Abstract
A method for Fresnel zone imaging is provided. The method comprises identifying a plurality of constructive regions and a plurality of destructive regions in an energy transmitting device and converting the destructive regions to the constructive regions by using an apodization profile. The apodization profile comprises apodization values for each constructive region and destructive region and the apodization values comprise real numbers.
Claims22
A method for Fresnel zone imaging, the method comprising;
- identifying a plurality of constructive regions and a plurality of destructive regions in an energy transmitting device;
- converting the destructive regions to the constructive regions by using an apodization profile;
- wherein the apodization profile comprises apodization values for each constructive region and destructive region, wherein the apodization values comprise real numbers.
An ultrasound imaging system comprising:
- a transducer array comprising a plurality of transducer elements, wherein the array is configured to focus an ultrasound beam on a region of interest;
- wherein each transducer element comprises a plurality of constructive regions and a plurality of destructive regions,
- a processor configured to generate an apodization profile;
- wherein the apodization profile comprises apodization values for each transducer element, and wherein the apodization values comprise real numbers;
- and
- a control processor configured to apply bias voltages to each transducer element;
- wherein the bias voltages are derived using the apodization profile.
