Aspects of this disclosure are generally related to radiological imaging, and more particularly to blood vessel appearance using extended reality headsets.
One of the challenges that physicians face when viewing a volume with an augmented reality, virtual reality or mixed reality headset is visualization of blood flow.
All examples, aspects and features mentioned in this document can be combined in any technically possible way.
In accordance with some implementations a method of denoting blood flow within a 3D volume on a head display unit (HDU), comprises: generating a 3D volumetric dataset containing at least one blood vessel; generating at least one pointer; determining the direction of blood flow; modifying the 3D volumetric dataset by placing the at least one pointer in proximity to the at least one blood vessel in a direction aligned with a direction of blood flow; displaying, in said HDU, a left eye image based on said modified 3D volumetric dataset and a right eye image based on said modified 3D volumetric dataset, wherein said left eye image and said right eye image are alternate three-dimensional images; and displaying, in said HDU, the at least one pointer advancing in the direction of blood flow. In some implementations placing the at least one pointer in proximity to the at least one blood vessel comprises placing a 2D arrow. In some implementations placing the at least one pointer in proximity to the at least one blood vessel comprises placing a 3D arrow. Some implementations comprise displaying, in said HDU, the pointer with changing color. Some implementations comprise displaying, in said HDU, the pointer advancing in the direction of blood flow faster in arteries than veins.
Some aspects, features and implementations described herein may include machines such as computers, electronic components, radiological components, optical components, and processes such as computer-implemented steps. It will be apparent to those of ordinary skill in the art that the computer-implemented steps may be stored as computer-executable instructions on a non-transitory computer-readable medium. Furthermore, it will be understood by those of ordinary skill in the art that the computer-executable instructions may be executed on a variety of tangible processor devices. For ease of exposition, not every step, device or component that may be part of a computer or data storage system is described herein. Those of ordinary skill in the art will recognize such steps, devices and components in view of the teachings of the present disclosure and the knowledge generally available to those of ordinary skill in the art. The corresponding machines and processes are therefore enabled and within the scope of the disclosure.
Several features, aspects, embodiments, and implementations have been described. Nevertheless, it will be understood that a wide variety of modifications and combinations may be made without departing from the scope of the inventive concepts described herein. Accordingly, those modifications and combinations are within the scope of the following claims.
This application is a Continuation of U.S. patent application Ser. No. 16/506,073, filed Jul. 9, 2019, which is a Continuation of U.S. patent application Ser.
