PPT-High Contrast Imaging with

JWSTCoronagraphy 2 High Contrast Imaging allows observing Extended emission surrounding stars Debris disks AGN hosts Faint companions High contrast imaging combines the suppression of light from the host optical cancellation with postprocessing by subtracting the scaled pointspread function PSF from the science image. 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 Dr .

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 .
