Bidhu Kalyan Mohanti

About

Bidhu Kalyan Mohanti is a medical physicist whose research focuses on the precision and geometric accuracy of stereotactic radiotherapy. His key contributions lie in developing mathematical frameworks to correct complex six-dimensional (6D) patient positioning errors—encompassing lateral, longitudinal, vertical, pitch, roll, and yaw—into simpler, clinically actionable three-dimensional (3D) linear shifts. This work is critical for frameless stereotactic treatments, where even sub-millimeter inaccuracies can compromise outcomes. His most cited paper (2018, 19 citations) introduces a validated methodology for this 6D-to-3D reduction, while a subsequent study (2019, 14 citations) calculates intrafraction setup margins using kV cone-beam CT and projection imaging for both coplanar and noncoplanar geometries. Mohanti has also engaged in theoretical debates within the field, notably challenging the feasibility of "4π radiotherapy" on conventional linear accelerators, arguing that the concept violates solid geometric boundary conditions in 3D Euclidean space. Through his rigorous spatial assessments and mathematical validations, Mohanti has advanced the safety and efficacy of stereotactic radiotherapy, providing physicists and clinicians with practical tools to minimize rotational errors and improve treatment delivery accuracy.
