Abstract: A temperature measuring method and apparatus based on creatine chemical exchange saturation transfer (CEST) imaging. The method comprises the following steps: (1) performing creatine CEST imaging on a creatine phantom, and analyzing a chemical shift of creatine relative to water in the creatine phantom; (2) fitting a mathematical relation between the chemical shift of the creatine relative to water and the temperature; and (3) performing CEST imaging on creatine in a sample, and calculating the temperature according to the mathematical relation, fitted in step (2), between the chemical shift of the creatine relative to water and the temperature. In the temperature measuring method, the creatine is taken as an endogenous reference, and highly-spatial-resolution, highly-sensitive, and non-invasive absolute temperature measurement can be implemented by means of temperature dependence of a CEST effect of Cr and water.

Abstract: Disclosed are a texture synthesis method and a device using the same. The texture synthesis method adopts a source labeled diagram and a target labeled diagram in combination to guide the texture synthesis process, so that the texture synthesis is in a controlled state, thus effectively improving the accuracy and efficiency of the computer in processing complex texture information such as textures composed of multiple materials or textures involving non-uniform gradients. Meanwhile, determination of the accuracy of the texture features of the labeled diagram is introduced to the process of producing the labeled diagram, and the labeled diagram with low accuracy is re-abstracted and -segmented so that the classification of the texture features would be more accurate. This interactive iterative method improves the accuracy of the labeled diagram generation process. The device using this method also provides the same technical effects.
