Freezing of gait (FOG) is an episodic gait disturbance affecting locomotion in Parkinson's disease. As a biomarker to detect FOG, the Freeze index (FI), which is defined as the ratio of the areas ...

In this work, we experimentally demonstrate an approach to estimate the PSF of AIM imaging systems by averaging PSF estimates from multiple point targets using a shift-and-add method in a 38-GHz ...
