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.

Computational grids in radiotherapy: optimal IMRT planning

Wed, 14 Jan 2009 11:45:09 GMT

For the ultimate in radiotherapy treatment planning, try selecting an optimal plan from a large set of quasi-optimal potentials. Such a scheme could be enabled by exploiting the power of a computational grid, argues Dimitri Dimitroyannis.

Disruptive thinking on proton therapy

Mon, 22 Dec 2008 09:50:50 GMT

TomoTherapy's Rock Mackie believes that disruptive innovation will transform the economics and logistics of proton therapy. Joe McEntee reports on plans to make protons a mainstream treatment option.

IMRT: next move, biological optimization?

Thu, 11 Dec 2008 11:34:51 GMT

The unique beam-delivery conditions of IMRT offer an opportunity to optimize the biological response of tumour cells to therapeutic irradiation, explains Natalka Suchowerska of the Royal Prince Alfred Hospital in Sydney, Australia.
