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 ima

The uniform area light source emits visible light; the transparent sample is hung below the stepping motor; the transparent sample is rotated by the stepping motor; the stepping motor driver controls the rotation angle and the rotation speed of the stepping motor; the control panel controls the stepping motor driver to rotate the stepping motor; the mobile terminal is provided with Bluetooth or Wi-Fi, and is used for controlling device operation, image acquisition and reconstruction result display; and the support supports the uniform area light source, the stepping motor and the mobile terminal and is used for adjusting the height of the stepping motor and the mobile terminal. The optical projection tomography teaching system based on the smart phone is low in cost, simple in structure and convenient to operate.

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 ...
