Abstract
In a radiation image recording system in which a radiation image is once recorded on a stimulable phosphor sheet and then read out and reproduced into a visible radiation image, a high-power light source is built in the system to erase the noise due to the previously stored radiation image and the fog in the phosphor sheet by a single erasing operation immediately before the phosphor sheet is to be used to record thereon a radiation image. The light source has an exposure amount of at least 500,000 1x.multidot.sec. and is positioned between a phosphor sheet feeding section and a section where a radiation image is recorded on the sheet. The system is also provided with a mechanism for sending the phosphor sheet from the recording section to a sheet receiver or radiation image read out and reproducing apparatus.
Claims14
A radiation image recording system comprising:
- (a) a container means for containing stimulable phosphor sheets or a continuous stimulable phosphor sheet used for radiation image recording and reproduction;
- (b) a stimulable phosphor sheet supplying means for supplying each said stimulable phosphor sheet or predetermined lengths of said continuous phosphor sheet from said container means to a recording position;
- (c) a stimulable phosphor sheet holding means for holding said stimulable phosphor sheet in said recording position;
- (d) a sheet delivery means for ejecting said stimulable phosphor sheet from said recording position after a radiation image is recorded on said stimulable phosphor sheet and for delivering it to a sheet receiving section or a radiation image information read out and reproducing system;
- (e) an irradiation means which is provided between said container means and said stimulable phosphor sheet holding means for erasing noise in said stimulable phosphor sheet, said irradiation means having an exposure amount of 500,000 1x.multidot.sec. or more.
