The position and strength are converted to a target beam shape, and focus data to form the beam in the target beam shape are computed. The image is generated or the treatment is performed by using the computed focus data.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic imaging technique which realizes a contrast echo image with a high S/N ratio sufficient to perform a definite diagnosis based on the contrast echo image by imaging, by clearly distinguishing an echo component generated by being scattered by a micro bubble system contrast agent from a Tissue Harmonic component generated by a transmission pulse being nonlinearly propagated.

When N is an integer of ≥3, the contrast image is formed by using a transmission pulse wave using an envelope in common under the same wave transmission and reception focus condition, rotating the phase of the carrier wave by every 360°/N, performing N times wave transmission and reception, and obtaining an summation signal (d) by adding N time series reception echo signals (a), (b) and (c) obtained by the N times wave transmission and reception.

摘要： PROBLEM TO BE SOLVED: To achieve imaging in which all three characteristics, i.e., frame rate, spatial resolution, and contrast medium selectivity, are balanced in an ultrasonic contrast imaging method for extracting signals, specific to a contrast medium, and imaging. SOLUTION: An ultrasonic imaging apparatus includes a decoding section 13 that transmits/receives a first chirp signal, which increases in frequency with time, and a second chirp signal, which is obtained by inverting the first chirp signal on a time base, and that holds decode filters corresponding to coded lines when the chirp signal and the pulse signal are decomposed into the coded lines. The decode filters are used for reception echoes corresponding to two chirp signals. Outputs from the two decode filters are passed through a subtractor 14 and a difference between them is obtained, thereby enabling both contrast medium selectivity and spatial resolution.
