Abstract:
Systems and methods are disclosed for making three-dimensional models of the inside of an ear canal using a projected pattern. A system comprises a probe adapted to be inserted into the ear canal. The probe comprises a narrow portion adapted to fit inside the ear canal and a wide portion adapted to be wider than the ear canal, which may be formed by a tapered stop. An illumination subsystem projects a pattern of light from the distal end of the probe onto a surface of the ear canal, the pattern being modulated by the three-dimensional surface of the ear canal. An imaging subsystem captures a series of individual images of the pattern of light projected onto the surface of the ear canal. A computer subsystem calculates digital three-dimensional representations from the individual images and stitches them together to generate a digital three-dimensional model of the ear canal.

A customized sealing member is for a customized mask of a pressure support system. The steps to manufacture the customized sealing member include generating surface geometry data of a face of a patient, the surface geometry data corresponding to and representing a surface geometry of the face of the patient; generating customization data using the surface geometry data, the customization data representing how a seal blank should be modified for the patient; and customizing the seal blank using the customization data such that the customized seal blank is shaped according to the customization data.
Abstract:
Direct anterior approach (DAA) with the patient lying supine has facilitated the use of intraoperative fluoroscopy and allows for standardized positioning of the patient. The method disclosed herein uses intraoperative fluoroscopy to measure acetabular component anteversion and more particularly, a method for measuring/calculating intraoperative cup (acetabular component) anteversion is provided based on the measured acetabular component abduction angle and a c-arm tilt angle (CaT).
