SPIRAL CT SCAN
Computed Tomography Imaging
Computed Tomography (CT or “CAT” Scan) scanning is a rapid, painless diagnostic examination that combines x-rays and computers. A CT scan allows the radiologist to see the location, nature, and extent of many different diseases or abnormalities inside your body. CT scanning can be used to obtain information about almost any body organ (such as the liver, pancreas, intestines, kidneys, adrenal glands, lungs, and heart), blood vessels, the abdominal cavity, bones, and the spinal cord.
Advantage Workstation 4.2
The powerful new suite of image display & analysis tools are incorporated in Advantage Workstation (version 4.2) and are designed to streamline even your most data-intensive procedures while providing the most advanced image processing and display capabilities for advanced analysis, Post Processing and 3D Imaging.
Spiral CT Scan
Our center has Spiral CT scanners equipped with new software techniques and workstations i.e. Advantage Workstation 4.2 which generate data and detail quickly and accurately.
Body Imaging
CT imaging is particularly useful because it can show several types of tissue with great clarity, including organs like the liver, spleen, pancreas and kidneys, lung, bone, soft tissue and blood vessels—with great clarity. Using specialized equipment and expertise to create and interpret CT scans of the lower gastrointestinal (GI) tract, the colon and the rectum, an experienced radiologist can accurately diagnose many causes of abdominal pain such as an abscess in the abdomen, an inflamed colon or colon cancer, diverticulitis, cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders and appendicitis. Often, no additional diagnostic workup is necessary and treatment planning can begin immediately.

Three-Dimensional (3D) Image Reconstruction
A volume rendering of this volume clearly shows the high density bones.
Bone reconstructed in 3D
After using a segmentation tool to remove the bone, the previously concealed vessels can now be demonstrated.

Virtual Bronchoscopy (VB)
Multidetector CT generated virtual bronchoscopy (VB) represents one of the most recent developments in three-dimensional (3D) visualization techniques which allows a 3D evaluation of the airways down to the sixth- to seventh-generation. In comparison with real bronchoscopy, VB has some advantages: it is a non-invasive procedure that can visualize areas inaccessible to the flexible bronchoscope.
Several approaches to virtual endoscopy are being explored in the biomedical imaging field. The figure below shows a polygonal based method. The airways of the Visible Human male have been segmented and polygonal models have been created. The coloration of the airways has been obtained from the cryo section data and mapped onto the polygonal model. Realtime manipulation allows the physician to investigate the anatomy in an intuitive manner including the execution of a virtual endoscopic exam.
