In this work we present a detection system, based on a CdTe detector and an innovative digital pulse processing (DPP) system, for high\u2010rate x\u2010ray spectroscopy in mammography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>The DPP system performs a digital pile\u2010up inspection and a digital pulse height analysis of the detector signals, digitized through a 14\u2010bit, 100 MHz digitizer, for x\u2010ray spectroscopy even at high photon counting rates. We investigated on the response of the digital detection system both at low (150 cps) and at high photon counting rates (up to 500 kcps) by using monoenergetic x\u2010ray sources and a nonclinical molybdenum anode x\u2010ray tube. Clinical molybdenum x\u2010ray spectrum measurements were also performed by using a pinhole collimator and a custom alignment device.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The detection system shows excellent performance up to 512 kcps with an energy resolution of 4.08% FWHM at 22.1 keV. Despite the high photon counting rate (up to 453 kcps), the molybdenum x\u2010ray spectra, measured under clinical conditions, are characterized by a low number of pile\u2010up events. The agreement between the attenuation curves and the half value layer values, obtained from the measured spectra, simulated spectra, and from the exposure values directly measured with an ionization chamber, also shows the accuracy of the measurements.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>These results make the proposed detection system a very attractive tool for both laboratory research and advanced quality controls in mammography.<\/jats:p><\/jats:sec>","DOI":"10.1118\/1.3512804","type":"journal-article","created":{"date-parts":[[2010,12,1]],"date-time":"2010-12-01T00:17:30Z","timestamp":1291162650000},"page":"6147-6156","source":"Crossref","is-referenced-by-count":34,"title":["High\u2010rate x\u2010ray spectroscopy in mammography with a CdTe detector: A digital pulse processing approach"],"prefix":"10.1002","volume":"37","author":[{"given":"L.","family":"Abbene","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Gerardi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Principato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Del Sordo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Ienzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Raso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,11,8]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0169-2607(94)90127-9"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.598100"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.1928312"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.1318222"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apradiso.2004.09.010"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.1608498"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.2790841"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.597939"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.596686"},{"key":"e_1_2_6_11_1","unstructured":"K.Cranleyet al. \u201cCatalogue of diagnostic x\u2010ray spectra and other data \u201d IPEM Report No. 78 (CD\u2010Rom Edition1997) (electronic version prepared by D.
