An ultrasound characterisation method of a medium comprising the steps of generating a series of incident ultrasound waves, measuring a canonical reflection matrix defined between the input emission base and an output reception base, determining a set of responses of the medium obtained from the canonical reflection matrix, at a plurality of frequencies and for several points in a region around a reference point, determination of a frequency correction law from the responses of the medium at the various points, the frequency correction law being adapted to the reference point and being determined at frequencies, determination of the corrected responses of the medium by applying the frequency correction law to the responses of the medium around the reference point and for the plurality of frequencies.

The present embodiments relate generally to medical care and more particularly to a new imaging modality referred to herein as electroacoustic tomography (EAT) that not only depicts electrical field energy distribution in real time, but also enables clear discrimination between IRE and RE zones in situ during the treatment. According to some aspects, EAT exploits the phenomenon that the amplitude of acoustic emission generated by an electric field is proportional to the electrical energy deposition in tissue. After detecting these acoustic waves with ultrasound transducers, an image of the electric field distribution can be reconstructed in real-time. This will allow real time monitoring the IRE and provides feedback control of the treatment. Some embodiments are directed to a novel EAT combined with ultrasound (EAT/US) guided IRE intervention that permits a) real time ultrasound image-guided needle placement, and b) intraoperational discrimination of IRE and RE zones during the treatment of cancer.

A TGC control system for an ultrasonic diagnostic imaging system has TGC controls which are constructed as a single elongated module with periodic enlarged regions spaced along the elongated module. The number of enlarged regions is equal to the number of TGC zones to be controlled. Touch sensors are located on opposite sides of each enlarged region and a user can touch one side of an enlarged region to increase the gain in a TGC zone, and touch the other side of the enlarged region to decrease the TGC gain in the zone. The amount of gain adjustment is determined by the height at which the user touches the enlarged region.
