Bone UltraSonic Scanner (BUSS) Clinical Optimization Study

The specific aims of this clinical study are:

• To optimize the data collection technique and establish an examination procedure;
• To collect data necessary for assessing the performance of BUSS sensors;
• To evaluate the probe ergonomic design and participant tolerance to probe application;
• To assess the clinical suitability of the software interface in data collection;
• To adjust the BUSS diagnostic algorithms using dual-energy X-ray absorptiometry (DEXA) data as a "gold" standard in osteoporosis detection and characterization;
• To evaluate BUSS performance including ease of use and consistency.
