“…[7][8][9] However, C3DR may not be feasible for routine clinical practice, because 3D equipment may not be widely available and the 3D process is time-consuming. A simplified 3D reconstruction (S3DR) on the basis of 3 standard apical views may be more practical because the reconstruction process could be achieved from routine echocardiographic imaging without the need for 3D equipment.…”

“…Recent refinements in transducer localization using spark-gap techniques15 and mechanical arms19 have been particularly encouraging as crucial steps in three-dimensional reconstruction. A number of algorithms have recently been developed for this purpose.15 16,18, 2 These developing applications might be especially useful in patients with diseases that alter ventricular shape and function regionally, where the utility of models requiring major geometric assumptions would be limited.…”

SUMMARY The accuracy of two-dimensional echocardiographic left ventricular volume measurement in an isolated heart preparation was tested using Simpson's reconstruction of progressively fewer short-axis cross sections of known location. Echocardiographic images from five ejecting hearts submerged in a special tank were obtained under conditions designed for maximal accuracy of echocardiographic volume assessment. Echocardiographic determinations of 52 volumes at various times throughout the cardiac cycle were compared, by least-squares linear regression, with simultaneous direct-volume measurements by volumetric chamber (range 9.4-44.8 ml). Echocardiographic and direct measurements correlated well for all numbers of cross sections from 1-19 (r = 0.84-0.97); however, variability of direct volume predicted from a given echocardiographic measurement increased nonlinearly as the number of cross sections per heart decreased, and was especially large when three or fewer cross sections were used (SEE = 4.6-7.1 ml). We previously used isolated, ejecting dog hearts to compare directly measured ventricular volume (without reliance on geometric assumptions) with echocardiographic volume obtained by reconstructing multiple cross-sectional images obtained at 3-mm intervals along the vertical axis of the heart.'0 Comparison of simultaneous data obtained throughout the cardiac cycle revealed not only a high correlation of echo to direct volume, but also a high predictive value of direct volume from any echocardiographic determination owing to low variability (r = 0.972, SEE = 2.93 ml, direct volume range 9.4-54.7 ml). These measurements were obtained under highly controlled conditions and it was not expected that the accuracy of echocardiographic volume determination could be matched in clinical use or in research applications in intact animals. At the very least, one could not obtain the large number of slices used in that study, and we did not assess the accuracy of volume changes with decreasing numbers of slices.Using the same preparation in the present study, but analyzing the data using progressively fewer slices, we found that at least four cross-sectional images of known location are required to predict ventricular volume without significant loss in accuracy.

“…To reconstruct a 3D image from images of a lesser dimension, the location and orientation of the imaging primitives must be known. Coordinate values are explicitly tracked either acoustically 2,16,27 , mechanically 9,10,14,25,30,34,37 , or optically 26 . In other systems, a human or a machine makes scans at predetermined locations and/or orientations 4,11,15,17,23,28,39 .…”
