Handheld Bone Densitometry Configuration on Development of Bone Model Density Testing

Handheld bone densitometry is a bone model density testing system using ultrasonic spectroscopy with pulseecho method. In this study, we characterize a handheld bone densitometry configuration that uses a bone model made of PLA (Polyactic Acid) as the test object. This research also includes the use of a specially designed bone holder to hold and stabilize the bone model during measurement. The bone holder aims to improve the consistency of measurement results and reduce variability. Experiments were conducted using a handheld bone densitometry equipped with an ultrasonic transducer. Tests were conducted on TGC (Time Gain Compensation) configuration and ultrasonic wave frequency to obtain precise and accurate data on the density of the PLA bone model. The results of this study show that the use of PLA bone models as test objects for handheld bone densitometry has the potential for further development so that it can become a density measurement tool in human bones. By using a bone model holder, bone density measurements become more consistent and reliable. Proper TGC settings also affect the accuracy of the measurement results. In addition, the optimal frequency of ultrasonic waves also plays an important role in obtaining adequate data on bone density.
