[Operation of the embodiment]
In the configuration as described above, when using the fluoroscopic imaging system 1000 of this embodiment, as shown in FIG. 2, an operator (not shown) places the chemical injection device 100 in the vicinity of the imaging unit 301 of the CT scanner 200. Then, a chemical syringe 400 and an extension tube (not shown) to be used are prepared.

  Therefore, the operator connects the chemical syringe 400 to a subject (not shown) located in the imaging unit 301 with an extension tube, and loads these chemical syringes 400 into the injection head 110 of the chemical injection device 100. In that case, the chemical syringe 400 is inserted into the recess 114 of the injection head 110 from above, and the cylinder member 410 is held by the cylinder holding mechanism 115 and the piston member 420 is held by the piston drive mechanism 116.

  In the state as described above, as shown in FIGS. 8 and 9, the operator inputs the imaging data to the CT scanner 200 with the operation panel 214 (step S1), and the operation panel 103 and the touch panel to the chemical solution injector 100. At 104, the injection data is input (step T1).

  Note that the imaging data input and operated as described above includes, for example, a work ID for each imaging operation, the name of the imaging device, personal data such as the name and weight of the subject, an imaging region, as shown in FIG. The infusion data is, for example, personal data such as the work ID for each infusion work, the name of the infusion device, the name and weight of the subject, as shown in FIG. 6 (b). , Consisting of text data such as the name of the drug solution and the name of the imaging region, but the work IDs of the imaging data and the injection data are set as common contents.

  Then, the CT scanner 200 is in a state where the input imaging data is temporarily stored in the RAM 213 and the imaging operation can be started (steps S2 and S3), and the chemical injection device 100 temporarily stores the input injection data in the RAM 133. The injection operation can be started by holding (steps T2 and T3).

  In this state, for example, when the operator inputs an injection start to the chemical liquid injector 100 using the operation panel 103 or the like (step T3), the chemical injector 100 is in communication with the CT scanner 200 and the computer apparatus 300. Confirm whether it is normal (step T4), and if it is not confirmed that the communication status is normal, "Cannot communicate with CT scanner / computer device. CT scanner / computer device is operating normally or communication cable is normal. Error guidance such as “Please confirm whether it is connected to” is displayed on the touch panel 104 (step T17).

  On the other hand, when it is confirmed that the communication state is normal (step T4), the chemical injection device 100 reads the temporarily stored injection data and drives the piston drive mechanism 116, so that this corresponds to the injection data. Then, a chemical solution such as a contrast medium for CT is injected from the chemical solution syringe 400 to the subject (step T6).

Then, a fluoroscopic image is taken corresponding to the imaging data from the subject into which the medicinal solution is injected (step S6).

  In the CT scanner 200, the captured fluoroscopic image is stored in the RAM 213 as bitmap data or the like (step S7). For example, when an end condition corresponding to the imaging data is detected (step S9), the operator captures the image. When the end is input to the operation panel 214 (step S10), the imaging operation is ended (step S11). Similarly, in the liquid injector 100, for example, when an end condition corresponding to the injection data is detected (step T8), or when the operator inputs an end of injection to the operation panel 103 or the like (step T9). The injection operation is finished (step T10).

  Then, in the CT scanner 200 that has finished the imaging operation as described above (step S11), the fluoroscopic image that has been stored is read out and given imaging data (steps S12 and S13), and this imaging data is given. The fluoroscopic image is transmitted from the I / F 216 to the drug solution injector 100 (step S14).

  At this time, because the data format of the fluoroscopic image made up of bitmap data and the like and the imaging data made up of text data are different, they are not combined as the same data, and the text data of the imaging data is attached to the bitmap data of the fluoroscopic image It becomes the state that was done.

  On the other hand, in the chemical injection device 100 that has completed the injection operation as described above (step T10), if the fluoroscopic image is not received by the predetermined time (steps T11 and T21), “the fluoroscopic image is not received”. Error guidance such as “Please check the CT scanner” is displayed on the touch panel 104 (step T22).

  Further, in the chemical solution injection device 100, when a fluoroscopic image is received before a predetermined time elapses (step T11), the work ID of the imaging data given to the fluoroscopic image and the work ID of the injection data are obtained. If the work IDs are not matched, error guidance such as “Work IDs do not match. Check the work IDs entered in the CT scanner and the chemical injection device” is displayed on the touch panel 104. The display is output (step T22).

  If the work IDs match (step T12), the text data of the injection data is also given to the fluoroscopic image (step T13). Next, as shown in FIG. 10, the duplication between the imaging data given to the fluoroscopic image and the injection data is detected (step T14), the data duplication is eliminated (step T15), and the imaging data and the injection data are detected. The data is synthesized (step T16).

