| Abstract: | A new method of improving longitudinal and lateral resolution of B-mode ultrasonograph has been described in this paper, With longitudinal and lateral criterion being set up, every reflective wave is determined to be effective or uneffective when it is compared with both criterion. The result of model test is: longitudinal resolution 1mm and lateral resolution 2mm. |
