DEXSIT: A Benchmark Database for BMD Measurement and Analysis

Abstract

In the medical field, a bone mineral density (BMD) test is presented as a picture of your bone health. The test determines the risk for bone fractures of a human. From the test report one can identify the symptoms of osteopenia or osteoporosis disease which is the most common type of bone disease. The most extensively renowned BMD test is called a Dual-Energy X-ray absorptiometry, or DEXA test. The test can measure bone mineral density at spine, left and right femur bones. Superior properties of DEXA compared to conventional methods unveil the potential for new medical applications among the researchers. Thus it is mandatory to have a standard DEXA database for the researchers so as to take the treatments to the advance level by properly analyzing the clinical results of the scan images. The proposed DEXA database, named as DEXSIT, represents an initial attempt to provide a set of DEXA scan images of Anteroposterior (AP) spine, dual left and right femur bones. The database interprets all the clinical details such as age, weight, height, BMD level, T-score, Z-score and area of the bone part. In addition to describing the details of the database, some specific performance evaluation measures have also been done as an effort to make research achieved with the database as consistent and comparable as possible.
