Systems, methods and apparatus for acquiring an image from within a body lumen are provided. Systems embodying features of the invention include an intracorporeal imaging component for acquiring imaging information, an image information recording component, and an image information playback component. Methods for acquiring image information from within a body lumen include steps of acquiring imaging information, storing image information, and playing back imaging information. Imaging information may be played back as acquired, or non-sequentially, or composite images may be formed by combining, filtering, enhancing, or subtracting images and the composite images displayed. Devices embodying features of the invention include optical imaging components such as an optical IGW, an optical imaging recording component, and an optical image playback component. The systems, methods and devices are suitable for use with angiopoplasty, stent delivery, and other intracorporeal clinical procedures.
A system for acquiring imaging information from within a body lumen, comprising an imaging information acquisition component comprising an imaging guidewire (IGW) configured to detect image information from within a body lumen by performing a rotational scan effective to acquire imaging information from a plurality of positions within said body lumen, an image information storage component configured to store image information in an electronically readable form, an image information playback component configured to read said stored image information and to output an electronic signal in accordance with said stored image information, and transmission elements effective to transfer image information between said imaging information acquisition component and said image information storage component and between said image information storage component and said image information playback component.
A method of acquiring, storing, and playing back imaging information acquired from within a body lumen, comprising the steps of:
A device for acquiring, storing and playing back imaging information acquired from within a body lumen, comprising an acquisition component, an addressable memory component, a playback component, and image information transmission elements operably connecting said components, said acquisition component being configured to record rotationally scanned image information in said addressable memory component in an electronically-readable form at an acquisition rate, and said playback component being configured to play back store imaging information at a playback rate, wherein said playback rate may differ from said acquisition rate.
