Abstract
Abstract A curved beam apparatus adapted for mounting thereon a scintillation detector. The apparatus comprises a circular C-arm which is balanced with a counterweight at one end and a scintillation detector pivotally mounted by means of a yoke at the other end. The C-arm is mounted in a carrier member which in turn is attached to a base. The carrier member is rotatable about an axis passing through its center. In addition, the C-arm rotates circumferentially along a plane defined by the shape of the C-arm and intersecting said axis. The combination of the rotation of the C-arm and the rotation of the carrier member permits the scintillation detector to be quickly and easily manually positioned to any desired location on an imaginary sphere surrounding a portion of patient to be examined.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
A curved beam apparatus for supporting and positioning a scintillation detector to a desirable location relative to a patient which comprises: a) a generally C-shaped support member including means for pivotally supporting said scintillation detector at one end portion thereof; b) a carrier member for retaining said support member and for permitting orbital movement of said support member along a predetermined planar arcuate path defined by the shape of said support member; c) means for moving said support member along said arcuate path; and d) a base member for rotatably supporting said carrier member and for permitting said carrier member and hence said support member axial rotation.
Claim 2
Dependent Claim
107 words
A curved beam apparatus for supporting and positioning a scintillation detector to a desirable location relative to a patient which comprises: a) a generally C-shaped support member including means for pivotally supporting said scintillation detector at one end portion thereof; b) a carrier member for retaining said support member and for permitting orbital movement of said support member along a predetermined planar arcuate path defined by the shape of said support member; c) means for moving said support member along said arcuate path; and d) a base member for rotatably supporting said carrier member and for permitting said carrier member and hence said support member axial rotation.
Claim 3
Dependent Claim
27 words
A curved beam apparatus in accordance with Claim 1 wherein said means for moving said support member includes a rack and pinion disposed within said carrier member.
Claim 4
Dependent Claim
139 words
A curved beam apparatus for supporting and manually positioning a scintillation detector to a desirable position relative to a patient which comprises: a) a generally C-shaped support member including means for pivotally supporting the scintillation detector at one end portion thereof; b) a carrier member engaging said support member for retaining said support member and for permitting relatively low friction orbital movement of said support member along a predetermined arcuate path; c) means disposed at one end portion of said support member chordally opposed to said scintillation detector for counterbalancing said scintillation detector thus permitting said support member to retain a relatively fixed position to which it is moved with respect to said carrier member; and d) a base member for rotatably supporting said carrier member and for permitting said carrier member and hence said support member axial rotation.
Claim 5
Dependent Claim
139 words
A curved beam apparatus for supporting and manually positioning a scintillation detector to a desirable position relative to a patient which comprises: a) a generally C-shaped support member including means for pivotally supporting the scintillation detector at one end portion thereof; b) a carrier member engaging said support member for retaining said support member and for permitting relatively low friction orbital movement of said support member along a predetermined arcuate path; c) means disposed at one end portion of said support member chordally opposed to said scintillation detector for counterbalancing said scintillation detector thus permitting said support member to retain a relatively fixed position to which it is moved with respect to said carrier member; and d) a base member for rotatably supporting said carrier member and for permitting said carrier member and hence said support member axial rotation.
Claim 6
Dependent Claim
55 words
A curved beam apparatus according to claim 3 wherein said C-shaped support member is circular, the arcuate path of said support member is circumferential such that the combination of the orbital movement of said support member and the axial rotation of said carrier member by said base member permits spherical positioning of the scintillation detector.
Claim 7
Dependent Claim
32 words
A curved beam apparatus according to claim 3 or 4 wherein said support member further includes a rail along portions of either side thereof for engaging inner portions of said carrier member.
Claim 8
Dependent Claim
27 words
A curved beam apparatus according to claim 5 wherein said carrier member includes a plurality of cam followers adapted for engaging the rails of said support member.
Claim 9
Dependent Claim
40 words
A curved beam apparatus according to any of claims 3 to 6 wherein said carrier member has an opening therethrough for the passage therethrough of a conductor for electrical connection between said scintillation detector and a remote source of power.
Claim 10
Dependent Claim
31 words
A curved beam apparatus according to claim 7 wherein said yoke is open centered to permit said conductor to be connected to the scintillation detector directly through said pivot support means.
Claim 11
Dependent Claim
39 words
A curved beam apparatus according to any of claims 3 to 8 wherein said means for counterbalancing said scintillation detector is a second scintillation detector and said support member includes second means for pivotally supporting said second scintillation detector.
Claim 12
Dependent Claim
21 words
A curved beam apparatus according to any of claims 3 to 9 wherein said base member includes means for lateral motion.
