CT imaging is expanding into applications that demand high spatial resolution to achieve images with sufficient detail for diagnostic confidence. Two leading approaches are shaping this trend: ultra- high-resolution CT (UHR-CT), which uses conventional energy integrating detectors (EIDs) with reduced pixel sizes for greater resolution, and photon-counting CT, which incorporates photon-counting detectors that offer higher resolution through smaller pixel sizes as well as spectral imaging capabilities.
These technological advances require equally advanced X-ray sources. Smaller detector pixels necessitate focal spots that are not only smaller, but also thermally and mechanically stable. In addition, high gantry rotation speeds for complex applications such as heart scans demand mechanically stable focal spots regardless of size. The extra small focal spots have been developed to address the stability needs of daily clinical operations.

High-resolution CT enables precise visualization of fine structures. Applications include:
