Method and system for correcting ultrasonic focusing focus position error of nuclear magnetic resonance monitoring image |
| abstract |
The invention provides a method for determining the focus position of ultrasonic focus in a thermographic image. The method includes obtaining a nuclear magnetic resonance thermographic image of ultrasound-heated tissue and using chemical shift correction and k-space displacement correction to map the nuclear magnetic resonance thermographic image The wrong focus position correction coincides with the actual focus position of the focused ultrasound, where the chemical shift correction is to correct the change in the resonance frequency of the hydrogen nucleus due to the environmental differences of the water molecules in the nuclear magnetic resonance thermal image, which leads to the first space of the ultrasound focus focus Error, and the k-space correction is to correct the temperature error caused by the change of the main magnetic field in space during nuclear magnetic resonance thermal imaging, which in turn leads to the second spatial error of the focal point. |
