Macrorad Teleradiology, PACS

F.A.Q.s

1) What is teleradiology?

Teleradiology is the process of sending radiologic images from one point to another through digital, computer-assisted transmission, typically over standard telephone lines, wide area network (WAN), or over a local area network (LAN). Through teleradiology, images can be sent to another part of the hospital, or around the world.

2) What is DICOM format?

DICOM (Digital Imaging and Communications in Medicine) is a standard that is a framework for medical-imaging communication. Based upon the Open System Interconnect (OSI) reference model, which defines a 7-layer protocol, DICOM is an application-level standard, which means it exists inside layer 7 (the uppermost layer). The standard was developed by the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA) with input from various vendors, academia, and industry groups. It is referred to as "version 3.0" because it replaces versions 1.0 and 2.0 of the standard previously issued by ACR and NEMA, which was called the "ACR-NEMA" standard. DICOM provides standardized formats for images, a common information model, application service definitions, and protocols for communication.

3) What is PACS?

PACS (Picture Archival and Communications System) is a computer system and network, which has the abililty to store, distribute and display radiological images in DICOM format. Electronic images and reports can easily be reached from anywhere in the world via PACS. Using PACS will eliminate the need to store hard copy films or reports. There are 4 major components of PACS system:
1) Medical imaging equipment (MRI, CT, Ultrasonography, digital x-ray)
2) Workstation: This is a powerful computer, which has advanced software for post-processing of radiologic images.
3) PACS server, which can store images, and can be reached either locally from a workstation or anywhere through internet.
4) A secure network between these structures.

4) What is the current status of Teleradiology ?

Teleradiology is a very fast-growing area. In US, the first teleradiology service was founded in 1993, however more than 80 % of the companies are founded after 2000. In Europe, the progress of teleradiology had similar footsteps. Teleradiology was first used within national borders. However, than these companies provide offshore emergency reports to hospitals in the United States. There are some restrictions to global teleradiology. The ACR recommends that radiologists who are performing distant readings be board-certified and carry licenses and malpractice coverage in the state where the image was obtained and appropriate credentials at the source facility. But in every single country, it is inevitable that teleradiology will grow, parallel to technology.

5) Can we do long-term archiving in Macrorad?

Sure, you can. We provide short term (3 month) archiving, free of charge. If you would like to do this for a long term period, you can have this option, with a price less than having your own PACS system.

6) Is there limits of coverage provided?

No. Coverage is provided 12 months, 7 days, 24 hours.

7) Can the physician of the patient easily reach to images?

Yes easily, with an internet connection and a browser.

8) Can the physician of the patient see postprocessing 3D, MPR or MIP images of a coronary CTA examination from a remote location?

Yes, beside every CT or MRI images, post-processed coronary or other CT/MR images can also be reached from a remote location.

9) We have problems with our 3D postprocessing results (e.g. inconsistent bone removal, bad vessel tracking, etc). Do you have any solutions?

Yes. Our 3D softwares and staff capability will resolve your problems. At least, you can work with us for a trial period to see the results.
