“…Furthermore, CsI:Tl shows a poor match with bialkali photocathode light response: This determines a low number of photoelectrons and as a consequence, a poor energy resolution. The availability of NaI:Tl pixelated crystals allows to obtain a higher light output with an energy resolution close to 14% at 140 keV photon energy 1, 14 and a higher light spread, as produced by the additional glass window needed to protect the highly hygroscopic crystal. It became very useful to identify crystal pixels located on the tube cracks.…”

“…This scintillation array with 2 mm crystal pitch was chosen to realize a com-pact gamma camera with large FoV to fully image a breast in scintimammography. 14 Unfortunately, due to machining concerns, the smallest pixel pitch available is limited to 1.2-1.4 mm, 1,15 with a needed reduction in crystal length down to 5 mm ͑lower detection efficiency͒. Starting from such results a number of authors proposed the use of continuous crystals as a strong competitor of scintillation arrays for spatial resolution values close to 1.5-2 mm.…”

“…Recently there has been a growing interest in compact and high resolution small gamma cameras, which are used for applications ranging from small animal imaging to scintimammography [1]- [3]. Several groups have been working on the development of the small gamma cameras using position sensitive photomultiplier tubes (PSPMT) and pixellated scintillator crystals [2]- [6].…”
