Real-Time Four-dimensional Imaging of the Heart with Multi–Detector
Row CT
Movie 1. The preview window is shown.
All parameters can be changed interactively on the viewer. The
order of phases can be changed, and interesting areas can be focused
on.
Movies 2, 3. Four-dimensional volume rendering is shown.
All parameters can be changed interactively on the viewer. (Movie
2) The moving arteries and veins of a heart can be seen. (Movie
3) In the last frame, which is the optimal frame, the red arrow indicates a stenosis of
the left main segment of the left coronary artery. The blue arrows
indicate plaques in the left coronary artery.
Movies 4–6. Four-dimensional MPR views. The parameters
can be changed interactively at the viewer. (Movie 4) Axial
view of the heart shows the movement of walls and the defects,
which are old infarctions in the posterior wall and the ventricular septum.
(Movie 5) 4D MPR axial view of heart shows the movement
of walls, the infarction in the apical wall, and one thrombus in
the left ventricle and two in the right atrium.
(Movie 6) 4D MPR longitudinal view of heart shows the movement
of walls, the infarction in the apical wall, the mitral valve,
and the three thrombi.
Movie 7. Four-dimensional slab MIP. All parameters can
be changed interactively on the viewer. The last frame shows an
example of analysis.
Movies 8, 9. Synchronized real-time 4D imaging. All
parameters can be changed interactively on the viewer. The lines on the MPRs show the planes of the MPRs. Blue lines show the axial MPR plane, red lines show the sagittal MPR plane, and green lines show the coronal MPR plane. The light blue rectangles show the boundaries of the volume rendering image. (Movie
8) Synchronized multiple 4D views in 2 x
2 windows. Three 4D MPR views and one 4D volume-rendering view
are synchronized with the phase. Each crossing point of the lines on the 4D MPRs is at
the stenosis in the left main segment of the left coronary artery.
(Movie 9) Synchronized multiple 4D views in 4 x
4 windows. Three 4D MPR views, one navigator view, and four 4D
volume-rendering views are synchronized with the phase. Each crossing point of the lines on the 4D MPRs is at the stenosis of the left main segment of the left
coronary artery.
