摘要： An intravascular ultrasound imaging system comprises a catheter having an elongated body having a distal end and an imaging core arranged to be inserted into the elongated body. The imaging core is arranged to transmit ultrasonic energy pulses and to receive reflected ultrasonic energy pulses. The system further includes an imaging engine coupled to the imaging core and arranged to provide the imaging core with energy pulses to cause the imaging core to transmit the ultrasonic energy pulses. The energy pulses are arranged in repeated sequences and the energy pulses of each sequence have varying characteristics. The reflected pulses may be processed to provide a composite image of images resulting from each different characteristic.

摘要： Systems and methods for image processing based on ultrasound data. The system may include an IVUS catheter configured to collect data vectors including ultrasound data and an imaging engine configured to process the ultrasound data of the data vectors. The imaging engine may receive the data vectors and divide the data vectors into different sets. The ultrasound data of each respective set may be averaged and then an envelope of each set may be detected. The envelopes of each set may then be averaged to generate an enhanced data vector which may be used to generate an image.

摘要翻译： 基于超声数据的图像处理系统和方法。 该系统可以包括IVUS导管，配置成收集包括超声数据的数据矢量和配置成处理数据矢量的超声数据的成像引擎。 成像引擎可以接收数据向量并将数据向量划分成不同的集合。 可以对每个相应组的超声数据进行平均，然后可以检测每组的包络。 然后可以对每个集合的包络进行平均以产生可用于生成图像的增强数据向量。
