Contrast enhanced dual-energy CBCT gadolinium imaging for liver SBRT

Stereotactic body radiation therapy (SBRT) relies critically on image guidance for accurate tumor visualization and patient positioning to deliver high radiation doses to tumor while sparing normal organs at risk. Tumor visualization with cone beam computed tomography (CBCT) is inherently poor in liver SBRT patients. Gadolinium (Gd) based contrast agents can remain in liver for 1-2 hours providing tumor contrast due to its high atomic number. Previous studies demonstrated that CBCT imaging for contrast enhancement is feasible but only at high concentrations of Gd. However, high Gd concentrations is prohibitive due to potential toxicity thus its maximum safe concentration level is regulated by Health Canada. However, tumor contrast enhancement with low Gd concentration may be achieved by dual-energy technique. This technique uses two separate CBCT images at high and low energies and applies material decomposition algorithm to obtain images of a specific tissue type. The objective of this research project is to implement CBCT dual-energy decomposition technique to create Gd-only images. This is an exciting MSc level project that involves establishing baseline image quality and determining optimal imaging parameters using clinical CT and CBCT equipment in the contest of liver SBRT.
