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。
