Visualization of Fiber Tract Uncertainty during Neurosurgery

In modern neurosurgical practice, a surgeon can see a patient’s fiber tracts (nerve tracts) on a monitor in the operating room. This design study investigates the benefit of adding the uncertainty of the tracts and aims to improve the surgeon’s orientation while reducing visual clutter.<br/><br/>Based on an interview with a neurosurgeon and our...

Environment Observation Module for the Deci Zebro: Obstacle and Motion Detection using a Laser Rangefinder and Optical Flow

A Camera Submodule for the Environment Observation Module for a Zebro robot was designed. It is able to collect and process data about obstacles on a Raspberry Pi and send this to the main processor of the Environment Observation module using UART. <br/>The two main functions that were implemented are a laser rangefinder based on triangulation...
