This work presents a system for the reconstruction of cross-sections w
ith arbitrary orientations derived from three-dimensional (3D) echogra
phic scanners. The interest for this powerful diagnostic tool has prom
pted us to develop a low-cost processing board that inserts easily int
o a stand-alone echograph. The proposed system is able to reconstruct
high-resolution cross-sections at one frame per second with a time lag
of about 60 s due the 3D acquisition process. The board, based on thr
ee pipelined DSP devices, has been designed to process volumetric data
collected with a commercial echograph by means a rotating probe synch
ronized with the ECG signal. The resolution of the reconstruction algo
rithm implemented on the processing unit has been evaluated both with
synthetic 3D data and with experimental data from a phantom.
