The MiniWB57 probe with an outer diameter of 57 mm has been developed for micro-imaging studies of larger objects or animals in wide bore magnets (89 mm ID). The probe is combined with the Mini0.75 gradient system (0.75 G/cm/A).
The MiniWB57 probe is comprised of a probe body, exchangeable single or double frequency volume resonators of 40 mm inner diameter and a separate Animal Handling System which offers increased flexibility for in-vivo studies because the position of the animal can be changed relative to the rf-coil, while the animal remains inside the magnet.
Electrical connections with rf filters are available in the Animal Handling System for connecting a body temperature sensor and ecg electrodes to monitor the heart beat and to enable cardiac triggered data acquisition. Tubes are built in with Luer connectors from the bottom of the probe to the region of the rf-coils for the application of anesthetics and for the connection of a pressure based respiratory sensor for controlling the animal and to acquire respiration triggered images without motion artifacts.
