20100174190 | SYSTEM AND METHOD FOR EQUALIZING RECEIVED INTRAVASCULAR ULTRASOUND ECHO SIGNALS - A system and method are disclosed for providing an equalized ultrasound echo signal for the rendering intravascular images. The system includes an ultrasound catheter including an ultrasound transducer probe. An intravascular ultrasound console receives an ultrasound echo signal corresponding to reflections of an ultrasound signal by backscatterers. An ultrasound echo signal time-gain compensation equalizer compensates the ultrasound echo signal according to sub-bands within a frequency response spectrum of the ultrasound echo signal. After applying selective amplifier gains on the sub-bands, the sub-band signals are combined to create an equalized ultrasound echo signal. | 07-08-2010 |

20140056099 | System and Method for Focusing Ultrasound Image Data - 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. | 02-27-2014 |

The determining may be further based on at least one of a previous mode selection, a user preference, an operative course of a medical procedure, patient information, the first set of medical sensing data, a second set of medical sensing data, a status indicator, and a sensing device identifier. | 06-26-2014 |
20140180105 | SYSTEM AND METHOD FOR MULTIPATH PROCESSING OF IMAGE SIGNALS - 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. | 06-26-2014 |
20140180107 | ULTRASOUND IMAGING WITH VARIABLE LINE DENSITY - 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. | 06-26-2014 |
20150086098 | SYSTEMS AND METHODS FOR PRODUCING INTRAVASCULAR IMAGES - The invention generally relates to systems and methods for producing composite intravascular images of multiple data types. In certain embodiments, systems and methods of the invention involve causing transducers of an intravascular ultrasound device to generate a plurality of different types of data, each type of data being based on a different manner of operation of the transducers. The manner of operation of the transducers is adjusted for one of the types of data to thereby cause the transducers to generate modified data for the one type of data. The modified data is received and an intravascular image is displayed that includes the modified data. | 03-26-2015 |
20150087986 | SYSTEMS AND METHODS FOR PRODUCING INTRAVASCULAR IMAGES - The invention generally relates to systems and methods for producing intravascular images. In certain embodiments, systems and methods of the invention involve causing transducers of an intravascular ultrasound device to generate a plurality of different types of data, each type of data being based on a different manner of operation of the transducers. The systems and methods of the invention additionally involve adjusting the manner of operation of the transducers for one of the types of data to thereby adjust an acquisition frame rate of the one type of data to an adjusted acquisition frame rate. The one type of data at the adjusted acquisition frame rate is then received and an intravascular image that includes the one type of data at the adjusted acquisition frame rate is displayed. | 03-26-2015 |
