“…The latter is particularly true for intraoperative imaging devices such as transesophageal (TEE) and intracardiac echocardiography (ICE) due to their small aperture size. 3 Having a wide 3-D field of view can be of clinical relevance for interventional guidance as well as for diagnostic purposes. For example, left-right heart interactions might more easily be studied, which could be of diagnostic value in pulmonary hypertensive patients or patients with tetralogy of Fallot.…”

“…These approaches have typically focused on compounding several acquisitions, which involves both registration [3][4][5][6] and fusion. [7][8][9][10] The former is performed to bring all recordings in a common coordinate system while the latter combines the excess of data in the overlapping area for optimal visualization.…”

“…This article is an extension of our previous report 20 in which the multiscale iterative registration method based on Farnebäck optic flow was introduced and its accuracy validated using a set of simulated ultrasound volumes 21 and estimated using an in vivo data set. The addition presented in this article consists of (1) proposing an automatic method for determining the number of levels and iterations in the multiscale iterative scheme, (2) validating the spatial registration accuracy quantitatively using in vivo recordings, (3) including temporal registration in the proposed frame work, and (4) validating the accuracy of the temporal registration quantitatively using in vivo recordings.…”

The use of three-dimensional (3-D) echocardiography is limited by signal dropouts and narrow field of view. Data compounding is proposed as a solution to overcome these limitations by combining multiple 3-D recordings to form a wide field of view. The first step of the solution requires registration between the recordings both in the spatial and temporal dimension for dynamic organs such as the heart. Accurate registration between the individual echo recordings is crucial for the quality of compounded volumes. A temporal registration method based on a piecewise one-dimensional cubic B-spline in combination with multiscale iterative Farnebäck optic flow method for spatial registration was described. The temporal registration method was validated on in vivo data sets with annotated timing of mitral valve opening. The spatial registration method was validated using in vivo data and compared to registration with Procrustes analysis using manual contouring as a benchmark. The spatial accuracy was assessed in terms of mean of absolute distance and Hausdorff distance between the left ventricular contours. The results showed that the temporal registration accuracy is in the range of half the time resolution of the echo recordings and the achieved spatial accuracy of the proposed method is comparable to manual registration.
