X-ray microscopy setups based on the principle of geometric magnifcation are attractive for laboratory setups because of the simplicity of the concept as well as the possibility to use a wide range of photon spectra. However, in such setups the focal spot size of the source limits the spatial resolution that is achievable. Therefore an X-ray source providing a nanometer sized focal spot is...

Hadron therapy uses ion beams for irradiation of tumorous tissue. Ions have highly localized dose deposition in contrast to photon radiation. A main advantage of ions is that they deposit the most of energy at the end of their range according to the Bragg curve. Unfortunately the ion beams often generate a substantial amount of secondary particles with longer range. Thus certain fraction of...

The fast and precise determination of crystal structures using the Laue diffraction method requires a simultaneously position- and energy-resolved detection of photons. By means of a back side illuminated pnCCD with frame-store operation [1] the spatial distribution of Laue spots as well as their energies can be measured at the same time. The sensitive volume consists of a fully sideward...

The Super Advanced X-ray Emission Spectrometer (SAXES) [1] at the ADRESS beamline [2] of the Swiss Light Source (SLS) is a high-resolution X-ray spectrometer used as an end station for Resonant Inelastic X-ray Scattering at 400 to 1600 eV [1].
It disperses photons across a CCD, allowing the energy of scattered photons to be determined by the spatial position. The limiting factor of the...

We analyze the imaging performances of the microstrip silicon detector operated in counting mode under mammography imaging condition. Although the detector has an asymmetric pixel size of about 100 (width) by 500 (height) microns, the 100-micron slit aperture of the beam collimator shapes a practical symmetric pixel pitch of 100 microns. Since the detector is composed of four separate linear...

An integrated portable USB based readout interface for the ATLAS semiconductor trackers (SCT) has been built. The ATLAS SCT modules are large area silicon strip detectors designed for tracking of high-energy charged particles resulting in collisions on Large Hadron Collider (LHC) in CERN. These modules can be also used on small accelerators for medical or industry applications where a compact...

In ion beam therapy the finite range of the ion beams in tissue and the presence of the Bragg-peak are exploited. Unpredictable changes in the patients condition can alter the range of the ion beam in the body. Therefore it is desired to verify the actual ion range during the treatment, preferably in a non-invasive way. Positron emission tomography has been used successfully to monitor the...

X-ray transmission radiograms of Aluminum alloy contain features induced by variations of the material chemical composition. Generally, material variations are strongly connected with grains of the metal, where the material composition of one individual grain is more or less homogenous. However, material composition varies from one grain to other. Grains of the studied material have typically...

Non-invasive analysis techniques we have recently developed with the pixel detector Timepix have shown great potential for the inspection of the objects of cultural heritage. We have newly developed the instrumentation and methodology for in-situ X-ray transmission radiography and X-ray fluorescence imaging. With the methods successfully tested we are evaluating the mobile system for remote...

We are developing a positron emission tomography (PET) insert based on avalanche photodiodes (APDs) arrays and monolithic LYSO:Ce scintillators with the aim of being used for human brain studies inside a clinical 3T MRI equipment. In a previous work [1], we demonstrated the performance of our detectors by implementing an experimental setup consisting of two monolithic blocks working in...

A range verification method plays an important role in the quality assurance of the proton therapy offering the high conformity and reduction in radiation dose. To localize the distal falloff of the dose distribution, secondary particles (C-11, O-15, N-13) produced by the proton interaction within the patient body can be used as a measure of the beam range. We proposed a multi-modality imaging...

Compared with conventional gamma-ray emission imaging device based on mechanical collimation, the Compton imaging technique based on so-called ‘electronic collimation’ could provide better performance in terms of imaging resolution and sensitivity when the gamma-ray source to be imaged has relatively high energy, i.e., more than a few hundreds keV. We have developed a prototype...

Neutron detection is a very difficult work because it directly does not generate secondary charge particles. So far, (n, n) elastic scattering or (n, x) nuclear reaction leading to emission of charged particle is the most common detection methods. In recent year there is an increasing interest in neutron imaging method. In the low-energy range there are several materials that can be classified...

The function of a dosimeter is to display the absorbed dose of radiation, where a particular type of radiation is usually targeted. Recently, there have also emerged applications where all kinds of radiation are absorbed and sorted by pattern recognition, such as the Medipix2 application in [1]. This form of smart dosimetry enables measurements where not only the total dosage is displayed, but...

For medical imaging devices and techniques the emphasis is generally put on obtaining high resolution and low dose images of samples or patients. Hybrid single photon counting devices together with new sensor materials and advanced techniques of image reconstruction makes this requirement more feasible. In particular cases like direct observation of dental implants also the size of the imaging...
