“…A unifying theory that relates Synthetic Aperture (or Focusing) Imaging to back-projection reconstruction methods has been developed by several authors [37] - [39]. This unifying theory makes it possible to analyze active imaging systems in terms of ellipsoidal analysis (i.e.…”

“…This unifying theory makes it possible to analyze active imaging systems in terms of ellipsoidal analysis (i.e. projections and back-projections on ellipsoidal surfaces), and provides direct insights into the predictable benefits of ellipsoidal backprojection tomography in comparison with conventional echography [39]. The EBP technique has the advantage of offering a high resolution power and is easy to implement [5] [8].…”

“…This includes the improvement of the resolution and image contrast capabilities which are dependant on several system parameters. A similar imaging system using the ellipsoidal backprojection approach in conjunction with circular or spherical apertures has been theoretically analyzed by Norton and Linzer (80s) and Anderson (90s) [2], [3], [5]. Anderson analyzed the 3D PSF of point scatterers that were in front of a circular sensor plane.…”

At Forschungszentrum Karlsruhe a 3D ultrasound computer tomograph (USCT) is currently under construction aimed at early breast cancer diagnosis. Ellipsoidal backprojection is applied to reconstruct 3D images. As USCT is a system used for imaging, there is a profound interest in analyzing the image resolution and image quality of this system, especially with respect to its system parameters such as number of the sensors, the geometry of the aperture, applied signal processing, etc. In this paper the results of first assessments of the resolution are presented. The resolution is evaluated in terms of the 2D full width at half maximum (2D FWHM) of the system's 3D point spread function (PSF). Slice images of 3D PSFs have been calculated to assess the spatial variability of the PSF within the current setup of the system. However, calculating these results is very time-consuming, thus an approximative approach for the analysis of the 3D PSF in XY and Z has been developed. This approach allows the analysis of the PSF while changing a variety of system parameters in real time. The long term goal of this project is the optimization of the system parameters with respect to the image quality.• Distribution of the angles of the contributing ellipsoids through the point scatterer. This depends on the position, orientation and number of the used SRCs.
