Nowadays, in many studies of multi-modality imaging, the ultrasound imaging in high magnetic environment are expected applying to not only RFA but also the diagnostic of breast cancer. We aim at developing the multi-modality imaging system with the probe enabled to use in high magnetic environment. We studied the positioning accuracy between them after estimating the probe position and B-mode image from MR image by no magnetic probe with MR marker. We made agar phantom having a cylindrical acryl and took MR image. We estimated B-mode image from MR image and fused. We evaluated fused image by measuring length between the bottom of phantom and cylinder in each image. In result, the error length was from 2.2 mm to 3.4 mm and the error causing is that resolution of B-mode image to slice direction is about 8 mm. In the future, we intend to improve positon accuracy by acoustic lens.
