Development of NLS diagnosis for primary duodenal papilloma using the Biophilia Tracker
Recent technological innovations in nonlinear diagnostic equipment and software have led to a fundamental expansion of NLS research applications and improved image quality. A promising direction for the development of NLS diagnostics using the Biophilia Tracker is a multidimensional virtual reconstruction modality of NLS images, allowing visualization of transects and anatomical reconstructions of the study area, which remain invisible during 2D application only scans. This method offers the possibility of data processing, using rotation and scaling, to present the true anatomy of the organ in direct projection. Compared with 2D visualization, 3D NLS scanning has certain technical and practical advantages in the visualization of anatomical and pathological structures. This method allows transecting of acquired images, such as frontal images, or isolating individual regions in fast vision mode. It visualizes the internal structure of parenchymal organs, and if there is an area of influence within the investigation area, the operator can isolate and magnify the parenchymal area to see tissue ingrowth in NLS ultrascanning mode. The Spectral Entropy Analysis (SEA) mode allows the morphological features of the study area to be defined by comparing spectral similarity with etalon processes.
According to T. Guseva et al., 3D NLS is better than standard 2D NLS in studying the anatomical motion of hepatic vessels and bile ducts.
A. Schvack in his work evaluates the utility of 3D NLS scanning in patients with obstructive disease of the bile excretory system. After comparing 3D NLS scans with endoscopic retrograde cholangiopancreatography, it was noted that 3D NLS scans were nearly as efficient and informative as endoscopic retrograde cholangiopancreatography in assessing biliary pathology.
