Who uses Medical Image Data Transfers
Care Facilities, Physicians, and Patients
use medical image sharing to facilitate transfers between other facilities that may or may not be on the same network.
care facilities
use the technology to have immediate access to images, as opposed to waiting for physical media to arrive. Having access to a patient’s medical history improves the point of care service.
physician
able to receive their imaging exams electronically, without needing to carry and store physical media. It allows for the ability to see physicians in multiple locations and have their imaging at the ready.
patients
use is to promote the spread of electronic health records to improve health care in the United States, which is to be rolled out in 3 stages through 2015
meaningful use
promotes the use of telehealth technologies. Sharing medical images over long distances can happen instantaneously with these technologies, allowing a physician to review a patient’s images during the conference

telehealth
benefits of Medical image data transfer
Improved access to patients’ medical
imaging histories
Ability to view images instantly
Real-time collaboration by specialists
Avoiding duplicate care reduces costs
Decreased radiation exposure for patients
Expertise and specialized opinion is remotely accessible to patients
the physical transfer of data through a communication channel, such as wires, wireless technologies or physical media.
data transmission
Using software that is delivered as a service over the internet
cloud computing
can be set up to enable exchange, but this is typically requires more to maintain for the facilities involved.
VPN( virtual private network)
used to help facilitate the exchange of large files by encoding using smaller bits than the original version.
data compression
process helps reduce the resources being used and improves the transmission capabilities.
data transmission
TLS stands for
transport layer security
used to secure electronic communications

active directory
A medical imaging technology in which images and documents (and potentially any file of clinical relevance) are stored (archived) in a standard format with a standard interface, such that they can be accessed in a vendor-neutral manner by other systems
vendor neutral archive
A computerized medical record created in an organization that delivers care, such as a hospital or physician’s office.
electronic medical record
A computer-based information system that supports business or organizational decision-making activities.
decision support system
The mobilization of healthcare information electronically across organizations within a region, community or hospital system.
HIE health information exchange
health record where health data and information related to the care of a patient is maintained by the patient.
PHR personal health record
a standard for handling, storing printing, and transmitting information in medical imaging.
DICOM
focused on providing a standard-based specification for managing the sharing of documents between any healtcare enterprise, ranging from aprivate physician office to a clinic to an acute care in patent dacility and personal health record systemC
cross enterprise document sharing
requires the establishment of national standards for electronic health care transactions and national identifiers for providers, health insurance plans, and employers.
HIPAA- HEALTH INSURANCE PORTABILITY AND ACCOUNTABILITY
hopes of raising the overall meaningful use of health IT. It was created as a part of the American Recovery and Reinvestment Act of 2009. It also addressed security and privacy issues related to electronic exchange of medical information.
HITECH Act
HITECH act was instituted on
feb 17, 2009
A patient is provided with a highly visible, clickable button to download his or her medical records in digital form from a secure website offered by their doctors, insurers, pharmacies or other health-related service.
blue button
a network created to enable radiologists to share medical images with patients using personal health record (PHR) accounts
