Abstract: Methods and systems for manually assisted definition of vascular features are described. In some embodiments, a method provides for editing of vascular paths by enabling a user to drag an erroneously segmented region of a selected vascular path into alignment with a more correctly segmented position that is depicted as a blood vessel in a vascular image. The method may use an energy function, defined as a function of position along the segmentation of the selected blood vessel, to determine how a vascular path is to be moved based on dragging motions provided by the user. In some instances, non-zero regions of the energy function are set based on the position of the selected region.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for dynamically enabling customized web content and applications. One or more rules are stored in a database. Default tag code is transmitted to a browser in response to a request from the browser, the default tag code including data that causes the browser to generate a tag module. An update is received from the tag module comprising data indicative of a visitor's interaction with web page content displayed through the browser. A condition associated with a rule from the one or more rules is determined to be satisfied based on the update. An action associated with the rule is performed, comprising transmitting custom targeted tag code to the tag module, wherein the custom targeted tag code includes data that causes the browser, upon execution of the custom targeted tag code by the tag module, to perform an action.
