Abstract

The invention provides a phantom preparation method. The phantom preparation method comprises the steps of preparing at least one polyvinyl alcohol solution containing scattering particles and / or at least one polyacrylamide hydrogel containing the scattering particles; putting the polyvinyl alcohol solution and / or the polyacrylamide hydrogel in a mold so as to form a phantom. Since a polyvinyl alcohol hydrogel formed by the polyvinyl alcohol solution and / or the polyacrylamide hydrogel are high in strength, wide in range of elastic change and stable in property during use and storage, the phantom formed by the polyvinyl alcohol hydrogel and / or the phantom prepared through a polymerization reaction of the polyacrylamide hydrogel with a curing agent are also high in strength, wide in range of elastic change and stable in property during use and storage.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical polymer materials, in particular to a method for preparing a phantom. Background technique [0002] With the development of society and the improvement of people's living standards, unhealthy diet has made liver disease, especially chronic liver disease, an important factor threatening people's health. [0003] Pathological changes in biological tissues are often accompanied by changes in their mechanical properties, such as hardness, which have been confirmed and studied in various tissues. For example, this tissue characteristic is used in the examination of tissue lesions such as breast lesions, prostate cancer, and carotid artery vulnerable plaques. Similarly, the progression from liver fibrosis to cirrhosis caused by chronic liver disease is also accompanied by changes in liver stiffness from small to large; liver cancer usually presents as a lesion that is harder t...
