Anatomy Dependent Optimized Image Display Orientation

- Core of the idea


The invention extends the criteria that determine the display orientation of a medical image with knowledge of the anatomy being imaged. An anatomy specific axis system is used to determine the clinically optimal orientation of images produced by medical equipment.
- What does it improve


Currently, the examination of certain anatomies produce images that appear unexpectedly mirrored for a subset of the patient population. The invention avoids this unexpected and undesired mirroring of images and therefore contributes to consistent presentation of images to medical professionals. As such it helps them in staying focused on their clinical tasks.
- What is the benefit to the customer


Consistency in how images are presented to the radiologist not only avoids confusion of what is presented in the image, but also allows for follow-up studies and multi-site trials.
- How are we going to make money with the idea?

Consistency is becoming a more and more important selling item, not only to make a general good impression of the MR system to the customer, but also because it enables follow-up studies, which will be more and more important for diagnostics and because it enables multi-site trials, which will have a positive impact on our position in the clinical research community.

A digital medical image can be produced in 8 orientations as illustrated in the following picture.

Medical professionals are used to view images in standard display orientations. A sagittal image is typically displayed with the patients Head direction at the top and the patients Anterior direction to the left. A coronal image is typically displayed with the patients Head direction at the top and the patients Left direction at the right side of the image. The choice for the preferred orientation is usually based on the angulations of the image plane in the patient coordinate system that is axis- parallel with the main axis of the medical equipment.

Suppose an MRI system is used with the intention to create coronal images of the left shoulder. A typical procedure is to first obtain a transverse survey image, and then plan the coronal plane(s) parallel to the connection line between the humerus and glenoid. For patients lying on their back, this connection line is on average roughly 30 degrees angulated with respect to the patient table. The resulting image is based on its angulations classified as "coronal" and thus displayed with the left-anterior side at the right as in the following picture:
