Grant Information

Ongoing Research Support
Project number: 287103.594000.2012
Contact Principal Investigator: Joseph Paydarfar MD
Source of support: Norris Cotton Cancer Center Pilot Award
Title of project/subproject: Development and validation of a CT compatible retractor system for image guided transoral robotic cancer resection
Dates of approved/proposed project: 8/1/2019 – 6/30/2021

Project Number: 1R21CA246158-01
Sponsor/Funding Source: NIH
Contact Principal Investigator: Ryan Halter PhD
Award Period: 07/01/20 – 06/30/22
Project Title: Image guidance for trans-oral robotic surgery
Major Goals: The overarching aims of this program are to reduce complications and improve outcomes for minimally invasive robot-assisted throat cancer surgery by enhancing the surgeon’s ability to assess tumor extent and localize vascular and other critical anatomic structures. We aim to examine the feasibility of image guidance technology by developing CT compatible instrumentation and taking advantage of existing intraoperative CT and surgical navigation resources to develop a framework for image-guided trans-oral robotic surgery (igTORS).
