About
Biplab Sarkar is a leading researcher in the field of stereotactic radiotherapy, with a primary focus on the precision and accuracy of patient positioning. His work addresses the critical challenge of reducing complex six-dimensional (6D) positional errors—encompassing lateral, longitudinal, vertical, pitch, roll, and yaw movements—into manageable three-dimensional (3D) linear shifts. Sarkar’s major contributions include developing and verifying a mathematical formulation for this reduction, a methodology that has been cited 19 times and is foundational for frameless stereotactic radiotherapy. He further advanced the field by calculating setup margins based on 6D corrected residual errors from kV cone beam computed tomography (CBCT) and intrafraction imaging, a study with 14 citations that enhances treatment accuracy in both coplanar and noncoplanar geometries. Notably, Sarkar has also critically analyzed the concept of 4π radiotherapy, arguing that it violates solid geometric boundary conditions in three-dimensional Euclidean space, a provocative work that has garnered 7 citations. His ongoing research into rotation-corrected setup margins continues to shape clinical practices, making him a key figure in the quest for submillimeter precision in cancer treatment.
