A dual-source CT scanner is characterized by its two sets of x-ray tubes and two corresponding sets of detector arrays. This design allows for enhanced imaging capabilities, such as faster acquisition times and improved temporal resolution.

Having two x-ray tubes working simultaneously enables the scanner to capture images in a shorter time frame than a single source, which is particularly beneficial for imaging moving objects, like the heart. This can minimize motion artifacts and improve image quality, enabling physicians to more accurately assess conditions with dynamic processes.

The simultaneous operation of two detector arrays ensures that the data collected is comprehensive, leading to improved image reconstruction techniques and the ability to produce high-resolution images in various clinical situations. This unique configuration differentiates dual-source systems from traditional single-source systems that are limited to one tube and one detector array, significantly enhancing the effectiveness of the imaging process.
