In vivo dosimetry: implementation issues

Wed, 28 Oct 2009 11:23:54 GMT

In vivo radiotherapy dosimetry has a great deal to offer, so why is it not more widely deployed? Writing in the British Journal of Radiology, Craig Edwards takes a closer look.

Bringing medical physics to the developing world

Fri, 25 Sep 2009 09:44:54 GMT

Setting up medical physics facilities in developing countries requires not only access to appropriate systems, but also effective training of staff to operate and maintain this equipment. Henry Lawrence discusses his experiences.

Threats to ultra-high-field MRI

Thu, 27 Aug 2009 07:47:10 GMT

A European directive designed to prevent workers from being exposed to high magnetic fields could potentially have a severe impact on research into MRI, warns Denis Le Bihan.

Radiation therapy risks: prioritizing patient safety

Tue, 04 Aug 2009 13:47:43 GMT

In a comprehensive review of radiotherapy safety incidents, Jesmin Shafiq and Michael Barton reveal that although errors leading to serious incidents are rare, it's vital that treatment centres implement and continually monitor risk-reducing measures.

Volumetric-modulated arc therapy: its role in radiation therapy

Thu, 25 Jun 2009 07:45:51 GMT

VMAT is currently a hot topic in radiotherapy. But it's still lacking a universal theory relating the resulting dose distribution and clinical outcome to input parameters, explains Steve Webb.

The potential of PET: a closer look

Mon, 08 Jun 2009 12:01:15 GMT

PET/CT shows great potential for target delineation in radiation therapy planning. In a recent paper in the journal Academic Radiology, Habib Zaidi reviews progress in molecular-imaging-guided radiotherapy.

Off-the-shelf commercial software is helping scientists to enhance the clinical efficacy of photodynamic therapy for targeted tumour destruction, reports Joe McEntee.

Diagnostic imaging: advancing radiation protection

Wed, 15 Apr 2009 07:50:46 GMT

Web-enabled QA software tools could help the medical physics community develop a quantitative risk-benefit framework for diagnostic radiology, explains Michael Moores.

IMRT planning: biological models take a central role

Thu, 12 Mar 2009 11:51:12 GMT

Using tumour control probability models for IMRT planning could enable the ultimate balance between control and toxicity, explains NKI's Marnix Witte.

Clinical implementation: how can IMRT become routine?

Mon, 16 Feb 2009 11:29:04 GMT

IMRT offers the potential for superior target coverage and reduced normal-tissue exposure, so why is it not yet the standard radiotherapy modality at all clinical centres? Marco Schwarz discusses.
