Small-animal single-photon emission computed tomography (SPECT) system plays an important role in the field of drug development and investigation of potential drugs in the preclinical phase. The small-animal High-Resolution SPECT (HiReSPECT) scanner has been recently designed and developed based on compact and high-resolution detectors. The detectors are based on a high-resolution parallel hole...

Large field of view gamma cameras are widely used to perform lymphoscintigraphy in the sentinel lymph nodes (SLN) procedure in case of breast cancer. However, they are not specified for this application and their sizes do not enable their use in the operative room to control the excision of the all SLN. We present the results obtained with a prototype of a new mini gamma camera developed especi...

Given any non-compact real simple Lie group $\mathrm{G}\_o$ of inner type and even dimension, we prove the existence an invariant complex structure $\mathrm{J}$ a Hermitian balanced metric on compact quotient $\mathrm{M}= \Gamma\backslash\mathrm{G}\_o$, with $\Gamma$ cocompact lattice. We also that $(\mathrm{M},\mathrm{J})$ does not carry pluriclosed metric, in contrast to case dimensional grou...

The purpose of quality control (QC) is to detect changes in the performance of a gamma camera system that may adversely affect the interpretation of clinical studies. Clearly, there are a large number of factors that contribute to the final image quality, including uniformity, resolution (both intrinsic and energy), collimation and the hard copy device. In addition, for certain types of studies...

This paper presents a method to reduce the cost of the conventional gel documentation system by employing a much cheaper digital camera instead of the existing expensive one. To adapt the cheaper camera, a computer remote control function which is necessary to the gel document system was added. The gel imaging performance of the camera was qualitatively and quantitatively analyzed in comparison...

We describe the principles of a device comprised of a static camera and rotating plane mirror that enables the passive recovery of 3D range information. The range recovery can be regarded as either structure from known motion or as virtual multi-camera stereo. Two advantages of the arrangement are that the camera-mirror system is compact and that range information can be recovered over a wide, ...

We calculate the complete set of two-loop leading-colour QCD helicity amplitudes for $\gamma \gamma j$-production at hadron colliders. Our results are presented in a compact, fully-analytical form.

Some of the very high energy (VHE) gamma-ray sources detected with the modern generation of Cherenkov telescopes have been identified with previously known X-ray binary systems. These detections demonstrate the richness of non-thermal phenomena in compact galactic objects containing relativistic outflows or winds produced near black holes and neutron stars. Recently, the well-known microquasar ...
