A computer-assisted medical system comprises a fluoroscopic imager having a full scan range in a surgical coordinate space. The system further comprises one or more processors configured to perform a method. The method includes receiving a first fluoroscopic image data set of a patient anatomy. The first fluoroscopic image data set is obtained from the full scan range of the fluoroscopic imager. The method further includes receiving at least one additional fluoroscopic image data set of the patient anatomy from the fluoroscopic imager operating in a constrained range substantially smaller than the full scan range. The method further includes constructing a first planar tomographic image from the first and at least one additional fluoroscopic image data sets.

Systems and methods of pose estimation and calibration of perspective imaging system in image guided surgery

Information extracted from sequential images captured from the perspective of a distal end of a medical device moving through an anatomical structure are compared with corresponding information extracted from a computer model of the anatomical structure. A most likely match between the information extracted from the sequential images and the corresponding information extracted from the computer model is then determined using probabilities associated with a set of potential matches so as to register the computer model of the anatomical structure to the medical device and thereby determine the lumen of the anatomical structure which the medical device is currently in. Sensor information may be used to limit the set of potential matches. Feature attributes associated with the sequence of images and the set of potential matches may be quantitatively compared as part of the determination of the most likely match.

An apparatus may configure an illuminator to illuminate a scene with non-white light. The illuminator includes a plurality of color component illumination sources. The non-white light is light other than white light and is generated by a combination of light output by the plurality of color component illumination sources. The apparatus may also control a camera to capture, in a plurality of color channels of the camera, a frame of the scene illuminated with the non-white light and adjust pixel values of a color channel of the camera in the frame of the scene to decrease noise of the color channel in the frame of the scene.
