Question
Most current multi-detector CT scanners (64-, 256- and 320-slice scanners) have similar spatial resolution, however the increased detector slices and larger detector width allow more coverage of the heart in each heartbeat. Dual source CT scanners consist of two X-ray tube sources leading to improved temporal resolution to 75 ms. Spatial resolution is how close two objects can be discernible from each other. Temporal resolution is how fast an image could be acquired such that motion does not create image blurring, similar to the shutter speed of a camera
