Embodiment Construction

[0022] The following disclosure describes the invention in terms of several embodiments relating to methods, systems, and devices related to automatic alignment of anatomy within an image volume using a combination of a landmark engine and a steering engine. Briefly, a landmark engine is used to first perform a rough localization of the center of the anatomical object. Then, the steering engine is used to detect the two main axes of the elbow. Using the detected axes, anatomical objects are registered to canonical space before using a landmark engine to perform refined detection of relevant anatomical features in the aligned images. Once all relevant landmarks are detected, they can be used to compute several frames of reference to scan the anatomical object in the desired orientation. The ability to precisely and automatically align anatomical objects may be useful for population-based object studies, or for rapid planning of MR scans, independent of the patient's elbow post...

Abstract

The application relates to a combined steering engine and landmarking engine for elbow auto alignment. A method to automatically align magnetic resonance (MR) scans for diagnostic scan planning includes acquiring a three-dimensional (3D) localizer image of an anatomical object. One or more initial landmarks are identified in the 3D localizer image using a landmarking engine. One or more main axesassociated with the anatomical object are identified based on the one or more initial landmarks. The 3D localizer image is registered to a canonical space based on the main axes associated to yield aregistered 3D localizer image. The landmarking engine is applied to the registered 3D localizer image to yield one or more updated landmarks. A plurality of reference points for performing a MR scan are computed based on the one or more updated landmarks.

Description

[0001] This application claims the benefit of US Provisional Application Serial No. 62 / 533,874, filed July 18, 2017, which is incorporated herein by reference in its entirety. technical field [0002] The present invention generally relates to methods, systems and apparatus for combining a steering engine and landmarks for medical resonance imaging (MRI) applications scanning the elbow of a subject. For example, the techniques discussed herein can be applied to precisely and automatically align the elbow to facilitate population-based studies of elbow anatomy within fast and automatically planned MRI exams or further image processing steps. Background technique [0003] MRI is a non-invasive diagnostic technique that produces images of the body's soft tissues and bones based on the magnetic resonance of atoms within the body. Typical applications of MRI include imaging the brain, abdomen, and spine; however, in general, any anatomical structure that includes soft tissue can ...
