Zusammenfassung:An MRI phantom having an MRI compatible temperature measurement device having an MRI compatible body containing an MRI compatible fluid, wherein the device senses accurate temperature measurement within an MR Scanner environment using image processing of the contrast in signal between the areas of the image around the device and the fluid contained within the body of the device. The MRI Phantom may further include an internal expansion bladder device accomodating internal changes in pressure within the phantom, wherein the internal expansion bladder device includes frames supporting a pair of spaced membranes defining a chamber filled with a compressible gas.
