Picture archiving and communication system

PACs allows for

Ability to share images with multiple viewers via web distribution.

Eliminating film usage, development and storage.

PACS ADVANTAGES

Fewer repeats

●#retakes due to lost films is fewer

●Availability of images in multiple locations (ER,ICU,OR)

●Faster report turnaround times/exam times

●Shorter patient waiting time

●Elimination of lost billing problems

Quality management is enhanced by the use of

PACS IN any radiology department

PACs when fully implemented allows

Allows for image acquisition but also interpretation and storage of each medical image in digital form without restoring to the hard copy film.

●Subtraction .

●Edge enhancement –

●Windowing —

●Highlighting –

●Scroll and zoom –

●Subtraction of one image from another. (Subtracting soft tissue from bone)

●Edge enhancement – effective for fractures and small, high-contrast objects.

●Windowing — useful for amplifying soft tissue differences.

●Highlighting – effective in identifying nonfocal disease

●Scroll and zoom – allow for visualizing precise regions of an image.
