Fracture Visualization and Quantification Using Helical CT Scan Technology*
Fracture characteristics—such as orientation, type, fluid storage capability, and permeability—are complex yet essential information for understanding fractured reservoirs. Fractures are often perceived as permeable pathways, although many fractures partially or completely inhibit permeability within a reservoir. For example, opening-mode fractures (joints) may be partially or entirely sealed h...
متن کاملThree-dimensional images by helical CT scan with intra-arterial injection of diluted contrast medium.
Eighty-seven patients with primary or metastatic brain tumors who were admitted to the National Cancer Center Hospital since April 1996, underwent a helical CT scan during cerebral angiography using the IVR-CT system (Toshiba Medical Systems, Tokyo, Japan), which comprised a digital subtraction angiography system (KXO-80C/DFP-2000A) and a helical CT scanner (X-Vision, Toshiba Medical Systems, T...
متن کاملMulti-slice helical CT: scan and reconstruction.
The multi-slice CT scanner refers to a special CT system equipped with a multiple-row detector array to simultaneously collect data at different slice locations. The multi-slice CT scanner has the capability of rapidly scanning large longitudinal (z) volume with high z-axis resolution. It also presents new challenges and new characteristics. In this paper, we study the scan and reconstruction p...
متن کاملAge Differences of Human Frontal Sinus Measurements using CT Scan
Background and Objectives: The frontal sinus is regarded as one of the human paranasal sinuses located in the frontal bone as a triangular-shaped cavity, which originates as separated space from the anterior ethmoid cells. Computed Tomography (CT) is a completely non-destructive technique that uses a high density of contrast to identify the air inside any bony sinus with soft tissue demarcated ...
