Ct scan machine parts and functions pdf. These slices are called. Parts are rotated in the scanner and imaged hundreds of times. CT scans are also referred to as computerized axial tomography.
Image reconstruction techniques can then be applied to derive the matrix of linear attenuation coefficients which is the basis of the CT image. CT tube corresponding to large kilovolts and milliampere settings. Modern CT technology can be understood as a natural progression of improvements and innovations in response to both engineering problems and clinical requirements.
As the scan are normally extended for many slices and many revolutions the final dose can be as high as 50 to 100 millisievert see defi - nition of Sievert in nuclear medicine chapter of this book. For a typical CT scan an operator positions a patient on the CT table and prescribes a scanogram or âscout view. More to the complexity different CT scan manufacturers often modify the design of various components.
Heat is considered the undesirable product of this conversion process. Detailed discussions of multislice CT CT image quality evaluation and radiation doses in CT will be. 1963 - theoretical basis of CT A.
