A 4D hyperspherical interpretation of q-space

[Display omitted] •Derive a 4D hyperspherical harmonic-based framework to estimate the 3D q-space signal and dODF.•Estimate rotationally invariant q-space indices using our framework, like Po and QIV.•Validate our framework using HYDI-acquired datasets, both synthetic and in vivo.•Compare our framew...
