The present invention is a system and method for identifying certain physical properties of human feet. The system uses electronic and optical elements to perform before and after pronation test and before and after arch tests (meaning before and after use of an orthotic), and develop a 360 degree, three-dimensional view of the foot.

The present invention generally relates to a dental intraoral scanner system. In detail, the present invention includes: a scan unit sequentially imaging an intraoral structure in a scan mode; a control unit generating a three-dimensional modeling image for each scan mode by using the imaged intraoral structure; and a display unit displaying the three-dimensional modeling image, wherein the control unit switches the scan unit from a present scan mode to a following scan mode according to a user's command that is input through the scanning unit, or automatically switches from the present scan mode to the following scan mode when a three-dimensional modeling image of the present scan mode is completed.

An apparatus and method for determining contours of a patient's foot ankle and lower leg. The apparatus includes an alignment structure that orientates the foot for imaging. The alignment structure includes at least one support member that engages the plantar surface of the foot substantially only in the immediate area of the lateral metatarsal heads of the foot, preferably the fifth metatarsal head. The support generates a dorsally-directed force that locks the midtarsal joint. The alignment structure further includes a saddle that engages the rearfoot and a laser beam for aligning the second metatarsal head with the distal one-third of the lower leg to place the subtalar joint in a neutral condition. The foot is thus suspended in space such that imaging is able to produce an accurate measurement of the subject areas of the foot, ankle and lower leg without distortion of the soft tissues or bone structure.

An imaging apparatus includes: a light source section (2, 40) including a light source having a wavelength of a plurality of bands; an imaging section (15) configured to convert measurement light source light images of the plurality of bands from the light source section into a plurality of electrical measurement imaging signals, the measurement light source light images being reflected from a surface and an inside of the subject; a calculation section (13, 16, 19) configured to measure a shape of the surface and a shape of the inside in the subject based on the plurality of electrical measurement imaging signals obtained through the conversion in the imaging section; and a composition processing section (19) configured to composition-process the shape of the surface and the shape of the inside measured by the calculation section to create two-dimensional image data or three-dimensional image data about the subject.

A medical data processing method of determining a transformation for determining a breathing state-dependent geometry of an anatomical body part of a patient's body, the method comprising: a) acquiring planning image data describing a set of tomographic medical planning images describing each a different part of the anatomical body part in the same respiratory state called reference planning respiratory state, wherein the anatomical body part is subject to respiratory movement and wherein the planning images comprise a planning image called reference planning image describing a part of the anatomical body part which is called reference planning body part; b) acquiring breathing image data describing a set of tomographic medical breathing images of the anatomical body part, wherein the breathing images comprise a reference breathing image describing the reference planning body part in a respiratory state called reference breathing respiratory state, which is different from the reference planning respiratory state, and a target breathing image describing at least another part of the anatomical body part, wherein the other part of the anatomical body part is called target body part, in a respiratory state called target respiratory state which is different from the reference planning respiratory state; c) determining, based on the planning image data and the breathing image data, reference transformation data describing a transformation, called reference transformation, between the geometry of the reference planning body part in the reference planning respiratory state and the geometry of the reference planning body part in the reference breathing respiratory state; d) acquiring scaling factor data describing a scaling factor which describes a relationship between the geometry of the reference planning body part in the reference breathing respiratory state and the geometry of the target body part in the target respiratory state; e) determining, based on the reference transformation and the scaling factor data, derived transformation data describing a transformation called derived transformation between the geometry of the target body part in the reference planning respiratory state, and the geometry of the target body part in the reference breathing respiratory state.

A system for sizing and fitting an individual for apparel, accessories, or prosthetics includes at least one energy emitter configured to emit energy onto a field-of-view that contains an individual, and at least one energy sensor configured to capture reflected energy from within the field-of-view. A spatial measurement module calculates spatial measurements of a surface portion of the body of the individual when the individual is either stationary or moving about in real-time, based on data from the energy sensor.

Disclosed are methods and an assembly for robust one-shot interferometry, in particular for optical coherence tomography according to the spatial domain approach (SD-OCT) and/or according to the light-field approach. In one embodiment, the method and the assembly may be used for measurements on material and living tissue, for distance measurement, for 2D or 3D measurement with a finely structured light source imaged onto the object in a diffraction-limited way, or with spots thereof. The assembly may comprise an interferometer having object and reference arms and a detector for electromagnetic radiation. In other embodiments, during a detection process, a plurality of spatial interferograms may be formed by making an inclined and/or curved reference wavefront interfere with an object wavefront for each measurement point. The resulting spatial interferograms may be detected in a single detector frame and may be further evaluated via a computer program.

An intra-oral imaging apparatus for obtaining a contour image of a tooth has a fringe pattern generator energizable to emit a fringe pattern illumination. The fringe pattern generator has (i) at least one structured light source that is energizable to emit a patterned light beam; (ii) at least one reflective element in the path of the emitted patterned light beam and actuable to rotate about an axis to scan the emitted patterned light beam along a tooth surface as fringe pattern illumination. A detector is configured to acquire one or more images of the fringe pattern illumination from the tooth surface. A control logic processor is configured to control the fringe pattern generator for illuminating the tooth and to obtain and process the one or more images acquired by the detector.
