The image-handling and medical-archiving system PACS has many capabilities and is especially flexible in the many image types it handles. Whatever kind of test is needed in a patient’s care, PACS is likely able to store the resultant image and make it available to the appropriate medical staff. Here are some examples of tests the results of which may be captures by PACS:

• Ultrasound – sound waves generate a visual depiction of structures under the skin; commonly used to detect or examine pregnancy.
• Magnetic Resonance (MRI) – magnetic waves indicate internal structures with great detail.
• Positron emission tomography – a nuclear imaging technique that creates a 3D image of active bodily processes.
• Computed tomography – uses two X-rays to craft a 3D depiction of an object’s insides.
• Endoscopy – a device called an endoscope is inserted directly into an organ for a first-hand look around.
• Mammograms – use X-rays to examine women’s breasts to check for cancer and other potential medical problems.

There are many more such examples. PACS system strengths lie in the way it can not only archive these images but also distribute them to anyone on the network with the appropriate authorization, as opposed to the old method of carrying hard copies around.

The PACS system is used for four primary functions. It replaces physical copies of images, greatly reducing waste and inefficiency. It allows remote access to files, which makes for faster response times. It serves as an electronic image integration platform, which means it helps radiology images interface with images from other automated systems. Finally, radiology departments often use PACS to control the patient exam workflow.
