A PERFUSION PHANTOM FOR MRI AND AN APPARATUS, SYSTEM AND METHOD FOR VALIDATING MR IMAGES OF A PHANTOM

摘要

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.
