The working horse for the detection of photons is the photomultiplier tube (PMT)
which was invented in the RCA laboratories and became 1936 a commercial product.
It is an elaborated device but still, after 70 years, impressing improvements have
been achieved recently. PMTs however have two severe handicaps: they are very
sensitive to magnetic fields and their price is high because the...

Simple theory predicts that the signal to noise ratio in PET can be reduced by an order of magnitude by using
time-of-flight (TOF) information. This reduction can be obtained by improving the coincidence timing
resolution, and so would be achievable in clinical, whole body studies using with PET systems that differ little
from existing cameras. The potential impact of this development is...

A new generation of micropattern gas detectors (MPGD) has been developed, mostly to cover the needs of
particle physics. The excellent performances in terms of two-dimensional localization and rate capability makes
MPGD very attractive for digital imaging of radiation. After a short summary of performances, recent applications
in physics, astrophysics, biomedicine will be presented.

Abstract
Invited Tutorial
Microelectronics technologies play an ever more important role in medical imaging,
both in the imaging devices themselves and in the digital capabilities to enhance and
analyze the image. This trend will continue in the future, and instrumentation
developments in elementary particle physics can serve as a proving ground for new
directions in digital imaging...

Objective: Emission tomography (Single Photon Emission Tomography – SPECT – and
Positron Emission Tomography – PET) offers a great potential for the quantitative
characterization of functional and molecular processes in vivo. Indeed, voxel values in the
reconstructed SPECT and PET images can theoretically be translated into a well-understood
physical quantity, namely radiotracer...
