Abstract
Disclosed herein are systems and methods for adjusting appearance of objects in medical images.
Claims12
A method for adjusting appearance of objects in medical images, the method comprising:
- providing a computer wherein the computer receives a baseline image of a subject containing one or more objects, the baseline image taken with a baseline image quality and a baseline radiation dosage, and wherein the computer further receives an overlay image of the subject containing the one or more objects, the overlay image taken with an overlay image quality and an overlay radiation dosage:
- generating, by the computer, a difference image of the baseline image and the overlay image:
- generating, by the computer, a smoothed weight mask, wherein each pixel of the smoothed weight mask is a weighting;
- and
- generating, by the computer, a composite image of the baseline image and the overlay image with contribution of the baseline image and the overlay image determined by the smoothed weight mask,
- wherein the smoothed weight mask includes using soft weight values to construct a hybrid image, wherein the hybrid image is based on whether each pixel is above or below a defined cutoff value.

A method for adjusting appearance of objects in medical images, the method comprising:
- receiving, by a computer, a baseline image of a subject containing one or more objects:
- receiving, by the computer, an overlay image of the subject containing the one or more objects:
- transforming, the baseline image using a spatial transformation thereby generating a transformed baseline image:
- rescaling, by the computer, the overlay image using a scaling factor and an offset thereby generating a resealed overlay image:
- generating, by the computer, a difference image of the transformed baseline image and the rescaled overlay image:
- generating, by the computer, a smoothed weight mask, wherein each pixel of the smoothed weight mask is a weighting;
- and
- generating, by the computer, a composite image of the baseline image and the overlay image with contribution of the baseline image and the overlay image determined by the smoothed weight mask,
- wherein the smoothed weight mask includes using soft weight values to construct a hybrid image.
