The effect of tube focal spot size and acquisition mode on task-based image quality performance of a GE revolution HD dual energy CT scanner

•In-plane spatial resolution degrades at a lower image contrast.•In-plane spatial resolution degrades with increasing focal spot size.•Image noise increases in high resolution mode.•Noise texture is altered among standard, high resolution and dual energy modes.•Detectability degrades with increasing...
