MEDICAL DIGITAL RADIOGRAPHIC DEVICE, RADIOGRAPHIC SYSTEM, AND METHOD FOR IMAGING X-RAY FLUORESCENT IMAGE AS DIGITAL DATA

摘要

There are provided a medical digital radiographic device, a radiographic system, and a method for imaging X-ray fluorescent image as digital data. The radiographic device (10) includes: a fluorescent plate (38) for generating fluorescent light of image shape by X-ray radiation; a digital camera (42) for imaging the fluorescent light of the image shape from the fluorescent plate (38); and an X-ray shield material (40) arranged between the fluorescent plate (38) and the digital camera (42). The radiographic device (10)further includes a drive device (44) for changing the distance between the digital camera (42) and the fluorescent plate (38). The digital camera (42) performs imaging with a fixed magnification so that a medical image dimension is focused on the CCD with a predetermined resolution or above when the digital camera (42) is at the farthest position from the fluorescent plate (38).
