Neutron crystallography helps develop new drugs

Biophysicists are using neutron crystallography to take a lot of the chance out of drug discovery.

Medical physics: past, present and future

The PMB 60th Anniversary Symposium examined the evolution of medical physics since 1956, where the field is now, and where it may be in 60 years' time.

MR-guided radiotherapy: how great is the need?

With existing image-guided radiotherapy approaches providing highly accurate dose delivery, how great is the need for large-scale in-room MR guidance?

Physics or biology: where does radiotherapy's future lie?

A debate at the ESTRO 35 conference examined whether physics- or biology-based advances will best enable radiotherapies to maximize tumour control.

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.

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.
