J. Roelandt et al., PRECORDIAL 3-DIMENSIONAL ECHOCARDIOGRAPHY WITH A ROTATIONAL IMAGING PROBE - METHODS AND INITIAL CLINICAL-EXPERIENCE, Echocardiography, 12(3), 1995, pp. 243-252
We report our initial experience with a precordial hand-held transduce
r assembly allowing computer controlled acquisition of cardiac images
for dynamic three-dimensional tissue reconstruction in adult patients.
A commercially available transducer and imaging system were used and
its video output interfaced with the three-dimensional reconstruction,
unit. Fbr this feasibility study, 20 patients in sinus rhythm and wit
h good image quality were examined. The dynamic motion of the valves a
nd ventricles was visualized in three-dimensional formats as well as r
elationships of complex pathology. Although the acquisition time in pa
tients in sinus rhythm is relatively short, the reconstruction time is
still too long and requires an experienced and dedicated operator. Ho
wever, with further developments in computer technology dynamic three-
dimensional echocardiography will undoubtedly become an, integral if n
ot the principal part of our routine echocardiographic examination in
the future.
