Source TankMade of acrylic, 8.5 inch OD x 8 inch ID x 12 inch long. Resealable, with fill and drain ports. Provides background activity when filled with the desired 99mTc-and-water solution and includes support blocks
“Cold” Lesion Insert7.88 inch OD x 3 inch thick. Contains seven plastic rods; each is nominally 25% larger than the next smaller size. Rod diameters are 5.9, 7.3, 9.2, 11.4, 14.3, 17.9 and 22.3 mm. Plastic spheres of the same diameters mounted on metal rods, (supplied) can be attached to this insert. The rods and spheres displace the radioactive solution in the source tank, thereby creating “cold” lesions. Exponential size gradations allow quantitative resolution measurements
Linearity/Uniformity Insert7.88 inch OD x 2 inch thick. Has a crossed grid of cutout channels in an acrylic block. Scan should show these channels with zero curvature and uniform intensity
“Hot” Lesion Insert7.88 inch OD x 2.5 inch thick. Contains eight pairs of holes drilled through a solid acrylic block. Hole diameters are 4.7, 5.9, 7.3, 9.2, 11.4, 14.3, 17.9 and 22.3 mm. The diameter of each pair increases nominally by 25% over that of the preceding pair. The solid block creates a “cold” field in which the solution-filled holes appear as “hot” lesions
