SMT-03H Ultrasonic Bone Densitometer

Technical Specification

Ultrasonic parameters: BUA (Broadband Ultrasound Attenuation), SOS (Speed of Sound), OI (Osteogenic Index).

Measurement method: Fully dry-type (no temperature control device required) oil capsule probe measurement, bidirectional ultrasound transmission and reception. Radiation-free, suitable for testing various populations (children, pregnant women, adults, and the elderly). Recommended testing age range: 3–100 years.

Measurement site: Heel bone.

Probe: The oil capsule probe uses specialized ultrasound oil as a conductor for measurement. The probe automatically searches for the optimal signal and does not require replacement during the product’s lifespan; it can be used permanently.

Probe frequency: 0.5 MHz ±15%.

Measurement time: ≤25 seconds (actual test: 21 seconds).
Test repeatability: SOS ≤1% (actual test: 0%).
Measurement error: SOS ≤±2% (actual test: 1%).
Test repeatability: BUA ≤5% (actual test: 0%).

Temperature compensation system: Automatically compensates for measurement deviations caused by temperature.

Comprehensive calculation parameters:
Adults: T-score, Z-score, age-matched ratio, adult-matched ratio, OPR (measurement repeatability), OI (Osteogenic Index), SOS (Speed of Sound), BUA (Broadband Ultrasound Attenuation), bone physiological age.
Children: Z-score, BMI (Body Mass Index), height prediction, obesity degree, SOS (Speed of Sound), BUA (Broadband Ultrasound Attenuation), bone physiological age.

Animation playback function: Attracts children’s attention during examinations, making it easier for doctors to complete the procedure.

Device self-check function: Automatically prompts issues during testing, including setup errors, inaccurate module placement, and correct positioning of the test site.

Case database management system: Automatically records, queries, categorizes, and backs up data. Measurement results can be exported in formats such as EXCEL, JPG, PDF, and DOC.
