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 19):
A computer system for opportunistic bone density screening, comprising:\n a receiver configured to receive 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; an image processor configured to process the CT image data to obtain a specified type of image relevant for that portion of the patient's body; an attenuation determining module executed at one or more processors configured to identify an attenuation value for one or more pixels in the processed image associated with the bone; a color palette provider configured to provide 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 a mapping module executed at the one or more processors configured to map the provided color palette to the processed image according to the identified attenuation values to opportunistically screen for abnormal bone density conditions.
