Abstract

The invention belongs to the technical field of magnetic nanoparticle imaging and thermal therapy fusion, and particularly relates to a field-free line scanning imaging and field-free point positioning thermal therapy fusion device and method based on magnetic particles. The invention aims to solve the problem that the existing magnetofluid treatment means lacks image guided treatment, accurate thermal dose setting, non-invasive real-time temperature monitoring and accurate positioning. The device comprises a magnet group, an induction coil, a living body bed, a control device, a display device, an image processing device and a cooling system, the magnet group comprises two groups of long bent magnet pairs and a cylindrical magnet; two ends of a long bent magnet in the long bent magnet pair are semi-circular rings, and the semi-circular rings are connected by two sections of arcs constructed at set curvature; and the control device is configured to perform scanning imaging on the target living body object and perform thermal therapy on the set part. According to the invention, magnetofluid treatment with the characteristics of image-guided treatment, accurate thermal dose setting, non-invasive real-time temperature monitoring, accurate positioning and the like is realized.

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...
