MRI with magnet assembly adapted for convenient scanning of laboratory animals
An animal handling system (AMS), for positioning an immobilized animal in a predefined configuration therein, 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 within an imaging medical device; said system having a proximal portion held out of said imaging device and a distal portion insertable into said imaging medical device, said system comprising
a. at least two tubular members telescopically maneuverable one relative to another; and
b. maneuverable telescopic mechanism provided in said proximal portion and configured for mutually maneuvering said at least two tubular members telescopically maneuverable one relative to another;
wherein said proximal portion is provided with indicia indicating mutual linear and rotational displacement between said tubular members; and
wherein said distal portion accommodates an encapsulable life support system (ELSS) comprising a cradle on which said animal is immobilized, said ELSS is rotatable about an axis of said at least two tubes and translationally moveable along said axis by means of said maneuverable telescopic mechanism such that said animal is accurately and reversibly configured within said medical device thereby optimizing animal analyses.
2. The AMS of claim 1 , further comprising:
a fluid supplying mechanism comprising a anaesthetization gas mask characterized by a cup having a conic cross section and comprising a plurality of apertures located on an outer circumference of said cup, said fluid supplying mechanism is in a continuous fluid communication with at least one of the following:
i. an anaesthetization gas inlet positioned outside the ELSS and an outlet located within the ELSS;
ii. an air suction scavenging device positioned outside the ELSS and an air suction outlet located within the ELSS; and
iii. a plurality of air conditioning tubes; and
an airtight shell enveloping said ELSS;
wherein said airtight ELSS prevents leakage of anaesthetization gas from said ELSS to the outside environment, provides thermal isolation between the outside environment and the air-conditioned ELSS environment and avoid accidental spillage of hazardous materials.
3. The AMS according to claim 2 , wherein said anaesthetization gas mask, said fluid supplying mechanism are adapted by means of size and shape, to ensure anaesthetization of laboratory animals.
4. The AMS according to claim 2 , wherein said anaesthetization gas mask, said fluid supplying mechanism are adapted by means of size and shape, to ensure anaesthetization of laboratory animals.
5. The AMS according to claim 1 , wherein said medical device comprises a magnetic resonance imaging device.
6. A method for positioning an immobilized animal in a predefined configuration within an imaging medical device, comprising:
providing an animal handling system, the animal handling system comprising at least two tubular members telescopically maneuverable one relative to another; and a maneuverable telescopic mechanism configured for mutually maneuvering said at least two tubular members telescopically maneuverable one relative to another,
wherein said system has a proximal portion and a distal portion; said proximal portion is provided with indicia indicating mutual linear and rotational displacement between said tubular members, and said distal portion accommodates an encapsulable life support system (ELSS) comprising a cradle on which said animal is immobilized; and
wherein said method comprises a step of insertion of said distal portion into said imaging medical device; and at least one step of the following: a step of rotating said ELSS about an axis of said at least two tubes and a step of translationally moving said ELSS along said axis by means of said maneuverable telescopic mechanism.
7. The method according to claim 6 , wherein said imaging medical device is a magnetic resonance imaging device.
8. The method according to claim 6 , wherein said animal handling system further comprises an anaesthetization gas mask and a fluid supplying mechanism adapted by means of size and shape, to ensure anaesthetization of laboratory animals.
