A control signal is output from the main controller 109 to the X-ray tube controller 107 and the rotating body controller 108. The main controller 109 sends control signals to each part of the gantry 100 and the table device 200 in addition to the X-ray tube controller 107 and the rotating body controller 108 so that imaging (scanning) is performed under predetermined imaging conditions. It is designed to output.

  Furthermore, the gantry 100 is provided with a display unit 110 for displaying various information.

  The gantry 100 is provided with a USB port 111. The main controller 109 includes a reading unit 1091 that reads information in the USB memory device 400 connected to the USB port 111. Specifically, the reading unit 1091 reads at least information (to be described later) to be displayed at the time of examination among specific information about the patient stored in the USB memory device 400. The reading unit 1091 is an example of an embodiment of reading means in the present invention.

  In this example, the reading unit 1091 also reads a fingerprint verification result in a biometric authentication unit 4011 (to be described later) of the USB memory device 400.

  The configuration of the USB memory device 400 will be described with reference to FIG. The USB memory device 400 is an example of an embodiment of an external storage medium according to the present invention, and includes a control unit 401, a memory unit 402, a fingerprint sensor 403, and a USB interface 404.

  The memory unit 402 stores unique information about the patient. Specific information regarding the patient includes patient information displayed in the examination in the medical image diagnostic apparatus. The patient information displayed in the examination stored in the memory unit 402 is information that is not necessarily input by the examiner on the operation console 300 in the examination room. In this example, as information about the patient, information such as the patient's name, sex, age, weight, and height, which is initial input information input before inputting imaging conditions in the conventional examination procedure, is stored in the memory unit. 402. In this example, these pieces of information (hereinafter referred to as “initial input information”) are read by the reading unit 1091 and displayed on the display device 303 described later of the operation console 300.

  The memory unit 402 also stores patient biometric information as information specific to the patient. In this example, patient fingerprint data is stored as the biometric information. Incidentally, the fingerprint sensor 403 is an example of an embodiment of detection means for detecting biological information of a patient.

  The control unit 401 includes a biometric authentication unit 4011 that collates the fingerprint read by the fingerprint sensor 403 with the fingerprint stored in the memory unit 402. In addition, the control unit 401 outputs the collation result in the biometric authentication unit 4011 to the reading unit 1091, and also outputs initial input information stored in the memory unit 402 to the reading unit 1091. It is supposed to be. An output signal from the control unit 401 is output to the reading unit 1091 through the USB port 111 by the USB interface 404. The initial input information and the fingerprint collation result input to the reading unit 1091 are output to a central processing unit 301 (to be described later) of the operation console 300. The main controller 109 displays the fingerprint collation result input to the reading unit 1091 on the display unit 110.

  As shown in FIG. 1, the table apparatus 200 includes a top plate 202 slidably provided on a base 201, and a patient is placed on the top plate 202 and conveyed to the gantry 100. . The table device 200 is controlled by receiving a control signal from the main controller 109.

  The operation console 300 includes a central processing unit 301 that controls the entire apparatus, an input device 302 such as a keyboard that receives input from an operator, and a display that displays a tomographic image reconstructed by the central processing unit 301. An apparatus 303 includes a storage device 304 that stores programs, data, data, X-ray tomographic images, and the like.

  The central processing unit 301 causes the display device 303 to display initial input information output from the main controller 109 of the gantry 100 and a fingerprint collation result. However, in the present invention, the notifying means for notifying the fingerprint collation result is not limited to the display device 303 or the display unit 110. For example, whether or not the patient himself / herself is a voice is displayed on the operation console 300. You may make it inform by.

  Now, a flow when performing inspection using the X-ray CT system 1 will be described. FIG. 4 is a flowchart when performing an inspection using the X-ray CT system 1 of this example. As shown in FIG. 4, when performing an examination using the X-ray CT system 1, first, in step S1, the USB memory device 400 stores the initial input information and the patient's fingerprint. The process of step S1 is performed in a place different from the examination room in which the X-ray CT apparatus 2 is installed. Specifically, the initial input information is input by connecting the USB memory device 400 to a personal computer or the like placed in a place different from the examination room, and stored in the memory unit 402. As for fingerprint data, the fingerprint sensor 403 reads the patient's fingerprint and stores it in the memory unit 402.

