It permits the gantry frame to rotate continuously, eliminating the need to straighten twisted system cables.
Microphone
Laser light
Slip ring
Generator
Usually located on the side of the gantry opening or in place that will allow the technologist to control the alignment of lights, gantry tilt and table movement.
Aperture
Control panel
Microphone
Laser light
It produces the x-ray photons that create the CT image. Their design is a modification of a standard rotating anode tube made of Tungsten. CT tube is designed to handle enormous amount of stress.
Xray source
Pre patient collimator
Post patient collimator
Collimation
It is located below the patient and above the detector array and shapes the beam after it has passed through the patient. It ensures that the beam has the proper width as it enters the detector thus preventing the scatter radiation from reaching the detector.
Post patient collimator
Pre patient collimator
It is located near the x-ray source and limits the amount of x-ray emerging to thin ribbons. It resembles small shutters with an opening that adjusts, dependent on the operator’s selection of slice thickness thus affecting the patient dose by how the dose is distributed across slice thickness.
Pre detector collimator
Pre patient collimator
It restricts the x-ray beam to a specific area, there by reducing scatter radiation thus, reducing patient dose and increasing image quality. Collimators also control the slice thickness by narrowing or widening the x-ray beam.
Collimation
Filtration
Cooling system
Entire collection of detector in a CT system that is arranged in ring or arc.
Ct patient table
Detector
Detector array
Collimator
Generators produce high voltage and transmit it to the x-ray tube that determines the range of exposure techniques available.
Detector
Filtration
Generator
Pre detector
Usually located on the side of the gantry opening or in place that will allow the technologist to control the alignment of lights, gantry tilt and table movement.
Control panel
Aperture
Microphone
Laser light
Allows communication between the technologist and the patient through out the procedure.
Laser light

Ct scanner are complex, with many different components involved in the process of creating an image.
True
False
Measure the intensity of transmitted x-ray radiation along a beam projected from the x-ray source to that particular detector element. The collected information by the detectors is from the x-ray beam that passes through the patient and is attenuated to some degree thus, producing an image.
Detector array
Collimator
Detector
Collimation
This process of moving the table by a specified measure
Incrementation
Patient table
Computer console
Composed of hardware and software components. Its computer system is fed and gathered with information as the CT x-ray tube has been activated.
Ct console
Ct patient table
Ct gantry
Process of data collection from the detectors.
Display data
Data acquisition
Scanning the patient
