An ultrasonic diagnostic apparatus by which highly quantitative IMT measurement with little variations depending on examiners can be performed. In a tomographic method using the device, the distance between the object and the multi-pinhole collimator is selected to be smaller than the distance between the multi-pinhole collimator and the surface of the detector. The transport system contains a plurality of intrabay transport subsystems, an interbay transport subsystem, a plurality of stockers, and at least one linking subsystem. The present invention also discloses different techniques that reduce superfluous edges to further optimize the support mesh. Moreover, mounting grooves for receiving removable lenses are set on the main body of the eyeglass frame and the auxiliary eyeglass frame respectively.
