ULTRASONIC FREQUENCY-SCANNING ECHO STEREOMETER Russian patent published in 1997 - IPC

FIELD: medical equipment, in particular, in traumatology and orthopedics for diagnosis of the condition of the bone tissue. SUBSTANCE: ultrasonic frequency-scanning echo stereometer uses transmitting and receiving ultrasonic diagnostic heads, amplifier, pulse generator, analog-to-digital converter, whose input is connected to the amplifier output, control computer, whose group of inputs is connected to the group of data outputs of the analog-to-digital converter; the first output of the control computer is connected to the input of the pulse generator; set pulse counter, whose input serves as the second output of the control computer; permanent storage , whose group of inputs is connected to the group of digital outputs of the set pulse counter; counter with parallel code loading, whose first parallel digital inputs are connected to the group of outputs of the permanent storage, and the second input serves as the pulse generator output; loading pulse generator whose first input is connected to the pulse generator output, the second input - to the output of the counter with parallel code loading, and the output to the third input of the counter with parallel code loading; repetition-rate scale-of-two circuit, whose input is connected to the output of the counter with parallel code loading; the second amplifier, whose input is connected to the output of the repetition-rate scale-of-two circuit, and the output - to the transmitting ultrasonic diagnostic head. EFFECT: expanded range of picked off information. 1 dwg
