Abstract：In order to optimize the acoustic computer tomography (CT) reconstruction system for the 3D temperature field, the reasonable selection of sound path was performed with simulation research.Twenty sound transceivers were arranged around a cuboid measurement area.Four acoustic path selection modes were considered, all non-duplicated paths were retained, and the paths on the edges, sides and surfaces of the cuboid were removed.In addition, the relative error and root-mean-square error were used to evaluate the reconstruction quality of temperature field.The results show that the selection modes of sound path have an obvious effect on the reconstruction of temperature field.The errors and computation amount in the acoustic CT method for the reconstruction of temperature field can be reduced through the reasonable selection of sound path.
