Hardware Developments for Radiation Dose Reduction
The evolution of CT has created systems that scan faster, use thinner sections, and cover more patient anatomy in a single rotation. These developments have not only opened the spectrum of CT applications but have also driven the need for new methods of radiation dose reduction. By analyzing the imaging chain from X-ray tubes and collimators to detectors and data acquisition systems, we examine the various hardware-based dose reduction strategies in the modern CT system. As part of a concerted effort between clinicians, physicists, and manufacturers, hardware innovation and system design play a significant role in optimizing the radiation dose in CT.
