Based on the basic theory of two-wave detection method which was formulated in 1990’s by Takahiko Otani, Professor Emeritus of Doshisha University and the patent of HORIBA, Ltd. (Headquarters: Kyoto, Japan), OYO Electric Co., Ltd. started developing this equipment with support of the JST (Japan Science and Technology Agency) in 2001, and successfully completed a prototype in 2004. In 2005, OYO obtained a safety and effectiveness data which was confirmed by a Clinical Trial. In 2009, LD-100 was certified by the MHLW (Ministry of Health, Labour and Welfare) as medical equipment because of its highly positive correlation to X-ray CT equipment.
In 2008, OYO Electric Co., Ltd. was qualified as a "Kyoto Promising SMEs"(*1). Our objective is to popularize the use of this new bone densitometer. In order to achieve our objective, we will work through Industry-Academics-Government cooperation.

Ultrasound bone densitometer LD-100 Product Information
For the first time in the world, LD-100 uses an ultrasonic two-wave detection method to quantitatively evaluate bone density and elastic modulus for practical use.
An ultrasonic densitometer has been successfully commercialized for the first time in the world, which can quantitatively evaluate bone density, elasticity and thickness of cortical bone and cancellous bone that compose human bone.
As this ultrasonic method has enabled quantitative evaluation in osteoporosis diagnosis, this method can be used as a new bone densitometer to monitor the rapid deterioration of bone strength due to drug’s side effects.
Bone density measurement is used to diagnose bone strength, which is deteriorated mainly due to osteoporosis. There are two modalities for measuring bone strength, X-rays and ultrasound, which have different problems. X-ray measurement is capable of calculating bone density and bone thickness, separating cortical bone and cancellous bone, but there is a risk of radiation exposure. In the ultrasound measurement there is no radiation exposure risk. However, the value derived from the ultrasonic velocity and attenuation is not the density itself. So it is unable to evaluate quantitatively the bone density.

So it is unable to evaluate quantitatively the bone density.
For the first time in the world, our new ultrasound-based bone densitometer enables the measurement of density and thickness of each the cortical bone and the cancellous bone, by using a new ultrasonic two-wave detection method without radiation exposure.
In addition, this new bone densitometer is capable of measuring the elastic modulus of cancellous bone, which X-ray method and conventional ultrasonic method are not able to measure.
This new bone densitometer is able to make measurements of the wrist. So it is comfortable for the patient. This bone densitometer can meet the needs in frequently repeated bone density measurements, e.g. to monitor the rapid deterioration of bone strength which is caused by side effects of steroids, and has an extremely high potential for medical applications and Hospitals.
