Toshiba 640 layer ct machine is the first one of the equipment introduced in Guangzhou with a capital of nearly more than 30 million yuan, and is the most advanced whole-body tomography equipment.
Product Features
CT is different from traditional radiography, the X-ray detection system used in CT is more sensitive than the photographic film, and computer processing of the detector information obtained. the characteristics of CT is that it can distinguish between the X-ray absorption value of a very small difference. In comparison to conventional radiography, CT can distinguish a range of densities of more than 2,000 levels, whereas conventional X-rays can distinguish only about 20 levels of density.
This density resolution not only distinguishes fat from other soft tissues, but also distinguishes the density classes of soft tissues. This revolutionary technology has dramatically changed the way many diseases are diagnosed.
When performing a CT examination, the most common tomographic plane used today is the horizontal cross-section, where the thickness and location of the tomographic plane can be determined by the examiner. Commonly, the thickness of the layers ranges from 1 to 10 millimeters, and the patient is moved through the examining frame to obtain multiple sequential images that can be combined to form the body structure.
Thinner slices give more accurate information, but more slices must be scanned for a given volume.
The information obtained in each exposure is reconstructed by a computer to form an image that can be displayed on a fluorescent screen or captured on film for permanent storage. In addition, the basic information can be stored on disk or tape.
