Abstract
A MRI quality assurance phantom with a base and a vertical body mounted on the base. At lease one of the base and the vertical body have a housing made of a MRI invisible material and enclose a sealed reservoir filed with a MRI signal producing material. The vertical body has a generally planar face with one or more attachment points thereon for attachment of one or more accessories to the face of the vertical body. The interior walls of the housing, defining the shape of the sealed reservoir, have one or more defined structures formed thereon, suitable for image quality testing.
Claims22
A MRI quality assurance phantom, comprising a base and a vertical body mounted on the base, the vertical body having a housing made of a MRI invisible material and enclosing a sealed reservoir filed with a MRI signal producing material, wherein the vertical body has a generally planar external face with a plurality of attachment points thereon for attachment of one or more accessories to the exterior of the face of the vertical body at one or more of a plurality of known positions relative to the vertical body, wherein the housing has parallel and generally planar interior walls defining a generally disc-shaped sealed reservoir with a diameter and a thickness less than the diameter and the interior walls having one or more defined structures formed thereon.
A MRI quality assurance phantom, comprising a base and a vertical body mounted on the base, the vertical body having a housing made of a MRI invisible material and enclosing a sealed reservoir filed with a MRI signal producing material, wherein the vertical body has a generally planar face,
- wherein the housing has parallel and generally planar interior walls defining a generally disc-shaped sealed reservoir with a diameter and a thickness less than the diameter and the interior walls having one or more defined structures formed thereon,
- wherein the one or more defined structures comprises a plurality of defined structures located within a plurality of image quality zones spaced apart within the plane of the sealed reservoir, and
- wherein each image quality zone contains a plurality of defined structures, comprising modulation transfer function resolution structures and slice thickness ramps.
A MRI quality assurance phantom, comprising a base and a vertical body mounted on the base, the vertical body having a housing made of a MRI invisible material and enclosing a sealed reservoir filed with a MRI signal producing material, wherein the vertical body has a generally planar face,
- wherein the housing has parallel and generally planar interior walls defining a generally disc-shaped sealed reservoir with a diameter and a thickness less than the diameter and the interior walls having one or more defined structures formed thereon,
- wherein the base has a housing made of a MRI invisible material and enclose a sealed reservoir filed with a MRI signal producing material, and
- wherein the base has a generally planar top surface having an X-shaped recess thereon.
