Modern pixelated electron counting detectors provided a giant leap in the use of cryogenic electron microscopy (cryo-EM) by structural biologists to study the structures of macromolecules and complexes thereof. Ideally, a detector for cryo-EM would give a list of position, time and energy of each individual electron that arrives at the detector surface with infinite accuracy. The ultimate...

Next generation detection systems operating in multispectral mode have the potential to revolutionize diagnostic capabilities in medical imaging in terms of efficiency, image quality and lower patient dose.

We present our approach that utilizes direct conversion radiation detectors operating in Photon Counting (PC) mode.
Our strategy is to use several different detector technologies...

25. Signal to Noise Ratio optimization for extended sources with a new kind of MURA masks

Coded aperture imaging is a well known technique for localization of radioactive hot-spots. Its advantages are high detection efficiency and under certain configurations wide Field of View (FOV). We have used a simple assembly technique which results in coded masks with high transparency, low weight and which can be restructured easily. We present the study of the reduction of the intrinsic...

ABSTRACT
Introduction: Breast cancer is the most common cancer in women. Early detection of breast cancer is a crucial aspect for an effective therapy. Mammography (MMG) is the most used technique for screening, able to identify small-size tumours at the early stage; nevertheless MMG showed reduced performance in case of dense breast. Magnetic Resonance Imaging, Ultrasound and Molecular...

167. Enhanced volume resolution by inline spot-convolution in iterative volume reconstruction : Canceled

In the classic understanding the achievable volume resolution in computed tomography depends on a number of system parameters, i.e. detector pitch, focal spot size and geometric magnification.
However, at second glance, this fundamental assumption turns out to be rather inaccurate. Given, for example, a detector with a box-like point function (PSF), with an edge response much narrower than...

13. Minimizing CPU Utilization Requirements to Monitor an ATLAS Data Transfer System

Mr Georgios Leventis (CERN)

general

Oral

ATLAS[1] experiment at LHC will use a PC-based read-out component called FELIX[2] to connect its Front-End Electronics to the Data Acquisition System. FELIX translates proprietary Front-End protocols to Ethernet and vice versa. Currently, FELIX makes use of parallel multi-threading to achieve the data rate requirements. Being a non-redundant component of the critical infrastructure...

89. Mass measurement and study of decay properties of super heavy elements by using the pixel detectors

Mr Lubos Krupa (Institute of Experimental and Applied Physics, Czech Technical University in Prague, Husova 240/5, Prague 1, Czech Republic)

general

Oral

The discovery of the Super Heavy Elements (SHE) with atomic number Z=113-118 as well as new neutron excess isotopes of the elements with Z=104-112 was one of the outstanding scientific results of the last decades. These high priority experiments were carried out on the cyclotron U400 of the FLNR (JINR, Dubna, Russia). The synthesis of the new super heavy elements stimulated works on the...
