Research Summary:

Dr. Chugh’s research is focused on developing methods for accurate Image-Guided Radiation Therapy (IGRT) using Magnetic Resonance Imaging (MRI). MRI provides invaluable structural and functional information that can help tailor treatments to patient-specific tumour biology. With the advent of integrated MRI-RT technologies such as MRI simulators and MR-linacs, it is now possible to incorporate a wide variety of MRI parameters for IGRT. The scope of application is vast, including tumour detection and staging, treatment simulation, guiding positioning, monitoring treatment response, providing data for adaptive radiation therapy (ART) as well as surveillance and prognosis.
