Radiology Computed Tomography In the field of diagnosis, computed tomography (CT) has played a major role in scanning, giving detailed images of the structures inside a body. This technology has led to a detailed study of the function and problems pertaining to the human body. In CT, an x-ray source and x-ray detectors, enclosed in a doughnut-shaped assembly, move in a circular path. In general, multidetectors are used as they allow quicker scanning and high-resolution of images. A patient lies on the motorized table that moves to and fro through the assembly. X-ray images of the desired body part are taken from multiple angles and are reconstructed into 2D or 3D images (tomograms). This technique of tomographic imaging can also be applied to radionuclide scanning such as single-photon emission CT (SPECT) and positron-emission tomography (PET), in which the sensors encircle the patient in order to uptake radiation emitted by the body. Furthermore, computer techniques convert the data obtained from the sensor into tomographic images. In this study, we elaborate on multislice spiral computed tomography (MSCT), which is a promising technique for clinical applications such as lesion detection and noninvasive coronary angiography.
