In medical examinations using X-rays, especially medical examinations using a CT scanning device, a certain amount of X-ray dose is necessary because of the relationship with the image quality of the captured image. Therefore, it is necessary to strictly manage the annual X-ray exposure in medical examinations.

However, the system described in Patent Document 1 cannot manage exposure information and image quality information in medical examinations. For this reason, in each medical institution that performs a medical examination using a CT scanning device or the like, the image quality of the captured image based on the experience of the administrator of each medical examination device can be obtained only by using each information provided from the system described in Patent Document 1. However, it was not possible to obtain information that can capture an image with sufficient image quality for screening while suppressing the exposure dose to some extent.

Therefore, the present invention has been made in view of the above problems, and by uniformly managing exposure information and image quality information in a medical examination using a CT scan device or the like, it is possible to capture a uniform image quality image.

(Features of the management system 100)
In a medical facility having the CT scanning device 10, the information providing terminal 20, and the browsing terminal 30, the management system 100 uses the CT scanning device 10 of the own facility and data of the highest image quality of the captured image (each manufacturer). (Including the latest device data) can always be known. Therefore, it is possible to quantitatively grasp the image quality of the image taken by the CT scanning device 10 of the own facility and the exposure amount of the phantom and the subject. As a result, it can be used to determine the validity of the imaging conditions of the CT scanning apparatus 10 at the own facility.

Further, in a medical facility having the CT scan device 10, the information providing terminal 20, and the browsing terminal 30, the management system 100 always knows the CNR evaluation result of the medical facility having the other CT scan device 10. be able to. Therefore, the CNR evaluation result in the CT scan apparatus 10 of the own facility can be quantitatively compared with a medical facility having another CT scan apparatus 10. In particular, if the text data includes, for example, the data of which manufacturer's CT scan device of which model number and which software (including version information), the CNR in the CT scan device 10 of the own facility. The evaluation result can be compared with the CNR evaluation result in another CT scanning apparatus 10 using the same manufacturer and the same software. As a result, for example, it is possible to specifically grasp which part (pulmonary apex, tracheal bifurcation, lung bottom, etc.) is good or bad in the lungs, so that the problem part can be grasped.

In addition, by using a common phantom in a medical facility having the management system 100 and storing the data in the server 50, the data can be browsed by the browsing terminal 30 mutually. This can be used as a reference for setting the CT scan apparatus 10 in the facility.

As described above, according to the management system 100 of the present embodiment, by managing the exposure information and the image quality information in the medical examination using the CT scan device 10, it is possible to uniformly capture an image with a constant image quality. It is possible to provide information to users (users) and to strictly manage the annual exposure dose of each examinee. Further, in the visual evaluation terminal 40, when the user wants to browse the text data with a relatively small amount of data by separating the web browser 41 and the image reference web browser 42, the web browser 41 is used to display an image with a large amount of data. By browsing the data with the image reference Web browser 42 only when necessary, it is possible to make the computer perform faster processing.

The embodiments of the present invention have been described above, but only specific examples are illustrated, and the present invention is not particularly limited. The specific configuration and the like can be appropriately changed in design. Further, the actions and effects described in the embodiments of the invention only list the most preferable actions and effects resulting from the present invention, and the actions and effects according to the present invention are described in the embodiments of the present invention. It is not limited to what was done.

For example, the information providing terminal 20 may have the function of the browsing terminal 30 together. Thereby, since the number of terminals can be reduced, cost can be reduced.

Further, when the data obtained by the CT scanning device 10 is stored in the first data storage unit 51 of the server 50 of the management system 100 via the information providing terminal 20, the user of the visual evaluation terminal 40 (for example, an image) A server 50 may be provided with a mail automatic transmission unit that automatically transmits a visual evaluation request mail to a diagnostician, a medical worker (expert) who has specialized knowledge, or has passed a certification examination. Further, in this automatic mail sending unit, the data obtained by the CT scanning device 10 is stored in the second data storage unit 52 of the server 50 of the management system 100 via the information providing terminal 20 and is stored in the browsing terminal 30. When browsing is possible, a function of sending a public notice mail to the information providing terminal 20 may be added.

In addition, the first website and the second website displayed on the browsing terminal 30 include the device model (model number) and software installed in the device by the first website construction unit 55 and the second website construction unit 53. It is also possible to extract and display only the data obtained from the CT scan apparatus 10 of another organization whose version matches.

In the system 100 of the above embodiment, the data automatically acquired from the CT scan apparatus 10 at the information providing terminal 20 is automatically transmitted to the server 20. However, the data is manually extracted from the CT scan apparatus 10 and stored in the memory. The data is stored in a storage medium such as the server, and the medium is sent to the administrator of the server 20 or sent by mail, and then the administrator appropriately reads data into the first data storage unit and the second data storage unit. It may be allowed.

Further, the first website construction unit 55 or the second website construction unit 53 allows the browsing terminal 30 to check whether the visual evaluation or CNR evaluation of the image data transmitted from the information providing terminal 20 has been completed. A page indicating whether visual evaluation or CNR evaluation of each image data has been completed may be constructed on the first website or the second website.

In addition, the program may be configured so that the first Web site and the second Web site can be browsed within the same Web site so that they can be viewed on a single web browser at the browsing terminal.
