Displaying a device within an endoluminal image stack

摘要

Apparatus and methods are described including, while an endoluminal data-acquisition device is being moved through a subject's lumen, acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device. It is determined that respective endoluminal data points correspond to respective locations along the lumen. A display is driven to display at least some of the plurality of endoluminal data points in a stack. While a second endoluminal device is inside the lumen, a current location of at least a portion of the second endoluminal device with respect to the lumen is determined. In response thereto, an image of the second endoluminal device is displayed within the stack, at a location within the stack corresponding to the current location of the second endoluminal device. Other applications are also described.

1. Apparatus comprising:
an endoluminal data-acquisition device configured to acquire a plurality of endoluminal data points while moving through a lumen of a subject's body; a second endoluminal device configured to be moved through the lumen; a display; and at least one processor configured to:
determine that respective endoluminal data points correspond to respective locations along the lumen,generate a stack of the endoluminal data points, in which the endoluminal data points are positioned at locations corresponding to relative locations within the lumen at which the endoluminal data points were acquired,while the second endoluminal device is inside the lumen, and while the endoluminal data-acquisition device is in a retrieved state with respect to the lumen, subsequent to the endoluminal data-acquisition device having acquired the plurality of endoluminal data points while moving through the lumen,
determine a current location of the second endoluminal device with respect to the lumen, anddrive the display to display the stack, and to display within the stack an image of the second endoluminal device at a location within the stack corresponding to the current location of the second endoluminal device.
