An intravascular ultrasound (IVUS) imaging system and catheter with an intuitive interface for rapid operator interaction using acquired medical images. In an embodiment, an IVUS imaging system and catheter are used to acquire a sequence of a specific area of interest in the human anatomy, for example, tomographic images of a coronary artery. The IVUS imaging system displays at least one tomographic image of the area of interest. The IVUS imaging system generates and displays at least one longitudinal image, wherein the longitudinal image represents a cut-plane of the sequence of tomographic images. The IVUS imaging system further includes a touch screen, wherein the system recognizes touch movements to facilitate searching the sequence of images. Touch movements in a longitudinal direction may pan the longitudinal image in the longitudinal direction. Touch movements in the transverse direction may rotate the cut-plane of the longitudinal image. |

1. An intravascular ultrasound system, comprising:
a catheter configured to produce data; an interface module coupled to the catheter and configured to receive the data; and a console having a display with a touch screen coupled to the interface module, the console being configured to:
produce a sequence of tomographic images from the data acquired by the catheter,display at least a first image produced from the sequence of tomographic images on the display, the sequence of tomographic images combinable to form a three-dimensional image of an object, the three-dimensional image having a longitudinal axis extending therethrough, the first image representing a first cut-plane view at a cut-plane of the three-dimensional image, the cut-plane containing the longitudinal axis,display a cut-plane indicator on the display to indicate a first rotational orientation of the cut-plane corresponding to the first cut-plane view shown in the first image,receive a tactile input and determine a primary direction of movement of an object engaging the touch screen using at least one heuristic, the at least one heuristic comprises a first vertical screen scrolling heuristic for determining the primary direction of movement of the object engaging the touch screen,manipulate at least the first image based on the determined primary direction, the manipulation comprises rotating the orientation of the cut-plane to a second rotational orientation about the longitudinal axis in response to the first vertical screen scrolling heuristic, the first vertical screen scrolling heuristic being oriented in a direction perpendicular to the longitudinal axis,update the display to display a second image corresponding to a second cut-plane view of the three-dimensional image taken at the second rotational orientation of the cut-plane,update the display to display the cut-plane indicator oriented at the second rotational orientation at which the second image is taken. |
