In the beginning we had only 20 MHz Systems, today the range goes upto 100 MHz, which gives us a resolution down to 16µm in the skin. Since 2001 we also offer a real Windows System with all advantages of Windows. The already large range of functions has been stretched out in the Windows Version. With the easy to handle window technology the DUB for Windows is easy to operate.
And now we can offer the DUB6100 as an OEM-Version. Which gives you the possibility to include a high frequency ultrasound imaging system in an existing PC housing. Controlled by our GRIDUB for Windows Software.

The property of the ultrasound waves is very effective in the ultrasound diagnostic. The waves are able to get through the substance. During the spreading, at the borders of tissues with different ultrasound attributes, the waves can be reflected (partly, or if the differences are very great, completely).
The reflected waves will be transformed into electric impulses and displayed on a monitor.
Two methods are used for the reproduction of the images:
1. A-Mode: Proportional to the intensity of the received waves, adequate amplitudes will be presented.
2. B-Mode : The Transducer, placed in the Applicator, will travel over the examination object. During this time several A-
Mode images will be taken and afterwards collected into one two-dimensional image.The x-axis of the image complies to the spreading into the depth. In fact the time the ultrasound travels from the transducer to the tissue and back is proportional to the depth.

The important numbers to define tissue properties are the ultrasound velocity, the ultrasound impedance and the sound resistance. The ultrasound image with a good contrast results in different sound resistance's.
It is important, that the ultrasound-system has a fine and high resolution. That means that it is possible to distinguish thin structures in axial direction (direction of the sound) and lateral(side by side). For a high axial resolution it is needed to have short ultrasound waves. The supposition therefore is the highest possible frequency of the sound wave.
Momentary the systems which are used in the Dermatology contain a frequency area from 7,5 MHz - 75 MHz.
On the one side the limitation depends on the technical possibilities. On the other side the absorption in the tissue sets the upper limits. As the frequency is increasing the absorption grows linear. In compact tissues it grows quadratic, which will lower the penetration depth. So, that it is impossible to present the deeper structures.

Basic-principle:
The ultrasound impulse is passing through the tissue-structure with the sound velocity which is characteristic to this structure.At that time a reciprocal-action with the tissue of the structure arises. The utilization of the received signals (Amplitude and Running Time) is admitting conclusion inferences of the inner quality of the tissue-structure, without destroying the same.Wave types and wave spreading:
In the longitudinal wave the molecules (atoms) are swinging parallel to the spreading direction.
Compression- and pulling powers are working in it and therefore it's also called compression wave. It is the real sound wave, which is transmitting the sound through solid and liquid substances. In solid substances the transversal wave will be found, too. But the molecules are swinging vertical, transversal and not into the spreading direction.
The sound velocity is a constant, which depends on the tissue. In combination with the used frequency, the result is the wave length.

Technical realization
The sender of the system generates high voltage impulses, which will be send to the transducer inside the applicator. At the same time the transducer will move inside the applicator a specific distance. In this case we are working in the pulse/echo mode which means that the same transducer sends and receives the ultrasound signals.
With a high quality and high speed A/D-converter the electrical impulses which comes back from the transducer will be digitized. With a sampling rate of 100 MHz or more and a dynamic of 8bit the system will give a clear reproduction image of the signals. These information is used for viewing a A-, B-, C- or 3D-scan.
Ultrasound impulses
A piezoelectrical converter/transducer (ceramic,folio) is used to create the ultrasound impulses. This transducer converts electrical energy from the sender into ultrasound waves. Mechanical damping inside the transducer creates a smooth swinging ultrasound impulse. The frequency of the impulse is defined by the thickness of the transducer element, the impulse length and the frequency spectrum.

Sound field
The form of the ultrasound field depends on the reflection of the tissue, the thickness of the element, the frequency and the sound velocity of the tissue.
Completing the sound area with sensitivity of circular reflectors it creates the sonogram.In the far field a bell-shaped lateral distribution of the sound pressure will be produced. The descent of the sound pressure to 50% defines the beam diameter.
Reflection and Refraction
A sound wave which hits a border line splits in two parts, one who will be reflected and one that will go through . This will change amplitude, reflection and permeability fact.
R = reflection fact
D = permeability fact
Z = acoustic impedance
c = velocity of sound
r = compactness
