Design of mri coils for mr imaging guided diagnosis and hyperthermia therapy

Abstract

Insight into human diseases is significantly assisted by animal phantom newlinesimulation modelling, which has several applications in medicine, from newlinedisease diagnosis to treatment. Medical imaging techniques like Magnetic newlineResonance Imaging (MRI) can be used to reconstruct anatomical structures newlinefrom computational models. This approach is used in order to distinguish newlinebetween normal and malignant tissues during diagnosis. Magnetic resonance newlineimaging (MRI) is the most popular non-invasive approach for predicting newlinetemperature during hyperthermia treatment. The MRI system relies heavily on newlinethe microstrip patch antenna. It is used not only to detect the disease but also newlineto treat cancerous tissues by induced heat. This causes a hyperthermic effect. newlineThe specific absorption rate (SAR) for a dual-use bow-tie antenna in MR newlineimaging and heating has been presented. newlineThe proposed MRI coil delivers both diagnostic imaging and healing newlinethe tumor tissues using hyperthermia. The 7-Tesla MRI resonant frequency newlinecreates an impedance bandwidth of 500 MHz. As a result, the proposed MRI newlinecan be used to verify the proposed simulated human hand and small animals newlineof rat phantom models. Furthermore, these coils are set up on an xy-plane, newlinewhere the magnetic flux lines passing along the Bx and By axes are least newlineintense along the z-axis. These problems can be fixed by adapting proper newlinegeometric configuration and geo-coordinates of the antenna. By generating newlinerobust magnetic and electric fields, this will aid in raising the induced newlinetemperature on the phantom model. Thus, these experimental platforms can newlineprovide both imaging based on diagnostic tools and induced heating for newlinehyperthermia therapy during the diagnosis trials. newline
