摘要： This invention provides an ultrasonic phantom that can respond to different ultrasonic intensities. Such ultrasonic phantom comprises a gel comprising a low-boiling compound in the form of droplets sealed therein. The invention also provides an assay technique using such phantom. This invention enables regulation of components of droplets, droplet size, and the ultrasonic intensity at which droplets are vaporized upon mixing of droplets with different sizes. This enables visualization of whether or not ultrasound beams that exceed relevant different ultrasonic intensities have been applied.

摘要： Provided is a tissue mimicking phantom technology capable of controlling an ultrasonic echo intensity and hardness and offering excellent stability. A tissue mimicking phantom includes a first portion and a second portion which is incorporated in the first portion and whose hardness and/or ultrasonic echo intensity is different from that of the first portion. The first portion and second portion are gel structures that are formed with a covalent bond of macromolecular strands or a chemical bond that is as strong as the covalent bond. The gel structure has a solid scatterer (for example, metal-oxide microparticles) dispersed therein. The first portion and second portion exhibit mutually different hardness levels and ultrasonic echo intensities.
