Which scan option will yield the best temporal resolution?

The best temporal resolution in a CT scan is determined primarily by the rotation time of the scan and the ability to acquire data quickly and efficiently. Temporal resolution refers to the scanner's capability to capture image data over time, which is critical in imaging dynamic processes such as blood flow or moving organs.

Option A features a rotation time of 0.3 seconds, which is the shortest compared to the other options. A shorter rotation time allows for more rapid acquisition of images, meaning that the scanner can capture a moving object more accurately and with less motion blur, thus enhancing temporal resolution.

The choice of 1.0 mm slices and the use of a bone algorithm also support high-quality imaging, but the primary factor contributing to temporal resolution is the rotation time. Since A has the quickest rotation time, it ultimately leads to the best temporal resolution among the provided options. The milliamperage values affect image quality and dose but do not directly impact the scanner's ability to capture temporal detail as much as the rotation time does.
