This elaboration presents the method of virtual positioning of the construction of an endoprosthesis of hip joint in a patient’s pelvis and femoral bone, reconstructed on the basis of imaging obtained from computer tomography. It is based on the matching of an implant to individual anatomical-biomechanical conditions. The method is established on the following procedures: diagnostic, spatial modeling, virtual measuring and targeted biometrological application for the model of bone structures. The final effect of the completed procedures is selection and optimal positioning of the endoprosthesis of hip joint before a planned medical intervention. The determined geometrical parameters of bone structures and settled positioning of the endoprosthesis can create data for the system of computer navigation.

Early fetal cardiac scan (EFCS) is becoming an increasingly common element of the first trimester ultrasound screening carried out at 11–14 gestational weeks. It offers the first possibility to detect congenital heart defects (CHD) or, in ambiguous cases, to identify those pregnancies where a more detailed cardiac scan would be required later in pregnancy. The size of the fetal heart at the end of the first trimester and the associated relatively low image resolution make it impossible to capture all cardiac data to inform the ultimate picture. However, even at this stage, cues of anatomical and functional abnormalities can be picked up, which suggest not only a CHD, but also a likelihood of cardiovascular symptoms typical of genetic disorders. EFCS should focus on cardiac position, atrioventricular (AV) connections, AV valve function, initial assessment of ventriculo-arterial (VA) connections and the presence of red flag signs in the three vessel and trachea view (3VTV). Proper use of color Doppler mapping makes it possible to overcome the low resolution of B-mode to a certain extent. Here we present our long-term experience in EFCS.
