Computer analysis of medical image data
Krajčír, Róbert ; Šmirg, Ondřej (referee) ; Uher, Václav (advisor)
This work deals with medical image analysis, using variety of statisic and numeric methods implemented in Eclipse and Rapidminer environments in Java programming language. Sets of images (slices), which are used here, are the results of magnetic resonance brain examination of several subejcts. Segments in this 3D image are analyzed and some local features are computed, based on which data sets for use in training algorythms are generated. The ability of successful identification of healthy or unhealthy tissues is then practically tested using available data.

Acoustic analysis of sentences complicated for articulation in patients with Parkinson's disease
Kiska, Tomáš ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
This work deals with a design of hypokinetic dysarthria analysis system. Hypokinetic dysarthria is a speech motor dysfunction that is present in approx. 90 % of patients with Parkinson’s disease. Next there is described Parkinson's disease and change of the speech signal by this disability. The following describes the symptoms, which are used for the diagnosis of Parkinson's disease (FCR, VSA, VAI, etc.). The work is mainly focused on parameterization techniques that can be used to diagnose or monitor this disease as well as estimate its progress. A protocol of dysarthric speech acquisition is described in this work too. In combination with acoustic analysis it can be used to estimate a grade of hypokinetic dysarthria in fields of faciokinesis, phonorespiration and phonetics (correlation with 3F test). Regarding the parameterization, new features based on method RASTA. The analysis is based on parametrization sentences complicated for articulation. Experimental dataset consists of 101 PD patients with different disease progress and 53 healthy controls. For classification with feature selection have selected method mRMR.

Pseudo-colour imaging of the monochromatic pictures
Boleček, Libor ; Drastich, Aleš (referee) ; Říčný, Václav (advisor)
Diploma thesis displaying black and white image in false color includes a study of methods and creation of computer software. The main function of the program is to convert the monochrome image into the pseudo colors. This procedure is achieved increasing the diagnostic yield of image. The program may find application in medical field. The pseudocoloring is used several different methods for obtaining the best results, combined with modifications increasing brightness scale image contrast images. The program is created in the programming environment of Visual Studio 2008 and written in C # programming language. Entry program is monochrome images in various formats (JPEG, BMP). The output of the program can be printed in a false-color image or stored image again in several different formats.

Diagnostics and Maintenance Design
Schindler, Marek ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
Failures of the roads are an integral part of the use and aging infrastructure. Before proposing their maintenance and repair is necessary to make the diagnosis of the road. Technical specifications of TP 82 and TP 87 describe the correct execution of diagnostic methods, their methods of evaluation and suggested repair of pavements. In the Bachelor's work I am making the diagnosis of asphalt, with the subsequent proposal for repairs on the road III/4301 in the village of Nechvalín. All measurements, evaluation, design, repair and photo documentation is included in this work.

Analysis of hip dysplasia occurrence by selected dog breeds
KOHOUTOVÁ, Lenka
In my thesis I deal with canine hip dysplasia. The paper consist of two parts. The first part summarizes all the information available about this disease. These include factors influencing the emergence of the disease, clinical signs, evaluation systems, diagnosis, conservative ang surgical treatment, prognosis and prevalence. The second part is methodological. There are summarized data about particular breeds of dogs that were obtained Mastiff, Auvergne Pointing Dog, Beauceron, Fila Brasileiro, Brittany, Cavalier King Charles Spaniel, Czechoslovakian Wolfdog, French Pointing Dog, Italian Pointing Dog, Italian Wirehaired Pointing Dog, Small Blue Gascony Hound, Blue Picardy Spaniel, Newfoundland, Portuguese Pointing Dog, St. Germain Pointing Dog, Tibetan Terrier and Golden Retriever. In the end I gave breeding recommendations regarding to reducing the incidence of high grade of canine hip dysplasia.

Analysis of health problems in the breed parrots of the genus Amazona
JEŘÁBEK, Zdeněk
In addition to several critically endangered species, parrots of the genus Amazon are now commonly kept in the breeding zoos (zoological gardens) and as breeding pets. In observance of certain rules it is possible these parrots from tropical areas of the New World breed well in our environment and climate. Even with what the most suitable conditions for breeding in captivity, these parrots can be affected by various health problems and diseases. This study aimed to gather the latest knowledge veterinary issues affecting the parrots of the genus Amazon and they are divided into sections according to the type of disease and occurring health problems. Index of bird diseases: Infectious diseases. Injuries and accidents. Environmental effects. Development and growth abnormalities. Cancer diseases. Other diseases. The list of these diseases concludes summary of the most common diseases. At the end of this work are listed diseases to which they have parrots the genus Amazon predisposing conditions.

Compensatory therapy in patients with hallux valgus
DUŠKOVÁ, Šárka
This bachelor thesis is focused on the most common issue of foot acquired deformities, hallux valgus. This condition is characterized by the valgus positioning of the hallux with metatarsophalangeal joint rotation, varus and prominence of the first metatarsal head. The etiology of hallux valgus is multifactorial although risk factors for the developt of valgoid position of halluxes are divided in hereditary factors, direct and indirect effects. Deformity is often associated with longitudinal and transverse flatfoot. Deformity causes considerable difficulties to the patients, particularly in the form of post-exercise pain, calluses and blisters. Developing deformities may likewise create hammer fingers on the other toes. Last but not least, deformity and its complication significantly limit the selection of appropriate footwear. The main objective of this bachelor thesis is to summarize the available information concerning risk factors in the development of hallux valgus, the contemporary approaches in physiotherapy for the treatment of this deformity as well as the aplication of complex therapies and its effectiveness evaluation. In modern kinesiology, hallux valgus is not regarded as a foot problem only as it is rather a complex movement disorder. Therapy was applied symptomatologically on all body, using a movement compensation reaction system. An appropriate therapy compilation for this issue is also included. In the theoretical part, the basic terminology regarding hallux valgus is explained, breaching the subjects of foot kinesiology, phylogenetic and ontogenetic development. It also describes diseases and deformites caused by intermetatarsal angle calcification. The largest part of this section is devoted to risk factors in the development of hallux valgus and its conservative therapy. Conservative therapy was based on the thorough obtention of anamnestic data and kinesiological analysis; the selection and application of physiotherapy procedures was determined by the present symptomatology. Therapy was carried out individually according to the current status, age and overall condition of the patients when seeking to correct muscle imbalance, posture, stereotype walking practice, education and regime measures. A quantitative research method was approached, performed by studying 3 patients? case reports with hallux valgus and who had not yet underwent surgery. Every case report contains anamnestic data, kinesiology analysis, description of therapy and long term draft planning for physiotherapy. The patients come from the Private Practice Olga Poláková in Jihlava. At the start of the study, the patients were acquainted with the process and aims of the therapy. Therapy results are evaluated in discussion and conclusion sections. All patients showed improvement in foot pain and overall foot kinesiology improvement. Experimental results demonstrate that the therapy was chosen accurately thereby accomplishing the aim of the present study. This bachelor thesis can be useful in raising awareness regarding the conservative treatment of hallux valgus and in the clinical practice of physiotherapy.
