What this trial studies

This observational study aims to enhance the use of handheld Doppler devices in clinical practice by developing a machine-learning algorithm that assists clinicians in interpreting the audio data collected during non-invasive vascular testing. The study will gather sound files from these devices and compare the algorithm's output with established vascular testing methods. The research will focus on identifying key features in the Doppler audio for patient classification and training various classification algorithms. Ultimately, the goal is to create a smartphone app for point-of-care testing based on the findings.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals who have a clinically driven request for non-invasive vascular testing.

Not a fit: Patients who decline to participate in the study will not receive any benefit from this research.

Why it matters

Potential benefit: If successful, this approach could lead to faster and more accurate diagnoses of vascular conditions for patients.

How similar studies have performed: Other studies have shown promise in using machine learning for audio classification in medical diagnostics, indicating potential success for this approach.