  Next, in step S2, the patient moves to the examination room where the X-ray CT apparatus 2 is installed with the USB memory device 400 and undergoes examination. When the inspection is completed, the USB memory device 400 is returned to the reception in step S3.

  The inspection process in step S2 will be described with reference to FIG. FIG. 5 is a flowchart of an inspection procedure in the X-ray CT apparatus system 1 of this example. As shown in FIG. 5, first, in step S 21, the USB memory device 400 is inserted into the USB port 111. Next, in step S22, the identity of the patient is confirmed. Specifically, when the patient first places a finger on the fingerprint sensor 403, the fingerprint sensor 403 reads the fingerprint. Then, the biometric authentication unit 4011 of the control unit 401 collates the fingerprint read by the fingerprint sensor 403 with the fingerprint stored in the memory unit 402. A coincidence signal is output to the reading unit 1091 of the gantry 100. On the other hand, if they do not coincide, a mismatch signal is output to the reading unit 1091.

  Here, the fingerprint verification by the biometric authentication unit 4011 may be performed before the USB memory device 400 is inserted into the USB port 111. For example, when the patient holds the USB memory device 400 in his / her hand in order to insert the USB memory device 400 into the USB port 111, the fingerprint may be read by the fingerprint sensor 403 and collation of the fingerprint may be performed. In this way, prompt biometric authentication is performed, which leads to an improvement in the inspection workflow.

  The main controller 109 outputs the coincidence signal or the disagreement signal input to the reading unit 1091 to the central processing unit 301. When the coincidence signal is input, the central processing unit 301 displays a display indicating that the patient is the patient on the display device 303. On the other hand, when a mismatch signal is input, the central processing unit 301 causes the display device 303 to display a display indicating that the person is different from the patient.

  When the coincidence signal is input to the reading unit 1091, the main controller 109 causes the display unit 110 to display a display indicating that the patient is the same as the display device 303 of the operation console 300. . Thereby, it can be confirmed reliably and easily whether it is a patient himself / herself. In addition, when a mismatch signal is input to the reading unit 1091, the main controller 109 displays a display indicating that the person is different from the patient on the display unit 110. In this way, in addition to the display device 303 of the operation console 300, the fingerprint comparison result is displayed on the display unit 110 of the gantry 100, so that the person who works near the gantry 100 is also the patient himself / herself. You can check whether or not.

  In step S22, when the collation result by the biometric authentication unit 4011 is coincident (in the case of the patient himself), the process proceeds to step S23. On the other hand, if the collation result by the biometric authentication unit 4011 does not match in step S22 (if it is not the patient himself), the examination is stopped and the process proceeds to step S3.

  When the coincidence signal is input from the biometric authentication unit 4011, the reading unit 1091 reads the initial input information from the USB memory device 400 in step S23. The initial input information is output to the central processing unit 301 and displayed on the display device 303 and stored in the storage device 304.

  Here, the reading unit 1091 reads the initial input information from the USB memory device 400 in advance, and only when the coincidence signal is input from the biometric authentication unit 4011, the initial input information is stored in the central processing unit. It may be output to 301.

  Next, in step S24, a scan start position, a scan end position, a gantry rotation speed, a table moving speed, a slice thickness, a tube voltage, and the like are input from the input device 302 of the operation console 300 as imaging conditions. In step S25, an image is taken (scanned) to obtain a tomographic image.

  Incidentally, the obtained tomographic image may be stored in the memory unit 402 of the USB memory device 400. The memory unit 402 may store a medical examination result (medical chart information) performed by a doctor separately from the examination. By doing in this way, the information regarding a patient can be collectively managed by the USB memory device 400 from examination to examination.

  According to the X-ray CT system 1 of this example described above, the biometric information detected by the fingerprint sensor 403 of the USB memory device 400 by the biometric authentication unit 4011 is the biometric information stored in the memory unit 402. By checking, it can be confirmed surely and easily whether or not the patient. In addition, when the collation result by the biometric authentication unit 4011 matches, unique information regarding the patient read by the reading unit 1091 is displayed, so that it is possible to save time for the examiner to manually input such information. . Thereby, the workflow at the time of inspection can be improved.

