Computed Tomography (256 Slice CT) is a highly advanced imaging technology that provides detailed, high-resolution cross-sectional images of the body. By capturing multiple slices simultaneously, this system allows specialists to visualize internal structures with exceptional clarity, speed, and accuracy. It plays a crucial role in modern medical diagnostics within the field of medical technologies.
The Evolution of Computed Tomography
Traditional CT scanners captured a limited number of slices per rotation, often requiring longer scanning times and exposing patients to higher radiation doses. Early systems provided essential imaging but lacked the speed and resolution needed for complex cases.
The introduction of multi-slice CT scanners, and particularly the 256-slice CT, has revolutionized medical imaging. By acquiring a large number of slices in a single rotation, these systems provide detailed 3D reconstructions of organs, vessels, and tissues while minimizing scan time and enhancing patient comfort.
How 256-Slice CT Works
A 256-slice CT scanner consists of an X-ray source and a series of detectors arranged in a circular gantry. As the gantry rotates around the patient, the X-ray beams pass through the body and are detected by the sensors. Advanced reconstruction algorithms process the data to produce high-resolution cross-sectional images.
The large number of detectors allows the acquisition of 256 slices simultaneously, enabling rapid imaging of large anatomical regions. Combined with 3D reconstruction software, specialists can visualize complex structures such as the heart, brain, and vascular system in remarkable detail.
