CT scan Radiation therapy and contrast Injector.

The  C.T Scan gantry assembly is the largest of these systems. It is made up of all the equipment related to the patient including the patient support the positioning couch the mechanical supports and the scanner housing. It also contains the heart of the CAT scanner the x-ray tube as well as detectors that generate and detect x rays. Computed Tomography is a well accepted imaging modality for evaluation of the entire body. The internal structure of the object can be reconstructed from multiple projections of the object.  VARIOUS PARAMETERS OF CT: SliceMatrix PixelVoxel CT number Windowing Window widthWindow levelPitch The relationship between patient and tube motion is called Pitch and result is spiral CT scanner. HV power supply is explained with electronics circuits. Data Acquisition refers to a method by which the patient is systematically scanned by the X ray tube and detectors to collect enough information for image reconstruction. MDCT Detectors Patient table Slip ring Power Transmission are explained with pictures. Radiation therapy is also dealt extensively. Contrast Injector is also mentioned and shown with pictures. Maintenance Repair and Trouble shooting are given. Temperature controller for detector cooling of X-ray Tube are given clearly.
