Control system for an MRI compatible intracavitary ultrasound array for thermal treatment of prostate disease

MRI-derived temperature measurements may be useful for a feedback control system that non-invasively regulates the temperature distribution by adjusting the power to the elements of the array. MRI has been shown to provide accurate, high resolution, non-invasive thermometry.

Heritability of hippocampal size in elderly twin men: Equivalent influence from genes and environment

Recent studies have established that environmental factors can modify hippocampal structure and enhance function in adult rodents, but the extent to which genes and the environment exert differential contributions to hippocampal structural integrity in humans is unknown.

A multielement RF coil for MRI guidance of interventional devices The University Hospitals of Cleveland/Case Western Reserve University Interventional MR Program is supported in part through research collaborations with Siemens Medical Systems and Radionics, Inc.

While a single one-element micro coil incorporated into an interventional device has proven to be effective in some applications, it can only supply tip position information. However, multiple positions on the device are necessary to also determine its orientation.
