Reconstruction of left ventricle motion based on USG 4D graphic data

I.

Original USG cardiac image – cross-sections of one of the frames

II.

Frame matching – the first phase of ventricle motion reconstruction

III.

Result of matching of two frames – deformation of the grid shows the relative cardiac motion

IV.

Reconstruction the left ventricle shape from an averaged and noise-filtered USG image - from the interactive marking (at the top) to the full reconstruction at the bottom

V.

Reconstruction of the full cycle of the left ventricle motion – the calculation grid can be seen in the centre; the ventricle images in different moments coloured by movement can be seen on the circumference

VI.

Tomographic images made legible by separation of organ surfaces (VisNow visual analysis system; Krzysztof Nowiński, Bartosz Borucki, Hubert Orlik-Grzesik)
