Final answer:
Data interpolation is the process of electronically combining signals from adjacent detector elements to produce a reconstructed CT image.
Step-by-step explanation:
The process of electronically combining signals from adjacent detector elements to produce a reconstructed CT image is called data interpolation. In CT imaging, detector elements capture the X-ray signals as they pass through the body. However, the actual spatial resolution of the detector array is limited, leading to gaps between the elements. To fill in these gaps, the signals from neighboring elements are combined through mathematical algorithms and interpolation techniques, resulting in a reconstructed CT image with improved resolution and clarity.
