Comparison of elastic imaging modalities in the map of detection scale (penetration depth vs spatial resolution). AFM: Atomic force microscopy, MPM: Multiphoton microscopy, BM: Brillouin microscopy, OT-M: Optical tweezers-based microrheology, OCE: Optical coherence elastography, SI: Speckle Interferometry, HI: Holographic imaging, UE: Ultrasound elastography, MRE: Magnetic resonance elastography. This figure was modified based on previous review work [184], [194], [195].
