Abstract

Ultrasound imaging is one of the common methods in medical diagnostic systems. There are many artifacts in a two dimensional image. Three dimensional imaging can be used for better interpretation and perception of an image. Since 1969 many attempts have been made in this regards, and research continues all over the world. The main goal in our research was to create three - dimensional images using conventional 2-D ULTRASOUND systems.To obtain three dimensional data for construction of 3-D images, a conventional sonography with linear array transducer was used. The 2-D images of an aluminum cylinder, fiber glass sphere, human hand, sheep kidney, human kidney, and carotid were taken. Using a scanner with three degree of freedom, the images locations were determined. In one of three directions, the transducer translations movement was performed. Using a stepping motor the scanner movements were achieved. High level language programming 'C' were written to control the scanner. Each image slice was obtained with 1mm slice thickness step. Using appropriate image processing techniques such as filtering and interpolation, image reconstruction was performed from obtained 2-D images. These image processing were done using MATLAB software. After reconstruction images in other dimensions, the images were studied from two aspects. At the first step the size of reconstructed images compared with the main object. For one dimension of an object 12.5mm, average of images was 12.629 mm. There was not significant difference between them. In next step, images were compared with the main objects regard their appearances. For objects such as fiber glass sphere, aluminum cylinder, because of the artifacts, reconstructed images were not exactly like main objects. But for human hand, sheep kidney, and carotid , there was proper accommodation between images and main objects. For human kidney, the obtained images were not clear. In vitro, reconstruction of images for objects which are equal with the organs like sheep kidney and human hand was done. In vivo for carotid vessel there was accommodation between carotid and its images. For human kidney was not done.
