Multichannel digitizers
Data acquisition systems with digital signal processing - or digitizers - have been developed to translate physical world signals into digital. Digitizers have application in telecommunication, power, industrial automation, health, aerospace, and scientific research. Current improvements in semiconductor devices allow the development of digitizers with embedded algorithms for use in radar, ultrasound and ionizing radiation detection, especially in Nuclear Medicine, such as Single Photon Emission Computed Tomography (SPECT) and PET. Gaugit is developing a family of digitizers with innovative digital signal processing algorithms for PET applications.
PET technology
Positron Emission Tomography (PET) technology is used in the analysis of biochemical processes in humans and animals. The number of PET applications has been increasing in recent years, comprising cancer diagnosis and cerebral and cardiological studies. PET can detect early-stage tumors, which is not possible in imaging techniques such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Ultrasonography. PET also has preclinical use, as in drugs development and pharmacological studies. PET has received improvements from nuclear instrumentation to enhance image quality and reduce costs
and radiation dose.
Advanced digital electronics
Field Programmable Gate Array (FPGA) based solutions offer many advantages over analog systems, such as improved signal error detection and correction, shorter time to market and lower non-recurring engineering costs. FPGA devices can be reprogramed to fix bugs or include new features. FPGA-based data acquisition systems can process simultaneously in real-time a large number of digital signals. FPGA applications include radiation, sonar, radar and other sensor array processing, statistical signal processing, digital image processing, among others.
