Doppler Ultrasonic System for Flow Measurement in Patients with Diabetic Foot Using Reconfigurable Logic and Wishbone Architecture
2016
The first results in the design of a pulsed Doppler ultrasound system are presented, which aims to detect alterations of diabetic foot cataloged as ”high risk”, associated with the processes that lead to occlusion of blood vessels. Therefore, measurement of blood flow gives the level of damage in the affected area and the state of the blood vessels, constituting a noninvasive diagnostic test. The system was designed from the classical conceptions of Pulsed Doppler systems and also, incorporates advanced digital design techniques based on hybrid hardware-software implementations (FPGA) on reconfigurable platforms. The analog system architecture is shown and finally, its most outstanding features and the expected results of the design are exposed.
