Abstract
Methods and systems are provided for displaying a 3D ultrasound image volume in a desired view orientation. A 3D ultrasound image can be acquired of an anatomical feature in a patient. The actual orientation of the anatomical feature can be determined in space. The 3D ultrasound image including the anatomical feature can be displayed such that the anatomical feature is positioned in a selected orientation that is different than the actual orientation, and in relation to a lighting model for generating lighting and shadowing on the anatomical feature.
Claims17
A method for displaying a 3D ultrasound image in a desired view orientation, the method comprising:
- acquiring 3D ultrasound image data comprising a view of an anatomical feature in a patient, wherein the anatomical feature comprises at least a portion of a heart;
- determining an actual orientation of the anatomical feature in relation to a transducer probe, wherein determining the actual orientation comprises applying a heart model to define a surface orientation of the anatomical feature, identifying anatomical landmarks in the anatomical feature, or a combination thereof;
- and
- displaying, at the same time and based on the acquired image data comprising the view of the anatomical feature, a plurality of real-time volume renderings of the 3D ultrasound image data, each real-time volume rendering being selectable by a user for displaying an enhanced view, wherein each of the plurality of real-time volume renderings comprises the anatomical feature as perceived from a different orientation than the acquired image data comprising the view of the anatomical feature and wherein each of the plurality of volume renderings is in spatial relation to a different lighting model such that lighting and shadowing regions on the anatomical feature are displayed.
A system for displaying a 3D ultrasound image volume in a desired view orientation, the system comprising
- a transducer probe configured to acquire 3D ultrasound image data comprising an anatomical feature in a patient, wherein the anatomical feature comprises at least a portion of a heart;
- a processor to determine an actual orientation of the anatomical feature in space, wherein determining the actual orientation comprises applying a heart model to define a surface orientation of the anatomical feature, identifying anatomical landmarks in the anatomical feature, or a combination thereof;
- and
- a display configured to display, at the same time and based on the acquired image data comprising the view of the anatomical feature, a plurality of real-time volume renderings of the 3D ultrasound image data, each real-time volume rendering being selectable by a user for displaying an enhanced view, wherein each of the plurality of real-time volume renderings comprises the anatomical feature as perceived from a different orientation than the acquired image data comprising the view of the anatomical feature and wherein each of the plurality of real-time volume renderings is in spatial relation to a different lighting model such that lighting and shadowing regions on the anatomical feature are displayed.
