ABSTRACT:
The invention relates to a method and to apparatus determining the exact position of a target relative to a reference of known co-ordinates. The apparatus comprises a source of radiation for forming an image of a target, which image is received by a receiver device situated beyond the target. A mask-forming device is interposed between the receiver device and the source of radiation, the mask-forming device including at least one localization means of known position relative to a reference point and suitable for forming an image in said image-forming radiation, means are also provided for displacing the radiation source in three dimensions, at least between two different angular positions, thereby displacing the co-ordinates of two different images of the target obtained from the two different angular positions of the source. The invention makes it possible to determine the exact position of a target with a very high degree of precision using a method which is simple and which limits the radiation dose. The target may be a cell or a stone or a bone to be treated.
