Abstract
An apparatus configured to generate for display a plurality of vasculature (115) views (170a-c) alongside a live fluoroscopy image (190a). The views are selected in such a way that they allow visualizing the 3D structure of the vasculature segment in which the device (117) is currently navigating. The view is best relative to one or a weighted average of a plurality of goodness of view standards. As the device progresses and new fluoroscopy images (190b-c) are acquired, the views (170i-k) are updated accordingly.
Claims16
An apparatus (200) for aiding in navigating a device (117) in a network (115) of tubular structures, comprising:
- an input unit (205) configured to receive a current reference projection image (190a) acquired at a first projection direction whilst the device is residing in the network of tubular structures, the projection image showing, when displayed, a footprint of the device;
- a processing unit (201) configured to use a current in-image position of the footprint and a model of the network to retrieve, without using acquired 3D image data of the network, a supplementary projection image (170a, 170i) from a sequence (170a-c) of previously acquired 2D projection images, the so retrieved supplementary image showing, when displayed, at least a partial footprint (115a) of the network (115), the so retrieved supplementary image affording a view along a second projection direction on the network at a section of interest where the device currently resides;
- a graphics display generator (270) configured to generate for display on a screen a graphics panel (280) including the current projection image and the supplementary projection image, the apparatus configured to update the graphics panel upon receipt of a new projection image (190b) at the input unit (205), the updated panel then including the new projection image (190b) and a newly retrieved supplementary projection image (170j-k).
A method of aiding in navigating a device in a network of tubular structures, the method comprising:
- receiving (S305) a current projection image acquired at a first projection direction whilst the device is residing in the network of tubular structures, the projection image showing, when displayed, a footprint of the device;
- using a current in-image position of the footprint and a model of the network to retrieve (S310), without using acquired 3D image data of the network, a supplementary projection image from a sequence of previously acquired 2D projection images, the so retrieved supplementary image showing, when displayed, at least a partial footprint of the network, the so retrieved supplementary image affording a view along a second projection direction on the network at the section of interest where the device currently resides;
- generating (S320) for display on a screen a graphics panel including the current projection image and the supplementary projection image, the apparatus configured to update the graphics panel upon receipt of a new projection image at the input unit, the updated panel then including the new projection image and a newly retrieved supplementary projection image.
