The Advanced Photon Source (APS), located within Argonne National Laboratory, is the brightest source of hard-x-rays in the Western Hemisphere. This has enabled full-field x-ray imaging with the highest spatial and temporal resolutions, using either absorption or phase-contrast. This talk will provide an overview of the present status of full field x-ray imaging. Examples from biology and...

CMOS monolithic active pixel sensors have been established in recent years as the technology of choice for new generation digital imaging systems for Transmission Electron Microscopy. With respect to conventional, optically-coupled CCD-based cameras, the advantages of this technology lie on one side in the possibility for direct detection with single electron sensitivity, which greatly...

To assist our ongoing investigations of the limits of the tradeoff between spatial resolution and noise in PET imaging, several PET instruments based on silicon-pad detectors have been developed. The latest is a segment of a dual-ring device to demonstrate that excellent reconstructed image resolution can be achieved with a scanner that uses high-resolution detectors placed close to the...

This work investigates the possibilities of improving the measurements of arrival time difference of the two 511 keV photons arising from annihilation of a positron in positron emission tomography (PET). The new technique of detecting the prompt Cherenkov light, produced by absorption of the annihilation photon in a suitable crystal, could considerably improve the image quality. A simple...

In this paper, we will report on the development of a hybrid pixel-waveform (HPWF) readout system for highly pixelated (with a few hundred um pitch size) CZT and CdTe gamma ray detectors. This readout system is based on an energy-resolved photon counting (ERPC) ASIC for reading out the anode pixels, working in coincidence with a high-speed circuitry for sampling the cathode waveform. This...

There is a strong interest in photon counting detectors for applications in the medical, biological and materials research. To meet this interest, we are developing a novel high-spatial resolution photon counting detector capable of detecting low energy gamma rays using solid-state photomultipliers (SSPM). SSPMs are used as gamma ray detectors by coupling them to scintillators, where the lower...

In recent years, Silicon Photomultipliers (SiPMs) attracted lot of interest as a replacement for photomultiplier tubes (PMT’s) due to their ruggedness, compactness or insensitivity to magnetic fields. Other advantages of solid state detectors are their low operating voltage, low power consumption and large scale fabrication possibilities. However, conventional analog SiPMs still do not exploit...

We have investigated the timing resolution and spacial resolution of a pair detector which consists of a silicon photon sensor named MPPC and a newly developed fine silicate scintillator name d LFS. The timing resolution was measured to be 96ps in FWHM extracted from the photon detection time difference of two detectors. This indicates significant progress of the development of TOF...

Molecular imaging of small animals with PET demands high detection efficiency (DE). PET detectors consisting of monolithic scintillators coupled to position sensitive photo-detectors can yield high DE by eliminating detection-inactive space. Silicon photo-multipliers (SiPMs) are compact photo-detectors with high gain, high photon detection efficiency (PDE) and fast response, and there is...
