| show | overlapping reconstruction
🗑
|
||||
| Image data are used to stacked cross-sectional slices and generate an image in a plane or orientation different from the prospective image. Also called image rendering | show 🗑
|
||||
| This method requires that the operator input the criteria, such as the thickness of the MPR, the plane desired, and the number or incrementation of the resulting planar images | show 🗑
|
||||
| show | real-time MPR

| 3D technique that selects voxels with the lowest value to display | show 🗑
|
||||
| A 3D imaging technique that creates a semitransparent representation of the imaged structure. A advantage of this is that all voxels contribute to the image, allowing the image to display multiple tissues and show their relationship to one another | show 🗑

| show | opacity value
🗑
|
||||
| A form of volume rendering designed to reveal the inside of the lumen of a structure. The technique is also called virtual endoscopy, virtual bronchoscopy, and virtual colonoscopy | show 🗑

|
||||
| show | segmentation errors
🗑
|
||||
| When smooth objects, such as the aorta, appear on the reformatted image to have edges that resemble a flight of stairs. The result when wide slices are used as source images. | show 🗑

|
||||
| Refers to networks that are linked by a physical connection | show 🗑
|
||||
| refers to networks that use radio waves to transmit data between computers | show 🗑
|
||||
| show | topology
🗑
|
||||
| Connections used to attach computers to the network, consisting of cables that are made up of twisted pairs of copper wire | show 🗑
|
||||
| Comps in this model are either classified as servers or clients. A server is a comp. that facilitates comm btw & delivers info to other comp. The server acts on requests from other networked comp. (the clients), rather than from a person inputting it | show 🗑
|
||||
| show | core servers

🗑
|
||||
| Method of image compression in which the image that is then decompressed in an exact replica of the original | show 🗑
|
||||
| Common set of rules and signals that computers on the network use to communicate | show 🗑
|
||||
| Describes an arrangement in which two or more components perform the same task, if one element fails the duplication keeps the system functioning while the failed component is repaired; duplication of data to provide an alternative in case of failure | show 🗑
