About

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.

Full description

Learning effect of MSOT measurements have been observed by previous studies. Therefore, in this study, we aim to quantify the learning effect with circulation-related parameters (Hb, HbO2, SO2) and the similarity between repeated images (structural similarity index measure, SSIM). The measurement would be repeated by 5 different investigators, two of them are professionals, defined as experience over 200 times of MSOT measurement, while the other three are trainees, who haven't performed any MSOT measurements before and each has received one different teaching method, one receiving personal teaching from a professional, one receiving video instruction and one receiving instructions written in paper form.
