Neural Networks (NN) are very efficient to determine the entrance point of a gamma incident on a scintillator block. This paper presents results on the robustness of the spatial resolution as a function of the random fraction in the data, temperature and HV fluctuations. This is important when implementing the method in a real scanner. Measurements were done with two Hamamatsu S8550 APD arrays, glued on a 20 {\~A}— 20 {\~A}— 10 mm3 monolithic LSO crystal block.}, language = {en} } @article{StreunLarueParletal.2009, author = {Streun, M. and Larue, H. and Parl, C. and Ziemons, Karl}, title = {A compact PET detector readout using charge-to-time conversion}, series = {2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC)}, journal = {2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC)}, publisher = {IEEE}, address = {New York}, isbn = {1082-3654}, pages = {1868 -- 1870}, year = {2009}, abstract = {The readout of gamma detectors is considerably simplified when the event intensity is encoded as a pulse width (Pulse Width Modulation, PWM). Time-to-Digital-Converters (TDC) replace the conventional ADCs and multiple TDCs can be realized easily in one PLD chip (Programmable Logic Device). The output of a PWM stage is only one digital signal per channel which is well suited for transport so that further processing can be performed apart from the detector. This is particularly interesting for large systems with high channel density (e.g. high resolution scanners). In this work we present a circuit with a linear transfer function that requires a minimum of components by performing the PWM already in the preamp stage. This allows a very compact and also cost-efficient implementation of the front-end electronics.}, language = {en} } @article{BlassUibel2009, author = {Blaß, Hans Joachim and Uibel, Thomas}, title = {Bemessungsvorschl{\"a}ge f{\"u}r Verbindungsmittel in Brettsperrholz}, series = {Bauen mit Holz}, volume = {111}, journal = {Bauen mit Holz}, number = {2}, publisher = {Rudolf M{\"u}ller}, address = {K{\"o}ln}, issn = {0005-6545}, pages = {46 -- 53}, year = {2009}, language = {de} } @article{RingbeckProfittlichSchaller2009, author = {Ringbeck, Thorsten and Profittlich, Martin and Schaller, Christian}, title = {Kameras f{\"u}r die dritte Dimension : PMD-Technologie erm{\"o}glicht neue effiziente Anwendungen in der Industrie und Medizintechnik}, series = {Optik \& Photonik. - 4(2009), H. 3}, journal = {Optik \& Photonik. - 4(2009), H. 3}, publisher = {Wiley - VCH}, address = {Weinheim}, issn = {1863-1460}, pages = {30 -- 33}, year = {2009}, abstract = {Flederm{\"a}use orientieren sich extrem schnell auch in absoluter Dunkelheit.
