Computed tomography (CT) known as CT scanning combines the use of X-rays with a computer system to obtain images in the form of thin cross-sections of the human body. Advances in technology allow radiation dose adjustment (optimization) using GE's ASIR technology as well as the use of the LOW DOSE scanning technique on the sophisticated "GE Optima CT660 -128 slice" device, which is also adapted for scanning heart vessels (CT coronary angiography), even with an accelerated heart rate and a frequency of up to 120 beats per minute, which was not feasible for previous generations of CT devices. You can scan the head, neck, chest (thorax), abdomen, small pelvis, as well as all vascular structures (angiography) in a short period of time due to the high speed of imaging.
