What is the name of the electronic components in a CT system responsible for measuring transmitted x-radiation absorbed by the detectors?

The electronic components in a CT system that measure the transmitted x-radiation absorbed by the detectors are referred to as the Data Acquisition System (DAS). The DAS plays a crucial role in acquiring and processing the signals generated by the detectors after they detect the x-rays passing through the patient. When x-radiation is transmitted through the patient, the detectors convert the x-ray photons into electrical signals. The DAS then digitizes these signals for further processing.

This system also orchestrates the data flow and timing between the x-ray tube and the detectors, ensuring that the information is collected accurately and efficiently. The accuracy and speed of the DAS significantly influence the overall quality of the images produced during a CT scan.

In contrast, the other components mentioned, such as the Control Unit, Image Reconstruction Unit, and Power Supply Unit, serve different functions within the CT system. The Control Unit manages the operations of the CT system, the Image Reconstruction Unit processes the acquired data to form images, and the Power Supply Unit provides the necessary electrical power to various components of the CT system. These functions, while essential to the overall operation of the CT scanner, do not directly involve the measurement of x-radiation or the functioning of the detectors.
