Assessment of 3D Transperineal Ultrasound Imaging w/ Matrix Array Transducers in Prostate Radiotherapy

Assessment of 3D Transperineal Ultrasound Imaging With Matrix Array Transducers as a Potential Imaging Modality for Adaptive Prostate and Post-Prostatectomy Radiotherapy

SPECIFIC STUDY AIMS

1. To evaluate congruence between pelvic anatomical structures segmented on MRI and/or CT scans co-registered with transperineal US scans acquired with an optically and/or electromagnetically tracked matrix array ultrasound transducer.
2. To estimate the achievable accuracy of anatomy tracking based on 3D US matrix-array transducer imaging and grey-level based image registration algorithms.
