The AAPM conference featured the latest research in the physics of medical imaging and radiation therapy, including a major focus on the increasing integration on advanced imaging technologies in the guidance of medical therapeutics.

ARDENT ESR Michele Togno presented the latest results in the characterization of a new ionization chamber technology, which is suitable to build detectors for quality assurance in external beam radiotherapy.

Such a technology would be particularly valuable in association with advanced treatment modalities such as rotational radiotherapy, stereotactic treatments (even with unflattened beam qualities) and proton therapy.

The Position Sensitive Neutron Detectors (PSND) 2014 workshop was strongly focused on the shortage of He-3 used in active neutron detectors for various applications of radiation protection and high energy physics. Several new technologies based on innovative materials were proposed and the new prototypes developed in different laboratories around the planet were presented. This workshop was a good opportunity to discuss the opportunities as well as challenges of efficient fast neutron detection with world-wide experts currently working in this field. The results from experiments carried out at the CNAO Hadron-therapy facility to characterise the spectrometric capabilities of the CR-39 neutron detector, were presented during this workshop by Alvin Sashala Naik (ESR 13).
