- TTFM signal acquisition system with USB interface E. Carrillo Barroso A. Jiménez Cañas E. Moreno Hernández D. Torres Guzmán Física, Astronomía y Matemáticas coronary implants Transit time method blood flow measurements To measure blood volume flow, a method known as Transit Time Flow Measurement (TTFM) is used, regarded as one of the most accurate. It is currently employed as an essential complement in the verification of coronary implants (by pass) during the surgery process. Accordingly, this paper presents a technical solution to measure the blood flow, which consists of an analog card, a USB interface card and a personal computer. The USB interface receives signals from the analog card; it converts them into digital signals and finally, are sent to the computer via USB port. By means of LabView software, the data is processed and the results are exposed in a display. The signals are displayed and the value of blood volume flow is shown, which are of vital importance during coronary bypass surgery. 2013 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030970016 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
