Abstract: To improve the accuracy of particle image reconstruction, a new image reconstruction method, improved binary back projection algorithm using triangular-criteria (IBBPAT) for in-line ultrasound processing tomography (UPT), is presented. An ultrasonic transducer array consisting of eight transducers working as both transmitters and receivers and 16 ultrasonic transducers working only as receivers, is adopted in the simulation. The transducers that also function as transmitters emit fan-shaped ultrasonic waves. Based on multiphysics software (COMSOL Inc., Palo Alto, CA), signals scattering a cylindrical wave by different distribution of bubble particles are simulated. The results are entered in to IBBPAT for bubbles reconstruction and then the position and size of each bubble particle are accurately reconstructed. As indicated by the final results, spatial image error (SIE) of IBBPAT is clearly less than that of binary back projection algorithm (BBPA).
