For routine quality control purposes, many institutions select the Standard SPECT Phantom (Model ECT/STD/P). This is an all-around, general purpose, medium performance model. Its cold rod insert has rods from 6.4 to 16.0 mm and the spheres are 12.7 to 38 mm. For higher resolution, we offer the Deluxe Phantom (Model ECT/DLX/P) and for even higher resolution, is the Ultra Deluxe Phantom (Model ECT/U-DLX/P). For legacy systems or those with generally poor performance, we offer the Benchmark Phantom (Model ECT/BEN/P). The cold rods in its insert range from 9.5 to 25.4 mm and the 6 spheres are 12.7 to 38 mm Please note that when you purchase a “QC” phantom of the circular cylinder type, you receive a cylinder with cover plate and the insert of your choice. If you wish to add to your imaging options, you can purchase only the inserts (rods or spheres) and use your existing cylinder. Note that some of our other phantoms will have a single insert that is available. Please see our Products page see the full line of phantoms and options for each particular one. The “QC phantom” line is only part of our offerings. Some phantoms are designed for evaluating neurological studies (brain phantom models include 2-D, 2-D multi-compartment and 3-D versions), torso phantoms, elliptical QC phantoms, a NEMA phantom and cardiac phantoms. We also supply a wide array of inserts and accessories, and a series of phantoms and inserts for super-high resolution “small animal” scanners. So, please look through our catalog to find the phantom that you think best suits your needs. Of course, if you want help deciding or just have questions in general, please contact us.
