Introducing Sunlight Omnisense® 7000S/8000S

mitted. Audible sound for humans is in the range of 20 Hz to
20,000 Hz (20 kHz). Ultrasound refers to a range of frequencies
that begin at the end of the audible range and extend into the
Megahertz range.

The propagation of ultrasound through a medium, its speed,
dispersion and attenuation of signal strength are strongly influ-
enced by the physical properties of that medium. QUS takes
advantages of these influences to draw conclusions about the
physical properties of bone through which an ultrasound signal
is traveling. Two measures are in common use: the

attenuation

(change in amplitude) of the signal, and the

speed of its trans-

mission

through bone. The latter measure, commonly abbrevi-

ated SOS (for Speed of Sound) is the one used by Omnisense.

While based on the same principle as other QUS devices,
Omnisense is distinct in its unique Omnipath

®

Axial Transmis-

sion; i.e. measurement along the bone axis.

3.2 Omnisense Technology - Omnipath

®

In the frequency range used by Omnisense, an ultrasound signal
travels much faster through the relatively dense, cortical layer
of the bone than through the trabecular layer — approximately
4000 m/s

vs.

1800 m/s. The signal travels through soft tissue

much more slowly than through either type of bone, and propa-
gation through air is practically nonexistent. Omnisense relies
on this fact for its operation.

P

ROBES

Omnisense employs hand-held probes to generate and detect
ultrasound waves. Each probe contains a number of

transducers

,

some of which serve as ultrasound signal generators while others
function as detectors. During measurement, the probe is applied
directly to the skin at the region of interest. In case probe caps are
used, a layer of ultrasound gel is applied between the probe sur-
face and the probe cap. A probe cap is mounted over the probe
measuring surface, with the cap’s front skin in good contact with
