The role of intraoperative OCT (iOCT) in ophthalmic surgery is still a matter of active research and enhancements to integrative technologies. Further research is necessary to better define the specific applications of iOCT that impact surgical decision-making and as such help to achieve better patient outcomes, both in anterior and in posterior segment of the eye. In time to come advancements in integrative systems, OCT-friendly instrumentation, and software algorithms will most likely expand the horizon of iOCT even further.

Opis:
This paper presents analysis of selected noise reduction methods used in optical coherence tomography (OCT) retina images (the socalled B-scans). The tested algorithms include median and averaging filtering, anisotropic diffusion, soft wavelet thresholding, and multiframe wavelet thresholding. Precision of the denoising process was evaluated based on the results of automated retina layers segmentation, since this stage (vital for ophthalmic diagnosis) is strongly dependent on the image quality. Experiments were conducted with a set of 3D low quality scans obtained from 10 healthy patients and 10 patients with vitreoretinal pathologies. Influence of each method on the automatic image segmentation for both groups of patients is thoroughly described. Manual annotations of investigated retina layers provided by ophthalmology experts served as reference data for evaluation of the segmentation algorithm.

Opis:
Hydroxyapatite (HAp) has been attracting widespread interest in medical applications. In a form of coating, it enables to create a durable bond between an implant and surrounding bone tissues. With addition of silver nanoparticles HAp should also provide antibacterial activity. The aim of this research was to evaluate the composition of hydroxyapatite with silver nanoparticles in a non-destructive and non-contact way. For control measurements of HAp molecular composition and solvent evaporation efficiency the Raman spectroscopy has been chosen. In order to evaluate dispersion and concentration of the silver nanoparticles inside the hydroxyapatite matrix, the optical coherence tomography (OCT) has been used. Five samples were developed and examined ‒ a reference sample of pure HAp sol and four samples of HAp colloids with different silver nanoparticle solution volume ratios. The Raman spectra for each solution have been obtained and analyzed. Furthermore, a transverse-sectional visualization of every sample has been created and examined by means of OCT.

Opis:
Optical low-coherence tomography is a measurement technique for non-contact and non-destructive investigation of materials inner structure. Nowadays, this method is highly applied in medical treatment especially in dermatology and ophthalmology. During our research we have developed an optical low-coherence tomography system with polarization state analysis for structure examination of a broad range of technical materials. In this paper we present our recent measurements including polarization sensitive analysis. Those measurements were taken for semitransparent and highly scattering materials like polymer layers and polymer optical retarders, anticorrosion protective coatings or abrasive paper. We proved that with the aid of developed polarization sensitive optical coherence tomography system it is possible to investigate birefringence principles of materials as well as to improve visualization contrast of cross-sectional images.

Opis:
Optical diagnostic methods of biological media are more and more willingly used in clinical practice - also instead of classical biopsy. Particularly, optical coherent tomography methods and mammography (permitting achieving three-dimensional imaging of a tissue) are attractive in comparison with classical diagnostic methods. The article presents the analysis methods of optical parameters of biological tissues developed allowing obtaining absolute values of these parameters. Thanks to modern image analysis methods - wavelet transforms - the optical diagnostic effectiveness was improved. The theoretical and practical results achieved were compared with results of commercially accessible methods implemented in OCT devices.

Opis:
Wet age-related macular degeneration (wet AMD) is a disease which requires regular diagnostic tests such as macular optical coherent tomography which is extremely important both in diagnosis and disease monitoring. With constant aging of the population, we are dealing with an increasing incidence rate of AMD, which makes it even more important to have a tool allowing for quick and precise analysis of anatomical changes in macular region, particularly in the current complicated epidemiological situation when diagnostic time should be used most efficiently to plan the follow-up treatment. Forum® software allows for the precise analysis of many tests performed in a single patient and combining it with treatment effectiveness assessment which substantially accelerates the diagnostics.
Wysiękowa postać zwyrodnienia plamki związanego z wiekiem to schorzenie, które wymaga regularnej diagnostyki okulistycznej, głównie w postaci okresowo wykonywanej optycznej koherentnej tomografii plamki. Rola tego badania jest niezmiernie ważna zarówno w procesie diagnostyki, jak i monitorowania. Jako że wraz ze starzeniem się populacji mamy do czynienia ze wzrostem zachorowalności na wysiękową postać zwyrodnienia plamki związanego z wiekiem, coraz bardziej istotna staje się potrzeba szybkiej i precyzyjnej analizy zmian anatomicznych obszaru plamkowego, tak aby w dodatkowo skomplikowanej sytuacji epidemiologicznej maksymalnie efektywnie wykorzystać czas przeznaczony na diagnostykę oraz zaplanować dalsze etapy leczenia. Dzięki oprogramowaniu o nazwie Forum® zyskujemy możliwość precyzyjnej analizy wielu badań wykonanych u danego pacjenta, łącznie z oceną skuteczności leczenia na przestrzeni czasu, co znacznie przyspiesza procesy diagnostyczne.

Opis:
Optical coherence tomography (OCT) imaging has become a useful tool in medical diagnosis over the past 25 years, because of its ability to visualize intracellular structures at high resolution. The main objective of this work is to add electronic feedback to the optical coherence tomography setup to increase its sensitivity. Noise added to the measured interferogram obscures some details of examined tissue layered structure. Adjusting signal power level in such a way to improve signal-to-noise ratio can help to enhance image quality. Electronic feedback is added to enhance system sensitivity. A logarithmic amplifier is included in the OCT setup to automatically adapt signal level. Moreover, the resolution of the optical spectrum analyzer is controlled according to the farthest layer detected in the A-scan. These techniques are tested showing an improvement in obtained image of a human nail.

