Nishikant’s research work lies at the intersection of Medical Imaging, Computer Vision, Parallel Programming, and Computer Graphics. He primarily works on accelerating an ultrasound-based technique called elastography that enables surgeons to perform cancer tumor detection during a surgery.
Combining 3D B-mode and 3D elastography visualized over time gives a 5D ultrasound system. Nishikant has developed the world's first 5D ultrasound system. The 5D ultrasound system work has been published in the International Journal for computer assisted radiology and systems. Nishikant has developed these systems as a real-time system capable of acquiring data from an ultrasound machine to elastography processing.
