Acoustic Emission: Can This Technology Be Used to Diagnose Arthritis? (270 words) |
 | At the University of Central Lancashire, a research team is working to develop a hand-held device based on acoustic emission to detect these differences and help primary care physicians diagnose arthritis. |
| Theoretically the acoustic emission hand-held device would help monitor the effectiveness of arthritis treatments as well. |
| According to the Arthritis Research Campaign "acoustic emission has been used extensively in the engineering industry to detect unsafe buildings and bridges." The hope is that acoustic emission can be used to assess knee damage in the clinical setting. |

| The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right of the picture. |
| Immediately to its left are a cluster of of prominent bluish reflection nebulae sometimes called the Running Man. The Horsehead nebula appears as a dark cloud, a small silhouette notched against the long red glow at the lower left. |
| Below Alnitak is the Flame Nebula, with clouds of bright emission and dramatic dark dust lanes. |
