Abstract
Abstract A radiation image recording and reproducing system comprises a recording section, a read-out section, a reproducing section, and a signal format converting section. The signal format converting section comprises a first buffer memory for storing the ID information giving specifics about a radiation image, which ID information is received from an external apparatus and has a first signal format, and a second buffer memory for storing the ID information, which has a second signal format adapted to the radiation image recording and reproducing system and into which the ID information having the first signal format was converted. A conversion table memory stores a conversion table. An operation device reads the ID information having the first signal format from the first buffer memory, converts the ID information, which has the first signal format and has been read out of the first buffer memory, into the ID information having the second signal format in accordance with the conversion table, and thereafter stores the ID information, which has the second signal format and has been generated during the conversion, in the second buffer memory.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
346 words
A radiation image recording and reproducing system, which comprises: i) an image recording section for irradiating radiation, which carries image information about an object, onto a stimulable phosphor sheet, a radiation image of the object being thereby stored on the stimulable phosphor sheet, ii) an image read-out section for exposing a stimulable phosphor sheet, on which a radiation image was stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to the radiation, the emitted light being detected and converted into an image signal, and iii) an image reproducing section for reproducing a visible image of a radiation image from an image signal, wherein the improvement comprises the provision of a signal format converting section for receiving ID information from an external apparatus, which ID information gives specifics about a radiation image and has a first signal format, and converting said ID information into ID information having a second signal format adapted to the radiation image recording and reproducing system, said signal format converting section comprising: a) a first buffer memory for storing the ID information, which is received from the external apparatus and has the first signal format, b) a second buffer memory for storing the ID information, which has the second signal format and into which the ID information having the first signal format was converted, c) a conversion table memory for storing a conversion table, which is used during the conversion of the ID information having the first signal format into the ID information having the second signal format, and d) an operation means for reading the ID information having the first signal format from said first buffer memory, converting the ID information, which has the first signal format and has been read out of said first buffer memory, into the ID information having the second signal format in accordance with said conversion table, and thereafter storing the ID information, which has the second signal format and has been generated during the conversion, in said second buffer memory.
Claim 2

A radiation image recording and reproducing system, which comprises: i) an image recording section for irradiating radiation, which carries image information about an object, onto a stimulable phosphor sheet, a radiation image of the object being thereby stored on the stimulable phosphor sheet, ii) an image read-out section for exposing a stimulable phosphor sheet, on which a radiation image was stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to the radiation, the emitted light being detected and converted into an image signal, and iii) an image reproducing section for reproducing a visible image of a radiation image from an image signal, wherein the improvement comprises the provision of a signal format converting section for receiving ID information from an external apparatus, which ID information gives specifics about a radiation image and has a first signal format, and converting said ID information into ID information having a second signal format adapted to the radiation image recording and reproducing system, said signal format converting section comprising: a) a first buffer memory for storing the ID information, which is received from the external apparatus and has the first signal format, b) a second buffer memory for storing the ID information, which has the second signal format and into which the ID information having the first signal format was converted, c) a conversion table memory for storing a conversion table, which is used during the conversion of the ID information having the first signal format into the ID information having the second signal format, and d) an operation means for reading the ID information having the first signal format from said first buffer memory, converting the ID information, which has the first signal format and has been read out of said first buffer memory, into the ID information having the second signal format in accordance with said conversion table, and thereafter storing the ID information, which has the second signal format and has been generated during the conversion, in said second buffer memory.
Claim 3
Dependent Claim
54 words
A system as defined in claim 1 wherein said signal format converting section works bilaterally such that it is capable of converting the ID information having the second signal format, which is adapted to the radiation image recording and reproducing system, into ID information having the first signal format adapted to an external apparatus.
Claim 4
Dependent Claim
31 words
A system as defined in claim 1 wherein said stimulable phosphor sheet, on which a radiation image was stored, is two-dimensionally scanned with said stimulating rays in said image read-out section.
Claim 5
Dependent Claim
15 words
A system as defined in claim 1 wherein said stimulating rays are a laser beam.
Claim 6
Dependent Claim
12 words
A system as defined in claim 1 wherein said radiation is X-rays.
Claim 7
Dependent Claim
36 words
A system as defined in claim 1 wherein an erasing section is provided for releasing any energy remaining on a stimulable phosphor sheet after an image signal has been obtained therefrom in said image read-out section.
