17. An ultrasound scanner, comprising:
- first and second arrays of transducer elements, at least one of the first and second arrays transmitting incident wave fields into an object, the incident wave fields propagating into the object and, at least, partially scattering, at least one of the first and second arrays measuring a transmission wave field transmitted, at least in part, through the object, the transmission wave field being defined, in part, by the incident wave field and the object;
at least one of the first and second arrays measuring a reflected wave field reflected from the object, the reflected wave field being defined, in part, by the incident wave field and the object; and
a processing module processing the reflected wave field to form a reflection data set and processing the transmission wave field to form a transmission data set.

Abstract
A transmission wave field imaging method, comprising the transmission of an incident wave field into an object, the incident wave field propagating into the object and, at least, partially scattering. Also includes the measuring of a wave field transmitted, at least in part, through an object to obtain a measured wave field, the measured wave field based, in part, on the incident wave field and the object. Additionally, the processing of the measured wave field utilizing a parabolic approximation reconstruction algorithm to generate an image data set representing at least one image of the object.
