Electronics Engineering

In the field of biomedical ultrasound, innovative ultrasound systems are often required to solve complex questions. Those systems are on the one hand especially adapted to the customer's application and offer on the other hand the greatest possible degree of freedom in setting options and access rights.

By using individual multiplexer solutions, the "DiPhAS" ultrasound research system can be quickly and easily adapted to transducers with up to 1024 elements.

In applications such as volumetric imaging, transducers are used with significantly more elements than channels provided by the excitation and digitizing electronics. A high-precision synchronization circuit enables parallel operation of several ultrasound systems for simultaneous control of up to 1024 transducer elements.

n addition to classical diagnostics, ultrasound is also used for therapeutic purposes, in particular to combat tumors. This involves bundling high-intensity ultrasound waves in order to heat and destroy tissue in a targeted manner (HIFU). An important area of application for this procedure is, for example, the treatment of prostate cancer.

High temporal and spatial resolution ultrasound imaging, which is used in preclinical research to study organs and tissues in small animals, requires advanced multi-channel ultrasound systems that can digitize and process analog signals at very high frequencies.

Single-channel ultrasound systems are optimized for a frequency range between 1 and 35 MHz. Due to their high resolution of details, the imaging systems are used in the medical field for the examination of fine skin structures as well as in the imaging of teeth. By using a multiplexer solution, up to 128 transducer elements can be addressed.

Miniaturized systems are key to mobile ultrasoundapplications like in emergency medicine. We offer two lines of develoment basing on an ultrasmall 8-channel and a scalable multi-channel electronics.
