Innovation: patent applications review

Our survey of the latest international patent applications in medical imaging reviews filings from Hologic, Philips, PhotoDetection Systems and more.

Image Gently achieves global reach

By its second anniversary, the Image Gently campaign has evolved into a global movement to raise awareness of radiation dose.

A closer look at bubble-enhanced HIFU

Simulating bubble dynamics at the microscopic level provides insight into the bio-effects of microbubble-enhanced ultrasound therapy.

'Spot scan' proton plans gain safety margins

Shaping the beam to cover an expanded target volume ensures comprehensive tumour coverage during spot scanning proton therapy.

Lung CAD boosts radiologist accuracy

CAD technology can improve the performance of even experienced thoracic radiologists in assessing lung nodules on CT.

Dose check for VMAT plans

VMAT treatments can be checked in vivo using portal dosimetry to provide a fully 3D representation of delivered dose.

In brief: research round-up

Recent developments in functional MRI, PET, proton therapy, cardiac CT and more.

Super-thin probe finds fluorescing plaques

Catheter-based NIR fluorescence imaging can help detect vulnerable plaque in coronary-sized arteries.

Advances in X-ray detection

The SPIE Medical Imaging conference saw researchers present the latest developments in X-ray detector technologies.

SPECT and MRI get it together

Researchers demonstrate the feasibility of simultaneous MR/SPECT imaging.

MR-guidance: the next step for IGRT?

As imaging becomes an indispensable part of the radiotherapy process, will MR-guided treatment prove the way forward?

High-resolution detector eyes IMRT QA

A silicon strip detector with sub-millimetre spatial and sub-second temporal resolution may prove ideal for measuring steep dose gradients.

Quantitative PET: fundamental challenges

Improving quantitation in PET/CT imaging could aid in the development of new cancer therapies.

Ultrasound on the brain

Delegates at this week's SPIE Medical Imaging conference heard how focused ultrasound can ablate brain lesions, and do a lot more besides.

Digital mammography delivers less radiation

ACRIN data reveal that full-field digital mammography delivers much less radiation than analogue mammography.

PET with clustered pinholes

A collimator based on clusters of pinholes could enable high-resolution SPECT imaging of positron emitters.
