SYSTEM AND METHOD FOR THREE-DIMENSIONAL DEPTH IMAGING

摘要

The invention relates to an imaging system and method aimed at constructing a three-dimensional depth image of a patient, which is particularly useful in the field of medical imaging, in particular in the field of X-ray imaging of moving patients. The system includes first imaging means 18 comprising at least one stationary surface-imaging device 3 allowing the acquisition of a sequence of two-dimensional surface images 4 of a patient 2, and a computer processor including a first reconstruction module 5 for constructing a sequence of three-dimensional surface representations 6 of a patient 2 from a series of simultaneous two-dimensional surface images taken in each sequence of two-dimensional surface images 6 acquired by the first imaging means. Second imaging means 19 comprise at least one stationary depth-imaging device 7 allowing the acquisition of a sequence of several two-dimensional depth images 8 of a patient. The computer processor includes a second reconstruction module 9 for constructing a three-dimensional depth representation 1 of the patient from a sequence of three-dimensional surface representations of a patient constructed by the first reconstruction module and a sequence of two-dimensional depth images of the patient acquired by the stationary depth-imaging device.
