Tomographic imaging system and connection assembly thereof

A tomographic imaging system, comprising:

• a frame body;
• a base slidably disposed on the frame body and comprising a rotor;
• a light generator disposed on the frame body;
• a connection assembly, comprising:
• a carrying platform connected to the base and comprising a rotatable component, a first circuit board and a connection component, wherein the rotatable component is connected to the rotor of the base and configured to be driven to rotate by the rotor, wherein the connection component is passed through an opening of the rotatable component and connected to the first circuit board and the base respectively, and the first circuit board comprises a plurality of first conductive terminals;
• and
• a holding bed comprising a holding component, a bearing and a second circuit board, wherein the holding component comprises an engaging portion and a space, the second circuit board is accommodated within the space and connected to the holding component through the bearing, and the second circuit board comprises a plurality of second conductive terminals, wherein the engaging portion is detachably connected to the rotatable component so that the first conductive terminals and the second conductive terminals are electrically connected to each other to generate an identification signal;
• a detector slidably disposed on the frame body;
• and
• a controller disposed on the frame body and configured to receive the identification signal and adjust positions of the carrying platform, the holding bed and the detector relative to the light generator according to the identification signal respectively, wherein the rotor is controlled by the controller to rotate an object carried on the holding component of the holding bed through the rotatable component, whereby the light generator irradiates the object to perform a tomographic scan.
