Computer tomography is a non-invasive layer-by-layer internal organs and structures examination method, which is used in the modern medical care industry. During CT procedures, X-ray radiation is used. It allows obtaining images showing the examined object’s condition. Due to CT utilization, doctors can both examine human organs tissues and study their density, and based on the results obtained, they can come to a conclusion about the disease nature and origin, localize the pathology, and make a correct diagnosis. The procedure is mainly used to conduct a skull, abdominal organs, retroperitoneal space, cardiovascular system, pelvis, and thorax diagnostics.
Depending on the examination area, the following CT imaging types are distinguished:
During a CT scan, the scanner can examine both a single organ and several neighboring organs at a time. In this case, the device provides information about their structure and density and scans lymph nodes and vessels located in the examination area. This approach provides the doctor with the opportunity to see a complex picture and significantly increases the diagnosis accuracy.
The following kinds of equipment are offered on the market:
Single-slice equipment is the simplest on the market. With its help, you can get an image which allows you to obtain superficial information about the disease nature. Multislice CT machines allow obtaining a dual-slice image or multislice one. The higher the number of slices is, the faster the procedure is conducted. In this case, the images quality allows studying even the smallest structures and following the pathology development dynamics. High resolution and a minimal amount of artifacts – that is the multislice scanners advantage. Multislice CT scanners with two X-ray tubes are used mainly in cardiology. These are expensive devices which accurately detect tumors of different densities. They allow you to “see” plaques, study the heart contracts strength, estimate damage to the arteries, and scan the smallest blood vessels.
The most important technical characteristics of such machines are:
A CT scanner looks like a big, square doughnut. The patient aperture (opening) is 60 cm to 70 cm (24" to 28") in diameter. Inside the covers of the CT scanner is a rotating frame which has an x-ray tube mounted on one side and the banana shaped detector mounted on the opposite side. The more slices made by the CT scanner, the more detailed the three-dimensional image. An X-ray tube is a vacuum tube that converts electrical input power into X-rays. Average x-ray tube shelf life is 130,000 scans, or 1 calendar year. Under federal regulation code Title 21, x-ray controls on CT scanners must provide a visual indication when the CT scanner is in use and an audible signal when terminating exposure.
The cost given here of used systems is usually 50-80% lower than the new price. And the prices for OEM refurbished systems are typically 30-40% lower than the new price. As a general indication, see the table below. In the columns are the number of slices, and in the rows are the types of imaging that each type is capable of. The costs of a used 16-32 Slice CT Scanners in this range is typically 35-60.000 USD. The used scanners with 64 slices typically cost 90-130.000 USD. CT Scanners with 256 and More Slices .The costs of these systems range from 250.000 USD and upwards for a used system.
