Abstract
A patient table assembly (10) is fixedly mounted on pedestals (14, 16) with a table top (12) passing through a central aperture (116) of a rotatable inner gantry (110). The inner gantry (110) is rotatably mounted in an outer gantry (80) which selectively moves parallel to the table top along tracks (82). The foot end pedestal (14) has an arm (30) and a flange and contour block arrangement (36) which receives a foot end (40) of the table top fixedly therebetween. A slide (58) clamps the head end of the table top to an arm (50) connected with the second pedestal. A front wheel carriage (90) includes a pair of wheels (98) which are rotatably mounted to a pivot member (92) for limited rotation about the outer gantry (80). Detector heads (112, 114) are mounted to slide members (132, 136,156,158) which slide on guide members (134, 138). A motor (140, 152) and acme screw ( 142, 154) drive one slide along the guide members. Flexible cables (174, 190) prevent a free side slide from canting the detector head under the force of gravity. Electrical or fluid cables (202, 204) from the detector heads pass around rollers (210, 212). A wire rope (218) has its opposite ends connected with the rolle…
