Fig. 2From: Intravital microscopy for evaluating tumor perfusion of nanoparticles exposed to non-invasive radiofrequency electric fields Panel a RF setup including RF amplifier (1), confocal microscope objective lens (2), anesthesia tubing (3) coming from behind the microscope stage and XYZ servo-controller (4) for the mouse stage (indicated by the red arrow) above the microscope stage. Panel b Positioning of the RF transmission antenna (TX) against the side of the objective lens with TX center point directly below the lens. Lines on the mouse stage indicate optimal positioning of tumor Y-direction location. Panel c. The receiving antenna (RX) is directly opposite the TX, with centers lined up. Yellow arrows indicate the grounding wire connecting copper tape on the mouse stage to the RX, which is itself grounded. The red arrow points to a glass coverslip that locates the tumor in the Z-direction, optionally located by an XYZ positionerBack to article page
