iContour
Interactive Contouring Platform for Radiation Oncology
Bringing Contouring to Mobile and VR.
The Contouring Problem
Contouring is a critical procedure for delivering treatment in radiation oncology. Poor contouring frequently occurs in the low accruing treatment centers and can cause incompliant treatment plans, causing a decrease in the patient's long-term survival rate.
While existing contouring tools are usually manifested as standalone software or web-based applications, and only support traditional mouse/keyboard for information input, it is challenging for newcomers who usually choose to purchase a high-end mouse to achieve better control precision while drawing contours on slices.
Our Solution
iContour (Interactive Contouring Platform for Radiation Oncology) aims to address this problem by designing innovative software support for contouring procedures on mobile and VR devices, with richer input/output modalities. This can create tremendous impacts on the future computer-supported structure segmentation tools for resident training and real-world oncological disease diagnosis.
