Abstract
A ramrod for cleaning the bore of an MRI device, including: a head with a cross-section substantially identical in shape to the MRI bore's cross-section, the cross section having size slightly smaller than the MRI's bore's cross-section to fit snugly and movably within the bore, the head having at least one end, the head having a longitudinal axis; and a rigid extended longitudinal body rigidly connected to the at least one end, the body having a longitudinal axis. The passage of the ramrod through the bore removes particulates from the bore.
Claims32
A ramrod for cleaning the bore of an MRI device, comprising:
- a. a head with cross-section substantially identical in shape to said MRI bore's cross-section, said cross section having size slightly smaller than said MRI's bore's cross-section to fit snugly and movably within said bore, said head having at least one end, said head having a longitudinal axis;
- and
- b. a rigid extended longitudinal body rigidly connected to said at least one end, said body having a longitudinal axis;
- wherein passage of said ramrod through said bore removes particulates from said bore.
A standard of care protocol for cleaning the bore of an MRI, comprising
- a. providing a ramrod with a substantially cylindrical head with cross-section substantially identical in shape to said MRI bore's cross-section, said cross section having size slightly smaller than said MRI's bore's cross-section to fit snugly and movably within said bore, said head having at least one end, said head having a longitudinal axis;
- and a rigid extended longitudinal body rigidly connected to said at least one end, said body having a longitudinal axis;
- b. specifying at least one cleaning criterion;
- c. waiting until at least one said at least one cleaning criterion is fulfilled;
- and
- d. reciprocating said ramrod through said bore, thereby maintaining the cleanliness of said bore;
- wherein by reciprocating said ramrod through said bore particulates from said bore are removed.
A method of providing a homogeneous magnetic field in the Volume of interest (VOI) of an MRI device, comprising steps of:
- a. providing a ramrod with a substantially cylindrical head with cross-section substantially identical in shape to said MRI bore's cross-section, said cross section having size slightly smaller than said MRI's bore's cross-section to fit snugly and movably within said bore, said head having at least one end, said head having a longitudinal axis;
- and a rigid extended longitudinal body rigidly connected to said at least one end, said body having a longitudinal axis;
- and
- b. reciprocating said ramrod through said bore;
- thereby removing metal debris from said bore and providing a homogeneous magnetic field in the VOI.
