Claims
- 1. A radiation image recording and read-out apparatus, comprising:
- (i) a circulation and conveyance means for conveying a plurality of stimulable phosphor sheets for recording a radiation image thereon along a predetermined circulation path;
- (ii) an image recording section positioned on said circulation path for recording a radiation image of an object on each of said stimulable phosphor sheets by exposing said stimulable phosphor sheets to a radiation passing through said object;
- (iii) an image read-out section positioned on said circulation path and provided with a stimulating ray source for emitting stimulating rays for scanning each of said stimulable phosphor sheets carrying said radiation image stored thereon at image recording section and a photoelectric read-out means for detecting light emitted by said stimulable phosphor sheet scanned by said stimulating rays to obtain an electric image signal;
- (iv) an erasing section positioned on said circulation path for, prior to the next image recording on said stimulable phosphor sheets for which the image read-out has been conducted at said image read-out section, having said stimulable phosphor sheets release the radiation energy remaining on said stimulable phosphor sheets;
- a control section including storage means for storing image recording menus representing the portion of the object to be recorded with corresponding stimulating ray scanning sizes;
- means for receiving a signal representing one of said image recording menus;
- reading means for reading the scanning size corresponding to said image recording menu represented by said signal from said storage means; and
- means for sending a signal representing said scanning size to said image read-out section, wherein
- said image read-out section includes means for adjusting said stimulating ray scanning size in response to said scanning size signal such that said stimulating ray scans a portion of said stimulable phosphor sheet corresponding to said scanning size signal.
- 2. An apparatus as defined in claim 1 wherein said image read-out section comprises alight deflector for scanning said stimulating rays on said stimulable phosphor sheet in a main scanning direction, and a sheet movement means for moving said stimulable phosphor sheet in a sub-scanning direction while said stimulable phosphor sheet is scanned with said stimulating rays in the main scanning direction.
- 3. An apparatus as defined in claim 2 wherein said image read-out section is constituted to change said stimulating ray scanning size with respect to said stimulable phosphor sheet by controlling the operations of said light deflector and said sheet movement means.
- 4. An apparatus as defined in claim 1, 2 or 3 wherein said image recording section is provided with marks corresponding to said stimulating ray scanning sizes.
- 5. The radiation image recording and read-out apparatus of claim 1, wherein said image recording section includes an irradiation field adjusting means for adjusting an irradiation field to a region on said stimulable phosphor sheet where said scanning with said stimulating rays is conducted.
- 6. An apparatus as defined in claim 5 wherein said image read-out section comprises a light deflector for scanning said stimulating rays on said stimulable phosphor sheet in a main scanning direction, and a sheet movement means for moving said stimulable phosphor sheet in a sub-scanning direction while said stimulable phosphor sheet is scanned with said stimulating rays in the main scanning direction.
- 7. An apparatus as defined in claim 6 wherein said image read-out section is constituted to change said stimulating ray scanning size with respect to said stimulable phosphor sheet by controlling the operations of said light deflector and said sheet movement means.
- 8. An apparatus as defined in claim 5 wherein said image recording section is provided with a means for moving a radiation source for emitting said radiation.
- 9. An apparatus as defined in claim 8 wherein said control section sends said scanning size designation signal also to said radiation source moving means and said irradiation field adjusting means.
- 10. An apparatus as defined in claim 9 wherein said image read-out section is constituted to change a starting point of said scanning in accordance with said scanning size.
