Description

The 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.

Software

The GS200 and GS200i echoscopes are delivered with the new measurement software GS-EchoView (Windows 7/8). With this programme, ultrasonic measurements can be carried out with single-element transducers, using the A-mode, B-mode or M-mode methods and also computer tomography ultrasonic examinations (see software description for GS200). An additional programme mode is available for the GS200i with its expansion module for ultrasonic examinations with an array transducer: Imaging.
In imaging mode, ultrasonic measurements can be carried out with the B-mode method with or without additional M-mode scan. The ultrasonic images are shown in the middle of the programme window.
In parallel with the ultrasonic B-image, the amplitude signal can be shown along a single scan line. This way, it is simple to illustrate the step from the actual measurement signal – the ultrasonic signal – to the B-image.
For the carrying-out of a measurement, the transmission power, gain and measurement range can be adjusted, focus areas set and the TGC added over several sampling points through the measurement range.
Typical parameters and methods of signal and image processing such as smoothing and sharpening filters, dynamic range, rejection, speckle reduction, brightness, contrast and gamma correction can be applied and altered in order to investigate their influence upon the measurement results, i.e. the ultrasonic images.
For the analysis of the measurements, lines and ellipses can be generated in the ultrasound B-image in order to measure spacing, lengths or areas and their perimeters.
