BS EN 61685 is an international standard that discusses flow measurement systems.
BS EN 61685 specifies parameters for a flow Doppler test object representing a blood vessel of known diameter at a certain depth in human tissue, carrying a steady flow.
BS EN 61685 establishes a flow Doppler test object which is used to assess various aspects of the performance of Doppler diagnostic equipment.
BS EN 61685 on parameters for a flow test object is relevant to:
Flow Doppler test object is a physical model of blood flowing within a vessel that is embedded in soft tissue. The object is composed of tissue-mimicking material through which blood-mimicking material is caused to flow.
BS EN 61685 discusses definitions and a list of symbols that depict a user-friendly idea of flow measurement systems. BS EN 61685 specifies a flow Doppler test object for the acceptance testing, quality assurance testing, and clinical calibration of Doppler systems. BS EN 61685 assists users with testing the influence of the size and the depth of the blood vessel on the signal recorded by a Doppler system. BS EN 61685 also assists with testing the response of a Doppler system with a spectrum of blood velocities typical of the in vivo situation.
Overall, BS EN 61685 is useful as assists with the flow measurement systems and flow test object which can be beneficial for your business.
