At the present time, the usage of ultrasound diagnostic equipmenthas become an inseparable part of diagnosis for a number of medicalinvestigations. Several scientific studies published in the last yearsshowed that when applying a diagnostic ultrasound system on animals itis possible to create negative changes in tissues. New ultrasoundtechnologies and higher output acoustic powers have brought a possiblerisk connected to the usage of ultrasound in diagnostics. The knowledgeof risk level and exploration of limiting factors is an important pointfor the assessment of marginal ultrasound exposure values of medicalinvestigation during pregnancy, especially in the first trimester. Thecontribution presents a MATLABZ application for modeling of tissueheating in human embryos at the developmental age of seven and eightweeks. Recent calculations of US fields, which are generated by severaltypes of various unfocused single transducers (rectangular, circular,and annular), represent maximum temperature elevation of 0.4 °C inembryonic model tissues for the exposure of 1 min. The models ofembryonic tissue heating provide comparative studies of possiblebio-effect with the purpose to explore limiting factors of ultrasoundexposure. |
