A system for visualizing a tissue region of interest comprises a deployment catheter defining a lumen and a hood coupled to and extending distally from the deployment catheter. The hood has a low-profile configuration within a delivery sheath and a deployed configuration when extended distally of the delivery sheath. The hood in the deployed configuration defines an open area in fluid communication with the lumen. A distal portion of the deployment catheter extends into the open area. An imaging element is coupled to an imager support member. When in the deployed configuration, the imaging element is configured to extend distally of the distal portion while the imager support member extends within the deployment catheter. The imaging element comprises a tapered surface and the deployment catheter comprises a complementary tapered surface. Retraction of the imaging element causes the imaging element to shift radially outward from a longitudinal axis.

Systems and methods for visualizing ablated tissue are disclosed. In some embodiments, a system for imaging tissue comprising: a catheter having a distal end and a proximal end; an inflatable balloon disposed about the distal end of the catheter; and an optical housing extending from the distal end of the catheter into the balloon, the optical housing being configured to position inside the balloon a light source for illuminating a tissue outside the balloon and a camera for imaging the illuminated tissue.

A medical system may comprise a display system and a processor. The processor may be configured to generate a computer model of a plurality of instruments. The plurality of instruments may extend through and out of a distal end of an entry guide and may include an image capturing instrument. The processor may be further configured to cause an image of the computer model to be displayed on the display system and determine from a configuration of the plurality of instruments in the computer model if an event alert threshold associated with an event has been reached. If a determination is made that the event alert threshold has been reached, an event indicator may be displayed on the display system at a portion of the image of the computer model associated with the event.

An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.
