Abstract:
Embodiments describe an accurate and rapid method for assessing spinal bone density on chest or abdominal CT images using post-processed colored images. Post-processing of CT images for the purposes of displaying the spine is followed by color enhancement of routine unenhanced or contrast enhanced CT images to improve diagnostic accuracy, inter-observer agreement, reader confidence and/or time of interpretation as it relates to assessing bone density of the spine. CT images are post-processed (without changes to the standard-of-care CT imaging protocol and without additional cost or radiation for the patient) to straighten the spine for improved visualization of multiple segments. The color-enhanced images can be displayable simultaneously with the grayscale images. Methods and systems are provided for performing opportunistic bone density screening.

Claim (Index 1):
A method of opportunistic bone density screening, the method comprising:\n receiving, at an image processor, one or more portions of computed tomography (CT) image data obtained during a CT scan of a clinical indication unrelated to bone density using an image capture device, the CT image data including an image of at least a portion of a patient's body comprising a bone; processing the CT image data with the image processor to obtain a specified type of image relevant for that portion of the patient's body; identifying an attenuation value for one or more pixels in the processed image associated with the bone; providing a color palette comprising one or more colors, wherein the one or more colors are each related to a specific range of attenuation values, and wherein each specific range of attenuation values corresponds to one or more different bone density conditions; and mapping the provided color palette to the processed image according to the identified attenuation values to opportunistically screen for abnormal bone density conditions.
