Image Reconstruction in Ring Array Ultrasound Tomography by Means of Enhancing the Sinogram

Khusnul Ain, Deddy Kurniadi, Amoranto Trisnobudi, Oerip Santoso


The Ring Array Ultrasound Tomography is the system which has been used for breast cancer detection. The system is potentially developed due to unmovable mechanically, safe and obtainable high resolution image. The study means to reconstruct ring array ultrasound tomography by reposition and spline-interpolation data into parallel beam Sinogram. The study was conducted with numerical and experimental object by 16 and 32 transducer positions to obtain 31x31 pixels of images. Sinogram was repaired by an RMSD method and reconstructed by the SCFBP method. The results indicate that the methods of Sinogram enhancement can only improve the image of 0.02%. The study showed that 16 transducers had produced a blur image and been dissimilar to the object, but 32 transducers could generate a good image but it is still worse than parallel beam.
