Enhanced ultrasound imaging apparatus and associated methods of work flow are disclosed herein. In one embodiment, a method of ultrasound scanning includes receiving a first dataset representing ultrasonic scanning of a target anatomy of a patient in a two-dimensional mode and generating a two-dimensional ultrasound image of the scanned target anatomy based on the received first dataset. The method also includes accepting a definition of at least one of a sagittal plane, a transverse plane, and a coronal plane on the displayed two-dimensional ultrasound image. Thereafter, a second dataset representing ultrasonic scanning of the target anatomy in a three-dimensional mode is received and an ultrasound image at the coronal plane of the target anatomy is generated based on (1) the three-dimensional scanning and (2) the accepted definition of at least one of the sagittal plane, the transverse plane, and the coronal plane.

A membrane hydrophone for analyzing high frequency ultrasound transducers has a piezoelectric membrane with electrode patterns created on the surface of the membrane. In one embodiment, the electrode patterns are doubled on each side of the membrane except for an active area of the hydrophone. In one embodiment, the electrodes are formed by removing a conductive coating on the membrane with laser pulses. The laser is set to remove the conductive coating from the piezoelectric membrane from the same side of the membrane in order to accurately align the electrodes in the active area. In one embodiment, the active area of the hydrophone has an area in a range of 900-10,000 square microns.

An ultrasonic imaging system comprises a processing system and an ultrasound imaging probe that is configured to transmit ultrasound energy into a selected portion of a subject and to receive echoes therefrom and to transmit data signals representative thereof to the processing system. The system further comprises a blood pressure sensor that is configured to measure the blood pressure of the subject and to transmit data signals representative thereof to the processing system. The processing system can processes the received ultrasound data signals to generate an ultrasound image and the received blood pressure data signals to generate a blood pressure trace. The processing system can also display the ultrasound image and blood pressure trace in a display image in which portions of the ultrasound image are displayed in temporal synchrony with portions of the blood pressure trace.

Beam enhancement through sidelobe reduction and/or mainlobe sharpening is shown. Embodiments utilize dynamic resolution, improved dynamic resolution, and/or enhanced dynamic resolution techniques to synthesize beams, such as ultrasonic beams used in ultrasonic imaging, having desired attributes. Embodiments simultaneously form a first sample beam and a second or auxiliary sample beam for every sample to synthesize enhanced scan beams. According to a dynamic resolution techniques herein a new beam may be formed from the sum of the two sample beams. A synthesized dynamic resolution beam of embodiments has reduced sidelobes with relatively little or no spread of the mainlobe. An enhanced dynamic resolution beam sharpening function can be applied to provide a further enhanced beam, such as to further narrow the mainlobe.

Adjustment of operation of an ultrasound imaging system may be based at least in part on one or more characteristics represented in ultrasound return signals from two or more sample volumes. Adjustment may include adjusting a principal sample volume location or selecting a new principal sample volume. For example, a location of a principal sample volume may be adjusted or new principal sample volume selected so as to remain focused on an identified region of interest or to maintain the principal sample volume relative to some structure or reference. The principal sample volume may be maintained in the center or along a centerline of an artery or other structure, as the transducer array is moved along the artery or structure.