  Next, a modification of the above embodiment will be described. First, the first modification will be described. A face image of a patient may be stored in the memory unit 402 of the USB memory device 400. In this case, when the USB memory device 400 is connected to the USB port 111, the reading unit 1091 reads a face image stored in the memory unit 402 and displays it on the display unit 110. In addition, the face image read by the reading unit 1091 is output from the main controller 109 to the central processing unit 301 of the operation console 300. The central processing unit 301 causes the display device 303 to display the face image input from the main controller 109. Thus, by displaying the patient's face image on the display unit 110 and the display device 303, it is possible to confirm whether or not the patient is the patient himself / herself reliably and easily.

  Next, a second modification will be described. In the second modification, the imaging condition of the patient set by the examiner may be stored in the memory unit 402 of the USB memory device 400. This imaging condition is a condition set by the inspector on the operation console 300 at the time of past inspection. Specifically, the storage of the shooting conditions in the memory unit 402 will be described. When the inspector inputs imaging conditions from the input device 302 of the operation console 300, the imaging conditions are output from the central processing unit 301 to the main controller 109. The shooting conditions input to the main controller 109 are output to the USB memory device 400 and written to the memory unit 402.

  When a patient who has been examined in the past is examined again under the same imaging conditions, imaging is performed using the imaging conditions stored in the USB memory device 400. Specifically, when the USB memory device 400 is connected to the USB port 111, the reading unit 1091 reads the shooting conditions stored in the memory unit 402. The main controller 109 outputs a control signal to each unit so that shooting is performed under the read shooting conditions. In the present invention, the main controller 109 is an example of an embodiment of a control unit that controls shooting under shooting conditions stored in an external storage medium.

  Here, the reading unit 1091 may read the imaging condition when the fingerprint collation result by the biometric authentication unit 4011 matches.

  According to the second modification, when photographing is performed under the same photographing conditions as in the past inspection, it is not necessary to input the photographing conditions again, and the inspection procedure can be further simplified.

  Next, a third modification will be described. In the above description, the USB memory device 400 includes the biometric authentication unit 4011 that collates the fingerprint read by the fingerprint sensor 403 with the fingerprint stored in the memory unit 402. The biometric authentication means is not limited to being provided in the USB memory device, and the biometric authentication unit 4011 may be provided on the X-ray CT apparatus 2 side, although not particularly illustrated. For example, the main controller 109 of the gantry 100 or the central processing unit 301 of the operation console 300 may include a biometric authentication unit. In this case, when the fingerprint data detected by the fingerprint sensor 403 and the fingerprint data stored in the memory unit 402 are input from the USB memory device 400, the biometric authentication unit performs the same as described above. The two are collated, and the collation result is output. Even in this case, the reading unit 1091 reads the initial input information stored in the USB memory device 400 when the collation result by the biometric authentication unit matches. Alternatively, the initial input information is output to the central processing unit 301 and displayed on the display device 303 only when the initial input information is read in advance by the reading unit 1091 and the collation result is coincident. It may come to be.

  In the present invention, the detection means for detecting the patient's biological information is not limited to being provided in the USB memory device. For example, although not particularly illustrated, the biometric authentication unit 4011 may be provided on the X-ray CT apparatus 2 side, and the fingerprint sensor 403 may also be provided on the X-ray CT apparatus 2 side. In this case, the reading unit 1091 reads fingerprint data stored in the USB memory device 400 and collates this data with fingerprint data detected by the fingerprint sensor in the biometric authentication unit.

  The present invention has been described above with reference to the above embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. For example, the present invention can be applied to a medical image diagnostic system using an MRI apparatus and a medical image diagnostic system using an ultrasonic diagnostic apparatus.

  In addition, the patient's biological information is a fingerprint in the above embodiment, but the present invention is not limited to this, and may be, for example, a patient's voiceprint or a retina pattern. When the patient's biometric information is other than the fingerprint, the USB memory device 400 may include a sensor that detects a voiceprint or a retina pattern as a detection unit that detects biometric information instead of the fingerprint sensor 403.

  Further, the USB port 111 and the reading unit 1091 are provided in the gantry 100 in the above embodiment, but the present invention is not limited to this, and may be provided in the operation console 300, for example. .

  In the above embodiment, the USB memory device is described as an example of the external storage medium. However, the external storage medium in the present invention is not limited to this, and may be, for example, an IC tag or an IC card. .
