Resolution (Derenzo) Phantoms
Phantech has several different Derenzo patterns for preclinical SPECT applications. Each one features our patented linear flow technology (Patent US9625584B1) that makes filling a breeze, prevents bubbles, and reduces the amount of radiation required to fill the hole pattern. This results in a safer phantom that produces higher quality images. We have several standard hole patterns with holes ranging from 0.7 mm to 2.5 mm. We can also create custom patterns if the standard options do not quite fit your individual needs.
Phantech uniformity phantoms are designed to perform quality control and calibration on field uniformity, normalization and quantification calibration of SPECT scanners. They are constructed to ensure a perfectly homogenous concentration by preventing air bubbles and sticking of radioactivity to the interior surface. Configured in two standard sizes, these uniformity phantoms will allow one to customize protocols and calibrations in order to yield the highest quantitative accuracy for each scanning condition.
Partial Volume Correction (PVC)
Designed for signal recovery of small lesions for preclinical SPECT imaging systems, Phantech PVC phantoms are designed with one continuous channel connecting numerous precise spherical or ellipsoidal volumes, these PVC phantoms allow for the easy and automated generation of a recovery coefficient (RC)-based PVC curve. Our PVC phantoms are available with several different outside diameters (27mm, 34mm, and 49mm) and sphere sizes to accommodate different bore sizes and scanner specifications. Each PVC phantom also features a separate fillable "warm" region to simulate background tissues.
SPECT-IQ (Image Quality) Phantoms
Phantech has economical phantoms that adhere to the National Electrical Manufacturers Association (NEMA) standards. Assembled with three main pieces and associated hardware, the SPECT-IQ is a scaled down version of the NEMA NU-4 2008 for SPECT scanners (as detailed in E.P. Visser et al. 2011, Nuclear Instruments and Methods in Physics Research A). The SPECT-IQ standard phantom features three fillable regions that allow the assessment of SPECT scanner image quality (IQ).
