E-book examines global radiation oncology

A new e-book, Emerging Models for Global Health in Radiation Oncology, examines the emerging field of global radiation oncology.

Introducing gating to small-animal irradiation

Adding respiratory gating to precision small-animal radiotherapy systems enables preclinical irradiation of mobile tumours.

Proton RBE: is 1.1 just a myth?

Is the fixed value of 1.1 commonly used for proton RBE inappropriate, or the only viable clinical option?

MRI-guided radiotherapy: two years on

Two years on from the first MRI-guided radiation treatment, we take a look at how this guidance capability has impacted clinical practice.

The Grand Challenge: tackling the toughest cancer questions

The Grand Challenge awards aim to tackle the most important unanswered questions in cancer research.

Review of the year: 2015's most popular stories

We look back at some of the most popular articles published on medicalphysicsweb over the last year.

Beam-on PET tracks proton dose in real time

PET imaging of short-lived positron emitters could provide real-time feedback on dose delivered during proton therapy.

Beyond the diffraction limit: super-resolution microscopy

The 2015 super-resolution microscopy roadmap examines the underlying concepts and potential applications of this non-diffraction-limited optical imaging technique.

Where next for MRI-guided radiotherapy?

In his inaugural lecture, UMC Utrecht's Bas Raaymakers described the rationale behind the MRI-linac and what the future may hold for MRI-guided radiotherapies.

Four takes on intra-fraction motion monitoring

Medical isotope supplies: a game plan for the future

A Canadian task force has identified a promising alternative method for making large quantities of Mo-99, using natural uranium and photons from a high-power accelerator.

Medical physicists: preparing for change

As the boundaries between medical disciplines become increasingly blurred and those between diagnosis, therapy and management follow suit, how can medical physicists adapt to these changing needs?

Radiotherapy: challenges old and new

Long-standing tasks such as dealing with organ motion, as well as the new challenges arising from state-of-the-art beam-delivery systems, were the talk of this year's ESTRO meeting.

Ionizing radiation: the double-edged sword

With cancer survivors now younger and living longer, it's pertinent to ask whether recent advances in conformal radiotherapy modalities come at a latent cost.

High-performance computing: shaping medicine's future

Tools such as grid networks and supercomputers will play a vital supporting role in biomedical research and clinical development.

Cellular imaging draws disciplines together

The traditionally diverse disciplines of biology and physics are finding common ground in the effort to image cellular functions.

Particle therapy: protons and beyond

Most particle-therapy treatments are performed using proton beams; but could carbon ions ever become a practical alternative?

Optical imaging comes to the fore

Optics-based techniques such as fluorescence and Raman imaging are poised to play a bigger role in cancer diagnostics.

Setting the standards for IMRT

Wide variations in dose prescription and delivery between institutions highlight the pressing need for universal IMRT planning and reporting guidelines.

Technology assessment: why magical thinking won't do

Newer isn't always better, which is why a rigorous examination of emerging clinical technologies is in everyone's interest.
