Fully Automated Bone Mineral Densitometry on Routine CT Scans


The invention relates to an improved system for measuring bone mineral density (BMD). BMD measurement is an important tool for the diagnosis of osteopenia- and osteoporosis-related fractures, a significant national health problem primarily affecting the elderly and women after menopause. More specifically, the invention relates to an algorithm and software for fully automating BMD measurement, using routine CT data and eliminating the need for a reference phantom or a specialized imaging protocol. The current standard methods not only require reference phantom to be placed underneath the patient and a specialized imaging protocol, but they also require manually placed regions of interest (ROI) to identify the appropriate bone structures. The benefit of the automated method provided in the invention is that with this system BMD measurement will be available for every patient with chest/abdominal CT scan (millions are done every year) so that the potential low bone mineral density can be discovered.

Potential Commercial Applications: Competitive Advantages:
  • The technique can be integrated to a CT scanner to provide automated measurement of BMD for every CT scan.
  • The technique can be integrated into PACS (Picture Archiving and Communication Systems) to report BMD at the time of image interpretation by the radiologist or clinician.
 The technique can be readily integrated to existing medical imaging systems such as CT scanners (to provide BMD measurement with every CT scan) or PACS (to report BMD at the time of image interpretation).


Development Stage:
  • Prototype
  • In vivo data available (human)
