Scanning device for scintigraphy according to three orthogonal planes

Claim 1

In a device for scintographic scanning according to three orthogonal planes employing two detecting heads arranged for adjustment along, above and transversely of a longitudinal and horizontal beam position the improvement comprising; a beam horizontally disposed in said position, two vertical column structures including chain means for moving the same along said beam; two recording devices; frame support means mounted fixedly on said beam including longitudinally extending carriage guide means and transverse guide means; a horizontally disposed recording surface mounted on said frame parallel to said guide means; chain drive means for moving said carriage along said horizontally extending and transverse guide means respectively; two column carriages mounted for vertical movement along said columns, respectively, having means for moving the same vertically along the columns; each last said carriage including rod means for supporting a detector head for horizontal transverse scanning motion in respect to the support carriage, a first said rod means in one column including a bracket on an outer end thereof for supporting a detecting head in rotatable movement about an inclined axis, the bracket being roTable about the first rod means; a detecting head rotatably mounted on said first rod means at an outer end of said bracket for varying displacement beneath first said rod means and toward the other column as the bracket rotates; a second said rod means in the other said column including a rotatable knuckle at an other end thereof comprising means for supporting a second detecting head beneath said second rod means; a second said detecting means mounted on said knuckle for rotation about the axis of said second rod means; said first and second rod means being adjustable vertically and independently of each other by chain means extending vertically in said columns and horizontally along said beam by further chain drive means operative to move said columns therealong, said detecting heads being rotatively adjustable to detect in like directions vertically and horizontally, said bracket inclinable relative to said first rod means to align said detecting heads horizontally or vertically; means operating said chain means for moving the columns and said chain drive means being selectively operable for effecting desired three plane scanning motions; and means coupling each recording head drive means to effect motion thereof corresponding to scanning motion of said detecting head.
