Xenon gas detectors are not utilized with multi-detector computed tomography (MDCT) systems. MDCT relies on the use of X-ray technology to create detailed cross-sectional images of the body. The detectors in MDCT systems are designed specifically to measure the intensity of X-ray photons that pass through the body after being generated by the X-ray tube.

Xenon gas detectors typically involve a different principle, where the presence of xenon gas can be used for various applications, such as in nuclear medicine or specialized imaging techniques where it acts as a contrast agent rather than in conventional CT imaging. Therefore, the incorporation of xenon gas detectors with MDCT does not align with the operative principles of X-ray imaging, leading to the conclusion that these detectors are not suitable for use in this context.

The other choices suggest scenarios where one might think xenon gas could somehow fit into MDCT workflows, but the established technology and imaging processes do not support those applications. Thus, the correct understanding is that MDCT systems solely utilize X-ray-based detection methods.
