A topic of interest related to titanium alloy Ti-6Al-4V implants is optional surface treatment. In many cases surface treatment is used for bioactivation of the implant and thereby improvement of its biocompatibility and osseointegration. An important factor of surface properties in the context of applying coatings is its roughness. This paper discusses the(More)
The measurement of the surface temperatures by infrared thermography is not frequently used in medicine despite of its safety, painlessness and invasiveness, good reproducibility and low running costs. Promising results have been achieved in nerve entrapment syndromes or neuropathies, although thermography has never represented as a real alternative to the(More)
The presented study deals with temperature distribution of healthy human bodies which were measured by infrared thermography. We used Infrared Imager with detector type 320×240 Focal Plane Array, Vanadium Oxide (VOx), Uncooled Microbolometer. A database of 240 thermograms from different position or locality of human body was created. The following(More)
Presented paper deals with infrared thermography (IRT) used for the diagnostics of Carpal Tunnel Syndrome (CTS). More studies on medical thermography in the relation with CTS diagnostics were published. Jesensek Papez B. et al. in 2008 and 2009 improved outcome with classification success rates near to or over 80% in dorsal segments of hand. The background(More)
Ti6Al4V samples have been prepared by Direct Metal Laser Sintering (DMLS) with varied laser power. Some of the samples were stress-relief annealed. The microstructure of materials was investigated using a light microscopy. Columnar grains of martensite dominate in as-made microstructure. Stress-relief annealing led to the white acicular phase growth in the(More)
Medical thermography is a powerful tool for the study of surface temperature of the human body. It is non-invasive, non-radiation, painless and non-contact imaging technique with numerous medical applications including musculoskeletal system, its disorders and injuries. Often it is useful to cross-reference the resulting thermograms with visual images of(More)
At the present time in many countries of the worlds preoperative planning of interventions for lumbar joint is realized with caliper, protractor, plastic templates and x-ray images. From these reasons the measurement is time consuming with many errors. Over the past few years, an increasing appreciation of the usefulness of digital technology has emerged(More)
Computed tomography scanners (or CT scanners) are very popular medical equipments for tens of years. Its invention initiated a revolution in diagnostic technology by allowing us to look inside a person and obtain a very clear anatomical image without violating the outer surface of his body, in other words, non-invasively [10]. Just few years ago this(More)
The study deals with thermographic (IRT) diagnosing in neuro-vascular diseases of the human hands such as the Carpal Tunnel Syndrome (CTS). It is considered to be an approach to screening thermal manifestations of the difference between the physiological temperature distribution in the skin of dorsal hands and pathophysiological temperature distribution in(More)
The need to increase the effectiveness of diagnostics and treatment of scoliosis through the design of a system for measuring pressure between an orthosis and the trunk of the subject originated on the basis of requirements of clinical orthopedic and prosthetic practice. Single-use thin pressure films were used for determining the optimal range of pressures(More)
