Abstract: An apparatus for displaying and recording medical images and producing by sketching or drawing line segments creating an electronic virtual road map of a patient's anatomy for use by a physician during an intra-body medical procedure. The apparatus includes among its essential elements, an interventional device providing real time images of body structure of the patient; a medical image acquisition system computer adapted for acquisition of a plurality of medical imaging video signals wherein signals are acquired from a transmitting medical device in the medical device's native resolution having a central processing unit, a display, at least one input device, a storage device, an output device wherein the medical image is displayed on the display; and an image generating device, wherein physician uses the input device to sketch or draw line segments creating virtual road map of patient's anatomy over the medical image.

Abstract: The present invention relates to a process for manipulating data models for the transfer of models between a plurality of software engineering tools (Ta, Tb, Tc, Td, etc.) and for the application of transformation rules to a model, wherein the transformation of data models is carried out by means of gateways (Ba, Bb, Bc, Bd, etc.) which make it possible to convert the format of one tool to the format of another tool by passing through a unique neutral intermediate format (NIM). The present process is remarkable in that the development of the gateways, in accordance with the so-called object-oriented approach, is carried out in an executed language, the gateways being executables which allow the transformation of a data model in several steps activated successively, in a systematic or conditional way, by means of a command language which describes a logic for dynamic concatenation of the steps, concatenation being a named, parameterized procedure.
