Registration of Tomographic Images to X-ray Projections for Use in Image Guided Interventions
… to be used during an intervention which is guided using 2D fluoroscopy images. <br/><br/>An algorithm has been designed to obtain the pose of a CT volume with respect to a single fluoroscopy image. The registration algorithm is based on the production of digitally reconstructed radiographs …

On-chip magnetic sensor and readout design for 3D position tracking in image-guided interventions
… EMT is particularly beneficial in various image-guided interventions, enhancing accuracy and safety. Despite its advantages, EMT has not been widely adopted in common procedures such as laparoscopic surgery and non-robotic endoscopy due to the prohibitive cost of the sensors, which range …

Development of a Three-Dimensional Image-Guided Needle Positioning System for Small Animal Interventions
… accuracy. To improve the outcomes of these interventions a small animal needle positioning system guided by micro-computed tomography (micro-CT) imaging was developed. A phantom was developed to calibrate the geometric accuracy of micro-CT scanners to a traceable standard of measurement. Use …

Creating an open source electromagnetic tracking platform
… (EMT) platform for use in minimally invasive and image-guided interventions; Anser EMT. The goal of this work is to advance the state of the art of electromagnetic tracking systems by creating an open-source electromagnetic tracking platform for pre-clinical research and development. The specific …

Real-time membrane puncture detection using force sensors for micro-injections in phantoms
… animals and other resources. An ultrasound-guided robot developed at Robarts Research Institute was revised to implement closed-loop force feedback to compensate for tissue deformation during micro-interventions. Force sensors can detect puncture events as the needle penetrates tissue …
