Abstracts Devices that acquire digital medical images using radiation (DR; Digital Radiography) are widely used in medical institutions to obtain information necessary for patient diagnosis. Compared to the existing film-sensitization method and computerized radiography system (CR, computed radiography system) method, digital medical imaging radiation generator has advantages such as image processing speed, diverse image parameters, image quality improvement through utilization, wide dynamic range, image post-processing method to remove noise from output instability, and artifact correction. This study was conducted to measure the 3-month cumulative dose of the radiation protection facility shielding wall of the radiation generating device that acquires digital medical images using a glass dosimeter for environmental monitoring, and to improve the diagnostic radiation safety management method by comparing it with foreign standards and to present it as basic data for education.
In this study, DK medical system Innovision (Ceiling Type - ELIN T5) was used to measure the radiation dose of the digital medical imaging radiation generator examination room protection wall [Figure 1]. Innovision device is a device that can quickly check a clear image with a low radiation dose and can be used easily and safely. This device is widely used as a device that supports conversion of standard medical images.
By selecting 3 hospitals that perform more than 50 digital X-ray medical imaging tests per day, a glass dosimeter for environmental measurement was installed outside the protection wall of the examination room, and the leakage radiation dose was measured for one month from May 16 to June 21, 2021.
The glass dosimeter was installed at 150 - 190cm from the floor considering the safety of the patient entrance and exit door, the entrance door of the digital medical image acquisition radiation generator control room, the shielding wall, and the patient viewing window based on the medical image X-ray examination room.
To measure and evaluate the shielding efficiency of the patient viewing window, multiple glass dosimeters were insta ... 전체 초록 보기
