Description

technical field

[0001] The invention relates to the field of tumor treatment, in particular to a HIFU tumor ablation system. Background technique

[0002] MRI (Magnetic Resonance Imaging) system is an imaging technique that reconstructs images by collecting signals generated by magnetic resonance phenomena. The atomic nuclei (including cardinal protons or neutrons, generally referring to hydrogen protons) in human tissue are magnetized in a strong magnetic field. After the gradient field gives spatial orientation, radio frequency pulses excite hydrogen protons with a specific precession frequency. The energy released during the hesitation process is the magnetic resonance signal. The computer collects the magnetic resonance signals, converts them into black and white grayscale according to the signal intensity, forms two-dimensional or three-dimensional forms according to the position, and finally forms a magnetic resonance image (MRI). It has the advantages of no radiatio...
