摘要： The present invention provides an anatomical visualization and measurement system comprising a first database that comprises a plurality of 2-D slice images generated by scanning a structure. The 2-D slice images are stored in a first data format. A second database is also provided that comprises a 3-D computer model of the scanned structure. The 3-D computer model comprises a first software object that is defined by a 3-D geometry database. Apparatus is provided for selecting a particular 2-D slice image from the first database. Apparatus is also provided for inserting a second software object into the 3-D computer model so as to augment the 3-D computer model. The second software object is also defined by a 3-D geometry database, and includes a planar surface. The second software object is inserted into the 3-D computer model at the position which corresponds to the position of the selected 2-D slice image relative to the scanned structure. Apparatus is also provided for texture mapping the specific 2-D slice image onto the planar surface of the second software object. Display apparatus is provided for displaying an image of the augmented 3-D computer model so as to simultaneously provide a view of the first software object and the specific 2-D slice image texture mapped onto the planar surface of the second software object. Apparatus and method are also provided for determining structural dimensions and volumes using appropriate scanned 2-D slice image information. The apparatus and method are particularly well suited for determining dimensions with respect to structures which follow a tortuous path and/or have a complex branching structure, e.g., vascular structures. Among other things, the present invention permits an appropriate set of scanned 2-D images to be assembled into a 3-D database, information regarding selected structural features to be segmented out of the 3-D database, and measurements to be made based on these structural features. In addition, the present invention permits a set of oblique images to be generated based on these structural features, which oblique images may themselves be used for measurement purposes.

摘要： The present invention provides for a secure, two-way transmission of medical data over the Internet and through the hospital's firewall using push and pull mechanisms. More particularly, the present invention utilizes standard SSH technology and the rsync and scp protocols to enable secure, cost-effective data transmission over the Internet. The hospital firewall is traversed through the use of an agent located behind the hospital's firewall. The agent utilizes a push mechanism to push the raw scan data through the firewall and over the Internet to the outside third party; and the agent uses a pull mechanism to reach through the firewall and over the Internet to retrieve the data processed by the outside third party. In other words, the present invention transfers data from the hospital to the third party by initiating a data push mechanism from behind the hospital firewall; and transfers the processed data from the outside third party back into the hospital by initiating a data pull mechanism from behind the hospital firewall. The aforementioned agent acts as a broker for the foregoing data transmission and also encodes how the data should be handled once it is received on the hospital side.
