What type of system features a single row of detectors capable of acquiring only one image section for each gantry rotation?

The system that features a single row of detectors capable of acquiring only one image section for each gantry rotation is known as Single-slice CT (SSCT). This type of computed tomography specifically utilizes a single detector array, which limits its capability to produce one image slice per rotation of the gantry. This design is foundational in CT technology and was one of the earliest configurations used in clinical practice.

Single-slice CT systems were very common before the advent of more advanced technologies. Their simplicity allows for straightforward image acquisition and processing, but they do not have the efficiency or speed of multi-slice systems, which produce multiple slices simultaneously. Due to their design, SSCT is mainly applied in scenarios where high-resolution images of a single slice are required at slower acquisition speeds.

The other types of CT systems, such as multi-slice CT, dual-source CT, and sequential CT, involve configurations and technologies that significantly increase the number of slices produced per rotation or utilize multiple source-detector pairs, making them more suited for advanced imaging needs.
