MRI WITH MAGNET ASSEMBLY ADAPTED FOR CONVENIENT SCANNING OF LABORATORY ANIMALS WITH AUTOMATED RF TUNING UNIT

摘要

An animal handling system (AMS), for positioning an immobilized animal in a predefined configuration therein, comprising an automated tuning unit, including: a proximal portion, held outside a medical device including: at least one inner shaft, and at least one outer shaft, the at least one inner is telescopically maneuverable within the at least one outer shaft providing a variable telescopic mechanism; and a distal portion including: a configurable encapsuable life support system (ELSS), the ELSS is rotatable about a longitudinal axis of the at least outer shaft and the at least inner shaft and translationally moveable parallel to the longitudinal axis by means of the maneuverable telescopic mechanism.

1. An animal handling system (AMS), for positioning an immobilized animal in a predefined configuration therein, comprising:
a. a proximal portion, held outside a medical device comprising:
i. at least one inner shaft, andii. at least one outer shaft, said at least one inner is telescopically maneuverable within said at least one outer shaft providing a variable telescopic mechanism; b. a distal portion comprising: a configurable encapsuable life support system (ELSS), said ELSS is rotatable about a longitudinal axis of said at least outer shaft and said at least inner shaft and translationally moveable parallel to said longitudinal axis by means of said maneuverable telescopic mechanism; said proximal portion further comprising indicia indicating a linear displacement and a rotational displacement of said ELSS, such that said ELSS is accurately and reversibly configured within said medical device thereby optimizing animal analyses. wherein said medical device comprises an MRD having a first input port; a second input port; at least one magnetic source providing a magnetic field; and a resonance assembly comprising at least one RF source coil; and wherein said AMS further comprises an automated tuning unit comprising a motor configured to dislocate position of said RF coil, and thus match said RF coil's resonance frequency to said magnetic field's frequency in an automated manner.
