Imaging Studies III: Computed Tomography

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...

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...

Area of Science:

Medical Imaging Physics
Radiological Technology
Quality Assurance in Medical Imaging

Background:

C-arm Cone Beam Computed Tomography (CBCT) systems are increasingly used for volumetric imaging.
Quality control (QC) is essential for ensuring the reliable performance of these advanced imaging systems.
Existing QC protocols for C-arm fluoroscopy provide a foundation, but C-arm CBCT requires specific considerations for 3D imaging.

Conclusions:

The described methodologies aid medical physicists in determining system performance and identifying the need for calibration.
Consistent data collection on image quality and radiation dose supports the development of performance criteria and standards.
Proactive assessment using established QC procedures ensures optimal C-arm CBCT system operation and clinical reliability.
