Magnetic particle imaging and thermal therapy fusion device based on field-line-free inertial scanning

Abstract

The invention belongs to the technical field of magnetic particle imaging and thermal therapy fusion, and particularly relates to a magnetic particle imaging and thermal therapy fusion device and method based on field-line-free inertial scanning. The objective of the invention is to solve the problems that an existing magnetofluid treatment means lacks image guided treatment, accurate thermal dose setting, non-invasive real-time temperature monitoring and accurate positioning, and classic field-line-free scanning MPI equipment is too high in complexity in design and implementation of structure and control. 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 a group of long bent magnet pairs and a cylindrical magnet; 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; and meanwhile, the device is simple in structure and control.

Description

technical field [0001] The invention belongs to the technical field of magnetic particle imaging and hyperthermia fusion, and in particular relates to a magnetic particle imaging and hyperthermia fusion device and method based on inertial scanning without field lines. 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 magnetic fluid hyperthermi...
