Bio-electromagnetic compatibility
Matulík, Martin ; Rozsívalová, Zdenka (referee) ; Matulík, Radomír (advisor)
Following work deals with problems of effects of electromagnetic radiation on living organisms. It goes into interactions of electromagnetic radiation with environment, effects on living organisms, physical units of biological tissues and sorting types of electromagnetic radiation to determine means of protection against adverse health reactions. It enlighten means of establishing sanitary restrictions, differences in legal aspects at Czech republic and worldwide, possible medical utilization, even principles of selected diagnostic and therapeutic techniques. It looks into shielding effects of common materials, ordinarily used for protection against ionizing radiation via findings of practical measurements. Series of radiofrequency measurements has been done with precise spectrum analyzers, which should reveal some basic problems of frequency bands, ordinarily used in current period.

Vertebra detection and identification in CT oncological data
Věžníková, Romana ; Harabiš, Vratislav (referee) ; Jakubíček, Roman (advisor)
Automated spine or vertebra detection and segmentation from CT images is a difficult task for several reasons. One of the reasons is unclear vertebra boundaries and indistinct boundaries between vertebra. Next reason is artifacts in images and high degree of anatomical complexity. This paper describes the design and implementation of vertebra detection and classification in CT images of cancer patients, which adds to the complexity because some of vertebrae are deformed. For the vertebra segmentation, the Otsu’s method is used. Vertebra detection is based on search of borders between individual vertebra in sagittal planes. Decision trees or the generalized Hough transform is applied for the identification whereas the vertebra searching is based on similarity between each vertebra model shape and planes of CT scans.
