WEK-N3L NEMA SPECT Three-Line Source Phantom

WEK-N3L NEMA SPECT Three-Line Source Phantom Details：

1. Radioactive Source Distribution

The radioactive sources consist of a set of three wire sources with an inner diameter < 1.2 mm

and a length of not less than 7 cm, distributed as shown in Figure A.1. The three-wire source

phantom is measured in air, with the same activity in each wire source.

Imaging is performed in two orthogonal directions within a width range of 2 cm to 4 cm centered on the wire source axis.

The three-wire source phantom is placed at the center of a cylindrical phantom with an inner

diameter of 190 mm and an inner height of 200 mm, and the cylindrical phantom is filled with activity in water.
