Phantoms for ultrasound system in ophthalmology
Fabík, Vojtěch ; Mézl, Martin (referee) ; Harabiš, Vratislav (advisor)
In our work we have studied the ultrasonic imaging systems and their use in ophthalmology, especially with the device Nidek 4000. We described ophthalmological examination methods. In addition, we are using the simulation program Field II. It simulated eye phantom and created his B-scan and biometry, where we compared the effects of different central frequency ultrasonic probes and different speeds of sound in the resulting values. We also created phantoms using agarose gel and materials of different properties. On phantoms, we studied the effect of the velocity of ultrasound in measurement results, effect of the concentration of the agarose gel to the velocity of sound. And we created phantoms simulating the human eye. Measurement protocol was created for use in teaching.

Determination of acoustic properties of brick body
Hladík, Lukáš ; Skotal, Zbyněk (referee) ; Sokolář, Radomír (advisor)
Bachelor thesis deals with the possibility of increasing the index of the air soundless the wall brick forms. The theoretical part summarizes the present knowledge in the field of acoustic properties of the ceramic shard and also the theory and methodology of the appraisal the index of the air soundless of building materials. Then there is the possibility of using ultrasound for indirect appraisal of the index the air soundless of a brick shard described both in the theoretical part in the form of a research of existing sources and in the practical part.
