|Title:||APPLICATOR POSITIONING METHOD BASED ON MAGNETIC RESONANCE IMAGING, AND APPLICATOR|
An applicator positioning method based on magnetic resonance imaging (MRI), and applicator. The method comprises: inserting a positioning tube (30) into an applicator vessel (20) (101); inserting the applicator vessel (20) inserted with the positioning tube (30) into a portion to which a source is to be applied, and performing three-dimensional magnetic resonance imaging (102); determining, according to an imaging agent (31) in the positioning tube (30), an application position and an application scheme, and positioning the applicator vessel (20) at the application position (103). The method of the present invention enables the position of an applicator vessel (20) to be accurately located in an MRI image, and clearly displays morphology and pathological changes of tissues and organs in a periphery of the applicator vessel (20), thus improving the precision of a treatment.
