AOS-100
is a powerful tool for the assessment of fracture
risk in Osteoporosis. |
| Osteoporsis
is a metabolic bone disease, and it is a condition
in which the amount of bone tissue is so low and
bone strength is so weak that the bones easily
fracture in response to minimal force. The hip,vertebra
and forearm are typical regions of bone fracture.
The most common and serious complications are
caused by hip fractures, which affect the quality
of life. |
|
Routine
screening for the detection of osteoporosis in its early
stage is in the spotlight as the early detection would
allow early intervention and could prevent some fractures
and complications associated with osteoporosis.The adage
"An ounce of prevention is worth a pound of cure"
has special relevance to osteoporosis. AOS-100, a compact
and easy-to-use ultrasound bone densitometer, can assess
the risk of bone fracture by measuring the condition
of the calcaneus (heel bone). It provides safe, very
quick and precise measurements, employing Aloka's state-of-the-art
ultrasound technology.

Calcaneus
(heel bone) is predominantly trabecular bone that
reflects the metabolic change earlier than cortical
bone. Also, it is a weight bearing site and easily
assessible site. Therefore, calcaneus is an excellent
site for bone status evaluation.
Calcaneus (heel bone) is
measured with a subject's heel secured with the
probes on the foot stand, not necessary to use
water bag or to immerse subject's foot in water.

AOS-100
provides thress different ultrasound parameters
available for the assessment of fracture risk.
SOS reflects bone density, TI relates to bone
mass and OSI shows overall bone status, especially
relating to elasticity and density of bone. Also,
those ultrasound parameters are highly correlated
to lumbar BMD obtained by the DXA instrument. |
|
Speed
of sound (SOS)
Speed of ultrasound pulses transmitted from one
transducer to the other through the heel of the
subject.
Transmission Index (TI)
A newly developed parameter defined as the full-width-half-maximum
of the first positive peak of the received waveform.
Osteo Sono-assesment
Inedx (OSI)
A calculated ultrasound parameter combining SOS
and TI (OSI=TI x SOS²). |

There
is no fear of radiation exposures, which is a
big advantage fo both subjects and operators.
AOS-100 can be comfortably and repeatedly used
even for pregnant women and children. Also, it
is not always require licensed operators and a
special room for examinations.
|
|
|
|
| No water is required.
It is not necessary to supply water and to control water
temperature as well as to replace water between subjects.
Also, the subjects are not required to immerse their
foot into water. Therefore, preparation of the subject
can be completed in a short time and the examination
can be preformed hygienically and easily. |
|
|
Measurement time is only less than 5 seconds. It does
not take more than two minutes until you get the printed
results for one subject. AOS-100 greatly reduces the
burdens of examinations for the elderly and children.
Also, it will be an efficient tool when measuring a
number of subjects within a limited period of time,
such as a mass screening program. |
|
|
| AOS-100 has been designed
to fit in the physician's office and clinics. Also,
it is transportable, allowing you to examine the subject's
heel in almost any location and calculate bone strength
with ultrasound. |
|
|
Easy to use and rich
software (Windows® 95/98 OS)
Microsoft Windows® 95/98 OS based software allows
you to use the AOS-100 easily. Rich software functions
are provided in the standard configuration, such as
package input of subject data, measurement result printout
of measurement results in a text file format, display
of trendgram (trend chart).
|
|
|
AOS-100 can be used for the subjects with a foot size
longer than 18cm. Children can also be easily measured. |
|
|
|
|
 |
AOS-100 adopts
the open structure design and uses a datachable
foot stand, which makes it easier to apply an
echo jelly to the probes and to ascertain the
heel fitting condition as well as to clean the
foot stand. |
