Filed:

Sep 20, 2001

Appl. No.:

09/957946

Inventors:

David M. Boisvert - Windham NH, US
Joseph D. Clark - Hudson NH, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K009/38

US Classification:

382270, 382312, 382318

Abstract:

A linear pixel-array processing systems uses a combination of digital and analog signal processing techniques to calibrate the gain and offset of each pixel in the analog domain. A plurality of fixed gain and offset values are applied in the analog domain to adjust the gain and offset of each pixel at high speeds (on the order of 25–50 MHz). By adjusting the gain and offset in the analog domain, the dynamic range of pixel conversion is improved such that the conversion range is fully utilized (over 90%, on the order of 95%–99%). The gain and offset values are determined with an algorithmic calibration routine that corrects for non-ideal effects in the signal path. A single processing channel can be multiplexed to process multiple pixel arrays to provide for a cost effective solution. In higher speed systems, the single processing channel can be extended to multiple processing channels for improved throughput.

Abstract:

Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.
