An Approximate Method for Linear Signal Decomposition in Gammaray Tracking Detectors
Abstract
An approximate method for signal decomposition in gammaray tracking detectors is presented, based on Singular Value Decomposition (SVD). With this algorithm, the CPU time scales linearly with the number of possible interaction sites for any number of interactions per gamma ray. The method is also robust to uncertainty in the signal start time, and is applicable to any gammaray detectors with highly segmented crystals, as well as any inverse problem that can be reduced to a search among a countable set of precalculated forward solutions.

GammaRay Tracking Detectors: Physics Opportunities and Status of GRETINA/GRETA
Gammaray tracking detectors using highly segmented germanium detectors will give higher efficiency, better peaktototal ratio and much higher position resolution than current generation of detectors. Particularly, the capability of reconstructing the position of the interaction with millimeters resolution is needed to fully exploit the physics opportunities provided by the next generation radioactive beam facilities. This paper presents the basic concepts of tracking, examples of physics opportunities, and the status of the project GRETA/GRETINA. 
Signal Variance in Gamma Ray Detectors  A Review
Signal variance in gamma ray detector materials is reviewed with an emphasis on intrinsic variance. Phenomenological models of electron cascades are examined and the Fano factor (F) is discussed in detail. In semiconductors F is much smaller than unity and charge carrier production is nearly proportional to energy. Based on a fit to a number of semiconductors and insulators, a new relationship between the average energy for electronhole pair production and bandgap energy is proposed. In scintillators, the resolution is governed mainly by photoelectron statistics and proportionality of light yield with respect to energy. 
RespiratoryInduced Prostate Motion Using Wavelet Decomposition of the RealTime Electromagnetic Tracking Signal
Purpose: The objective of this work is to characterize and quantify the impact of respiratoryinduced prostate motion. Methods and Materials: Realtime intrafraction motion is observed with the Calypso 4dimensional nonradioactive electromagnetic tracking system (Calypso Medical Technologies, Inc. Seattle, Washington). We report the results from a total of 1024 fractions from 31 prostate cancer patients. Wavelet transform was used to decompose the signal to extract and isolate the respiratoryinduced prostate motion from the total prostate displacement. Results: Our results show that the average respiratory motion larger than 0.5 mm can be observed in 68% of the fractions. Fewer than 1% ofmore »
