Abstract: Methods and systems for alignment of a subject for medical imaging are disclosed, and involve providing a reference image of an anatomical region of the subject, the anatomical region comprising a target tissue, processing the reference image to generate an alignment reference image, displaying the alignment reference image concurrently with real-time video of the anatomical region, and aligning the real-time video with the alignment reference image to overlay the real-time video with the alignment reference image. Following such alignment, the subject may be imaged using, for example, fluorescence imaging, wherein the fluorescence imaging may be performed by an image acquisition assembly aligned in accordance with the alignment.

Abstract: An imaging device having an imaging field of view, the imaging device including at least one illumination port configured to output light for illuminating a target; an imaging sensor to detect light traveling along an optical path to the imaging sensor; and a first movable window positioned upstream of the sensor with respect to a direction of travel of light along the optical path, wherein the first movable window is configured to move into the optical path in a deployed position for modifying light received from the target.

Abstract: Described herein are introducer devices and methods for using an introducer device to facilitate passing an endoluminal instrument to a target region of a body cavity. An introducer device may include a tubular member having an inner wall that defines a channel configured to receive the endoluminal instrument and a plurality of projections disposed in the channel at perimetrically spaced apart locations around the inner wall, where the projections extend inward and are configured to offset the endoluminal instrument from the inner wall, thereby creating a space between the endoluminal instrument and the inner wall. A method for using an introducer device may include passing the endoluminal instrument to a first instrument insertion depth within the introducer device, advancing the introducer device in the body cavity, and advancing the endoluminal instrument to a second instrument insertion depth within the introducer device.

Abstract: Systems and methods for storing data for a first time series of fluorescence images of the subject acquired during a first imaging session, storing data for a second time series of fluorescence images of the subject acquired during a second imaging session, receiving a request to view attributes of the subject, and in response to receiving the request, displaying a user interface on the display, the user interface comprising a first image showing a visually enhanced attribute of the subject, wherein the first image is generated from the data for the first time series of fluorescence images, and a second image showing the visually enhanced attribute of the subject, wherein the second image is generated from the data for the second time series of fluorescence images.

Abstract: An imaging device may include a first illumination port to output first light having a first illumination distribution at a target to illuminate the target, a second illumination port to output second light having a second illumination distribution at the target to illuminate the target, the second illumination distribution being substantially similar to the first illumination distribution at the target, the second illumination port being spaced apart from the first illumination port, the first and second illumination distributions being simultaneously provided to the target and overlapping at the target. The illumination from the first and second ports may be matched to a same aspect ratio and field of view coverage as the imaging field of view.
