摘要： Pulse-echo imaging systems and methods are provided, including a transmit code sequencer and a pulse generation circuit, The transmit code sequencer is configured to input a transmit code sequence to the pulse generation circuit. A transducer is configured to receive electrical signals provided as pulses using coded excitation according to the transmit code sequence, and to transduce the electrical signals to pulses of energy other than electrical signals. The transducer is further configured to receive echoes of the pulses of energy other than electrical signals and convert the echoes to received electrical signals generate using coded excitation. A receive circuit is configured to receive the received electrical signals generate using coded excitation, perform analog sampling of the received electrical signals generate using coded excitation, and provide a weighted, summed digital signal by processing the analog samples. At least one example of a pulse imaging system described is configured for ultrasonic pulse-echoes. At least one example of a pulse imaging system described is a medical diagnostic imaging system.

摘要： A medical imaging apparatus, such as including a processor circuit, can be used to construct a first image of a plane parallel to the surface of an ultrasonic imaging transducer, the plane corresponding to a locus at a specified depth within a first region of tissue. The apparatus can obtain information about a location of a vessel in the first image, then obtain, from a second region of tissue, imaging information corresponding to loci in planes parallel to the surface of the transducer, the planes at depths automatically determined at least in part using the obtained information about the location of the vessel in the first image. In an example, the apparatus can automatically determine an adjusted depth corresponding to the location of the vessel in the second region, and construct a second image of a plane corresponding to the adjusted depth within the tissue.
