Abstract
Abstract A scanner for scintigraphy of the entire body, comprising: a frame provided with horizontally and lengthwise located guides; a carriage, movable with respect to the frame, along said guides, and provided with transversely slidable supports for one or two rods supporting the detectors; one or two rods slidable transversely on said supports, on said rods being mounted the detectors; one or more recording devices for the scintigraphic image; comprising a stationary rail parallel to the bed for the patient, and rolling means suitable to cause the sliding movement guided by the rail, of the frame with the carriage, the rods with the detectors and the recording devices, the rail being so located that most of the scanner slides between the rail and the patient bed, this too stationary, during the longitudinal scanning movement on the entire body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A scanner for scintigraphy of a body comprising: a. an elongated rail member adapted to be positioned at a bed to extend longitudinally of the bed parallel to a side thereof; b. a frame member movably supported on said rail member; c. first guide means connected to said frame member and extending parallel to said rail member; d. a carriage movably supported on said first guide means; e. support means connected to said carriage for movement therewith and extending transverse to said rail member; f. a rod member slidably mounted on said support means for movement transverse to said rail member; g. a scintigraphic detector mounted on said rod member for movement therewith, said detector adapted for positioning over the bed; h. a recording means coupled to said scintigraphic detector for recording scintigraphic images as detected by said detector; and i. drive means for moving said frame member along said rail, for moving said carriage member along said first guide means, and for moving said rod member along said support means to move said detector longitudinally and transversely with respect to the bed.
Claim 2
Dependent Claim
183 words
A scanner for scintigraphy of a body comprising: a. an elongated rail member adapted to be positioned at a bed to extend longitudinally of the bed parallel to a side thereof; b. a frame member movably supported on said rail member; c. first guide means connected to said frame member and extending parallel to said rail member; d. a carriage movably supported on said first guide means; e. support means connected to said carriage for movement therewith and extending transverse to said rail member; f. a rod member slidably mounted on said support means for movement transverse to said rail member; g. a scintigraphic detector mounted on said rod member for movement therewith, said detector adapted for positioning over the bed; h. a recording means coupled to said scintigraphic detector for recording scintigraphic images as detected by said detector; and i. drive means for moving said frame member along said rail, for moving said carriage member along said first guide means, and for moving said rod member along said support means to move said detector longitudinally and transversely with respect to the bed.
Claim 3
Dependent Claim
60 words
A scanner as claimed in claim 1 further comprising a second rod member slidably mounted on said support means for movement transverse to said rail member, a second detector mounted on said second rod member for movement therewith; and a second recording head coupled to said second scintigraphic detector for recording scintigraphic images as detected by said second scintigraphic detector.
Claim 4
Dependent Claim
50 words
A scanner as claimed in claim 1 further comprising second guide means connected to said carriage and extending transverse said first guide means; and in which said recording means is slidably mounted on said second guide means, and said drive means moves said recording means on said second guide means.
Claim 5
Dependent Claim
39 words
A scanner as claimed in claim 3 in which said drive means includes a system of chains and gears providing a predetermined reduction ratio between the longitudinal movement of said detector and the longitudinal movement of said recording means.
Claim 6
Dependent Claim
49 words
A scanner as claimed in claim 4 in which said drive means further includes a system of chains and gears providing said predetermined reduction ratio between the transverse movement of said detector and the transverse movement of said recording means, to record the scintigraphic images in a reduced scale.
Claim 7
Dependent Claim
34 words
A scanner as claimed in claim 5 in which said drive means includes means for preventing movement of said frame member along said rail while said carriage member moves along said first guide member.
Claim 8
Dependent Claim
91 words
A scanner as claimed in claim 6 in which said drive means further includes means controlling the ratio of the movement of said rod member relative to the movement of said recording means to permit the movement of said recording means to be reduced with respect to movement of said rod member, thereby allowing recording at the reduced scale, while also permitting the movement of said recording means to be equal to the movement of said rod member, thereby allowing recording at full scale of the scintigraphy of a reduced area.
Claim 9
Dependent Claim
33 words
A scanner as claimed in claim 1 in which said drive means includes a single motor and clutch means coupling said motor to said frame member, said carriage member, and said rod member.
Claim 10
Dependent Claim
34 words
A scanner as claimed in claim 1 in which said drive means includes means for preventing movement of said frame member along said rail while said carriage member moves along said first guide member.
Claim 11
Dependent Claim
93 words
A scanner as claimed in claim 1 in which said drive means includes means controlling the ratio of the movement of said rod member relative to the movement of said recording means to permit the movement of said recording means to be reduced with respect to movement of said rod member, thereby allowing recording of scintigraphic images at a reduced scale, while also permitting the movement of said recording means to be equal to the movement of said rod member, thereby allowing recording at full scale of the scintigraphy of a reduced area.
