Abstract:
1. A multimodality imaging phantom for calibrating an imaging apparatus, comprising: a container having walls allowing a use of the imaging apparatus for imaging the interior thereof, the walls being provided with an inlet and an outlet; a first layer of tissue mimicking material located in a portion of the interior of the container; at least one marker embedded in the first layer, the at least one marker having an acoustic impedance that is 3 to 30 times higher than that of the first layer, an X-ray absorption coefficient that is 3 to 50 times higher than that of the first layer, and a MR axial relaxation time that is 2 to 20 times lower than that of the first layer; and a second layer of tissue mimicking material located in a remaining portion of the interior, the second layer embedding a vessel operatively connected to the inlet and the outlet.
