The medphot simulator is an indispensable bridge between theory and practice and provides a practical and manageable platform for assessing instrument performance. These simulation systems, which are sophisticated and detail-oriented, provide a real and replicable testing environment by perfect replicating the optical properties of real biological tissues。
The package contains solid optical models of cylinders or squares with different optical characteristics。
The medphot programme contains five key standards (tests) to ensure reliability and accuracy of measurements: accuracy, linearity, noise, stability and repetitivity。
1. Accuracy: the accuracy test assesses the degree to which measured values match real values. By comparing measurements with established reference standards, researchers can quantify the level of consistency between the two. For example, in brain oxidation studies, the oxygen saturation measured near the infrared spectrum (nirs) can be compared with intrusive measurements carried out in the catheters directly placed in the blood vessels to assess the accuracy of the nirs system。
Linearity: the ability of the linearity assessment system to maintain consistency of measurements at different concentrations. Using samples of target molecules at different concentrations (e. G. Oxyglobin and deoxyglobin), researchers can assess whether the measurements present linear responses. This is essential to ensure that equipment accurately reflects changes in organizational characteristics。
3. Noise: noise detection is used to detect background disturbances or random fluctuations in receiving signals. By measuring signals without any samples, researchers can determine the level of the system's inherent noise. Lower noise levels can increase the system's sensitivity to minor changes in organizational characteristics, thus achieving more reliable measurements。
4. Stability: stability of the stability test evaluation system over time. By repeatedly measuring stable samples over a longer period of time, researchers can identify any drift or change in systemic energy. This assessment ensures that the near-infrared spectroscopy remains accurate and consistent in long experimental or clinical applications。
Repetitivability: repeatability is measured by the consistency of the results when near-infrared spectral measurements are repeated under similar conditions. This can be achieved through multiple measurements of the same sample or different samples with the same characteristics. High repetitivity ensures reliable replication of measurements by different researchers in various settings。
