MicroPET PSF
The description you provided seems to be detailing a set of test objects, possibly for medical imaging purposes, that consists of cylinders made from different Tissue Equivalent Materials (TEMs). Each cylinder represents a specific tissue type, and the materials listed include:
- LN 330 (lung inhale): Material mimicking inhaled lung tissue.
- LN 450 (lung exhale): Material mimicking exhaled lung tissue.
- AP 7 (adipose): Adipose tissue equivalent material.
- WT 1 (water): Water equivalent material.
- 50mg/cm3 HA (trabecular bone): Trabecular bone equivalent material with a density of 50 mg/cm³.
- 1200mg/cm3 HA (cortical bone): Cortical bone equivalent material with a density of 1200 mg/cm³.
Each of these materials is represented by a pair of cylinders. In each pair, one cylinder is solid, and the other has a central 0.75mm diameter hole.
