Figure 6 -

A) Schematic of the monitoring microtissue implantation into the calvarial defect using high-resolution ultrasound imaging. B) 3D ultrasound image reconstructions showing the injection of microtissues through the skin into the calvarial defect (series i-iv). C) Correlation of mineral content of microtissues and the midband fit parameter generated by spectral ultrasound imaging (SUSI). D) Heat maps of acoustic concentration generated by SUSI, showing spatial distribution and concentration of mineral in the microtissue implants.
