    A novel blood vessel diameter gauge offers non-contact measurement of vessels (1-14 mm) with high resolution (28 micrometers) and stability. This innovative device utilizes a new photoelectric transducer for precise, real-time vascular assessment.

    Area of Science:

    • Biomedical Engineering
    • Medical Imaging
    • Optical Transducers

    Background:

    • Accurate measurement of blood vessel diameter is crucial for diagnosing and monitoring various cardiovascular conditions.
    • Existing methods may be invasive, lack precision, or have limited applicability.
    • Advancements in photoelectric transducer technology offer new possibilities for non-invasive diagnostic tools.

    Purpose of the Study:

    • To design and construct a novel, high-resolution, contact-free blood vessel diameter gauge.
    • To evaluate the performance characteristics of the developed gauge for potential clinical applications.
    • To demonstrate the feasibility of the device through preliminary in vitro and in vivo experiments.

    Main Methods:

    • Development of a blood vessel diameter gauge employing a high-resolution, stable image sensor as a photoelectric transducer.

  • Integration of a cuff-type probe for ease of use and a cold lightguide via optical fibers.
  • Characterization of the gauge's resolving power, frequency response, and measurement range (1-14 mm).

    • Main Results:

    • The gauge enables contact-free measurement of blood vessel diameters ranging from 1 to 14 mm.
    • The device achieves a principal resolving power of 28 micrometers.
    • A flat frequency response up to 100 Hz was confirmed, suitable for dynamic measurements.
    • Preliminary in vitro and in vivo experiments demonstrated the gauge's effectiveness.

    Conclusions:

    • The developed blood vessel diameter gauge is a promising non-invasive tool for vascular assessment.
    • Its high resolution, contact-free capability, and ease of use offer significant advantages over existing methods.
    • Further research and clinical validation are warranted to establish its full diagnostic potential.
