Information for Health
An Information Strategy for the Modern NHS 1998-2005
![Page 18: Information Technology in Healthcare](https://reader031.vdocuments.us/reader031/viewer/2022012919/56815e30550346895dcc8c62/html5/thumbnails/18.jpg)
Top level commitment
“The challenge for the NHS is to harness the information revolution and use it to
benefit patients”.
Rt. Hon. Tony BlairAll Our Tomorrows Conference 2 July 1998
![Page 19: Information Technology in Healthcare](https://reader031.vdocuments.us/reader031/viewer/2022012919/56815e30550346895dcc8c62/html5/thumbnails/19.jpg)
Purpose of the strategy. . . . to put in place over the next seven
years the people, the resources, the culture and the processes necessary to ensure NHS clinicians and managers
have the information needed to support the core purpose of the NHS. And to ensure the public and patients have a range of quality information easily accessible about health and
health services.

Defining electronic records Electronic Patient Record - a record of
periodic care provided by one institution, typically an acute hospital
Electronic Health Record - the concept of a longitudinal record of a patient’s health and healthcare to combine information from primary healthcare with periodic care from other institutions

Magnetic Resonance ImagingProtons in a magnetic field have a microscopic magnetization and act like tiny toy tops that wobble as they spin. The rate of the wobbling or precession is the resonantor Larmor frequency. In the magnetic field of an MRI scanner there is approximately the same number of proton nuclei aligned with the main magneticfield as counter-aligned.On a macroscopic level, exposure of an object or personto RF radiation at the Larmor frequency, causes the net magnetization to spiral away from the static field.Relaxation is the process whereby nuclear magnetization returns to its resting state following a perturbation, such as by an RF pulse.
