GPU-Based Ultra Fast and Ultra Low Dose Cone Beam Computed Tomography Reconstruction
University of California System: University of California, San Diego Technology Transfer Office
posted on 03/14/2010
Cone-beam computed tomography (CBCT) plays an important role in image guided radiation therapy (IGRT). However, the large radiation dose from serial CBCT scans in most IGRT procedures raises a clinical concern, especially for pediatric patients who are essentially excluded from receiving IGRT for this reason.
Advantages
- Up to a 98 percent reduction in imaging dosage is achievable using the fast CBCT reconstruction algorithm.
- Processing is 100-fold faster than current iterative reconstruction approaches.
Detailed Description
UC San Diego researchers have developed a fast GPU-based algorithm to reconstruct CBCT from under-sampled and noisy projection data so as to reduce the total imaging dose. The high computation efficiency in this algorithm allows for real-time iterative CBCT reconstruction in clinical environments.
