| Abstract | Arteriosclerosis reduces the lumen of blood vessels leading to ischaemia. Vascular surgeries implant grafts to bypass the lesions, allowing the perfusion of the distal tissue. The postoperative follow-up of the vascular reconstruction is highly desirable to detect technical errors. These errors can cause member amputation or even, the patient death. These outcomes can be avoided by the premature diagnosis of graft failures that allows a second intervention to repair it. Researchers have investigated quantitative parameters obtained from blood flow waveforms to assess vascular reconstruction surgeries. These waveforms are sampled by ultrasound Doppler. Aiming to build a versatile system to research these parameters, this work presents software developed to acquire and process Doppler signals. A Continuous Wave Ultrasound Doppler board generates the signals to be processed. The software computes the sonogram, maximum and mean velocity curves that are shown on the PC screen in real time. |
