Apparatus and method for localizing bragg peak of hadron beam traversing target tissue by magnetic resonance imaging

The present invention concerns a method and medical apparatus for visualizing a hadron beam traversing an organic body, the method comprising capturing a magnetic resonance image, wherein a volume ofirradiated excitable atoms A1, surrounding a hadron beam and whose magnetic susceptibility has been modified by the hadron beam is captured as a hyposignal. A hyposignal is obtained by saturating thespins of the irradiated excitable atoms A1, before capturing a MR image based on the excitation of the excitable atoms A0 which are not affected by the hadron beam. 本发明涉及种用于使横穿有机体的强子射束可视化的方法和医疗设备，所述方法包括捕获磁共振图像，其中，围绕着强子射束并且磁化率已被所述强子射束修改的被照射可激发原子A1的体积作为亚信号被捕获。在基于不受强子射束影响的可激发原子A0的激发来捕获MR图像之前，通过使被照射可激发原子A1的自旋饱和来获得亚信号。
