If you want to purchase a SPECT cardiac camera, you have several options to choose from. These cameras are generally equipped with CZT crystal detectors and have the ability to capture multiple images simultaneously. These images are stored in list-mode and can then be analyzed to produce different reconstructions. Spect cardiac cameras also allow doctors to perform gated exams that include SPECT and ECG recordings simultaneously. These exams are designed to investigate cardiac function and allow doctors to extract different parameters that can be used in a diagnosis.

GE
The GE czt cardiac camera has an enhanced imaging feature and improved spatial resolution. The camera’s new technology also provides better contrast and count sensitivity. It also has improved collimation systems to allow better image quality. The camera can now measure cardiac function parameters as well. Its main parameters include count sensitivity, spatial resolution, and image contrast as a function of noise level.
The CZT cardiac camera offers a wider table and an increased field of view for improved patient comfort. The detector also features device-less Alcyone Motion Detection and Correction (AMDC), which helps to reduce motion and produce clear images. The camera also offers a novel multi-pinhole collimator design, which combines a dynamic acquisition method with coronary flow reserve, CFR, and absolute myocardial blood flow (AMBF) to provide a better view of the heart’s anatomy.
Siemens
Siemens’ Ge CZT cardiac camera uses a proprietary HD detector and Autoform collimators to produce images of superior quality. The camera has high sensitivity and is rated highly by MD Buyline. The camera’s wide field of view and sensitivity allow for high-resolution images.
The camera’s resolution is approximately five times higher than the Anger camera. Its pixel size is about two millimeters smaller than that of the Anger camera. Its reconstruction algorithm converged more slowly compared to the Anger camera. This could be attributed to the different collimation methods used in the two cameras.
The Ge CZT cardiac camera has high sensitivity and is suited for use in MRI and CT. The camera’s sensitivity is further enhanced by the use of a semiconductor detector, enabling shorter scan times and reduced tracer doses. These features result in increased image quality and sensitivity, while reducing patient discomfort and radiation exposure.
Imarad
Siemens and GE have purchased minority stakes in Imarad Imaging Systems. This action furthers their relationship with Imarad, which developed a CZT-based large-field gamma camera for nuclear medicine imaging. While the joint project officially ended in 1999, the technical relationship between the two companies has continued, says Imarad CEO Michael Schnitzer. Two years ago, GE acquired Imarad’s early CZT technology.
The camera has a CZT crystal detector and can record SPECT images as well as ECG images. The raw data can be used to perform various reconstructions. It can also be used to perform gated exams, where ECG and SPECT recordings are conducted simultaneously. The main purpose of these gated exams is to study the function of the heart. The data can be used to help doctors determine whether there are any issues with the heart.
Discovery NM/CT 670
The Discovery NM/CT 670 CZT combines next-generation SPECT technology with proven multi-slice CT to deliver exceptional image quality and efficiency. The system is compatible with any supported SPECT and CT protocols and has advanced robotics that can significantly reduce scanning times. Moreover, it offers responsible dose management for both NM and CT imaging.
The Discovery NM/CT 670 CZT is a hybrid imaging system from GE Healthcare, a $17 billion unit of General Electric Company. It combines the latest advances in Nuclear Medicine detectors and GE’s BrightSpeed Elite16 slice CT to improve both imaging quality and workflow.
It features a high spatial and energy resolution. Its count rate is excellent. Overall, the Discovery NM/CT 670 CZT is an excellent choice for clinical use.
