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...

Area of Science:

  • Medical Physics
  • Radiotherapy Technology
  • Image Processing

Background:

  • Adaptive radiotherapy (ART) aims to improve treatment efficiency.
  • Daily cone beam computed tomography (CBCT) is increasingly used in radiotherapy.
  • Accurate image data is crucial for effective adaptive planning.

Purpose of the Study:

  • To evaluate the feasibility of using a CBCT correction algorithm for daily treatment planning.
  • To assess the impact of CBCT correction on dose calculation accuracy in ART.
  • To determine if the algorithm can reduce the need for re-simulation.

Main Methods:

  • A CBCT correction algorithm was applied to phantom and patient data.
  • CBCT images were processed to reduce artifacts and match planning CT intensity.
  • Treatment plans generated on CT were recalculated on corrected CBCTs.
  • Dose differences were analyzed using 3%/2 mm gamma analysis.

Main Results:

  • The CBCT correction algorithm produced high dose agreement on a lung phantom.
  • All 14 patient plans (head and neck, sarcoma) achieved >95% gamma passing rate after corrections.
  • The algorithm effectively generated corrected CBCTs for treatment planning.

Conclusions:

  • The CBCT correction algorithm shows potential for faster offline adaptive planning.
  • This approach may reduce the need for repeat CT scans (re-simulation).
  • Dose calculation accuracy is maintained with the use of corrected CBCT data.
