摘要： PROBLEM TO BE SOLVED: To provide an RF coil performing blocking effectively and a magnetic resonance imaging instrument equipped with such an RF coil. SOLUTION: The RF coil comprises a coil loop having a capacitor 302 in which input circuits of low input impedance amplifiers 306 are connected in parallel through a inductor 308. The resonance frequencies of the input circuit of the low input impedance amplifier and a closed circuit consisting of an inductor and a capacitor are shifted to a region lower than the resonance frequency of the coil group.

摘要： PROBLEM TO BE SOLVED: To realize a radiation detector which is suitable for use in doing a high spatial resolution shoot using two or more detection element arrays. SOLUTION: A radiation detector detects detection element arrays 250' and 270' by a detector array 24 which are arranged in the thickness direction of the radiation beam. Each of the radiation detection elements has the entrance plane of the same parallelogram mutually. The entrance plane of a parallelogram 130 is formed by the radiation detection elements which abut in the thickness direction of the radiation beam with each other as a whole. This composite parallelogram 130 has a diagonal line perpendicular to the upper hem and the lower hem in the arrangement direction of the detection element arrays 250' and 270' and consists of the combination of two congruent right triangles which border this diagonal line. In two or more detection element arrays in the composite parallelogram, the radiation about the same slice is detected. COPYRIGHT: (C)2008,JPO&INPIT
