Traditional CT scanners use energy-integrating detectors while photon-counting detectors count individual X-ray photons. Photon-counting detectors offer several potential advantages, including improved image quality, reduced radiation dose, and the ability to distinguish between different energy levels of X-rays.

High-resolution photon-counting CT can very clearly image segmented DBS electrode contacts and directional markers and unambiguously determine lead orientation, with lower radiation than in conventional imaging. This obviates the need for further imaging and may facilitate anatomically tailored directional programming ¹⁾.
