Impact of loss function on reconstruction error distribution in deep learning-based CT image transformation: a Hounsfield unit residual analysis

| Nature Verified
Abstract The loss function is a critical determinant of reconstruction characteristics in deep learning-based CT image transformation, yet its impact on local error distribution remains poorly understood. We compared two 2D U-Net models trained with mean squared error (MSE) or structural similarity index (SSIM)-based loss functions on abdominal CT images from 60 patients (Philips Spectral CT 7500).
