Fig. 4: Impedance measurement of eyes in a fresh bovine head.
From: Evaluation of electrical impedance spectroscopy of bovine eyes for early detection of uveal melanoma
a Placement of contact lenses and probes to measure impedance from cornea, (b, c) absolute impedance and phase of right and left eye in a bovine head. The incision and additional muscle tissues into one eye changed the impedance and phase, (d, e) absolute impedance and phase of eyes 5 and 20 h after slaughter time.
