3D Images of Computed Tomography Help in Accurate Diagnosis
Computed tomography (CT) is a type of medical imaging method that is used to produce clear pictures of body organs. 3D computed tomography scanning can be performed through the digital geometry processing. CT scanning came into light in 1971. A normal x-ray uses a special light called “ionizing radiation” to produce a picture. Similarly, CT scan takes the picture from one angle.
3D images of the body parts of an object give a clear picture for the exact treatment. Large series of 2D X-ray images are taken around a single axis of rotation. A CT machine takes images to put together a 3D model. The classic application of industrial X-ray computed tomography (CT) takes three-dimensional (3D) computed tomography measurement of metal and plastic castings. With the help of this technology, physicians are able to take images of the internal organs, bones, soft tissue and blood vessels to know the details.
The contemporary CT scanners offer isotopes or near isotropic, high resolution of images. It has been possible because of software program to build a volume by "stacking" the individual slices one on top of the other. This imaging technology uses faster computer systems and newer software strategies that can process individual cross sections. The computer system integrates the data of the moving individual slices to produce 3D computed tomography information.
Unlike CT scans, X-ray examinations depend on ionizing radiations. The diagnosis of lung cancer can be found with a biopsy and using the latest technology of 3D computed tomography scan. However, there are chances of surviving this dreadful disease, if it is not diagnosed in time by taking some preventive measures and cancer treatment.
