G03B 4116

US Classification:

250445T

Abstract:

An axial tomographic system having scanner means normally in an "off" condition where all power sources associated therewith are electrically isolated from the units driven thereby, means for activating the scanner means to establish an "on" condition, control means including means to measure one or more system parameters when the scanner means is in an "on" condition and to determine if the measured parameters are within predetermined limits therefor, and means for maintaining the "on" condition only if the control means is properly operational and all measured system parameters are within the predetermined limits therefor.

Abstract:

Means for supporting an object, or a portion thereof, during radiographic analysis comprising a hollow reservoir adapted to receive and hold a constant volume of fluid material within the interior thereof, said reservoir having a pouch-like flexible member forming all or a portion of one wall thereof, said pouch-like flexible member being adapted to receive and support the object undergoing analysis during radiographic exposure thereof, a second flexible member forming all or a portion of a second wall thereof, and means operatively connected to said second flexible member for moving said second flexible member so as to cause a corresponding movement of said pouch-like flexible member. During use, the second flexible member is moved in such a manner as to cause an enlargement of the pouch-like deformation of the pouch-like flexible member. After the object to be examined is inserted in the enlarged deformation, the second flexible member is moved so as to cause the pouch-like flexible member to conform to the exterior surface of the object and thereby provide proper support therefor during the radiographic procedure.
