Abstract
Image processing systems are described which utilize various methods and processing algorithms for enhancing or facilitating visual detection and/or sensing modalities for images captured in vivo by an intravascular visualization and treatment catheter. Such assemblies are configured to deliver energy, such as RF ablation, to an underlying target tissue for treatment in a controlled manner while directly visualizing the tissue during the ablation process.

26. A method of imaging a tissue region, comprising:
-
visualizing one or more lesions over a tissue region within a body via an imaging catheter by viewing the tissue region through a viewing region purged of blood by a fluid; identifying a location of the one or more lesions relative to one another over the tissue region, the identifying performed with a computer; visually displaying the relative locations of each of the one or more tissue regions, the visually displaying performed with the computer, registering ablation parameters for each of the one or more lesions, the registering performed with the computer; and visually displaying the registered ablation parameters with the relative locations of each of the one or more tissue regions, the visually displaying performed with the computer. - View Dependent Claims (27, 28, 29, 30, 31, 32)

33. A method of imaging a tissue region, comprising:
-
visualizing one or more lesions in vivo over a tissue region within a body through an intravascular imaging catheter, the visualizing resulting in a plurality of visual images of the one or more lesions; measuring a temperature or an electrical potential of the one or more lesions, the measuring performed with a computer; and overlaying a gradient indicative of the temperature or the electrical potential upon one of the plurality of visual images of the one or more lesions captured in vivo, the overlaying performed with the computer; registering ablation parameters to the one of the plurality of visual images for each of the one or more lesions, the registering performed with the computer; and displaying the one of the plurality of visual images with the overlaid gradient and the registered ablation parameters, the displaying performed with the computer. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method of imaging a tissue region, comprising:
-
visualizing one or more lesions in vivo over a tissue region within a body through an intravascular imaging catheter; recording a color histogram of the one or more lesions during an ablation procedure, the recording performed with a computer; monitoring a rate of change of the color histogram during the ablation procedure, the monitoring performed with the computer; detecting an appearance of a color indicative of ablation completion of the one or more lesions, the detecting performed with the computer; and displaying the color histogram, the displaying performed with the computer. - View Dependent Claims (41, 42, 43, 44)
