  • Making Ultrasound Smart for Localization and Diagnosis of Thyroid Nodules Rochester, Minn.

    The purpose of this study is to develop an ultrasound based detection and classification system that achieves high negative predictive value and specificity for malignancy, which could reduce unnecessary biopsies.

  • Three-Dimensional Ultrasound Imaging for Measurement of Total Kidney Volume and Renal Blood Flow Rochester, Minn.

    The primary purpose of this study is to measure total kidney volume (TKV) from multi-sweep freehand 3D US using a Philips EPIQ scanner with a 2D curved array C5-1 probe and an electromagnetic (EM) orientation tracker attached to the probe, and from panoramic 3D using X6-1 matrix probe. To segment the kidney from US volume in a fully automated manner, we will use deep learning approaches. We will also use MR-based measurements of TKV as the gold standard by which we will evaluate the accuracy of the US based measurements.
