Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area of Science:

Otolaryngology
Medical Imaging
Surgical Navigation

Background:

Computer-aided systems enhance confidence in endoscopic sinus surgery by enabling navigation through complex anatomy.
Conventional systems lack intra-operative updated computed tomography (CT) imaging.
The xCAT is a novel intra-operative mobile volume CT scanner designed to address this limitation.

Observation:

A case study involved a patient undergoing surgery for malignant melanoma with a computer-aided system updated with intra-operative CT images.
The GE InstaTrak 3500 Plus system successfully integrated real-time CT data.
The integrated images correlated accurately with the observed endoscopic anatomy.

Findings:

The xCAT scanner provides intra-operative mobile volume CT imaging capabilities.
Successful integration of updated CT images into existing surgical navigation systems is feasible.
The system demonstrated consistency between intra-operative imaging and endoscopic visualization.

Implications:

The xCAT represents a significant technological advancement for endoscopic sinus surgery.
This technology can improve surgical precision and confidence in complex rhinological and skull base procedures.
Enhanced intra-operative imaging facilitates better surgical decision-making and patient outcomes.
