About
T Ganesh is a medical physicist whose research focuses on the precision and accuracy of stereotactic radiotherapy, particularly in frameless systems. His major contributions center on developing mathematical frameworks to correct for six-dimensional (6D) patient positioning errors—encompassing translational shifts and rotational inaccuracies like pitch, roll, and yaw—and reducing them to manageable three-dimensional (3D) linear shifts. This work is critical for ensuring sub-millimeter treatment delivery in high-dose, high-precision radiation therapy. His most cited paper (19 citations) introduces a methodology for this 6D-to-3D reduction, while a subsequent study (14 citations) calculates setup margins by correcting rotational errors using kV cone-beam CT and intrafraction imaging. Ganesh has also critically examined emerging concepts like 4π radiotherapy, arguing against its geometric feasibility with conventional linear accelerators. His 2022 work continues to refine setup margin calculations for frameless stereotactic treatments. Through these contributions, Ganesh has advanced the practical implementation of image-guided radiotherapy, helping to bridge the gap between theoretical treatment planning and real-world patient positioning accuracy.
