Abstract

A magnetic resonance diagnostic apparatus is configured in such a manner that: a high-frequency transmission coil transmits a high-frequency electromagnetic wave at a magnetic resonance frequency to an examined subject; a heating coil performs a heating process by radiating a high-frequency electromagnetic wave onto the examined subject at a frequency different from the magnetic resonance frequency; based on a magnetic resonance signal, a measuring unit measures the temperature of the examined subject changing due to the high-frequency electromagnetic wave radiated by the heating coil; and a control unit exercises control so that the measuring unit measures the temperature while the heating coil is performing the heating process, by ensuring that the transmission of the high-frequency electromagnetic wave by the high-frequency transmission coil and the radiation of the high-frequency electromagnetic wave by the heating coil are performed in parallel.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2010-112454 filed on May 14, 2010 and prior Japanese Patent Application No. 2011-80817 filed on March 31, 2011, all of which The contents are incorporated by reference in this application. technical field [0003] The present embodiment relates to a magnetic resonance diagnostic apparatus that collects ecological information inside a subject by using a magnetic resonance phenomenon. Background technique [0004] In recent years, for the treatment of prostatic hyperplasia, cancer, etc., hyperthermia therapy, in which a tumor of a subject is heated, denatured and necrotic has been used. In order to perform such warming therapy more efficiently, it is necessary to know the position of the warming region in the subject and the temperature of the warming region. [0005] In order to grasp the position and temperature of the heating...
