Attorney, Agent or FirmInternational ClassA61B 008/00AbstractUltrasound data is generated by a receive beamformer. Ultrasound image processing is applied to the ultrasound data for presentation of an image. Various ones of the ultrasound image processing steps may be reversed. For example, persistence processing may be reversed in order to obtain ultrasound data associated with data prior to persistence processing. This recovered data may be used to generate an image or for application of a different amount of persistence. Other processes that may be reversed to recover ultrasound data include focal and depth gain compensation, dynamic range compression, intensity or color mapping, and various filtering, such as persistence or spatial filtering.Field of SearchUltrasonicHaving B-scan and Doppler Tissue attenuation or impedance measurement or compensation Anatomic image produced by reflective scanning With mechanical and electronic scanning Mechanical scanning Hand-held unit Electronic array scanning Blood flow studies Pulse Doppler With volumetric measurement CW Doppler Contrast enhancement Doppler effect (e.g., fetal HR monitoring) | |
