PPT-Imaging problems Depth of field in imaging

But not ideal Maps and blurs a very narrow angle range from one object point Dq rL to one image point Depth of field in imaging Sometimes a nice effect sometimes a problem. Traditionally clinical imaging exploits the contrast due to differences in spin density spinlattice relaxation T and spinspin relaxation T between normal tissues and pathology However other contrast mechanisms such as susceptibility magnetization MRI USER GROUP.

Computed tomography (CT) is today commonly used in imaging of the maxillofacial area. Conventional CT examinations are usually performed in medical X-ray departments. However, a relatively new technique named cone-beam computed tomography (CBCT) or digital volume tomography (DVT) has now also become available for dental purposes. The advantage with this technique is a lower radiation dose compared to conventional CT. Common examples when DVT is used are; for diagnosing the position of impacted canines and suspected root .
