The invention discloses a double-panel imaging device based on continuous crystals. The double-panel imaging device comprises two detection modules. The detection modules comprise the continuous crystals, photovoltaic conversion parts and array read-out electronics systems, wherein the photovoltaic conversion parts are next to the continuous crystals, and the array read-out electronics systems are connected with the photovoltaic conversion parts. According to the double-panel imaging device, the double-panel structure is adopted, the continuous crystals are adopted in the detection modules, the depth effect is effectively avoided, no detection dead zones exist, detection efficiency and detection sensitivity can be improved, and then imaging accuracy and reliability are improved.
Description
technical field [0001] The invention relates to the field of molecular imaging, in particular to a double-plate imaging device. Background technique [0002] Nuclear medicine imaging technology can reflect the metabolic characteristics of tissues and organs in the human body through images. Through the analysis of these metabolic characteristics, early diagnosis can be made for a series of major diseases such as tumors, cardiovascular diseases, and nervous system diseases. It is an important aspect of medical imaging. part, has broad prospects. [0003] In the diagnosis of tumor diseases, diagnostic techniques and methods based on X-rays or ultrasound have played an important role in the diagnosis, and have significantly improved the diagnostic and therapeutic effects. However, these methods are all based on imaging diagnosis of structural lesions, and are less effective in terms of cancer type, staging, and qualitative, and the image quality of soft tissue imaging cannot m...
