Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 words
A scanner assembly comprising a support head, a C-shaped gantry, means for supporting said gantry in said support head for rotating movement, an x-ray source mounted on one side of said gantry for independent movement with respect to a detector array along said gantry, said x-ray source projecting x-rays across said gantry, and a detector array mounted on the other side of a gantry for independent movement with respect to said x-ray source along said gantry, said detector array serving to receive said projected x-rays.
Claim 2
Dependent Claim
85 words
A scanner assembly comprising a support head, a C-shaped gantry, means for supporting said gantry in said support head for rotating movement, an x-ray source mounted on one side of said gantry for independent movement with respect to a detector array along said gantry, said x-ray source projecting x-rays across said gantry, and a detector array mounted on the other side of a gantry for independent movement with respect to said x-ray source along said gantry, said detector array serving to receive said projected x-rays.
Claim 3
Dependent Claim
31 words
A scanner as in claim 1 including head support means for rotatably mounting said support head for rotation about an axis which is perpendicular to a rotational axis of said gantry.
Claim 4
Dependent Claim
33 words
A scanner as in claim 2 including means for mounting said head support for moving and positioning said support head whereby the gantry is placed in cooperative relationship with an object being scanned.
