Embodiment Construction

[0013] Before the present invention is disclosed and described, it is to be understood that the invention is not limited to the specific structures, method steps or materials disclosed herein but extends to equivalents thereof recognized by those skilled in the art. Also please understand that the terminology used herein is for the purpose of describing specific embodiments only and not for limitation.

[0014] As a preliminary note, note that much of the discussion here relates to the dental profession and performing dental exams and procedures. However, this is for demonstration purposes only, as the systems and methods described herein are also applicable to other medical professionals who benefit from high magnification stereoscopic imaging and tracking of desired sites for surgery or examination. For example, the systems and methods herein are particularly useful for imaging of locations where movement occurs, such as minimally invasive surgery while the patient is awake ...

Abstract

Systems and methods for viewing stereoscopic video images are disclosed. One system comprises a first video camera configured to generate a first video feed of a subject. A second video camera is spaced a pupilary distance from the first video camera and configured to generate a second video feed of the subject. A tracking module associated with the first video camera and the second video camera is configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis. A zooming module associated with the first video camera and the second video camera is configured to provide a desired magnification of the near real-time stereoscopic video image.

Description

technical field Background technique [0001] Dentistry has made significant technological advances in practice. These advances have enabled better patient care and reduced patient anxiety when visiting the dentist. [0002] Many of the technologies that dentists use to provide advanced care today include the ability to see and focus on the smallest details in a patient's mouth. Lenses with magnifying rings are also often used by dentists to increase their ability to see fine details. These lenses are expensive and bulky, and can become a burden for dentists to wear for long periods of time. In addition, magnification rings can also cause eye fatigue and tubular vision, reducing the dentist's ability to view both the magnified area and the surrounding area. [0003] Additionally, the dentist often has to lean forward and arch the back in order to obtain the desired view of the area within the patient's mouth. This posture can cause long-term health problems for the dentist...
