Abstract

The invention relates to a 3D printing device and method of biological tissue optical simulation. By mainly employing the 3D printing principle and based on a multi-channel melting and depositing nozzle, a heterogeneous optical simulation capable of accurately simulating the optical characteristics of a biological tissue can be rapidly prepared and the calibration of various optical medical image instruments can be met.

Description

technical field [0001] The invention relates to the field of biomedical engineering, and more specifically, belongs to the production of phantom models simulating the optical properties of biological tissues by using the principle and method of three-dimensional printing. The invention realizes the preparation of the optical phantom of the three-dimensional heterogeneous biological tissue, and has great significance for the optical measurement calibration of the biological tissue and the standardization of the optical medical image. Background technique [0002] Biological tissue optical phantom is a bionic model that imitates the optical characteristics (absorption characteristics, scattering characteristics) of biological tissues. It is mainly used for calibration and calibration of biological optical imaging instruments and simulation experiments instead of living organisms. , The scattering material is prepared in a certain proportion according to the optical properties....
