Patent CA-2278277-A1 (CA)
Inventor: BRINK ROBERT H
IPC: G01V1/16
Filed: 1999-07-20
Abstract: An apparatus and method for selectively locking the orientation of seismic data sensor capable of detecting data regarding a seismic event. A gimbal orients the sensor into a selected vertical orientation, and a switch operates a clutch to lock the sensor from further movement. A controller can identify a time interval correlating with a seismic event, and the controller operates the switch to lock the sensor before the seismic event begins. After the completion of the seismic event, the switch unlocks the sensor so that the gimbal can permit reorientation of the sensor. The locking mechanism eliminates noise associated with moving gimbal components and is suitable for land based and marine seismic operations.

Filed: 1998-02-23
Abstract: A computer system and a computer-implemented method are provided for interactively displaying a three-dimensional rendering of a structure having a lumen and for indicating regions of abnormal wall structure (32). A three-dimensional volume of data (34) is formed from a series of two-dimensional images (33) representing at least one physical property associated with the three-dimensional structure. An isosurface of a selected region of interest (37) is created by computer from the volume of data based on a selected value or values of a physical property representing the selected region of interest (35). A wireframe model of the isosurface (38) is generated by the computer wherein the wireframe model includes a plurality of vertices. The vertices (40) of the wireframe model are then grouped into populations of contiguous vertices having a characteristic indicating abnormal wall structure by the computer (44). The wireframe model is then rendered by the computer in an interactive three-dimensional display to indicate the populations of abnormal wall structure (50).
