Deep Learning for the Radiographic Detection of periodontal Bone Loss [PDF]
, 2019 We applied deep convolutional neural networks (CNNs) to detect periodontal bone loss (PBL) on panoramic dental radiographs. We synthesized a set of 2001 image segments from panoramic radiographs. Our reference test was the measured % of PBL.

Image quality enhancement in digital panoramic radiograph
Journal of Artificial Intelligence and Data Mining, 2014 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.

A level crossing enhancement scheme for chest radiograph images
Computers in Biology and Medicine, 2007 A new approach for contrast enhancement of chest radiograph image data is presented. Existing methods for image enhancement focus mainly on the properties of the image to be processed while excluding any consideration of the observer characteristics. In several applications, particularly in the medical imaging area, effective contrast enhancement for ...
