The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

READI with EMC2 applied to the TOBE-based FORCES sequence fully restores images corrupted by probe motion and recovers tissue speckle and boundaries in images of a beating heart phantom.

C2weakest assumption

That motion between the low-resolution READI sub-images can be estimated accurately enough from their differences to allow reliable warping and compounding without introducing new artifacts.

C3one line summary

READI with EMC2 restores high-resolution ultrasound images from motion-corrupted Hadamard-encoded TOBE array data by generating and aligning multiple low-resolution sub-images.
