The invention realizes the magnetic fluid therapy with the characteristics of image-guided therapy, precise thermal dose setting, non-invasive real-time temperature monitoring and precise positioning.

Description

technical field [0001] The invention belongs to the technical field of magnetic nanoparticle imaging and hyperthermia fusion, and in particular relates to a field-free line scanning imaging and field-free point positioning hyperthermia fusion device and method based on magnetic particles. Background technique [0002] Magnetic fluid hyperthermia utilizes a suspension of magnetic nanoparticles, administered systemically or locally, combined with an externally applied alternating magnetic field, to ablate target tissue by generating heat through a process called induction. Heat generated at 37°C above mammalian body temperature induces apoptosis and / or enhances the sensitivity of target tissues to other therapies, such as radiotherapy and chemotherapy. While most hyperthermia techniques currently in development are aimed at cancer treatment, hyperthermia is also used to treat restenosis, remove plaque, ablate nerves, and reduce pain by increasing local blood flow. While magne...
