Computed Tomography01:10

Computed Tomography

4.5K
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 Physics
  • Computational Dosimetry
  • Radiation Protection

Background:

  • New upright and tilting CT scanners require accurate radiation protection assessments.
  • Traditional methods for radiation shielding rely on dose distribution estimations.

Purpose of the Study:

  • To develop and apply a Monte Carlo computational method for calculating isodose curves.
  • To assess radiation protection requirements for a novel upright and tilting CT scanner.

Main Methods:

  • Utilized the TOPAS code platform with imported CAD files to model the scanner.
  • Simulated a water phantom to represent patient scatter.
  • Calculated maximum intensity dose maps across various tilt angles.

Main Results:

  • Isodose lines were more rounded and closer to isotropic compared to single-tilt angle calculations.
  • Results align with isotropic scatter assumptions used in CTDI and DLP-based radiation protection.
  • Dose distribution showed less dose above the isocenter due to increased shielding material.

Conclusions:

  • The upright tilting CT scanner's radiation shielding needs are comparable to standard CT scanners.
  • The assumption of an isotropic scatter source is valid for radiation protection planning.
  • No unique shielding modifications are necessary for this new scanner design.
