Fig. 1: Magnetic resonance imaging of microliter, self-standing droplets in real-time.
From: Contact-free magnetic resonance imaging and spectroscopy with acoustic levitation
MR images of an acoustically levitated droplet of hexadecane (~1.34 μL) acquired with (a) FLASH, b True-FISP, and (c) RARE. MR images of an acoustically levitated droplet of water, with an initial volume of ~5.15 μ, over a period of 8.5 min, were acquired with FLASH along the (d) axial (xy), e sagittal (xz), and (f) coronal (yz) planes. The color bar expresses the normalized pixel intensity of the (d–f) subfigures. The time in the inset refers to the period of acquisition. g Average normalized maximum pixel intensity over time. Calculated (h) volume, and (i) aspect ratio of the water droplet from the FLASH MR images, over time.
