摘要： A bone assessment apparatus for obtaining an assessment value E for a bone 12 with good repeatability by simple calculation using the waveform of a signal derived from received ultrasound which has passed through the bone. A transmitting transducer (20) transmits an ultrasound pulse. A receiving transducer (22) receives the ultrasound pulse which has passed through a test sample (10), and then converts the received ultrasound pulse to a signal. An A/D converter (30) digitizes the signal amplified in a receiving amplifier (28). The digitized signal is inputted to a calculator (32) via a transducer controller (26). The calculator (32) calculates the assessment value E for the bone (12) from characteristic values of the waveform of the signal, such as the half-value width of the first positive portion, which are derived from ultrasonic transmission characteristics of the bone (12).

摘要： A bone assessment apparatus for transmitting and receiving measuring waves through a test part of a patient to diagnose the condition of the test part, includes a measuring bath containing a coupling liquid required for precise measurement and an immersion pouch for keeping the test part out of contact with the coupling liquid. The test part is inserted into the immersion pouch in the measuring bath without touching the coupling liquid. Even during the screening of a number of patients the coupling liquid is prevented, from being contaminated by the test parts of the patients and therefore it is not necessary to change the coupling liquid often. The use of the immersion pouch is detected by a detector to correct a deviation in diagnosis data obtained from the received measuring wave on the basis of a specific correction value assigned to each immersion pouch, thereby providing more precise diagnosis data.

摘要： An apparatus for providing assessment indices related to bone strength which are useful in predicting the risk of bone fracture. The apparatus measures the mineral density of bone (BMD) by means of X-rays, while the propagation speed of sound V in the bone and bone thickness d are measured by means of ultrasonic waves. The bone mineral content per unit volume, i.e. the bone volume density .rho., is computed from the bone mineral density (BMD) and the thickness of the bone. An assessment value E is then computed based on V and .rho..
