Abstract
An ultrasound bone densitometer employs transmitted ultrasound and laser stimulated ultrasound to provide a more complete measure of bone health. Sources of error including secondary laser stimulation, signal dependency on direction of laser light travel, registration, and signal chain noise are addressed in the construction of the densitometer.
Claims15
An ultrasound bone densitometer comprising:
- a first and second laterally opposed ultrasound transducer for transmitting an ultrasound signal through a bone;
- a light source movable between a first position in a region between the bone and the second opposed ultrasound transducer and a second position displaced from the region between the bone and the second opposed ultrasound transducer;
- the light source operating in the first position to direct the light beam along an axis through the bone;
- and
- a controller for controlling movement of the light source and activation of the light source and second ultrasound transducer and for collecting data from the first ultrasound transducer.

An ultrasound bone densitometer comprising:
- a first and second laterally opposed ultrasound transducer for transmitting an ultrasound signal through a bone to make a first ultrasound measurement;
- a light source operating to direct the light beam along an axis in a first direction through the bone at a first time to make a second ultrasound measurement and to direct the light beam along the axis in a second direction through the bone at a second time to make a third ultrasound measurement;
- and
- a controller for combining the ultrasound measurements to provide an output.

An ultrasound bone densitometer comprising:
- housing providing a cavity for receiving and supporting a patient foot therein;
- a first and second laterally opposed ultrasound transducer for transmitting an ultrasound signal through a bone in the patient's foot;
- a light source positioned to direct the light beam along an axis through the bone;
- and
- a controller for controlling movement of the light source and activation of the light source and second ultrasound transducer and for collecting data from the first ultrasound transducer,
- wherein inner surfaces of the cavity provide a reflectivity of less 20% in a range of 690-950 nm.

- a first and second laterally opposed ultrasound transducer for transmitting an ultrasound signal through a bone;
- a light source operating to direct the light beam along an axis through the bone;
- and
- a controller for controlling movement of the light source and activation of the light source and second ultrasound transducer and for collecting data from the first ultrasound transducer;
- and
- further including a housing providing a turntable supporting a cavity for receiving and supporting a patient foot therein with the bone positioned between first and second laterally opposed ultrasound transducers at either of two positions having a respective 180° rotation about a vertical axis with the housing rotated on the turntable.
