Bone mineral analysis phantom |
| abstract |
A phantom (FIG. 1) has a bone mineral standard (B) surrounded by tissue equivalent material (A) with a plurality of different cross sections. The phantom is disposed in an image region (44) of a tomographic scanner (FIG. 2). Scans are conducted through a plurality of different cross sections of the phantom to reconstruct a plurality of phantom image representations (62). The plurality of phantom image representations are stored by size in a correction memory (70). Thereafter, a patient is disposed on a patient table (50) in the image region and an image is taken through the patient's mid-section between the L2 and L5 vertebrae. A patient image representation is reconstructed and stored in an image memory (64). A slice size calculation circuit (72) determines the size of the patient slice. The correction memory is addressed with the calculated size to retrieve the phantom image representation of the most similar size. An image correction circuit (74) calibrates the patient image representation in accordance with the retrieved phantom image representation. |
