Embodiment 1）
[0042] See figure 1 and figure 2 , the secondary fluorescent tomosynthesis imaging device of this embodiment includes a secondary fluorescent light source 1, a light source lifting bracket 2, a light source rotating module 3, a detection plate 4, a detection plate lifting mechanism 5, a horizontal adjustment device 6, and an initial distance setting Button set 7 and control module.
[0043]The secondary fluorescent light source adopts a secondary fluorescent light source with multiple targets, which is suitable for generating X-rays with characteristics of low power, wide angle, mono-energy or multi-energy, and high brightness. The secondary fluorescent light source with multiple targets can provide the function of dual-energy subtraction on the same device. Through dual-energy X-ray examination of the chest, and through subtraction to improve the signal-to-noise ratio and reduce the appearance of ribs, it can help identify nodules and calcifications, suggesting benign nodu...

Description
technical field [0001] The invention relates to a secondary fluorescence tomography imaging device and an imaging method thereof. Background technique [0002] In 2018, there were about 17 million new cancer cases and 9.5 million deaths worldwide. Among men, lung cancer has the highest incidence; among women, breast cancer has the highest incidence, followed by lung cancer. Most cancers are discovered when patients are symptomatic and at an advanced stage, which directly affects the success rate of cure. [0003] Radiography uses small amounts of ionizing radiation to create pictures of the internal structures of the body. X-rays are the most commonly used form of medical imaging. Since different organs and their different densities absorb X-rays that penetrate the body differently, the internal structure can be imaged by comparing the light intensity difference after X-rays pass through different parts of the human body. These images can be used to help diagnose broken ...
