Methods and Systems for Identifying Anatomical Landmarks in Image Data

摘要

Systems, devices, and methods are described for locating and identifying anatomical landmarks, such as ligament attachment points, in image data. These systems, devices, and methods may provide an oblique plane that contains an anatomical landmark such as a ligament attachment point to the tibia. For example, the position at which the anterior cruciate ligament (ACL), medial collateral ligament (MCL) posterior cruciate ligament (PCL), or patellar tendon attaches to the tibia may be identified. The systems, devices, and methods allow for tracing of an anatomical landmark to generate a 3-D marking on a 3-D surface model of a patient's bone. The attachment points may be useful landmarks for patient-matched instrumentation.

主权项

1. A method for locating anatomical landmarks in image data, comprising:
receiving, at a processor, image data representative of a patient's joint; identifying an oblique plane intersecting a soft tissue represented in the image data and normal to a longitudinal axis of the soft tissue; identifying, with the processor, a set of planes comprising the oblique plane and at least one other plane parallel or orthogonal to the oblique plane; generating, with the processor, a set of reformatted images, from the image data, sampled along the set of planes; tracing a feature of the soft tissue in the set of reformatted images; and generating, with the processor, a 3-D marking representing the traced feature on a 3-D model.
