Key differences between a CZT gamma camera and a CsI imager

Signal detectors are a key component of any medical imaging technology. Many gamma cameras still in use today utilize technology that is more than 50 years old – the Anger-based analog technology. However, more modern options are available with solid state technology. Solid state comes in two main formats: either

Improving Sensitivity and Specificity with Attenuation Correction

Sensitivity and specificity are statistical measures of the performance of a diagnostic imaging test. Sensitivity, which is also referred to as the true positive rate, is a proportionate measure of patients who are accurately identified as having a specific condition. Conversely, specificity, also called the true negative rate, measures the

Cesium Iodide: The Future of Solid State Imaging

What is Solid State? Surprisingly, the majority of gamma cameras still used in nuclear medicine today utilize Anger-based technology; vacuum tubes and hygroscopic sodium iodide (NaI) crystals, technologies that are now more than 50 years old. In response to the demands for better sensitivity and high energy resolution, a new
