NCT05773547

Brief Summary

The goal of this observational study is to investigate the learning effect in the measurement of micro-circulation in healthy participants using MSOT. The main question it aims to answer are: If there if a learning effect in MSOT measurement. How long does it takes for the trainees to reach the professional level. Is there a difference between different learning methods? Participants will have to lie on the examination bed while investigator making measurements 7 times in a row on one single location.

Outcome Measures

Primary Outcomes (2)

  • Learning curve in MSOT measurements.

    If the quality of MSOT measurements improved with practices.

    5 days

  • Different learning curve between professionals and trainees.

    Observe the possible difference between the learning curves in professionals and trainees.

    5 days

Secondary Outcomes (1)

  • Different learning curve in three different teaching methods

    5 days

Study Arms (4)

Professional

Two investigators who have performed over 200 MSOT measurements.
