Abstract: The system and method of the invention pertains to an MR-guided breast biopsy procedure, specifically as to quickly identifying the biopsy location. More particularly, the system utilizes a diagnostic imaging modality such as magnetic resonance imaging (MRI) to locate one or more lesions in a human breast. Non-rigid registration between uncompressed screening images (where the lesion has been previously identified) and the compressed biopsy images enables easier identification of the biopsy site, hence shortening the biopsy procedure.

Abstract: The system and method of the invention pertains to an MR-guided breast biopsy procedure, specifically as to real-time tracking and navigation of a biopsy device. More particularly, the system utilizes a diagnostic imaging modality such as magnetic resonance imaging (MRI) to locate lesions in a human breast while utilizing an inertial measurement unit (IMU) to track advancement of a biopsy device in real-time. The invention simplifies the workflow of MRI-guided breast biopsies, shortens the time needed to perform the biopsy, decreases cost, and increases accuracy. This is achieved by enabling real-time visualization of the biopsy device as it advances towards the targeted lesion.

Abstract translation: 本发明的系统和方法涉及MR指导的乳腺活检程序，具体涉及活检装置的实时跟踪和导航。 更具体地，系统利用诸如磁共振成像（MRI）的诊断成像模式来定位人乳房中的病变，同时利用惯性测量单元（IMU）来实时跟踪活检装置的进展。 本发明简化了MRI指导乳腺活组织检查的工作流程，缩短了进行活组织检查所需的时间，降低了成本，提高了准确性。 这是通过使活检装置在朝向目标病变的方向上实时可视化来实现的。

Abstract: An imaging system includes an imager adapted to obtain an image of a desired region of interest of a subject and a coil positioned on the desired region of interest of the subject. The coil includes a plurality of markings disposed at a plurality of locations on the coil. The imaging system also includes a position indication device having a user interface adapted to receive input from a user indicating which of the plurality of markings corresponds to a desired scan plane of the subject.
