Validation of an image-guided robot system for measurement, biopsy and injection in rodents

Abstract

We developed an image-guided robot system to achieve highly accurate placement of thin needles and probes into in-vivo rodent tumor tissue in a predefined pattern of about 1 mm granularity that is specified on a preoperative image. This development is part of a collaborative project between Johns Hopkins University (JHU) and Memorial Sloan-Kettering Cancer Center (MSKCC). This paper presents a design update and validation results for the robot system that we constructed and delivered to MSKCC.
