Which of the following is a key characteristic of a dual-source CT scanner introduced in 2006?

A dual-source CT scanner is distinguished by its use of two corresponding sets of detector arrays. This design allows for faster image acquisition and improved temporal resolution. By utilizing two x-ray tubes and two sets of detectors, these scanners can collect data from multiple angles almost simultaneously, which is particularly beneficial for imaging dynamic processes like cardiac studies or in patients who may have trouble holding their breath.

The use of dual detectors also enhances the scanner's ability to differentiate between various tissue types and improve image quality, leading to more accurate diagnostics. This capability is vital in complex imaging scenarios where quick acquisition can improve outcomes, particularly in emergency situations. The combination of both sets of detectors contributes to a significant reduction in scan times and the potential for lower doses of radiation exposure to patients, making it a pivotal advancement in computed tomography.
