Abstract
Abstract A cassette for use in a radiation image recording and readout system includes a radiation image storage panel including a layer of stimulable phosphor and having an identification recorded thereon, and a casing for enclosing the radiation image storage panel therein. The casing has an opening provided substantially in correspondence in position with the identification so as to sense it from the outside of the cassette. The identification may be recorded in a visual or magnetically sensable form.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A cassette for use in a radiation image recording and readout system comprising: a storage medium including a layer of stimulable phosphor for storing therein a latent image formed by an imagewise radiation, a layer of light absorbing material absorbing stimulative rays for said stimulable phosphor layer, and an identification provided on the layer of light absorbing material to be sensable for identifying said storage medium; and casing means for enclosing said storage medium therein, said casing means having two main surfaces, one of which transmits the imagewise radiation impinging thereon to the layer of stimulable phosphor, and the other of which opposes the layer of light absorbing material; said casing means having an opening provided in said other main surface substantially in correspondence in position with the identification so as to enable sensing of the identification through the opening from the outside of the cassette.
Claim 2
Dependent Claim
146 words
A cassette for use in a radiation image recording and readout system comprising: a storage medium including a layer of stimulable phosphor for storing therein a latent image formed by an imagewise radiation, a layer of light absorbing material absorbing stimulative rays for said stimulable phosphor layer, and an identification provided on the layer of light absorbing material to be sensable for identifying said storage medium; and casing means for enclosing said storage medium therein, said casing means having two main surfaces, one of which transmits the imagewise radiation impinging thereon to the layer of stimulable phosphor, and the other of which opposes the layer of light absorbing material; said casing means having an opening provided in said other main surface substantially in correspondence in position with the identification so as to enable sensing of the identification through the opening from the outside of the cassette.
Claim 3
Dependent Claim
19 words
A cassette in accordance with claim 1, wherein the identification on the storage medium is in a visual form.
Claim 4
Dependent Claim
23 words
A cassette in accordance with claim 1, wherein said storage medium comprises a magnetic recording medium on which the identification is magnetically recordable.
Claim 5
Dependent Claim
112 words
A cassette for use in a radiation image recording and readout system comprising: a radiation image storage panel including a first layer of stimulable phosphor, and a second layer of light absorbing material absorbing stimulative rays for the stimulable phosphor; a recording medium provided on one of the main surfaces of the second layer opposite to the first layer, and having an identification recorded thereon for identifying said storage panel; and casing means for enclosing said storage panel therein; said casing means having an opening provided substantially in correspondence in position with said recording medium so as to enable sensing of the identification through the opening from the outside of the cassette.
Claim 6
Dependent Claim
112 words
A cassette for use in a radiation image recording and readout system comprising: a radiation image storage panel including a first layer of stimulable phosphor, and a second layer of light absorbing material absorbing stimulative rays for the stimulable phosphor; a recording medium provided on one of the main surfaces of the second layer opposite to the first layer, and having an identification recorded thereon for identifying said storage panel; and casing means for enclosing said storage panel therein; said casing means having an opening provided substantially in correspondence in position with said recording medium so as to enable sensing of the identification through the opening from the outside of the cassette.
Claim 7
Dependent Claim
18 words
A cassette in accordance with claim 4, wherein the identification on the recording medium is a visual form.
Claim 8
Dependent Claim
23 words
A cassette in accordance with claim 4, wherein said recording medium comprises a magnetic recording substance on which the identification is magnetically recordable.
