近年来，肿瘤热疗研究主要集中在使用高强度聚焦超声（High Intensity Focused Ultrasound，HIFU）来完成高温消融。治疗过程中利用磁共振测温技术进行无创测温。基于质子共振频率化学位移方法[1]（Proton Resonance Frequency，PRF）是磁共振测温普遍使用的方法。为保证实时和精确的要求，需要进行多通道相位合成。通过对多通道的相位差进行加权平均线性组合，有效提高了测温精度。

Recent years, tumor hyperthermia studies focused on the use of HIFU to complete the high temperature ablation. During hyperthermia,noninvasive temperature measurement is realized by using magnetic resonance temperature measurement technology. PRF is a commonly used method in magnetic resonance temperature measurement. In order to guarantee the real-time and precision requirements, we need to combine phase images from multi-channel coils. In this paper, we use weighted average linear combination to deal with phase difference of multi channel, effectively improving the accuracy of temperature.
