Information for Health
An Information Strategy for the
Modern NHS 1998-2005
Top level commitment
“The challenge for the NHS is to harness
the information revolution and use it to
benefit patients”.
Rt. Hon. Tony Blair
All Our Tomorrows Conference 2 July 1998
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 Imaging
Protons 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 resonant
or Larmor frequency.
In the magnetic field of an MRI scanner there is approximately
the same number of proton nuclei aligned with the main magnetic
field as counter-aligned.
On a macroscopic level, exposure of an object or person
to 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.
