus having a high-performance display device, and the diagnostic ability is High X-ray image can be displayed. Therefore, in a situation where an examination by X-ray general radiography is performed after surgery, it is possible to greatly reduce the time required for the examination and to further improve the examination accuracy.

  Furthermore, in the X-ray imaging system according to the first embodiment, each of the image information transmission unit 131 and the image information reception unit 41 corresponds to Wi-Fi Direct (registered trademark). Wi-Fi Direct is a scheme that enables P2P communication without separately installing a router or access point. That is, by providing the image information transmitting unit 131 and the image information receiving unit 41 compatible with Wi-Fi Direct, the C-arm type X-ray imaging apparatus 11 constituting the X-ray imaging system 1 and the X-ray imaging apparatus 101 for round diagnosis In both cases, P2P communication is already possible.

  Therefore, when transferring X-ray image information by P2P communication using the X-ray imaging system according to the first embodiment, there is no need to perform in advance a construction for installing a router or an access point in the operating room. Therefore, in the first embodiment in which the X-ray image information is transferred by Wi-Fi Direct, it is possible to greatly reduce both the cost and time required in advance in order to perform the inspection of the general captured image with high accuracy.

  A second embodiment of the present invention will now be described with reference to the drawings. FIG. 10 is a functional block diagram for explaining the arrangement of an X-ray imaging system according to the second embodiment. Similar to the X-ray imaging system 1 according to the first embodiment, the X-ray imaging system 1A according to the second embodiment includes the circulation X-ray imaging apparatus 101A and the C-arm type X-ray imaging apparatus 11.

  However, in the circulation X-ray imaging apparatus 101 according to the first embodiment, the X-ray image transmission unit 131 is provided in the CPU 125 built in the cart 103. On the other hand, the round-table X-ray imaging apparatus 101A according to the second embodiment is different from the first embodiment in that the X-ray image transmission unit 131 is provided in the X-ray detector 123A.

  Similarly to the X-ray imaging apparatus for rounds X-ray imaging apparatus 101 according to the first embodiment, the round-table X-ray imaging apparatus 101A includes a cart 103, driving wheels 105, auxiliary wheels 107, operation handle 109, console panel 111, and columns 113. The telescopic arm 115, the X-ray tube 117, the collimator 119, and the storage portion 121 are provided. In the storage unit 121, an X-ray detector 123A is stored. The carriage 103 is provided with a CPU 125A, and the CPU 125A includes an X-ray irradiation control unit 127, a storage unit 133, and a main control unit 135.

  The X-ray detector 123A includes an X-ray detection unit 124, an image generation unit 129, and an image information transmission unit 131. The X-ray detection unit 124 detects an X-ray irradiated from the X-ray tube 117 and converts it into an X-ray detection signal which is an electric signal. An example of the X-ray detection unit 124 is an X-ray detection element arranged in a two-dimensional matrix on the X-ray detection surface of the X-ray detector 123A as in the first embodiment. The image generation unit 129 is provided downstream of the X-ray detection unit 124, and generates an X-ray image based on the X-ray detection signal output from the X-ray detection unit 124. The X-ray detection unit 124 corresponds to the X-ray detection means in the present invention.

  The image information transmission unit 131 transmits the information of the X-ray image generated by the image generation unit 129 to the image information reception unit 41 by the communication method using P2P. In the second embodiment, as in the first embodiment, the image information transmission unit 131 receives the information of the X-ray image using Wi-Fi Direct (registered trademark).

  The operation of the X-ray imaging system 1A according to the second embodiment is in common with the operation of the X-ray imaging system 1 according to the first embodiment. However, since the configuration in which the image information transmission unit 131 is provided is different, both of the steps S3 and S4 are different. Hereinafter, portions in which the operation according to the second embodiment differs from the operation according to the first embodiment will be described.
