IT in Healthcare
ICT is widely used in the health sector to improve patient care
and hospital management. For example, a Hospital Management
System helps keep track of patients’ records and manage hospital
activities. Computers are also used in medical machines like ECG,
EEG, Ultrasound, and CT Scanners to help doctors diagnose and
monitor health conditions. Expert systems assist in diagnosing
diseases, while health care companies use computers to produce
diagnostic tools and instruments. Additionally, computers are essential in laboratories and pharmacies for
scanning and diagnosing various diseases.
Use of ICT in Diagnosis
With the advancements in computer hardware and software technology, various high-tech machines are used
in the diagnosis and treatment of critical diseases. Using expert system, diseases can be diagnosed at the
early stages and the patients can be given treatment accordingly. Some of these machines are:
Computerised Axial Tomography (CAT) Machine: This device produces
three-dimensional (3D) images of different body parts, aiding in the detailed
diagnosis of diseases.
Magnetic Resonance Imaging (MRI) Machine: MRI machines use strong
magnetic fields and radio waves to create detailed digital images of internal
organs. These images are crucial for detecting and planning the treatment of
various conditions.
Electrocardiogram (ECG) Machine: The ECG machine monitors the heart’s
electrical impulses, providing a graphical representation of heartbeats. This
helps in diagnosing and assessing heart conditions.
Cardiac Screening Machine: This machine visualises the physiology of the heart
and displays its movements, allowing for the diagnosis of heart issues, such as
vein thinning, and facilitating appropriate treatment.
Electroencephalography (EEG) Machine: The EEG machine records brain
activity by detecting electrical impulses through small probes attached to the
scalp. It captures data whether the patient is awake or asleep, aiding in the
diagnosis of neurological conditions.
Blood Sugar Testing Machine: This device analyses blood samples to determine
glucose levels, assisting in the management and diagnosis of diabetes.
