Abstract: 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.

Abstract: The invention generally relates to intravascular ultrasound imaging and to systems and methods to improve line density and image quality. The invention provides an intravascular imaging system that uses a clock device to provide a set of trigger signals for each revolution of the imaging catheter and capture various patterns of scan lines for each set of trigger signals. The system can be operated to capture two scan lines of data for each trigger signal thereby doubling scan line density compared to existing systems. The clock device can be provided by hardware, such as a rotary encoder, that is configured to define a maximum number of trigger signals that the module can provide per rotation of the catheter.

Abstract: Methods, devices, and systems for providing seamless, co-planar intravascular ultrasound (IVUS) images are provided. In some embodiments, the methods include projecting a first A-scan line from a distal frame onto a reconstruction plane that extends perpendicular to an imaging axis, projecting a second A-scan line parallel to the first A-scan line from the proximal frame on the reconstruction plane; and determining a grayscale value of a point on the reconstruction plane by a weighted average of the first A-scan line and the second A-scan line.
