Abstract
Abstract A cassette of the kind used for holding sheets of film to be exposed during x-ray of a patient is coded so that an x-ray technician or operator can easily distinguish cassettes containing exposed film from those cassettes containing unexposed film. This is accomplished by color coding two adjacent side edges of the cassette with color different from the other side edges of the cassette.

137 words
A system for identifying when a cassette contains an exposed imaging element or an exposed imaging element, comprising: a cassette for holding an imaging element, said cassette having a first area of a first color and a second area of a second color, said first area being located on the cassette such that when the cassette is placed in a first position said first area of said first color will positioned so as to identify that an unexposed imaging element is disposed within the cassette and when the cassette is placed in a second position said second area of said second color will be positioned so as to identify that an exposed imaging element is disposed therein; and a bin having a plurality of slots for receiving said cassette in one of said first or second positions.
Claim 7
Independent Claim
127 words
A method of monitoring the status of a cassette containing an imaging element, comprising the steps of: providing a cassette having a first area of a first color and a second area of a second color, said first and second areas being placed on the cassette such that when said cassette is placed in a first position the first color will be positioned so as to identify that an unexposed imaging element is disposed within the cassette and when the cassette is placed in a second position said second area will be positioned so as to identify that an exposed imaging element is disposed therein; placing said in one of said two positions so as to identify whether the cassette contains an exposed or unexposed imaging element.
Claim 8
Independent Claim
127 words
A method of monitoring the status of a cassette containing an imaging element, comprising the steps of: providing a cassette having a first area of a first color and a second area of a second color, said first and second areas being placed on the cassette such that when said cassette is placed in a first position the first color will be positioned so as to identify that an unexposed imaging element is disposed within the cassette and when the cassette is placed in a second position said second area will be positioned so as to identify that an exposed imaging element is disposed therein; placing said in one of said two positions so as to identify whether the cassette contains an exposed or unexposed imaging element.
Claim 9
Dependent Claim
74 words
A cassette for holding an imaging element, a cassette having two different areas of two different colors such that when said cassette is placed in one of two different positions said first area of said first color will identify that the cassette contains an exposed imaging element and when the cassette is placed in said second position said second area of said second color will identify that the cassette contains an unexposed imaging element.
Claim 10
Dependent Claim
74 words
A cassette for holding an imaging element, a cassette having two different areas of two different colors such that when said cassette is placed in one of two different positions said first area of said first color will identify that the cassette contains an exposed imaging element and when the cassette is placed in said second position said second area of said second color will identify that the cassette contains an unexposed imaging element.
