Abstract:
1. A patient bed adapted to be received within a gantry of at least one imaging device for a multiple position emission scan, said patient bed comprising: a horizontal rail base secured to a support surface; a magnetic track disposed along a length of said horizontal rail base; a linear motor cooperating with said magnetic track to impart horizontal motion on said linear motor along said length of said horizontal rail base, said linear motor being actuated to move said linear motor along said magnetic track; a pedestal carried by said linear motor, whereby as said linear motor is moved along said magnetic track, said pedestal is moved horizontally along said length of said rail base; a vertical track carried by said pedestal for controlling vertical travel of said patient bed; a linear actuator for imparting vertical motion along said vertical track; a pallet support member carried by said linear actuator, said pallet support member defining a substantially planar member having a proximal and a distal end, said proximal end being secured to said linear actuator and said distal end being cantilevered from said linear actuator; and a pallet for holding a patient during the emission scan, said pallet being disposed above said pallet support member and defining a proximal end and a distal end, said proximal end being secured proximate said pallet support member proximal end, said pallet support member distal end engaging said pallet along a length thereof whereby said pallet is maintained at a constant vertical position irrespective of horizontal position.
