摘要：
The claimed utility model relates to the field of medical technology, namely, to means of monitoring the quality parameters of images obtained on a computer tomograph, which allow to evaluate the effectiveness of algorithms and methods for suppressing artifacts from metal structures. The closest to the claimed technical solution is the phantom of the Gammex company (Ballhausen et al., For metal artifact reduction. Radiation Oncology. 2014； 9: 114-124； PCT / US 2017/063083. Automated detection and identification of phantoms) with modified configuration for the study of algorithms for suppressing metal artifacts. This phantom is a disk filled with solid material - water equivalent. The volume of the phantom contains cells that are filled with substances with different x-ray densities, and an insert made of titanium is placed in one of the cells. The disadvantages of this prototype is the presence in the phantom of a solid material - water equivalent, which can not be replaced by samples that mimic other fabrics. In addition, the design does not provide for imitation of adipose tissue. The technical problem to be solved by the claimed utility model is to assess the effectiveness of using various algorithms for reducing the level of artifacts from metal structures when it is possible to simulate various parameters of the patient's body. The solution of the technical problem is provided by a number of distinctive essential features, namely the presence of tanks with control substances of different x-ray density (in the range corresponding to the range of x-ray densities of human tissues), with the possibility of replacing the substance filling the internal volume of the phantom. In addition, the inventive device differs from analogs in the presence of paraffin linings, which allow to simulate adipose tissue.Заявляемая полезная модель относится к области медицинской техники, а именно к средствам контроля параметров качества полученных на компьютерном томографе изображений
