Methods and system for characterizing an object
First Claim
1. A system for determining at least one characteristic of at least one anatomical structure, comprising:
- a first arrangement configured to forward at least one electromagnetic radiation having a time-varying intensity to the at least one anatomical structure and a further anatomical structure;
a detector second arrangement configured to detect at least one acoustic signal provided from each of the at least one anatomical structure and the further anatomical structure in response to the at least one electromagnetic radiation impacting the structures; and
a processing hardware third arrangement configured to (i) obtain calibration data from the acoustic signal from the further anatomical structure, based on at least one property of thereof; and
(ii) determine the at least one characteristic of the at least one anatomical structure using the calibration data and the acoustic signal from the at least one anatomical structure;
wherein the at least one anatomical structure includes at least one of a pulmonary artery or a vein, and the further anatomical structure includes at least one of an aorta or an artery.

Abstract
Exemplary system, method and computer accessible medium are provided for determining at least one characteristic of a target object located behind or within a medium. For example, it is possible to identify a reference object that is located behind or within the medium. The target object and the reference object can be irradiated via a surface of the medium using at least one electromagnetic wave. At least one acoustic signal provided from an irradiated tissue volume that is responsive to the electromagnetic wave(s) can be measured. Calibration information can be obtained from the acoustic signal measured from the reference object based on at least one known property of the reference object. Then, the characteristic(s) of the target object can be determined based on the calibration information and the acoustic signal from the target object.

11. A non-transitory computer-accessible medium which includes computer executable instructions for determining at least one characteristic of a target object located behind or within a medium, wherein, when a hardware processing arrangement executes the instructions, the processing arrangement is configured to execute procedures comprising:
-
identifying a reference object that is located behind or within the medium; causing an irradiation on the target object and the reference object via a surface of the medium using at least one electromagnetic wave; measuring at least one acoustic signal provided from an irradiated tissue volume that is responsive to the at least one electromagnetic wave; obtaining a calibration information from the acoustic signal measured from the reference object on at least one known property of the reference object; and determining the at least one characteristic of the target object based on the calibration information and the acoustic signal from the target object; wherein the target object includes at least one of a pulmonary artery or a vein, and the reference object includes at least one of an aorta or an artery. - View Dependent Claims (12, 13, 14, 15, 16, 17)
