About
Saneg Krishnankutty is a medical physicist whose research focuses on improving the precision and safety of stereotactic radiotherapy (SRT), particularly through the analysis of patient positioning errors. His key contributions lie in the development of more accurate set-up margins that account for both translational and rotational positional errors—a critical factor in frameless SRT, where even minor misalignments can compromise treatment outcomes. In his most cited work (2019, 14 citations), Krishnankutty introduced a novel spatial assessment method using six-dimensional (6D) corrections from kV cone beam CT and intrafraction imaging, calculating set-up margins for both coplanar and noncoplanar geometries. This work provides a practical framework for reducing intrafraction errors in stereotactic treatments. His subsequent study (2022, 7 citations) further refined these margins by converting 6D setup errors into 3D translational equivalents, offering a streamlined approach for clinical implementation. Together, these studies have established Krishnankutty as a thoughtful contributor to the field of radiation oncology physics, helping to bridge the gap between complex geometric error analysis and everyday clinical practice.
