One quarter of women who undergo breast lumpectomy to treat early-stage breast cancer in the United States undergo a repeat surgery due to concerns that residual tumor was left behind. This has led to a significant increase in women choosing mastectomy operations in the United States. We have developed a mixed-reality system that projects a 3D “hologram” of images from a breast MRI onto a patient...
This paper presents an algorithm for a 3D segmentation of the aorta artery in magnetic resonance images (MRI). The purpose is to project the 3D segmented aorta in the patient's abdomen with an augmented reality (AR) system to help the surgeon in laparoscopic interventions. In order to obtain accurate results in the segmentation process a marker-controlled watershed algorithm is used. Since this method...
Virtual and augmented reality environments have been adopted in medicine as a means to enhance the clinician's view of the anatomy and facilitate the performance of minimally invasive procedures. Their value is truly appreciated during interventions where the surgeon cannot directly visualize the targets to be treated, such as during cardiac procedures performed on the beating heart. These environments...
The following work describes in the field of neuro endoscopy the possibilities offered by active endoscopes equipped with augmented reality features and able to perform quantitative measurements. In the NEAR project, a practical implementation targeted towards endoscopic third ventriculostomy (ETV) and realized with standard optical systems and endoscopes is used as an example to discuss the limits...
