Overview

Bone density measurement and evaluation phantomis the diameter80 mm, 60 mm high cylinder. I, II, III, and IV are small cylinders with a diameter of 20 mm, a length of 40 mm, and different densities. Among them, the centers I and III are on the same straight line, the centers II and IV are on the same straight line, and the two straight lines are perpendicular to each other. The centers of the small cylinders I, II, III, and IV are on a circle with a diameter of 40 mm. The basic material of the phantom is a soft tissue equivalent material (polyurethane resin) with a purity of more than 99%. The material of the I, II, III, and IV regions is hydroxyapatite (HA), and the corresponding bone density is 50 mg/cm respectively.³、100 mg/cm³，200 mg/cm³，300 mg/cm³, see pictureA.1. Meets the "YYT 1466-2016 Pharmaceutical Industry Standard of the People's Republic of China".

Note: Given in this standardBone density measurement and evaluation phantomFor recommended phantoms, manufacturers may choose other materials to provide equivalent bone density. Additionally, the geometric design of the phantom can also vary. Any phantom that is equivalent in achieving bone density evaluation can be used, but detailed description of the phantom is required.。
