A perfusion chamber for use in a phantom including a waterproof housing containing a porous material, the porous material defining fluid paths between pores and tubular channels within the porous material; and a reservoir for use in a phantom, a pump mechanism for use within the bore of an MRI scanner, a phantom for use in an MRI scanner, and a method for calibrating a scanning device.

Perfusion phantom for MRI and an apparatus, system and method for validating MR images of a phantom

A perfusion chamber for use in a phantom includes a waterproof housing containing a porous material defining fluid paths between pores and tubular channels within the porous material. A reservoir for use in a phantom, a pump mechanism for use within the bore of an MRI scanner, a phantom for use in an MRI scanner, and a method for calibrating a scanning device are disclosed. Also disclosed is apparatus for validating images of a phantom that includes: one or more sensors for coupling to a phantom to be imaged; a control/logging system configured to: collect sensor data during imaging of the phantom and pass this as input to a computer model; compare the image data with reference image data produced using the computer model; and return a pass score depending on the comparison. A system and method for verifying images of a phantom are also disclosed.

A phantom for use in an MRI scanner includes an outer housing and a plurality of vessels located within the outer housing, where each of the vessels contains a material. The value of a property of the material at a particular temperature is different for each of the vessels. The phantom also includes a phase change material between the outer housing and the vessels. Also provided are a method for manufacturing a phantom, a method for obtaining calibrated measurements from non-calibrated images using a phantom, a system for obtaining calibrated measurements from non-calibrated images, and a coil assembly for use in an MRI scanner.

Phantom for multi-parametric calibration in magnetic resonance imaging

Intravascular contrast agents are provided by Gd-chelates modified so as to comprise an amino acid unit attached to the chelate via a linker group suitably selected from Calkylene and Calkynylene. The chelates may be used as an intravascular contrast agent for MRI. Certain embodiments demonstrate enhanced relaxivity and good levels of signal enhancement.
