摘要： 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.

摘要： This invention describes a method for increasing the speed of the parabolic marching method by about a factor of 256. Firstly, to form true 3-D images or 3-D assembled from 2-D slices. Secondly, the frequency of operation can be increased to 5 MHz to match the operating frequency of reflection tomography. This allow the improved imaging of speed of sound which in turn is used to correct errors in focusing delays in reflection tomography imaging. This allows reflection tomography to reach or closely approach its theoretical spatial resolution of ½ to ¾ wave lengths. A third benefit of increasing the operating frequency of inverse scattering to 5 MHz is the improved out of topographic plane spatial resolution. This improves the ability to detect small lesions. It also allow the use of small transducers and narrower beams so that slices can be made closer to the chest wall.

摘要： A method for increasing the speed of the parabolic marching method by about a factor of 256. This increase in speed can be used to accomplish a number of important objectives. Firstly, the speed can be used to collect data to form true 3-D images or 3-D assembled from 2-D slices. Speed allows larger images to be made. Secondly, the frequency of operation can be increased to 5 MHz to match the operating frequency of reflection tomography. This allow the improved imaging of speed of sound which in turn is used to correct errors in focusing delays in reflection tomography imaging. This allows reflection tomography to reach or closely approach its theoretical spatial resolution of ½ to ¾ wave lengths.

摘要： Methods for imaging the internal structures of an object using an acoustic wave field are provided. In one aspect, for example, a method of imaging internals of a physical object using acoustic waves may include transmitting an acoustic wave field toward the object, receiving a resultant acoustic wave field with a receiver, where the resultant acoustic wave field is in response to the transmitted acoustic wave field reflected from or transmitted through the object, and determining a predicted resultant acoustic wave field derived from a model of the object. The method may also include determining a residual between the predicted resultant acoustic wave field and the resultant acoustic wave field, and back propagating the residual to determine corrections to the model of the object. In another aspect, the above recited steps may be further iterated to successively refine the model of the object over a number of iterations until a predefined condition is reached.
