摘要：Three-dimensional reconstruction from a set of a two-dimensional ultrasound image isuseful for visualizing anatomy structures of an internal organ. This paper presents a mechanicallinear scanning device for a three-dimensional ultrasound imaging system to acquire sequencesof two-dimensional ultrasound image along with its position and orientation in three-dimensionalspace. The device included a linear sliding track driven by a stepper motor with a dedicatedhousing of a probe, a water tank with an object holder inside, and software installed on a standardcomputer. A mechanical sliding track enabled the two-dimensional conventional ultrasoundprobe moved in a regular linear manner. The mechanical linear scanning allowed fixed andpredefined translation steps in z-axis direction such that rotation error could be avoided. Inaddition, mathematical formulations were presented to relocate every pixel’s location of theultrasound image to the reconstruction volume in three-dimensional space. In the experiments,the device’s installation in a real environment was demonstrated, and the translation motion inspace was investigated. Evaluation of the scanning results using the proposed device wasperformed using a bone as a phantom. The experimental result showed that the proposed deviceproduced high quality scanning results and created high quality bone surface. Thus, it can beexpected would be useful to the three-dimension reconstruction applications.
