A Robot To Destroy Breast Cancer Cells
Roland Piquepaille writes "Researchers at the University of Maryland are developing a robot able to detect and destroy breast cancer cells in a single session. After a tumor is located on an MRI, the robot will perform a biopsy of the breast while the patient is inside the scanner. 'If the biopsy displays cancerous cells, the robot will then insert a probe into the breast until it reaches the tumor. The probe will then burn the cancer cells until they are destroyed.' This looks great, but the researchers have only built a prototype. After they refine this robot, they'll need to go through clinical trials and obtain FDA approval. So this is not a robot that will appear on the medical market before several years."
There's a better description of the technology from the lab involved here:

'The goal of this project is to develop a novel teleoperated robotic system with haptic (sense of touch) feedback capability that will provide accurate feedback to the physician performing Breast biopsy (Bx) and/or Radio-frequency ablation (RFA) under continuous Magnetic Resonance Imaging (MRI). Some of the primary challenges of this project include: development of a compact robot manipulator, actuation and sensing that is MRI compatible, efficient use of MRI image sequences to guide the Bx needle and/or RFA probe accurately using adaptive control schemes that incorporate soft-tissue properties as the needle/probe traverses the tissue, and an intuitive user-interface which will provide real-time MRI images and Bx needle/RFA probe tracking with respect to the tumor (target) location.'
You don't have to wait for any cells to grow to make use of the biopsy (it can be assessed directly), but obviously a pathologist will have to examine the sample under a microscope before a treatment decision is made.
