Device and method for displaying ultrasound images of a vessel
First Claim
1. A device for displaying a vessel (2), comprising a) a memory (10) in which a sequence of intravascular ultrasound images (I) is stored, the ultrasound images being indexed by the respective locations (x) of their recording in the vessel (2), b) a data input for information (A) which describes a current location in the vessel (2), c) a display unit (12) for displaying images (I1, I2, I3, At) of the vessel (2), wherein the device is designed to select from the memory (10) at least one ultrasound image (I2) corresponding to the current location in the vessel (2) and to display it on the display unit (12).

Abstract
The invention relates to a device and a method for displaying a vessel (2) with the aid of intravascular ultrasound images (1). A sequence of intravascular ultrasound images (I(E,x)) is generated by means of a probe (5) and stored in a memory (10) in a manner indexed by the associated location (x) where they were generated and also the associated heartbeat phase (E) and/or breathing phase. During a subsequent medical intervention, those ultrasound images (I1,12,13) which best correspond to the heartbeat phase of a current fluoroscopic image (At) or belong to the current stopping location of a catheter (13) can be selected from the memory (10) and displayed on a monitor (12).
