Method for generating patient-specific implants

An implant is generated which is functionally and aesthetically adapted to the patient with a greater degree of precision, irrespective of the size, form and complexity of the defect, whereby the implant can be produced and operatively inserted into the patient over a short time period and in a simple manner. A virtual three-dimensional model of the patient which is formed from existing recorded (two-dimensional) image data of the patient is compared with real medical reference data. The comparison which is, for example, carried out using a data bank with test person data enables a reference model object which is most suited to the patient or closest to the patient model to be selected or formed and a virtual implant model is generated accordingly. Computer numeric control data is directly generated from the implant model which is generated virtually in the computer for program-assisted production of the implant.

Method and system to increase X-Y resolution in a depth (Z) camera using red, blue, green (RGB) sensing

An imaging system substantially simultaneously acquires z-depth and brightness data from first sensors, and acquires higher resolution RGB data from second sensors, and fuses data from the first and second sensors to model an RGBZ image whose resolution can be as high as resolution of the second sensors. Time correlation of captured data from first and second sensors is associated with captured image data, which permits arbitrary mapping between the two data sources, ranging from 1:many to many:1. Preferably pixels from each set of sensors that image the same target point are mapped. Many z-depth sensor settings may be used to create a static environmental model. Non-correlative and correlative filtering is carried out, and up-sampling to increase z-resolution occurs, from which a three-dimensional model is constructed using registration and calibration data.
