Objectives of CT
This course is designed to provide specific knowledge and skills on related to Computed tomography and various protocol of CT .
Third Generation of CT Scan.
What Is Third Generation of CT Scan? The third generation CT scanner is also rotate / rotate system with wide fan beam and the angle of fan beam was 50° . Both the x-ray tube and detectors rotate around the patient. The original rotate - rotate scanner used 288...
Second Generation Of CT Scan.
What Is Second Generation Of CT Scan ? The second generation CT scan also rotate / translate system. The 30 detector are used in second generation. This increased the utilization of the x-ray beam by 30 times, compared with the single detector used per slice in...
First Generation Of CT scan.
What is First Generation Of CT scan ? The original EMI unit was the first generation of CT scan. The first generation of ct scan is rotate/ translate pencil beam and Only one detector per tomography section. Only two x-ray detectors were used, and they...
Generation Of CT Scan ( Computed tomography).
What Are The Generation Of CT scan ( Computed tomography) ? In generation Of CT Scan, The CT scan have been developed to acquire the x-ray transmission data for image reconstruction. The CT scan have gone through a number of design change since the technology....
CT Number or Hounsfield Units.
What Is CT Number or Hounsfield Units ? The digital value describe to each pixel is called the CT number or Hounsfield Unit ( HU). The CT number calculate from the scanner data from the linear attenuation coefficient (µ) of each pixel. After reconstruction, the...
Principle of CT( Computed tomography) scan.
Principle of CT( Computed tomography) scan. The principle of CT is The internal structure of an object can be reconstructed from multiple projection of the object. A X-ray tube emitting a fan beam from a small focus is coupled to a...
History Of CT ( Computed Tomography)
History Of CT Scan ( Computed Tomography). What is a CT scan ? The Computed tomography scanner was invented by sir Godfrey N Hounsfield in 1972 and initially named as Computerized axial tomography (CAT). The first head CT scanner was introduced, CT has matured...
