Title:
DUAL-PRECISION TEMPERATURE MEASUREMENT AND CORRECTION APPARATUS, SYSTEM AND METHOD BASED ON MAGNETIC RESONANCE AND OPTICAL FIBER TEMPERATURE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2023/274220
Kind Code:
A1
Abstract:
A dual-precision temperature correction apparatus, comprising a data collection module and a calculation module. The data collection module is used for receiving temperature data, the temperature data at least including surface temperature data and point temperature data, which are from the same ablation region. The calculation module comprises a conversion module, a determination module and a correction module, wherein the conversion module respectively converts the surface temperature data and the point temperature data into an MRI temperature monitoring point curve and a temperature measurement optical fiber temperature measurement curve; the determination module performs determination on a deviation between the MRI temperature monitoring point curve and the temperature measurement optical fiber temperature measurement curve and a mean squared error of the difference between the MRI temperature monitoring point curve and the temperature measurement optical fiber temperature measurement curve; and the correction module is used for realizing, when the determination module determines that correction is required, the correction of temperature data by amending an MRI temperature measurement equation. By means of the dual-precision temperature correction apparatus, a relationship is established between point temperature data and surface temperature data, and more precise real-time temperature monitoring is realized according to the relationship.
