Task-driven imaging framework showing joint optimization of the orbital tilt, tube current modulation, and view-dependent reconstruction kernel. (a) Detectability index for the NPWEI observer model computed as a function of gantry tilt angle for the various imaging strategies. (b) Axial and sagittal reconstructions showing visibility of the spherical stimulus for conventional unmodulated acquisition (at 0° gantry tilt) and task-driven acquisition (with jointly optimized gantry tilt of −20°).
