A breast scanning system scans a breast of a patient with transducer arrays that transmit and receive ultrasound signals in a bath containing a medium, such as a liquid. A table is disposable over the bath to receive the patient thereon, and has an aperture formed in the table and positionable over the bath to receive the breast of the patient pendent therethrough and into the bath. The table is linearly vertically displaceable with respect to the bath. The system includes a preconditioning tank to precondition the liquid prior to being introduced into the bath. The bath includes means for securing the breast within the bath.

Breast scanning system

An apparatus and method for rapid real time imaging with wavefield energy using a C.P.U. programmed to process data derived from wavefield energy that has been transmitted and scattered by an object so as to reconstruct a wavefield image of the object. Electronic signals are propagated and are transduced into wavefield energy waves which in turn are propagated toward the object. Detectors detect the wavefield energy waves scattered by the object. The detected wavefield energy waves are then electronically processed and input into a high-speed digital computer which may comprise a C.P.U. and/or a C.P.U. in combination with an array or parallel processor. Data is also prepared and input to the computer representing the incident field and the computer then reconstructs a high-quality image of the object having high spacial resolution and including actual properties of the object. The media in which the object is embedded may be fluid or solid, homogeneous, or layered (such as stratigraphic layering, or ocean velocity layers, or layering of composites in nondestructive imaging applications), or may consist of porous material (either sedimentary deposits or composites in nondestructive testing).
