Abstract
A System for image processing (IPS), in particular for lung imaging. The system (IPS) comprises an interface (IN) for receiving at least a part of a 3D image volume (VL) acquired by PAT an imaging apparatus (IA1) of a lung (LG) of a subject (PAT) by exposing the subject (PAT) to a first interrogating signal. A layer definer (LD) of the system (IPS) is configured to define, in the 3D image volume, a layer object (LO) that includes a representation of a surface (S) of the lung (LG). A renderer (REN) of the system (IPS) is configured to render at least a part of the layer object (LO) in 3D at a rendering view (Vp) for visualization on a display device (DD).
Claims19
A system for image-based navigation, the system comprising:
- an input interface configured to receive i) at least a part of a three-dimensional (3D) image volume based on image data of a lung of a subject acquired pre-operatively by a first imaging modality and ii) a second image the lung in a deflated state dynamically acquired by a second imaging modality during an operation;
- and
- a processor configured to:
- define, in the 3D image volume, a layer object that includes a pattern on a surface of the lung that is representative of at least one of a lung vessel or a septum,
- identify the pattern in the second image of the lung,
- match the second image of the lung in the deflated state to the 3D image volume based on the pattern,
- render a rendering view of the 3D image volume matched to the second image, and
- display a visualization of the rendering view.
A method of image-based navigation, the method comprising:
- receiving i) at least a part of a 3D image volume of a lung of a subject based on image data acquired pre-operatively by a first imaging modality and ii) a second image of the lung in a deflated state dynamically acquired by a second imaging modality during an operation;
- defining, in the 3D image volume, a layer object that includes a pattern on the surface of the lung that is representative of a lung vessel or a septum;
- identifying the pattern in the second image;
- matching the second image of the lung in the deflated state to the 3D image volume based on the pattern;
- rendering a rendering view of the 3D image volume matched to the second image;
- and
- displaying a visualization of the rendering view.
A non-transitory computer readable medium having stored thereon instructions, which, when being executed by at least one processor, cause the at least one processor to:
- receive i) at least a part of a 3D image volume of a lung of a subject based on image data acquired pre-operatively by a first imaging modality and ii) a second image of the lung in a deflated state acquired dynamically by a second imaging modality during an operation;
- define, in the 3D image volume, a layer object that includes a pattern on the surface of the lung that is representative of at least one of a lung vessel or a septum;
- identify the pattern in the second image;
- match the second image of the lung in the deflated state to the 3D image volume based on the pattern;
- render a rendering view of the 3D image volume matched to the second image;
- and
- display a visualization of the rendering view.
