Three sensors

Oncology

In Boston, medical researchers affiliated with CIMIT, Mass General, and Brigham and Womens Hospital are now completing a Phase II National Cancer Institute grant with Ascension sensors for laparoscopic navigation. The team is developing a new imaging and computer-based navigation system for inserting therapeutic probes in the central duct of the pancreas, a vital organ located deep in the body. Because the pancreas is not easily accessible, years of training are now necessary to perform this procedure; the new system will make this easier and safer while providing better treatments for pancreatic and other soft organ diseases.

The long-term objective is to enhance the efficacy and reduce the morbidity of invasive procedures in the abdomen with improved image-based information. NCI funding will advance three-dimensional, real-time visualization of laparoscopic tools integrated with pre-acquired images.

Image registered endoscopic ultrasound
Image registered endoscopic ultrasound in a human patient. Top Left: B-Scan Ultrasound Image. Top Right: Image Reformatted CT Data in US-Defined Plane. Bottom: 3D CT-based Model of Patient Abdominal Organs for Navigation and Biopsy Probe Positioning. The ultrasound image plane in green is shown bisecting the left kidney in orange.
Surface models of the pancreas
Surface models of the pancreas segmented from the CT examinations of four patients after alignment in the same coordinate frame. Each color represents a different patient. The shape and size of the pancreas are similar among these patients.
