About
Sandhya Rottoo is a rising medical physicist whose work is tackling one of radiotherapy’s most pressing global challenges: equitable access to treatment. Her research centers on the development of a novel, low-cost orthovoltage radiotherapy system designed specifically for low-resource settings, including low- and middle-income countries and rural regions. Her most-cited paper, “Initial characterization of a novel dual-robot orthovoltage radiotherapy system” (2025, 4 citations), introduces a device that uses non-coplanar techniques to reduce the global disparity in radiotherapy access. Building on this foundation, her second most-cited work, “Development of a motorized iris collimator for kilovoltage x-ray radiotherapy” (2025, 2 citations), details the design of a lightweight, 12-leaflet motorized iris collimator weighing just 4.8 kg, which enables precise beam shaping for this innovative system. Through these contributions, Rottoo is not only advancing the engineering of affordable radiotherapy but also laying the groundwork for scalable, cost-effective cancer care in underserved communities. Her work represents a critical step toward democratizing access to life-saving treatment worldwide.
