This stability (agar) phantom consists of a cylindrical phantom and agar material inside. Using this phantom a Signal to Noise Ratio, Signal Fluctuation to Noise Ratio, drift, and other imaging measures over a 100-volume or 200-volume fMRI scan can be performed. The agar phantom has characteristics similar to the T2 measures of a human head, but provides no change in signal. The T1 and T2 characteristics of the agar phantom at 3T are ~900 ms T1 and 30 ms T2. -
Rectangular MRI phantom simulating attenuation of the human spine. -
The Pro-NM AutoFlood is dedicated for weekly inhomogeneity and sensitivity control and acquisition of correction matrices, according to revised Guideline on Radiation Protection in Medicine. -
A simple phantom the quality assurance of geometric distortion and spatial resolution of gamma cameras. Array of holes, which when filled with activity, allows to measure point-to-point distances and Point Spread Function (PSF) - spatial resolution - at each point and its homogeneity across the entire Field of View. -
This scatter phantom simulates in-vivo forward and backscatter characteristics of 99mTc gamma rays for the extrinsic measurement of a scintillation camera’s deadtime. The phantom produces a spectrum typical of that observed from 99mTc in the myocardium. Reference: Ralph Adams, Gerald J. Hine, and C. Duane Zimmerman, “Deadtime Measurements in Scintillation Cameras Under Scatter Conditions Simulating Quantitative Nuclear Cardiography,” The Journal of Nuclear Medicine, 19 (1978), 538-544. -
Flood phantoms provide a simple and efficient means of obtaining optimum camera performance with respect to uniformity of response over the entire crystal area. These phantoms are designed to be filled in horizontal position, thus preventing slight bulging caused by water pressure during vertical filling. Therefore, better uniformity in distribution of activity can be achieved. -

The Phantom designed for a simple and cost effective verification of image alignment and distortion in hybrid scanning systems like PET/CT or NM/CT. It consists of a cylinder that can be filled with a variety of fluids. Several non-parallel rods of varying diameter and at certain angles in relation to the phantom’s axes run the entire length of the cylinder. -
Main application of Pro-NM NEMA 94 is PET acceptance testing with NEMA standard. Evaluation of count rate, uniformity, scatter fraction, attenuation compensation, and scatter compensation of ECT systems. -
This SPECT dedicated phantom can be used to produce images similar to those obtained in a whole body tomographic imaging study, with hot and cold lesions and a large cold region representing the lung. -
The phantom for evaluating performance of positron emission tomographs (PET). Recommended for use in the evaluation of reconstructed image quality in whole body PET imaging. -
A phantom for evaluation of spatial resolution of positron emission tomographs (PET). It is used to characterize the widths of the reconstructed image point spread functions (PSF) of compact radioactive sources. It has been designed in accordance with the NEMA Nu 2-2012.
