| Abstract: | This project is part of the MURAB project. The MURAB project is aimed at improving cancer diagnostic operations. To performbreast biopsy,Magnetic Resonance Imaging (MRI) scans and ultrasound (US) data are used to locate the position of the lesions which need to be targeted. A biopsy gun/needle will be inserted which needs to be guided to these targeted areas. The needle will take a sample of the region. Currently a radiologist inserts the needle assisted by an ultrasound probe. The output of the ultrasound probe is shown on a monitor next to the person who is being scanned. The HoloLens developed byMicrosoft provides a way to create virtual objects in the real world, these objects can be tied to positions in the real world. The HoloLens can also be used to create a 3D model of the region of interest in the patient which can then be explored for diagnosis purposes. This can also be used to showthe inside of the patient to guide the radiologist toward the lesion. In this report is described how one can develop an application for the HoloLens to visualize the MRI scans over a patient in real time and show the location of tools such as a needle and its proximity to the target. To do this, the location of the breast, lesions and needle is gathered and translated to the same coordinate system. The gathering of the positional data is done by external tracking devices and sent to the HoloLens. The HoloLens translates the information to give useful information to the physician. Such that it improves the ability of the radiologist to take a sample. It was found that the accuracy of the current system is not enough to perform biopsies, but with several possible improvements it could likely be made sufficiently accurate. |
