Tomography equipment and tomography method based on molecular probe

The invention discloses tomography equipment based on a molecular probe. The tomography equipment comprises tomography equipment and sickbed equipment matched with the tomography equipment for use; the tomography equipment comprises a fixing frame and imaging equipment installed on the fixing frame; the fixing frame comprises a square frame body; a first through hole for containing imaging equipment is formed in the square frame body; a C-shaped plate is fixed to one surface of the square frame body; and a second through hole for installing the imaging equipment is formed in the center of thesurface of the C-shaped plate. A shaft rod is connected with the imaging equipment and fixed to the rack through a small bearing, noise and abrasion can be effectively reduced, the shaft rod can be directly connected with a motor, and driving is easy; through the adsorption effect of a suction cup on the surface of a first annular plate and the clamping and fixing effect of a clamping rod on the surface of the peripheral
