Apparatus to capture three-dimensional images of a head comprises a plurality of image capturing device modules, each module comprises a plurality of image-capturing devices; and a rigid support structure supporting the plurality of image capturing device modules to define a space wherein an image of the head may be disposed. The rigid support structure supports all of the modules in predetermined relationship to each other and to the space. The rigid support structure further supports the modules in positions such that each module is positioned to capture a group of first images of a corresponding surface portion of a head disposed within the space such that each group of first images captured by the corresponding module captures a substantially different surface portion of the head disposed within the space.

The present invention provides assessment of cranial deformities. One embodiment for providing an on-line assessment comprises providing a server; and providing a database accessible by the server. The database comprises a plurality of image sets. Each image set comprises a plurality of images of a corresponding head shape selected from a plurality of head shapes. Each image is an image of the corresponding head shape from one viewing orientation of a plurality of predetermined viewing orientations. In one embodiment, the plurality of head shapes comprises a normal head shape and one or more head shapes selected from the group comprising a plagiocephalic head shape, a brachycephalic head shape, and a scaphocephalic head shape.

摘要:
A tool for depositing material onto a three-dimensional surface is described. The tool 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.
