Computed Tomography01:10

Computed Tomography

7.6K
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...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Cone-beam computed tomography (CT) is increasingly used for medical imaging.
  • Dedicated scanners can optimize imaging for specific anatomical regions.
  • Extremity imaging requires high resolution and appropriate radiation dose management.

Purpose of the Study:

  • To assess the initial image quality and radiation dose of a prototype cone-beam CT scanner designed for extremity imaging.
  • To evaluate the diagnostic potential and limitations of this dedicated extremity CT system.

Main Methods:

  • Technical assessment of a prototype extremity cone-beam CT scanner.
  • Radiation dose measurement across varying kilovolt peak (kVp) and milliampere-seconds (mAs) settings.
  • Contrast resolution evaluation using signal difference-to-noise ratio (SDNR).
  • Spatial resolution assessment with a line-pair phantom.
  • Qualitative review of cadaver images by a musculoskeletal radiologist.

Main Results:

  • A nominal scan protocol (80 kVp, 108 mAs) resulted in a dose of 9 mGy.
  • Optimal contrast resolution was achieved at 80 kVp, enabling visualization of soft tissues and bone.
  • Spatial resolution exceeded 15 line pairs per centimeter in the axial plane.
  • Minor artifacts (scatter, beam hardening, cone-beam) were noted but did not significantly impede visualization.
  • Cadaver images showed excellent bone and good soft-tissue detail.

Conclusions:

  • The dedicated extremity cone-beam CT scanner demonstrates sufficient image quality and favorable dose characteristics.
  • The system is capable of imaging both upper and lower extremities, including weight-bearing examinations.
  • Further clinical evaluation is warranted to establish its utility in routine practice.
