A new generation of gamma cameras is on the horizon, thanks to a collaboration between the BioImaging Unit of the Space Research Centre at the University of Leicester, the Institute for Cancer Research at the Royal Marsden Hospital (Surrey) and medical physicists at the Leicester Royal Infirmary.
Dr John Lees, who leads the BioImaging Unit, is developing the new camera using funding from the University’s seedcorn fund, Lachesis. It will be a small, affordable hand-held device, producing higher resolution images than those currently in use. The camera uses novel technology based on Charged Coupled Devices (CCDs), which have been used in X-ray astronomy for many years and are also used in dental X-ray imagers.
Gamma imagers are used to view tumours and lymph nodes in patients, but those available at present are large, expensive items of equipment which do not produce high resolution images. The smaller imagers which Dr Lees is developing can be used alongside the bigger gamma cameras, in order to focus more closely on a tumour or other medical condition.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
