Hoffman Brain Phantoms

Hoffman 2-D Brain Phantom

The Hoffman 2-D Brain Phantom provides an evaluation of acquisition and reconstruction methods for brain PET and SPECT studies.

The phantom features thickness differences between ventricles, gray and white matter that simulate the radioactivity distribution in a single slice of a brain ECT study. Normal gray-matter:
white-matter:ventricle radioactivity ratio is 4:1:0 (simulated by partial volume effect).

BR/2D/P Hoffman 2-D Brain Phantom $1,180.00

Hoffman 2-D Multi-Compartment
Brain Phantom

This anatomically correct phantom provides varying isotope uptake ratios and simulation of the activity distribution in a flow or metabolic image of normal and abnormal human brain. Seven (7) gray-matter compartments can be separately filled with varying amounts of radiotracer to simulate a variety, of "hot" and “cold" abnormalities. Normal gray-matter:white-matter:ventricle activity, ratio is 4:1:0 (simulated by partial volume effect). Abnormal-gray-matter:normal-gray-matter
activity, ratios can be varied from 0.25:1 to
greater than 100:1.

Hoffman 3-D Brain Phantom

The Hoffman 3-D Brain Phantom evaluates f acquisition and reconstruction methods for brain ECT studies, 3-D reconstruction methods, 3-D attenuation and scatter compensation methods, and 3-D SPECT, PET and MRI registration techniques.

The phantom provides an anatomically accurate simulation of radioactivity distribution for brain SPECT and brain PET studies and distribution of proton density and relaxation parameters for brain MRI studies. It simulates 4:1 uptake ratio (by partial volume effect) seen for normal gray and white matter in flow and metabolic studies. The single fillable chamber eliminates the necessity of preparing different concentrations of radioactivity.

Fillable and solid defects for basil ganglia region are available. Hot and cold defects can be located in the basil ganglia region. The Fillable and solid defects allow the user to determine image shape of the defect.
