Non-invasive method forassessing the densitometric tumor parameters and other structures using CT images

Abstract

The purpose of the work was to study the capabilities of a clinically accessible software method for assessing the densitometric properties of a pathological lesion and other structures of the human body during adapted radio therapy (dynamic observation). To quantitatively assess the densitometric properties of human body structures during dynamic observation, a proprietary program was used, consisting of several subprograms. The versatility of the software method has been demonstrated both for assessing the density characteristics of a tumor during dynamic observation for any cases of visualization of tumor boundaries (including cases of unclear visualization of the tumor boundary) and other structures. Quantitative characteristics of tumor densitometric parameters are presented. The possibilities of using the same method are shown using the example of bone cement material used in oncology, which enters the irradiation field during radiotherapy. The quantitative information content of the method is shown.
