Ultrasonic Echoscope GS200i

High-resolution ultrasonic measurement system based on the GS200 (article no. 10400) extended by an imaging module for ultrasonic measurements using single-element transducers and an ultrasonic array transducer, delivery includes ultrasonic array transducer, manual, power cable, USB cable, software

The ultrasonic echoscope GS200i is a high-resolution ultrasonic measurement system based on the GS200 (order no. 10400). With this device ultrasonic measurements can be made with the single-element transducers (order no. 10151, 10152, 10154) and ultrasonic images can be produced using the B-mode and M-mode methods with an ultrasonic array transducer.The ultrasonic transducer that is part of the scope of supply possesses an array of 64 convexly arranged individual elements. For the controlling of the array transducer and the recording and analysis of the signal, a separate extension module is integrated into the device.This module and the array transducer are directly controlled from the PC. The supplied measurement software GS-EchoView possesses an additional programme mode via which the adjustment of the measurement parameters (frequency, transmission and reception power, measurement and focal ranges, TGC) and typical parameters for signal and image processing (dynamic range, rejection, image improvement, speckle reduction, contrast, brightness) and the actual conducting of the measurement takes place.Two ultrasonic phantoms are available for experiments using the expansion module:- a test phantom (order no. 10420) with structures that allow the examination and visualisation of physical factors and phenomena of the propagation of ultrasound (sonic time of flight, reflection, acoustic attenuation, sound frequency, axial/lateral resolution, sound field) and- a fetal phantom (order no. 10430) with a fetometrically measurable foetus model.With this equipment, experiments can be created for medical-technical and medical training that relate to both fundamentals and application.

Messsoftware im A-Bild-Modus

Measuring software in A-Mode

The GS200 echoscopes are delivered with the new measurement software GS-EchoView (Windows and higher). The programme interface is clearly divided into three areas: measurement parameters, measurement diagrams and device and status information.The general and special (dependent on the measurement mode) framework conditions for a measurement and its analysis and imaging are specified via the measuring parameters (sampling rate, measurement range). After the start of measuring, the programme controls and/or triggers the echoscope. The measurement data obtained are automatically called and processed by the programme.The measurement results are centrally presented in the form of diagrams. Depending on the measurement mode, different diagrams can be shown, or hidden, next to each other for the analysis and presentation of the measurement data.

Measuring software in A-Mode

In the A-Mode, for example, the measurement signal of an amplitude scan is shown as a time-of-flight signal (or depth-of-field signal) in the A-scan diagram. In parallel with this, the TGC setting can be displayed in a second diagram. In addition, two more diagrams can be shown that allow a frequency analysis of the US signal by means of Fast Fourier Transformation (FFT) and a Cepstrum analysis of the FFT spectrum.The diagrams have measurement cursors for reading off individual values and toolbars for further zoom, saving and adjustment functions.In addition to the A-mode, measurements can also be carried out in the following measuring modes:B-Mode: generating of 2-dimensional US sectional images (B images) hand-operated with a single-element transducer,M-Mode: recording of the chronological sequence of moving reflective layers using the time-motion method,CT-Mode: computer tomography ultrasonic examinations, mechanically operated B-image scans or sound field scans.On the right-hand side of the programme window, device information such as operation mode, transmission level, gain, configuration of the probe connections and status information of the software are shown in a clear fashion.
