Problems solved by technology

Decreasing the acquisition frame rate increases the sampling time of the acquired frames and results in a lower temporal resolution image, which increases the risk that the operator will miss the presence of an in-vessel or implanted intravascular device (eg, a stent) if an automatic retraction is being performed to interrogate the vessel. the possibility of defects

Embodiment Construction

[0025] The present invention generally relates to systems and methods for generating intravascular images from two different types of data acquired from intravascular ultrasound (IVUS) devices. IVUS imaging is widely used in interventional cardiology as a diagnostic tool for evaluating diseased blood vessels (eg, arteries) in the human body, to determine the need for treatment, guide intervention, and / or assess its effectiveness. An IVUS device including one or more ultrasound transducers is introduced into the blood vessel and directed to the area being imaged. The transducer emits and then receives backscattered ultrasound energy in order to create an image of the vessel of interest. Ultrasonic waves are partially reflected by discontinuities arising from tissue structures (such as various layers of blood vessel walls), red blood cells, and other features of interest. Echoes from the reflected waves are received by the transducer and passed on to the IVUS imaging system. T...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to U.S. Nonprovisional Patent Application 14 / 257,496, filed April 21, 2014, which is a continuation-in-part of U.S. Patent Application Serial No. 14 / 037,683, filed September 26, 2013, and is therefore The entire contents of each of these are incorporated herein by reference. technical field [0003] The present invention generally relates to systems and methods for generating intravascular images. Background technique [0004] Intravascular ultrasound (IVUS) is an important interventional diagnostic modality for imaging atherosclerosis and other vascular diseases and defects. During the procedure, an IVUS catheter is threaded into a blood vessel over a guide wire, and ultrasound echoes are used to acquire images of the atherosclerotic plaque and surrounding area. [0005] There are two types of IVUS catheters commonly used, mechanical / rotary IVUS catheters and solid-state cathe...
