[1] The technical name for this procedure is cryosection. The microtome device that cold cuts thin blocks of frozen tissue is called a cryotome.
A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method). Consider the differential equation. and denote the step size by . First, the predictor step: starting from the current value , calculate an initial guess value via the Euler ...
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown. Removing infected pulp during a root canal procedure. Root canal treatment (also known as endodontic therapy ...

This surgery is complex and may vary slightly depending on the diagnosis and overall condition of the heart. The surgery on the heart can be divided into two main steps.
Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [1] [2] Atmospheric effects in optical remote sensing are significant and complex, dramatically altering the spectral nature of the radiation reaching the remote ...
Blalock–Thomas–Taussig shunt. The Blalock–Thomas–Taussig shunt ( BTT shunt ), [1] previously known as the Blalock-Taussig Shunt ( BT shunt ), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of ...
Endoscopic third ventriculostomy ( ETV) is a surgical procedure for treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole. This allows the cerebrospinal fluid to flow directly to the basal cisterns, bypassing the obstruction.
