ÐMeasurement of lepton contamination is achieved across a radiotherapy photon beam and peripheral doses using radiochromic ®lm. An extrapolation technique is used where several layers are suspended in air to measure incident contamination without the eects of phantom scatter. Surface dose was measured as 11% of Dmax for 6 MV beams at central axis and 9% for 10 MV photons for a 10 10 cm ®eld si...
متن کاملBinary vector quantizer design using soft centroids
Soft centroids method is proposed for binary vector quantizer design. Instead of using binary centroids, the codevectors can take any real value between one and zero during the codebook generation process. The binarization is performed only for the "nal codebook. The proposed method is successfully applied for three existing codebook generation algorithms: GLA, SA and PNN. ( 1999 Elsevier Scien...