  For example, as shown in FIG. 6A, the imaging data includes text data such as a work ID for each imaging operation, the name of the imaging device, personal data such as the name and weight of the subject, the name of the imaging part, and the imaging date and time. As shown in FIG. 6 (b), the injection data includes an operation ID for each injection operation, the name of the injection device, personal data such as the name and weight of the subject, the name of the medicinal solution, the name of the imaging part, etc. When composed of text data, the combined result of the imaging data and the injection data from which data duplication is eliminated is the work ID, the name of the imaging device, the name of the injection device, the name and weight of the subject, the name of the imaging part, the imaging date and time, The name of the chemical solution.

  Then, the text data resulting from the combination of the imaging data and the injection data from which data duplication is eliminated as described above is converted into image data such as bitmap data having the same format as the fluoroscopic image (step T17), and is shown in FIG. As described above, the image data is synthesized with the image data of the fluoroscopic image (step T18).

  Since the text data of the imaging data and the injection data is added as described above, and the fluoroscopic image data file in which the image data of the imaging data and the injection data is combined is transmitted from the chemical injection device 100 to the computer device 300. (Step T19) In this computer apparatus 300, as shown in FIG. 11, when the data file of the fluoroscopic image is received (step E1), the data file of the fluoroscopic image is stored in the HDD 304 or the like (step E2).

  When the fluoroscopic image is stored as described above, the computer device 300 is in a state where the fluoroscopic image can be browsed. Therefore, for example, when an operator inputs an operation ID or the like as a search key to the keyboard 308 (step E3), the search key is temporarily stored in the RAM 303 or the like (step E4), and display starts in this state. When an input operation is performed on the keyboard 308 (step E5), the fluoroscopic image is searched for data using the temporarily stored search key (step E6).

  At this time, since the fluoroscopic image is composed of bitmap data, data search cannot be performed directly with a search key composed of text data. However, since the fluoroscopic image is provided with imaging data composed of text data and injection data, these Is retrieved by the retrieval key, and the fluoroscopic image is retrieved.

  Therefore, if a fluoroscopic image is not searched for data (step E7), an error guidance such as “Image data not found. Check if search key is appropriate or image data is registered” is displayed on display 307. Displayed and output (step E12).

  On the other hand, when a fluoroscopic image is retrieved (step E7), the fluoroscopic image is read out and displayed on the display 307 (steps E8 and E9), so that the operator can view the desired fluoroscopic image. . At this time, it is possible to display and output the imaging data and the text data of the injection data given together with the bitmap data of the fluoroscopic image on the display 307. However, as shown in FIG. Since the text data with the data is combined with the image data of the fluoroscopic image as image data, the operator can check the imaging data and the injection data while browsing the fluoroscopic image.

[Effect of the embodiment]
In the fluoroscopic imaging system 1000 according to the present embodiment, when the fluoroscopic image captured by the CT scanner 200 is displayed and output together with the input imaging data by the computer device 300 as described above, the injection that is input to the chemical injection device 100 is input. Since the data is also displayed and output, the operator can check not only the imaging data but also the injection data when viewing the fluoroscopic image.

  Moreover, when the fluoroscopic image to which the imaging data is added is input from the CT scanner 200, the chemical injection device 100 adds the injection data to the computer image 300 and outputs it to the computer device 300. For this reason, the CT scanner 200 only needs to externally output the fluoroscopic image and the imaging data as in the conventional case, and the computer apparatus 300 may externally input the fluoroscopic image to which the text data has been added and display and output it. .

  That is, if the chemical injection device 100 of the present embodiment is interposed in the communication path between the conventional CT scanner 200 and the computer device 300, the fluoroscopic imaging system 1000 of the present embodiment is realized, so that it is not easy to replace on a large scale. Imaging data and injection data can be added to the fluoroscopic image while the CT scanner 200 and the computer apparatus 300 are used.

  In addition, a common work ID is set for the imaging data and the injection data, and the matching of the work ID is confirmed by the chemical injection device 100, and the injection data is given to the fluoroscopic image. It is prevented from being given. In particular, if the work IDs do not match, the chemical injection device 100 reports and outputs an error guidance, so that the operator can quickly confirm erroneous input of the work ID.

  In addition, since the imaging data and the injection data are converted into image data and combined with the fluoroscopic image, even if the text data of the imaging data and the injection data is not displayed and output, only the fluoroscopic image is displayed and output. Can also check imaging data and injection data. In particular, there are many portions where the imaging data and the injection data necessarily overlap, but the imaging data and the injection data are combined in a state where the data duplication is eliminated, so that sufficient imaging is necessary for the fluoroscopic image. Data and injection data can be combined.
