Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Acquire CT data and US and transducer position data (magnetic sensor system) of focal hepatic or renal lesions to serve as sample data sets for fusion algorithm development and subsequent optimization.

Optimize image fusion algorithms for use in goal. Develop registration algorithms that result in maximal lesional overlap with a clinically relevant difference in an epicenter location of ≤ 2 cm for lesional identification and, ultimately ≤ 0.3 cm for interventional procedures.
