Embodiment Construction

[0029] FIG. 2 is a block diagram schematically illustrating an imaging system 30 according to the present invention. Imaging system 30 includes a control device 31 (typically, a suitably programmed computer), a display screen 32 , a data source 33 and a user input device 34 . The data source 33 may be a memory containing data sets, but may also include an X-ray radiation device or the like. User input device 34 may include a keyboard, but preferably, includes a mouse. In a preferred embodiment, imaging system 30 has a graphical user interface that includes a pointer 50 displayed on screen 32 that can be moved by user commands. In addition, the user can input a selection command, for example, by clicking a mouse button, to select an object at which the pointer is pointing at that time. Furthermore, moving the pointer will move the selected object (drag). Since the concept of clicking and dragging is well known, it need not be repeated here.

Abstract

A method for imaging a blood vessel (2) comprises the steps of: providing a two-dimensional view of the vessel; calculating a region of interest (40); defining a characterizing base path (13) of the vessel; within the region of interest (40), calculating a base line (22) perpendicular to the base path (13); along the base line (22), determining a transition where the base line intersects a side edge (2a, 2b) of the vessel; finding such transitions for many base lines; considering the collection of transitions as defining a side edge (27, 28) of the vessel; allowing a user to input an amendment command, and in response to receiving a user input amendment command, amending at least a portion of the region of interest and repeating the calculation with the amended region of interest.

Description

technical field [0001] The present invention generally relates to methods of imaging ultralong structures. More precisely, the present invention relates to methods of imaging blood vessels (in humans or animals) in vivo, and will be specifically illustrated in the context of blood vessels. It should be noted, however, that this example should not be seen as limiting the scope of the invention, as the gist of the invention can also be used to image other structures. In any event, a superlong structure such as a blood vessel is characterized by a centerline that can be drawn along a path, which can be straight or curved, and whose width is constant along the length of the centerline , but the width can also vary along the length of the centerline. Background technique [0002] The imaging process typically includes the steps of displaying a two-dimensional image derived from a three-dimensional volume. This two-dimensional image is obtained by transmitting radiation (typica...
