New engineering technologies allow the creation of diagnostic devices for predicting the development of acute tissue ischemia of the extremities and determining the residual time until the removal of the tourniquet, and solving these tasks is particularly relevant during military actions. Acute limb ischemia is a sudden critical decrease in perfusion that threatens the viability of the limb. The incidence...
The paper examines the features of segmentation of the upper respiratory tract to determine nasal air conduction. 2D and 3D illustrations of the segmentation process and the obtained results are given. When forming an analytical model of the aerodynamics of the nasal cavity, the main indicator that characterizes the configuration of the nasal canal is the equivalent diameter, which is determined at...
The project "Implementation of rapid prototyping for modelling the upper respiratory tract in normal and typical pathologies" investigates the urgent problem of improving the reliability of diagnosis and effectiveness of treatment of disorders of the nasal breathing. Possibilities of modern 3D-printing technology for creation of individual natural anatomical models of the upper respiratory...
The Ce3+ ↔ Ce4+ redox dynamics of colloidal nanoceria at hydrogen peroxide (HP) addition is studied using the luminescence of Ce3+ cations. The fast oxidation (Ce3+ → Ce4+) and slow reduction (Ce4+ → Ce3+) phases of nanoceria–oxidant interaction are discussed. Both the phases are mediated by oxygen diffusion within ceria nanoparticles. Laser‐light irradiation with specific wavelengths causes a significant...
Olfactory studies can be a criterion for evaluating rhinosurgical intervention, and olfactory impairment may indicate respiratory impairment. Therefore, the urgent task is to develop an integrated approach to determining respiratory and olfactory disorders. A structural scheme was developed for the method of objective diagnosis of respiratory and olfactory disorders, taking into account the measu,...
Currently, reconstruction of cranial implants using tomography study is necessary. The work is dedicated to the automation of the process of cranial implant reconstruction. We propose a set of image processing operations at three-dimensional reconstruction of cranial prosthesis using symmetry.
