| 摘要 |
A phantom for a quantitative ultrasound device is provided. The phantom includes a hollow casing, a first acoustic element disposed within the hollow casing, the first acoustic element simulating a broadband ultrasonic attenuation (BUA) of an exemplary bone; and a second acoustic element disposed within the hollow casing, the second acoustic element altering a speed of an ultrasonic signal transmitted through the phantom, the second acoustic element being disposed in-line with the first acoustic element. The phantom also includes a third acoustic element disposed within the hollow casing, the third acoustic element forming an acoustic coupling agent between the first acoustic element and the second acoustic element. A method of fabricating a phantom is also described herein.
