Abstract:
A method of manufacturing a custom cranial remodeling orthosis device represented by a device data file partitions the device data file into a plurality of device portion data files each corresponding to a portion of the cranial remodeling orthosis device. The plurality of device portion data files are processed to provide a data file array comprising the device portion data files for manufacture by additive manufacturing apparatus to manufacture a corresponding array of a plurality of device portions of said cranial remodeling device.
Abstract:
A pediatric head covering to facilitate obtaining three-dimensional images of a head of an infant to be utilized in manufacture of a cranial remodeling orthosis for correction of an abnormal head shape comprises sheer elastic material to be drawn down over an infant's head to compress the hair of an infant and to provide a smooth surface over the infant's cranium. The elastic material has variable elasticity with less elasticity over the crown of the cranium to provide enough strength to compress the infant's hair and conform to the shape of the cranium and more elasticity at the infant's neck to control soft tissue of the infant's neck without leading to distortion of the soft tissue and causing misrepresentations of the actual neck shape in captured three-dimensional images. The head covering facilitates accurate capture and reproduction of three-dimensional images of the infant's head by a three-dimensional image capturing system. The head covering is sized based upon anthropometric data derived from three-dimensional data sets of infant heads.
Abstract:
Custom manufactured headwear for a subject's head is provided. The headwear comprises an inner layer shaped to contact the head of the subject at predetermined areas. The inner layer is deposited by an additive manufacturing device. The headwear further comprises an outer layer deposited by the additive manufacturing device. The inner layer and the outer layer are each formed by the additive manufacture device utilizing a device data file derived from a subject data file. The subject data file is representative of the shape of the head and the device data file determining the shape of the headwear.
Abstract:
A method for fabricating a custom headwear for a subject is described. The method comprises generating a three-dimensional head data file for the subject and determining contour lines on the head; automatically generating a headwear data file. The method further comprises juxtaposing the headwear represented by the headwear data file with the head represented by the three-dimensional head data file having the contour lines thereon. The method yet further comprises utilizing the headwear data file to generate a shape for a desired headwear, the shape having an interior surface to contact the head and an outer surface. Still further, the method comprises projecting lines outward from the contour lines to the outer surface; and utilizing the projected lines to establish headwear contour lines for the custom headwear.

Apparatus for processing a digital mesh representing a three-dimensional subject automatically filters out portions of a predetermined color to simplify further processing.
Abstract:
A method for producing a cranial remodeling device to correct for cranial shape abnormalities is described. One method comprises the steps of: providing cranial remodeling device trim line information; forming device material onto a three-dimensional model of a desired head shape; providing a machine responsive to said trim line information to move a spindle in a plurality of axes over the device material; providing a marking tool carried by the spindle; and operating the machine in response to the trim line information such that the machine moves the marking tool into surface engagement with the device material such that trim lines for the cranial remodeling device are marked onto the device material.
Abstract:
A tool for depositing material onto a three-dimensional surface comprises a first tubular member comprising a first guide surface and a second guide surface. The tool further comprises a second tubular member comprising a first guide surface engaging the first tubular member first surface and comprising a second guide surface engaging the first tubular member second surface. A first resilient member is disposed to urge the second tubular member in a first axial direction relative to the first tubular member. A tubular material holder is disposed axially within the second tubular member. A second resilient member is disposed in the tool to urge the holder in a second axial direction opposite to said first axial direction.
Abstract:
A method for processing digital image representations representative of a subject head shape comprises: providing a database library of a first plurality of first digital image representations of subject head shapes captured directly from corresponding subjects, and a second plurality of second digital image representations of corresponding modified head shapes. The method includes proving a support vector machine and utilizing the database library plurality of said first and second digital image representation to train the support vector machine to operate on new digital image representations. The method further includes receiving a new digital image representation of a subject head shape captured directly from a new subject; and operating the support vector machine such that the support vector machine operates on the new first digital image representation to generate a corresponding new second digital image representation that replicates a corresponding modified head shape.
