Method and device for avoiding blurring in medical imaging techniques, caused by the patient's movement during image recording
DE 3447365 A1
Résumé
In medicine there are imaging techniques which require a relatively long time to compile the image. During this time the patient must not alter his position. This causes problems inasmuch as it is virtually impossible for a patient to keep his head (for example) still for, say, ten minutes. Fastening the head with straps over this period is an unreasonable demand to make on the patient, especially in the case of children. The problem is solved by the invention in that the position of the patient is recorded in a computer (positional computer), continuously or at intervals which are short relative to the image acquisition, and in that the respective determination of the patient's position affects either the sampling program (the sampling sequence) or the allocation of the sampled measurement values to a point in the patient's body. This can be realised by continuous coordinate transformations which convert a spatially fixed coordinate system to one related to the patient's body.
