摘要： Imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to removing artifacts caused by longitudinal motion of a sensor during imaging. In some embodiments, a medical sensing system includes a de-seaming engine operable to receive a first signal at a first point and second signal at a second point. The first and second points are offset from the pixel in the longitudinal direction. The de-seaming engine corrects for movement in the longitudinal direction by determining a weighted average of the first signal and the second signal. The engine determines a first probability based on the first signal and the weighted average and determines a second probability based on the second signal and the weighted average. The engine selects one of the first and second signal intensities as an intensity of the pixel based on the first and second probabilities.

摘要： Sold-state intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to flexible and efficient systems for focusing IVUS echo data received from transducers including polymer piezoelectric micro-machined ultrasound transducers (PMUTs). In one embodiment, an ultrasound processing system includes first and second aperture engines coupled to an engine controller, which provides aperture assignments to the first and second aperture engines. The aperture engines receive the assignment and a portion of A-line data, perform one or more focusing process on the received A-line data, and produce focused data in accordance with the aperture assignment. In some embodiments, once an aperture engine has produced focused data, the engine controller clears the aperture engine and assigns another aperture.

摘要： The invention generally relates to intravascular imaging system and particularly to processing in multimodal systems. The invention provides an imaging system that splits incoming image data into two signals and performs the same processing step on each of the split signals. The system can then send the two signals down two processing pathways. Methods include receiving an analog image signal, transmitting the received signal to a processing system, splitting the signal to produce a first image signal and a second image signal, and performing a processing operation on the first image signal and the second image signal. The first and second signal include substantially the same information as one another.
