Description

technical field [0001] The invention belongs to the technical field of medical imaging, and in particular relates to an optical projection tomography device, system and method based on a smart phone. Background technique [0002] At present: the basic principles of medical imaging are the necessary basic knowledge of biomedical engineering (and other related majors), but because commercial medical imaging equipment is expensive, the system structure is complex and usually has radiation, it is difficult to carry out relevant experimental teaching among students . [0003] Optical projection tomography (Optical Tomography Projection, OPT) uses the characteristics of visible light to propagate along a straight line in a weakly scattering medium. After the light beam penetrates the biological sample to obtain projection images at various angles, the three-dimensional image of the sample is obtained by using the projection image for three-dimensional reconstruction. The optical ...

Problems solved by technology

However, the general optical projection tomography system also has the disadvantages of expensive camera, complex structure and cumbersome operation, which brings difficulties to teaching and using.

[0004]Through the above analysis, the problems and defects of the existing technology are: the existing optical projection tomography system camera is expensive, the structure is complex and the operation is cumbersome

[0005]The difficulty in solving the above problems and defects is: in terms of hardware, the existing optical projection imaging system hardware structure is relatively fixed, and the cost cannot be reduced to In the state where large-scale teaching is available, its structure needs to be redesigned; in terms of software, the existing optical projection imaging system software system is object-oriented for professional researchers, and there are many parameters that need to be set to meet different experimental needs, but this is very difficult. It is not conducive to teaching use, so the software needs to be rewritten to meet the use of non-professionals in teaching

[0006]The significance of solving the above problems and defects is: the development of the industry has brought a large number of talents. However, in the education related to medical equipment, the theoretical study and There is a serious disconnect in practical application

Traditional medical imaging equipment is expensive, complex and often radiative, making it difficult to use these equipment to carry out relevant experimental teaching among students
