1. An apparatus (200) to assist in moving the device (117) in the network (115) tubular structures, comprising: - a module (205) input configured to receive a reference current image projection (190a), resulting in a first direction while the projections when the device is placed on the web of tubular structures, thus projecting an image when displayed indicates the imprint apparatus, - a processor (201) configured to use the current position in the image print and network model in order to extract, without using the obtained three-dimensional image data network support projection image (170a, 170i) of the sequence (170a-c) previously acquired two-dimensional projection image, and is extracted sub-image when displayed indicates at least a partial fingerprint (115a) network (115), wherein a recovered auxiliary image provides a view along the second projection direction for the network in the study area, which is currently located device - driver (270), graphical displays configured to generate for display on-screen graphic panel (280), which includes the current projected image and an auxiliary projection image, wherein the device is configured to update the graphical panel when a new projection image (190b) in the module (205) input, wherein the update panel in this case involves a new projection image (190b) and the new extracted auxiliary projection image (170j-k) .2. Apparatus according to claim. 1, wherein the plurality of two-dimensional projection1.
