Focused ultrasound gives hope in Parkinson's disease
A new Spanish-led study suggests that focused ultrasound may benefit patients with asymmetric Parkinson's disease, in which symptoms are much more severe on one side of the body. Using precise, focused ultrasound energy had a very strong effect on parkinsonian symptoms, the investigators found.

How to train the medical physicists of the future
At the recent European Society for Radiotherapy and Oncology meeting in Milan, a debate examined the skills that medical physicists will require in 10 years' time and asked how training for medical physicists specializing in radiation oncology should develop over the next decade. Five expert speakers presented their thoughts -- and then let the audience decide.

Conebeam CT mitigates cardiac motion during imaging
Robotic C-arm conebeam CT helps guide interventional cardiac surgical procedures and can be valuable in radiotherapy, but the intrinsic motion of the beating heart causes blurring and image artifacts. A new technique can help overcome this limitation.

Patient phantom helps bring cranial SRS into mainstream
Stereotactic radiosurgery (SRS) is a high-precision radiotherapy technique that's finding particular value in the treatment of multiple brain metastases. Cranial SRS, however, is also one of the most complex and challenging radiation treatments, and one that many radiotherapy departments don't have the confidence -- or access to sufficient quality assurance tools -- to implement.
