Transcranial ultrasound (TCUS) can be used to diagnose and monitor a range of neurological conditions, such as Parkinson’s disease. However, reliable quantitative examination and multi-modal image analysis that involves TCUS require TCUS-MRI registration to guide the interpretation and measurement of the TCUS. We demonstrate that accurate rigid registration can be achieved through aligning gradient orientations of the 3D TCUS and an associated pseudo-TCUS constructed from the T1w MRI.
