3D Microwave Tomography Using the Soft Prior Regularization Technique: Evaluation in Anatomically-Realistic MRI-Derived Numerical Breast Phantoms
MRI breast images with microwave tomography is combined through a soft prior technique, incorporating spatial information from MRI into the regularization process of the image reconstruction algorithm. Numerical experiments were completed on MR-derived 3D breast geometries with different parenchymal densities, as well as a simulated tumor. When the soft prior technique was applied, relative root mean square error values decreased in all cases across all breast densities. The incorporation of structural priors significantly increased the recovered contrast between tumor and fibroglandular tissue. This study confirmed that the soft prior regularization algorithm is robust in our 3D microwave image reconstruction.
Patient Registration Using Intraoperative Stereovision in Image-guided Open Spinal Surgery
In this study, we established the feasibility of using intraoperative stereovision as a radiation-free, low-cost imaging modality to register pre-operative CT images of the spine…
