More accurate biopsy by augmented reality

“We would like to layer the information from the MRI and other vein scans (from sensor devices using laser speckle) and make them visible with augmented reality”, says Dr. Eng. Beril Sirmacek (Computer Science). This allows doctors to see the inner body segments, tumours, veins and the status of diabetic ulcers with the use of augmented reality. This visual support enables doctors to oversee the situation better and make better decisions. In a biopsy situation, this visual support can help with guiding the robot arms to reach the tumour for biopsy at the first attempt, instead of taking the off-chance and reach for the correct location by working with a patient for a whole day and making unsuccessful biopsy holes on the patient's body.

The augmented visualisation of big data and the guidance with the smartphone application highly relies on the technology of Simultaneous Localization And Mapping (SLAM). “Even though I didn't have a medical background, our common focus on SLAM and AR provides a great platform.”

“When we started this project, our goal was to develop a SLAM box at the UT research group RAM (Robotics and Mechatronics). We can use our localisation and 3D reconstruction software on different sensors and not only with the use of smartphones. Our vision will lead to many health applications, and other robotics applications will become more intelligent. With this technology, the algorithms quickly understand the 3D models of the surrounding objects regardless of the imaging sensors which are used.”

Prof. Dr. Ir. Stefano Stramigioli (Chairman of the Group, Robotics and Mechatronics):“SLAM is a core technology in robotics, but its universal usage will only be possible if we have methods to interface many sensors in a robotic system easily. At RAM, we intend to create a modular SLAM box which will automatically reconfigure itself if additional sensors are attached in a Plug&Play fashion. Then it would be possible to connect this “SLAM Box” to a complete robotic system, giving it powerful perception capabilities.”
