摘要： Ultrasound image data representative of three-dimensional volume segments of an image volume of interest is acquired in synchronism with corresponding cardiac cycles of a patient. The image data representative of the volume segments is combined to provide image data representative of a three-dimensional image of the image volume. The image data acquisition may be synchronized to a selected phase of the patient's cardiac cycle, so that the image represents the image volume at the selected phase. Image data for a three-dimensional volume segment may be acquired during each of the cardiac phases of a cardiac cycle.

摘要： This invention provides an ultrasonic transducer system which utilizes a reconfigurable delay line to perform a variety of processing functions. In particular, for a preferred embodiment, the delay line utilized to sum the outputs of transducer elements is reconfigurable to provide serial processing of image scan lines while providing parallel processing of Doppler color flow scan lines. More particularly, the echo signals generated in response to the packet of color flow lines utilized to generate color flow information are applied in a predetermined way to two separate portions of the delay line, the portions of the delay line having different delay profiles, the resulting outputs being focussed to slightly different points in the image and thus providing color flow packets for two separate points in response to the transmission of a single packet of color flow lines. This results in a substantial enhancement of the system frame rate.Other possible applications of the reconfigurable delay line in an ultrasonic scanning system are also discussed, and a packet serializer is disclosed which buffers, sequences, and preprocesses the received packet data.

摘要： The disclosed ultrasound imaging apparatus and method use a transducer array with a very large number of transducer elements or a transducer array with many more transducer elements than beamformer channels. The imaging apparatus includes a transmit array including a multiplicity of transducer elements allocated into several transmit sub-arrays, and a receive array including a multiplicity of transducer elements allocated into several receive sub-arrays. The apparatus also includes several intra-group transmit processors, connected to the transmit sub-arrays, constructed and arranged to generate a transmit acoustic beam directed into a region of interest, and several intra-group receive processors connected to the receive sub-arrays. Each intra-group receive processor is arranged to receive, from the transducer elements of the connected sub-array, transducer signals in response to echoes from the transmit acoustic beam. Each intra-group receive processor includes delay and summing elements constructed to delay and sum the received transducer signals. The apparatus also includes a receive beamformer including several processing channels connected to the intra-group receive processors, wherein each processing channel includes a beamformer delay constructed and arranged to synthesize receive beams from the echos by delaying signals received from the intra-group receive processor, and a beamformer summer (a summing junction) constructed and arranged to receive and sum signals from the processing channels. An image generator is constructed and arranged to form an image of the region of interest based on signals received from the receive beamformer. The apparatus is practical in size, cost and complexity and is sufficiently fast to provide two-dimensional or three-dimensional images of moving body organs.

摘要： An ultrasonic diagnostic imaging system and method are provided in which aberration corrections are computed by comparing harmonic and non-harmonic images to derive aberration correction estimates. In a preferred embodiment the harmonic image provides a reference image against which aberrations in the non-harmonic image are compared. A preferred acquisition technique is to transmit at a frequency f and receive at a frequency n*f to acquire the harmonic image and to transmit at a frequency n*f and receive at a frequency n*f to acquire the non-harmonic image. In a preferred embodiment the aberration correction estimates are produced by back-propagating the image data to find the aperture correction data for the two images.

摘要： A system and method of ultrasound quantification acquires acoustic image data from anatomic locations distributed in more than 2 dimensions, and uses a segmentation algorithm to provide real-time volume measurements. A 2D array is used to acquire two orthogonal (bi-plane) 2D images simultaneously. The images are segmented individually to determine the volume borders using any number of acoustic algorithms. The borders from the two bi-plane images are mathematically combined to give a volume measurement. A control processor controls the system to thereby obtain instant feedback of the segmented image data and enhance the volume measurements of the image. The system and method is extended to a number of simultaneous 2D images and to a full 3D volume acquisition.

摘要： A phased array ultrasound scanning apparatus includes a one-dimensional (1-D) array of ultrasound transducer elements having transmit and receive elements. The 1-D array is responsive to a transmitter configured to energize the transmit elements for generating a transmit acoustic beam directed into a region of interest. A receive beamformer, operatively connected to the 1-D array, synthesizes receive beams, in response to echoes of the transmit acoustic beam received from the region of interest. The receive beamformer includes analog random access memory (ARAM) delay elements configured to delay signals received from the receive elements and provide the delayed signals on an output of the receive beamformer as a beamformed RF output. The beamformed RF output is suitable for use in forming an image of the region of interest.

摘要： An AC biasing arrangement for a micro-machined ultrasonic transducer (MUT) is disclosed. The AC biasing arrangement allows the sensitivity of each MUT element in an array to be adjusted without collapsing the MUT membrane. The sensitivity of the MUT element can be adjusted by varying the frequency of the AC bias signal supplied to the MUT element. An alternative embodiment of the invention adds a second AC bias signal having a phase opposite the phase of the first AC bias signal. This arrangement provides a neutral bias signal, thereby removing the large amplitude bias signal from the MUT element.