Opis:
Purpose of this work is to introduce results of biological objects measurements with Optical Coherence Tomography system working with swept source laser (OFDI system). This specified source with spectrum centred around 1040 nm is dedicated to measure posterior segment of the eye. OCT with this wavelength is expected to be next generation for this sort of systems. Although commonly used 800 nm source enables imaging retina, deeper tissue layers are not available with this wavelength. Longer wavelengths in range of infrared spectrum (e.g. 1040 nm) are being weakly scattered which enables to go down to the choroid layer [1]. Examination this structure composed mostly from blood vessels might be very important for early diagnosis of eye diseases. In this paper system setup, swept source scheme and eye images would be introduced.

Opis:
Surface tension measurements and molecular dynamics (MD) simulations were used to explore the flotation foam properties and self-aggregation behaviors of dodecylamine (DDA)/octanol (OCT) mixtures formed with different mole ratios at the air/liquid interface. Based on the surface and thermodynamic parameters, the DDA/OCT mixtures exhibited greater interfacial activities and adsorption capacities than their individual components. The MD simulations showed that DDA and OCT were aggregated through hydrogen bonding, coulombic forces and hydrophobic association. OCT was inserted into the DDA adsorption layer, causing the alkyl chains of both DDA and OCT to extend from water to air at varying heights and angles. The addition of OCT improved the hydration of the amino groups and reduced the overall number of hydrogen bonds. The stability of the flotation foam decreased, and the high viscosity and difficult defoaming of the DDA flotation foam were significantly improved. When the DDA/OCT mole ratio was 2:1, the included angle formed between the alkyl chains and the interface was maximized, leading to enhanced compatibility among the alkyl chains, and the hydrogen bond energy was relatively large, which showed a strong synergistic effect. The MD simulation findings were consistent with the results obtained from the lepidolite flotation and surface tension experiments conducted in this study; our results could provide a theoretical foundation for the selection of superior mixed collectors and frothers.

Opis:
The nervous system's ability to receive light stimuli and its' processing in the brain in order to produce a visual impression is the definition of the sense of sight. The anatomical form of the sense organ of vision is comprised of the eyeball, the eye's protective apparatus, the eye's movement apparatus and the retinal nerve connections made to structures in the brain. The shape of the eye's lens, which gives the eye its refraction ability, depends on the voltage present in Zinn's ligaments that regulate the ciliary muscle. Sharpness of vision is produced by changing the shape of the lens, a reflexive adjustment. A domed lens causes stronger light inflexion and allows a sharp visual appearance of close objects. A flattening of the lens results in less light refraction and the seeing of more distant objects. The lens consists of a capsule, a cortex and a nucleus and it has two convex surfaces: the front and the rear. If we imagine the lens as a plum fruit, the capsule is its skin, the cortex is its flesh and the nucleus is its stone. Proper functioning of the lens is essential for accurate vision. Exact assessments of the eye's lens and the ability to monitor the status of associated diseases are extremely important. The lens may be tested using a slit lamp, but in any situation where an eye disease prevents this assessment of the lens this examination will obviously be inadequate. Thanks to today's imaging techniques, we can now assess the anatomical arrangement and condition of the lens, even in the eyes of those patients for whom the use of an imaging lens slit lamp is not possible [1, 2].

Opis:
Aim: If companies manage their inventory inefficiently, inventory costs can increase significantly due to shortages, overstocking, and risks. Inventory management is critical for company’s success which, in turn, impacts on countries’ development. This paper aims to investigate the efficiency of inventory control systems of companies from Brazil and Chile through Optimal Control Theory and Data Envelopment Analysis. Design/Research methods: Data was collected from Chilean and Brazilian companies covering different industries in which both countries are mostly dependent A new approach using OCT and DEA is applied for dealing with inventory, production, and demand in Dynamic DEA model to benchmark companies’ production-inventory systems. Conclusions/findings: The results show efficient companies among evaluated industries. Such companies are related mainly to Brazilian commerce and Chilean exports. Based on findings, it was possible to identify patterns and relationship among companies and its inventory management. Originality/value of the article: This paper fills a gap in studies including demand, production, and inventory in Dynamic DEA by using OCT to forewarn unrealistic results and observing companies’ behavior. Besides that, this approach is particularly useful for developing countries in this context, determining benchmarks for the most inefficient firms in each sector. Implications of the research: The results show (1) which companies should focus more on improving inventory management, (2) which companies should be used as benchmarks, and (3) it highlights the reasons of different performance of companies in each country. Limitations of the research: For future research, it is suggested including variables and analysis of social and environmental impacts.

Despite the improvement of diagnostic and therapeutic techniques age-related macular degeneration is still one of the main causes of central vision impairment. Throughout the years, the classification of subretinal neovascularization in the course of age-related macular degeneration has changed due to the advancement of diagnostic and therapeutic techniques. In 2020 an expert panel reached consensus on a new nomenclature for neovascularization in the course of age-related macular degeneration introducing the concept of macular neovascularization, which refers to each neovascularization in macula, regardless of the location.
Zwyrodnienie plamki związane z wiekiem (AMD, age-related macular degeneration), mimo postępu w diagnostyce i leczeniu tej choroby, stanowi jedną z najczęstszych przyczyn utraty widzenia centralnego. Na przestrzeni lat klasyfikacja neowaskularyzacji podsiatkówkowej w przebiegu AMD zmieniała się wraz z rozwojem technik diagnostycznych i terapeutycznych. W 2020 r. panel ekspertów opracował konsensus dotyczący nowego nazewnictwa neowaskularyzacji w przebiegu AMD, wprowadzając pojęcie neowaskularyzacji plamkowej, które dotyczy każdej neowaskularyzacji w plamce, niezależnie od jej lokalizacji.
