How to calculate required concentration of absorbing agent

[Vincent7643]

Hi All,

I am designing an optical solid phantom to represent tissue optical properties (scattering and absorption coefficients).

I know what should be the optical properties of tissue but I don't how much absorbing agent should I add to the mixture so that the phantom exhibit my desired optical properties?

Thanks very much in advance.

Hi Vincent,

Thank you for sharing your project with us. Designing an optical solid phantom can be a challenging task, but it is also an important one in the field of tissue optics research.

To determine the amount of absorbing agent you should add to your mixture, you will need to consider the specific properties of the absorbing agent, such as its absorption coefficient and concentration. These properties will affect the overall optical properties of your phantom.

One approach you could take is to use a mathematical model, such as the Kubelka-Munk theory, to calculate the absorption coefficient of your mixture based on the properties of the individual components. This can help you determine the optimal concentration of the absorbing agent to achieve your desired optical properties.

Another option is to conduct experiments using different concentrations of the absorbing agent and measure the resulting optical properties. This can help you fine-tune the amount of absorbing agent needed for your specific needs.

I would also recommend consulting with colleagues or experts in the field who have experience in designing optical phantoms. They may have valuable insights and suggestions to help you in your project.

Best of luck with your research!
