A 3D ultrasonic diagnostic imaging system produces 3D display images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. In a preferred embodiment the determination of motion and the consequent decision to use interpolated or interleaved data for display is determined on a pixel-by-pixel basis.

An ultrasound diagnostic apparatus that transmits an ultrasound beam using an ultrasound probe including transducers and generates acoustic line signal subframe data, includes: a transmitter that causes transmission transducer arrays to transmit the ultrasound beam; a receiver that generates a reception signal sequence; and a delay-and-sum part that performs delay-and-sum operation, wherein the receiver includes part receivers, the delay-and-sum part includes: part delay-and-sum parts that perform delay-and-sum to generate an acoustic line signal so as to generate acoustic line signal partial subframe data; part folding parts that extract an acoustic line signal sequence and arrange the acoustic line signals to generate acoustic line signal partial subframe folded data; a main summing part that sums the acoustic line signal partial subframe folded data to generate acoustic line signal subframe folded data; and a re-sequence part that re-sequences the acoustic line signals to generate the acoustic line signal subframe data.

An ultrasound system which is capable of biplane imaging is able to display, store and export independent image frames of only the reference image or only the variable orientation image, or the standard display of both images. The system is also able to sweep through a range of image plane orientations and automatically acquire an image in each orientation over the range of plane orientations. The system is preferably operable in the biplane tilt mode, the biplane rotate mode, or the biplane elevation tilt mode.

A synchronization method is suitable between a first electronic apparatus and a second electronic apparatus. The synchronization method include following steps. A first interrupt signal is generated to trigger a first timer on the first electronic apparatus. A radio frequency packet is transmitted from the first electronic apparatus to the second electronic apparatus. In response to that the radio frequency packet is received by the second electronic apparatus, a second interrupt signal is generated to trigger a second timer on the second electronic apparatus. The second timer is synchronized with the first timer or a timestamp of the first timer is estimated according to the second interrupt signal and the radio frequency packet.

Techniques for mapping behavior of a heart include acquiring a series of two or more images of the heart. The series of images is taken at one or more pixel locations, each pixel location corresponding to a region of the heart. Image data corresponding to the pixel locations can be obtained, and a periodicity of the image data measured for each of the pixel locations over the series of images. The periodicity corresponds to an electromechanical signal of the heart in the region corresponding to the measured one or more pixel locations.
