3-D ultrasound image slice acquirement using non-calibration

The objective of this article developed a method by using a set of simple instruments to visualize three-dimensional (3-D) ultrasound image combining 2-D DCT to remove the sparkle noise. In this paper we only use an ultrasound transducer, a video signal collector and a computer to visualize 3-D US imaging. Presented freehand three-dimensional (3-D) ultrasound need use position information to reconstruct the 3-D shape of the segmented object, but it also limits the probe's moving, such as speed. Because the object inside the body is alive, the accurate position information can't improve the reconstruct result. To solve the problems, the approach presented by us specifies some simple action to reconstruct the 3-D ultrasound data structure without sparkle noise.
