Abstract
A method, apparatus, system, and computer program product for automatically determining exposure time for an intraoral image. The method includes acquiring a low dose pilot projection image of an object to be imaged, performing a sanity check to ensure that a usable exposure is attainable, estimating a remaining exposure time required for an additional projection image, taking the additional projection image and adding the two images together to generate a final image wherein the dose delivered to the x-ray detector is influenced by patient specific dental anatomy.
Claims20
A method for automatically determining a required exposure time for an intraoral x-ray projection image, the method comprising:
- acquiring a low dose pilot projection image of an object to be imaged;
- performing a sanity check to ensure that a usable exposure is attainable;
- estimating a remaining required exposure time for obtaining one or more additional projection images, the estimating including determining that one or more final images will not be saturated by computing an estimated saturation exposure time required for saturation of an x-ray detector, and comparing said estimated saturation exposure time required for saturation with at least one of an estimated optimal exposure time and a maximum possible exposure time and
- responsive to determining that the one or more final images will not be saturated, obtaining the one or more additional projection images for one or more final images using the estimated remaining required exposure time such that a dose delivered to the x-ray detector is influenced by patient specific dental anatomy.
A system for automatically determining a required exposure time for an intraoral x-ray image, the system comprising:
- at least one processor operable to:
- acquire a low dose pilot projection image of an object to be imaged;
- perform a sanity check to ensure that a usable exposure is attainable;
- estimate a remaining required exposure time for obtaining one or more additional projection images by determining that one or more final images will not be saturated by computing an estimated saturation exposure time required for saturation of an x-ray detector, and comparing said estimated saturation exposure time required for saturation with at least one of an estimated optimal exposure time and a maximum possible exposure time and
- responsive to determining that the one or more final images will not be saturated, obtain the one or more additional projection images for one or more final images using the estimated remaining required exposure time such that a dose delivered to the x-ray detector is influenced by patient specific dental anatomy.
A non-transitory computer-readable storage medium storing a program which, when executed by a computer system, causes the computer system to perform a procedure comprising:
- acquiring a low dose pilot projection image of an object to be imaged;
- performing a sanity check to ensure that a usable exposure is attainable;
- estimating a remaining required exposure time for obtaining one or more additional projection images, the estimating including determining that one or more final images will not be saturated by computing an estimated saturation exposure time required for saturation of an x-ray detector, and comparing said estimated saturation exposure time required for saturation with at least one of an estimated optimal exposure time and a maximum possible exposure time and
- responsive to determining that the one or more final images will not be saturated, obtaining the one or more additional projection images for one or more final images using the estimated remaining required exposure time such that a dose delivered to the x-ray detector is influenced by patient specific dental anatomy.
