Figures

Image of FIG. 1.
FIG. 1.

(a) An (analog) optical processing architecture for analog radiographs. A region of a mammogram (b) prior to and (c) after optical processing. (Reprinted with permission from Ref. 5.)

Image of FIG. 2.
FIG. 2.

Schematic diagram of a laser-scanning film digitizer. (Reprinted with permission from Ref. 12.)

Image of FIG. 3.
FIG. 3.

Examples of (a) a PA template image and (b) lateral template images used in an automated system to differentiate PA and lateral radiographic chest images retrieved from a PACS. (Reprinted with permission from Ref. 24.)

Image of FIG. 4.
FIG. 4.

Magnetic resonance (MR) images after compression and uncompression with the (a) JPEG (discrete cosine transform) and (b) wavelet compression algorithms. The corresponding error images are shown also for the (c) JPEG and (d) wavelet algorithms. (Reprinted with permission from Ref. 33.)

Image of FIG. 5.
FIG. 5.

The TG18-QC test pattern. (Reprinted with permission from Ref. 46.)

Image of FIG. 6.
FIG. 6.

(a) The correction grid along with (b) the original, distorted image from an image intensifier and (c) the image corrected with a local unwarping polynomial. (Reprinted with permission from Ref. 61.)

Image of FIG. 7.
FIG. 7.

The top row shows coronal sections from the CT scan of a normal breast. The bottom row shows the same sections after application of a dedicated noise removal algorithm. (Reprinted with permission from Ref. 71.)

Image of FIG. 8.
FIG. 8.

Chest radiographs of the same patient acquired at different times. (a) Previous and (b) current images. (c) The temporal subtraction image clearly depicts change in the left upper lobe lung nodule (arrow). (Courtesy of H. MacMahon, M.D., The University of Chicago.)

Image of FIG. 9.
FIG. 9.

Dual-energy chest radiography may be used to produce (a) a standard radiographic image, (b) a soft-tissue image, and (c) a bone image. The nodule demonstrated in the standard radiographic image (arrow) may be identified as a calcified granuloma since it appears in the bone image (arrow) but not the soft-tissue image. (Reprinted with permission from Ref. 164).

Image of FIG. 10.
FIG. 10.

Radiographic image of the sacrum processed (a) with a standard unsharp-masking algorithm and (b) with a multiscale algorithm for the hierarchical enhancement of structures. (Reprinted with permission from Ref. 117.)
