Abstract

The invention provides a multi-nuclide multi-frequency resonance synchronous imaging system which is used for detecting the tumor ion dynamic balance, the energy metabolism, the molecular target change and the tumor microenvironment change. The system can simultaneously transmit radio frequency pulse signals corresponding to four nuclides of 1H, 23Na, 31P and 19F and synchronously receive the nuclear magnetic resonance load signals of the four nuclides. The multi-nuclide multi-frequency resonance synchronous imaging system comprises a signal excitation system, a multi-nuclide multi-frequency signal excitation and acquisition system, a magnetization system and an imaging system. The multi-nuclide multi-frequency signal excitation and acquisition system comprises four nuclide channel modules of 1H, 23Na, 31P and 19F, and each nuclide channel module comprises a signal excitation power amplifier submodule and a signal acquisition submodule. The magnetization system comprises magnets and radio frequency transmitting coils. The imaging system comprises a signal preamplifier, a signal acquisition command module, an image reconstruction module, an image post-processing and display module and an image database.

Description

technical field

[0001] The invention relates to an imaging system, in particular to a multi-nuclide multi-frequency resonance synchronous imaging system, which is used to detect the dynamic balance of tumor ions, energy metabolism, changes in molecular targets and changes in tumor microenvironment. Background technique

[0002] Malignant tumors seriously endanger human health and are a major problem in the medical field. According to the latest statistics from the 2015 China Cancer Registry Annual Report: In the past 10 years, the incidence of malignant tumors in my country has been increasing year by year. As of 2011, the annual incidence of malignant tumors has reached 3.37 million. A Cancer Journal for Clinicians (CA), the world's authoritative journal of oncology, predicts that this number will reach 4.3 million in 2015. Due to the unclear pathogenesis and lack of targeted early diagnosis, the average 5-year survival rate of tumors is only 4.3 million. 36.9%, while lung...
