A CZT-based blood counter for quantitative molecular imaging. Nuclear medicine cameras using CZT detectors are commercially available. In order to achieve improved image quality for an energy-optimized SPECT scanner, we use a relatively large-detection-area CZT-based detector (20.48 × 20.48 cm 2) with a thickness of 5 mm (thinner than the typical NaI crystal of 3/8 in. Griesmer JJ, Kline B, Grosholz J, Parnham K, Gagnon D. Performance evaluation of a new CZT detector for nuclear medicine: Solstice 2001. The same low energy high resolution collimator was used on each system and the same total counts (250 kcts) were acquired in each image. As a leading producer of solid-state nuclear cameras, Digirad is here to explain what makes a camera solid-state. Conclusions The CZT detector gamma camera allowed us to keep below the DRLs for myocardial perfusion imaging regardless of the patient’s weight. Yusuke Higaki, Masato Kobayashi, Tomoya Uehara, Hirofumi Hanaoka, Yasushi Arano, Keiichi Kawai, Appropriate collimators in a small animal SPECT scanner with CZT detector, Annals of Nuclear Medicine, 10.1007/s12149-012-0681-5, 27, 3, (271-278), (2013). These detectors have inherently be … CZT detector technology for medical imaging To cite this article: ... Nuclear medicine diagnostic applications are growing in search for more disease specific relevant imaging. The CZT detector consists of a semiconducting crystal that is bump-bonded to a large area ASIC and packaged with a high performance data acquisition system. Forty patients referred to SPECT-MPI with clinical indication for evaluation of CAD underwent a 1-day 99m Tc-tetrofosmin pharmacological stress/rest protocol according to the current guidelines of the European Association of Nuclear Medicine.

Two dedicated cardiac CZT detector CZT detector fabrication. Furthermore, the dose of radiation given by our one-day protocol is below the European Association of Nuclear Medicine’s guidelines, which are 400–500 MBq for the first injection and three times more for the second injection. Most nuclear medicine studies require the use of a detector outside the body to measure the rate of accumulation, release, or distribution of radioactivity in a particular region inside the body. Section snippets Collimator-detector model. CZT detector technology for medical imaging. However, the new CZT cameras were also designed to optimize the acquisition and reconstruction processes with original software and collimation systems, leading to a marked enhancement in count sensitivity and spatial resolution, as confirmed by the article by Zoccarato et al,4 in this issue of the Journal of Nuclear Cardiology.
