Image quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...

متن کاملImage Registration for a Series of Chest Radiograph Images
To investigate the effect of treatment, a study on the progress of an MTB patient is carried out. One approach is to compare a series of chest radiographs taken at three different time points. For each radiograph a subset of the image representing the diseased area is derived, and henceforth monitoring is defined as the activity of comparing the three corresponding subset image. The elements of...
متن کاملProcessing Digital Image for Measurement of Crack Dimensions in Concrete
The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
