THERMOGRAPHY SCREENING DISORDERS AND INJURIES OF PERIPHERAL NERVES Thermography Atlas

Medical thermography is a non-invasive non-contact diagnostic method that allows to measure thermal radiation and visualize its distribution on the human body surface. The proposed atlas of thermograms is dedicated to the thermography diagnostic of disorders and injuries of peripheral nerves. Diagnostic criteria itself are based on the changes of normal temperature distribution in the area which is innervated by the disfunction nerve. All cases of pathology confirmed by reference methods and clinical data. The edition can be useful for neurologists, neurosurgeons, rehabilitation specialists, physiotherapists who treat the patients with the peripheral nerve pathology

Macro-Modelling of Rib-Knitted Tubular Parts

The aim of the research was to improve the process of knitted products design. The use of modern software helps us predict the physical and mechanical behaviour of materials, using their three-dimensional models. A macro-model of rib-knitted tubular parts was developed in the study. This model allows its implementation into algorithms, describing the peculiarities of the stretching process. Recent findings in the field of 3D modelling and simulation of knitwear behaviour aim at working with models of different scales of structural hierarchy. The use of macro-models provides the opportunity to simplify the geometry and significantly reduce the time required for simulation. Rib stitch structures are among the most popular weft-knitted ones. When using threads of usual stretchability (with breaking elongation that does not exceed 10–12%), the stretchability of some rib stitch structures in the course-wise direction can reach up to 350% and even more. When stretched in the course direction, rib-knitted stitches undergo a number of stages. The stretching process includes: decreasing the width-wise curling; mutual shifting of knit and purl stitches; reducing the curvature of the loop feet and loop heads; pulling the yarn from the loop legs to the loop feet; stretching of the yarn. The assumption was made that such parts of knitted garments as cuffs and borders on sweaters, cuffs on socks, where rib stitch patterns are used, can be described as thin-walled elastic shells. A part of a human body surface, covered with a rib-knitted garment part, can be approximated by a truncated cone. The mid-surface of the shell can be represented as a ruled surface created upon a set of Bezier curves, located along the circumference of the upper and lower bases of the truncated cone. The mathematical description, elaborated in the course of the research, was used for the computer program LastikTube, which was developed to create 3D macro-models of ribbed tubular garments.

Investigation of microwave sensor and integrate with polydimethylsiloxane for medical imaging application

The small-sized wideband antenna is one of the antennas used in the medical field to detect body tissue. The antenna's direct contact with the human body causes reflected signal due to the high body coupling, and the narrower bandwidth tends to reduce the data transfer rate in transmission. Therefore, this paper aims to design a wideband antenna with wearable properties operated in the frequency range of 3 GHz to 6 GHz. The antenna is designed with a rectangular-shaped patch with notches and the t-slot shaped partial slot ground. The connected speech test (CST) studio suite software is used to design and optimize the miniature antenna, which measures 24 mm (W) x 38 mm (L) x 0.168 mm (H). The antenna is then embedded with polydimethylsilixane (PDMS) at the top half of the antenna with the dimension 24 mm (W) x 19 mm (L) x 1 mm (H) and also fully occupied. The antenna is configured with the bending capabilities to adapt the human body surface at an angle of 30º. The antenna is having the benefits of small size, cost-effective, and easy to fabricate. The antenna design can effectively detect unusual body tissue, and it safe to be used.

Рossibilities of the Thermography in Early Diagnostics of Bleb Scarring (Prelimenary Report)

Thermography is the method of noninvasive registration of visible image of the own infrared radiation of the human body surface by special devices. The physiological basis of its application in medical diagnostics is the amplification of infrared radiation intensity from pathologic spots that is connected with the enhancement of blood supply and metabolism.Purpose. To study the possibilities of thermography for functional bleb status assessment, for early diagnostics of bleb scarring processes and for definition of needling indications.Patients and methods. There were executed 32 thermography (32 patients and eyes) of blebs in 7 days after minimally invasive sinustrabeculectomy. Authors used thermal imaging Тesto 875-2i with SuperResolution technology and telephoto lens 9°×7°. The bleb area and temperature were studied With IRSoft and Universal Desktop Ruler programs. Intraocular pressure (corneal compensated) (IOPcc) was measured with Ocular Response Analyzer®, ORA.Conclusion. The study has shown the direct correlation dependence between bleb functional activity and its thermographic characteristics (area and temperature).

Selecting Target Range with Accurate Vital Sign Using Spatial Phase Coherency of FMCW Radar

Respiration and heartbeat are basic indicators of the physiological state of human beings. Frequency-modulated continuous wave (FMCW) radar can sense micro-displacement in the human body surface without contact, and is used for vital-sign (respiration and heartbeat) monitoring. For the extraction of vital-sign, it is essential to select the target range containing vital-sign information. In this paper, we exploit the coherency of phase in different range-bins of FMCW radar to effectively select the range-bins that contain accurate signals for remote monitoring of human respiration and heartbeat. To quantify coherency, the spatial phase coherency (SPC) index is introduced. The experimental results show that the SPC can select a range-bin containing more accurate vital-sign signals than conventional methods. This result demonstrates that the proposed method is accurate for monitoring of vital signs by using FMCW radar.

Filling cavities in point clouds representing human body surface using Bezier patches

In this paper we introduce a cavity reconstructing algorithm for 3D surface scans (CRASS) developed for filling cavities in point clouds representing human body surfaces. The presented method uses Bezier patches to reconstruct missing data. The source of input data for the algorithm was an 8-directional structured light scanning system for the human body. Typical 3D scan representing human body consists of about 1 million points with average sampling density of 1 mm. The paper describes the complete scan processing pipeline: data pre-processing, boundary selection, cavity extraction and reconstruction, and a post-processing step to smooth and resample resulting geometry. The developed algorithm was tested on simulated and scanned 3D input data. Quality assessment was made based on simulated cavities, reconstructed using presented method and compared to original 3D geometry. Additionally, comparison to the state-of-the-art screened Poisson method is presented. Values’ ranges of parameters influencing result of described method were estimated for sample scans and comprehensively discussed. The results of the quantitative assessment of the reconstruction were lower than 0,5 of average sampling density.

The Meridian-like High Thermal Line as the Evidence on Existence of Meridians in Human Body

Background; The acupuncture meridian is the channel through which Qi & Blood flow, and acupuncture is having many thousands year history for treating various illnesses. However, there was no powerful evidence to prove the existence of meridians until now. Objectives; The purpose of this study is to explain that the meridian-like high thermal line (MLHTL) is the powerful evidence to prove the existence of meridians in human body. Methods; The meridian-like high thermal line inducing and the disease cure effect in the target organs connected along the meridians by the mineral pulse light stimuli, was researched and analyzed. Results; The meridian-like high thermal lines were induced along the classic meridians course at the human body surface, and simultaneously the internal refractory diseases such as nephrotic syndrome and angina pectoris were treated in the target organs connected along the meridians without drug use by the mineral pulse light stimuli. Conclusions; The meridian-like high thermal line is the powerful evidence to prove the existence of meridians in human body. From now on, MPL stimulator (Version 1) can induce MLHTL, and can show the non-drug cure effect in target organ connected along MLHTL.
