Hoffman Multi-Compartment 2-D Brain Phantom™
SPECT and PET Research, Training, Performance

Main Features:

Anatomically correct - varying isotope uptake ratios - simulation of the activity distribution in a flow or metabolic image of normal and abnormal human brain*
Seven (7) gray-matter compartments that may 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

Main Applications:

SPECT and PET applications include research, system performance measurements, and optimization of imaging protocols, image interpretation, and training
