document: Hardware and software platform for real-time processing and visualization of echographic radiofrequency signals In this paper the architecture of a hardware and software platform , for ultrasonic investigation is presented . The platform , used in conjunction with an analog front-end hardware for driving the ultrasonic transducers of any commercial echograph , having the radiofrequency echo signal access , make it possible to dispose of a powerful echographic system for experimenting any processing technique , also in a clinical environment in which real-time operation mode is an essential prerequisite . The platform transforms any echograph into a test-system for evaluating the diagnostic effectiveness of new investigation techniques . A particular user interface was designed in order to allow a real-time and simultaneous visualization of the results produced in the different stages of the chosen processing procedure . This is aimed at obtaining a better optimization of the processing algorithm . The most important platform aspect , which also constitutes the basic differentiation with respect to similar systems , is the direct processing of the radiofrequency echo signal , which is essential for a complete analysis of the particular ultrasound-media interaction phenomenon . The platform completely integrates the architecture of a personal computer -LRB- PC -RRB- giving rise to several benefits , such as the quick technological evolution in the PC field and an extreme degree of programmability for different applications . The PC also constitutes the user interface , as a flexible and intuitive visualization support , and performs some software signal processing , by custom algorithms and commercial libraries . The realized close synergy between hardware and software allows the acquisition and real-time processing of the echographic radiofrequency -LRB- RF -RRB- signal with fast data representation
