Figure 1: Ultrasound biomicroscopy integrated mechanical support with rail system. The microinjection system for visualization and guidance of injection and extraction procedures in real time. Ultrasound probe is mounted on a system securing the probe in a stationary position when the ultrasound scan is in the desired image plane. After anesthesia, the mouse is positioned on a termoregulated pad to monitor ECG and temperature (with endorectal probe) and ensure mouse comfort during imaging.
