Abstract
An ultrasound phantom comprising: water; agar; a thickening polysaccharide; and a water-retention auxiliary agent, wherein when a first phase transition point is defined as a temperature at which an aqueous dispersion liquid of the agar is solated by temperature raising and becomes a solated aqueous solution of the agar, and a second phase transition point is defined as a temperature at which the solated aqueous solution of the agar is gelated by temperature lowering, the thickening polysaccharide does not have a phase transition point at which an aqueous solution of the thickening polysaccharide is gelated by temperature lowering in a temperature range from the second phase transition point to the first phase transition point, and a polar term δP of Hansen solubility parameters of the water-retention auxiliary agent is 13.0 MPaor more.
