We developed a non-voxelbased broad-beam (NVBB) framework for IMRT capable of direct treatment parameter optimization (DTPO). In this framework, both objective function and derivative are evaluated based on the continuous viewpoint, abandoning 'voxel' and 'beamlet' representations. Thus pre-calculation and storage of beamlets are no longer needed.

2010年6月2日 · Purpose: IMRT treatment plan optimization requires a fast yet accurate algorithm to calculate intermediate dose in each iteration. Conventional finite size pencil beam (FSPB) approaches have limitations such as: limited resolution, significant pre-calculation time, huge memory demand, and limited accuracy in the presence of heterogeneity.

The nonvoxel-based broad-beam (NVBB) framework [3] was developed to handle IMRT optimization and proved to be effective. This chapter gives a summary review of the NVBB framework. Dive into the research topics of 'Non-voxel-based broad beam framework: A summary'. Together they form a unique fingerprint. Lu, W., & Chen, M. (2015).
