The embodiment of the present invention relates to the technical field of fluorescence imaging, in particular to a medical fluorescence imaging data acquisition system and an acquisition method thereof.
Fluorescence is a common luminescence phenomenon in nature. The fluorescence is generated by interaction of photons with molecules, and the interaction process can be described by a Jablonslc molecular energy diagram as follows: most molecules are in the lowest vibration energy level So of a ground state in a normal state, the electrons around atomic nuclei are transited from the ground state energy level So to an excited state (a first excited state or a second excited state) with relatively high energy after being excited by energy (light energy, electric energy, chemical energy and the like), and the electrons in the excited state are in a high-energy state and unstable and may return to the ground state after releasing the energy through two ways, wherein one way is a radiative transition (including fluorescence and phosphorescence processes) releasing the energy in a form of photons, and the other way is a non-radiative transition releasing the energy in a form of heat energy and the like. Generally, after being excited and transiting from the ground state So to the excited state Si, the electrons outsides the atomic nuclei may rapidly fall at the lowest vibration energy level in a mode of non-radiative transition and then return to the ground state from the lowest vibration energy level to release the energy in the form of photon radiation, and emergent light with the property is called fluorescence.
