A system for forming a homogenized illumination line which can be imaged as a low-speckle line is disclosed. The system includes a laser configured to emit a collimated laser beam; and an illumination-fan generator that includes one or more linear diffusers. The illumination-fan generator is arranged and configured to (i) receive the collimated laser beam, (ii) output a planar fan of diffused light, such that the planar fan emanates from a light line formed on the distal-most one of the one or more linear diffusers, and (iii) cause formation of an illumination line at an intersection of the planar fan and an object.

An acoustic data acquisition/playback system and method enable acquisition of acoustic data from an ultrasound imaging system and subsequent substantially real time playback of the acoustic data in the same system or a different system. Acoustic data is acquired at a particular data rate from a signal processing pipeline associated with the ultrasound imaging system during an image acquisition session wherein the acoustic data is produced by exposing a body to ultrasound signals. The acquired data is preferably acquired early in the pipeline so that it is completely raw (e.g., RF, IP, pre-beamformed, post-beamformed, pre-video, etc.), but it could be partially processed. Raw data or near raw data allows for greater flexibility in later signal processing. The acoustic data is stored during the session in a nonvolatile memory, which can optionally be removable. Next, at a time after the image acquisition session, the acoustic data is introduced into a signal processing system (the same ultrasound imaging system or a different signal processing system altogether) from the nonvolatile memory at least at the date rate that it was acquired, in order to produce a real time image for a reviewer that can be modified by the reviewer by further processing, if desired.
