Assignee: DENTSPLY SIRONA INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 6:
7. The dental x-ray imaging system according to claim 2,
wherein the image optimizer is configured to perform a calculation based on both x-ray sensor signal values associated with pixels of a dark current image and x-ray sensor signal values associated with pixels of one of the sequential x-ray images and/or the overall x-ray image of the patient tissue in order to optimize the x-ray image, and/or
wherein the image selector is configured to evaluate the or some of the sequential individual x-ray images using predefined criteria in order to select from among them suitable, in particular sufficiently congruent, individual x-ray images or reject unsuitable, in particular overly incongruent individual x-ray images, and/or
wherein the motion detector is configured to allocate pixels of temporally sequential individual x-ray images to a substantially identical section of the patient tissue in order to detect the motion occurring between and/or during the sequential individual x-ray images, and/or
wherein the motion compensator is configured to align, particularly bring to congruence, the pixels of the temporally sequential individual x-ray images allocated to the substantially identical section of the patient tissue by means of image transformation, in order to harmonize these x-ray images with one another and/or
wherein the image combiner is configured to perform a calculation based on x-ray sensor signal values of corresponding pixels of the temporally sequential, in particular harmonized, individual x-ray images in order to combine these individual x-ray images to the overall x-ray image.
