Background/introduction Magnetic resonance imaging (MRI)-guided transurethral ultrasound therapy is a minimally-invasive image-guided treatment for localized prostate cancer offering precise targeting of tissue within the gland. The accuracy of MR thermometry is critical for precise on-line feedback control as well as for monitoring potential thermal injury of surrounding tissues, especially th...

Background/introduction Non-invasive ablation and hyperthermia treatments of abdominal organs using High Intensity Focused Ultrasound (HIFU) still impose severe challenges. Especially for liver and kidney treatments, the target motion and accessibility over the entire respiratory cycle make the application of HIFU difficult. To allow for a safe, effective, and efficient treatment, detailed plan...

Abstract Background A novel electromechanical robotic-exoskeleton was designed in-house for the rehabilitation of wrist joint and Metacarpophalangeal (MCP) joint. Objective The objective to compare effectiveness (clinical-scales neurophysiological-measures) robotic-therapy training sessions with dose-matched conventional therapy in patients stroke. Methods pilot prospective parallel randomized ...

Objective: In this study, in order to establish a more effective therapeutic model for the patients with chronic rotator cuff tendinosis, the authors attempted to compare the therapeutic effects of general physical therapy, eccentric contraction exercise, extracorporeal shock wave therapy (ESWT) and their combination for patients with noncalcific subscapular tendinosis. Methods: 120 patients wi...

Tumors in thoracic and upper abdomen regions such as lungs, liver, pancreas, esophagus, and breast move due to respiration. Respiration-induced motion introduces uncertainties in radiotherapy treatments of these sites and is regarded as a significant bottleneck in achieving highly conformal dose distributions. Recent developments in radiation therapy have resulted in (i) motion-encompassing, (i...

The primary goal of post-surgical rehabilitation following cartilage repair (microfracture, grafting, autologus chondrocyte transplantation) is to control pain, reduce inflammation, protect the repaired tissue during the healing process, restore function, improve range-of-motion, and accelerate soft tissue healing. During the initial healing phase following surgery, six to eight weeks4,11,16,25...

Background Three-dimensional, whole-heart, navigator-gated, contrast-enhanced MRI techniques are used to acquire cMRVs which can be used for planning lead placement in cardiac resynchronization therapy (CRT). In order to reduce cardiac motion artifacts, it is desirable to set the trigger delay time to acquire image data only during periods of low vessel motion, typically assumed to be during di...

Background The amount and location of left ventricular (LV) mechanical dyssynchrony affects an individual’s ability to respond positively to cardiac resynchronization therapy (CRT) [Bax et al JACC 2005]. By using high temporal resolution short-axis cines, it is possible to derive radial motion curves throughout the LV. These radial motion curves can be used to create maps showing dyssynchronous...
