AI power is real but muzzled by lack of data sharing and standardization
AI adds a new dimension to brain and abdominal imaging in a number of clinical scenarios, but lack of data sharing as well as reproducibility and standardization issues must be…
Deep learning workflow in radiology: how to get started
In the past decade, deep learning architectures, which essentially consist of neural networks with numerous layers, have emerged as a dominant class of machine learning algorithms. Owing to the availability…
Bone Scan
Bone scan is an imaging technique that uses a radioactive compound to identify areas of healing within the bone. Bone scans work by drawing blood from the patient and tagging it…
Types of Medical Imaging
For certain types of clinical cases, imaging techniques can be used that do not require the use of ionizing radiation. For example, high-frequency sound waves are used in Ultrasound scans. In…
Molecular Imaging and Nuclear Medicine
Molecular imaging uses small amounts of radioactive markers, called radiopharmaceuticals, in the visualization and diagnosis of disease, including many types of cancer, heart disease, neurological disorders and other abnormalities in the body.…
Molecular Imaging
Molecular imaging is a relatively new discipline that allows the biological processes taking place in the body to be viewed at a cellular and molecular level. This breakthrough enables doctors to identify disease…
Magnetic Resonance Imaging
MRI systems use a powerful magnetic field and radiofrequency pulses to produce detailed images of the body’s internal structures as cross-sectional images or slices (Figure 1). Without exposing the patient…
Destroyers And Preservatives
The principal destroyers of wood are decay, caused by fungus, and attack by a number of animal organisms of which termites, carpenter ants, grubs of a wide variety of beetles,…
Effects Of Hygroscopic Properties Of Wood
Because of its nature, wood tends to absorb moisture from the air when the relative humidity is high, and to lose it when the relative humidity is low. Moisture imbibed into the…
Glass And Glass Block
Glass is so widely used for decorative and utilitarian purposes in modern construction that it would require an encyclopaedia to list all the varieties available. Clear glass for windows and…
