The movie shows how the EndoScout system is used to guide a cryotherapy of a renal tumor:

The EndoScout tracking system acquires the location and orientation of a sensor during an MRI scan. The sensor is a 3 dimensional magnetic field sensor made by 3 orthogonal pick up coils. According to the clinical application, the sensor comes in different sizes and shapes, to fit the specific application. Two of the most popular ones are the basic cube sensor for hand held guided tool and the micro sensor with about 1.5 mm diameter for small tools, catheters and more.

The tool is the interface between the physician hand and the patient. Its purpose is to help the physician navigate a needle to a specific location inside the patient. There are different kinds of tools for different applications. Needless to say that all tools are MRI compatible.

Motion during scan induces image quality degradation (blurred images, motion "ghost" artifacts) to a degree that may require repetition of the scan. The sensitivity to motion increases with newer imaging like functional and diffusional MRI and with higher resolution scanners. As 20-30% of all scans are affected by motion, the direct annual financial burden of motion artifacts, due to the need to repeat scans, is estimated at $1 Billion in the USA alone.

The EndoScout system enables tracking of the location and orientation of miniature sensors during an MRI scan (for more information about the sensors click here). The tracking is based on the native gradient fields of the MRI scanner, thus there is no need to register the tracking system to the scanner before each use. The system can be easily installed and used on any scanner, with no need to modify the scanner or its mode of operation and with no electromagnetic interference.
