What is volumetric construction?
Volumetric construction, also called volumetric modular construction, is one type of modular construction. Another way to think about this is that all volumetric construction is modular construction, but not all modular construction is volumetric.
What is volumetric analysis?
Volumetric Analysis is also known as Titration. The titrant is the component whose solution is used to determine the concentration of an unknown solution. The component whose concentration is to be estimated is known as titrate. Titrimetric analysis is another name for volumetric analysis. There are three different types of volumetric analysis: 1.
What is a volume form used for?
A volume form provides a means to define the integral of a function on a differentiable manifold.
What is Volumetric Modulated Arc Therapy (VMAT)?
Volumetric Modulated Arc Therapy (VMAT) focuses the radiation on the tumor while protecting healthy tissues. Each Volumetric Modulated Arc Therapy (VMAT) treatment is completed in less than two minutes.
What is volume treated for?
The treated volume is the tissue volume which is planned to receive at least a dose selected and specified by the radiation oncologist as being appropriate to achieve the purpose of the treatment, e.g. tumour eradication, or palliation.
What is GTV and CTV?
The first of these two volumes is the position and extent of the primary tumour; this is known as the gross tumour volume (GTV). The second volume surrounds the GTV and describes the extent of microscopic, un-imageable tumour spread; this is known as the clinical target volume (CTV).
What is volumetric arc radiotherapy?
Volumetric modulated arc therapy (VMAT) is a novel radiation therapy technique that delivers the radiation dose continuously as the treatment machine rotates. This technique accurately shapes the radiation dose to the tumour while minimising the dose to the organs surrounding the tumour.
What is the difference between VMAT and IMRT?
VMAT is a type of IMRT technique. VMAT stands for Volumetric Arc Therapy. VMAT can also be called Rapid Arc. VMAT is different to normal IMRT in that the radiotherapy machine rotates around the patient during a radiotherapy beam in an arc shape.
What is CTV radiotherapy?
Purpose: The radiotherapy planning target volume (PTV) encloses the clinical target volume (CTV) with anisotropic margins to account for possible uncertainties in beam alignment, patient positioning, organ motion, and organ deformation.
What is the GTV?
The gross tumor volume (GTV) is defined as the gross palpable or visible/demonstrable extent and location of malignant growth.
What is the difference between EBRT and IMRT?
IMRT is a special form of EBRT involving the delivery of hundreds of small radiation beams with different intensities, entering the body from a number of different angles.
What is the difference between tomotherapy and IMRT?
Head-to-Head Comparison The researchers found, “Both VMAT and tomotherapy are capable of providing highly uniform target doses as compared with fixed field IMRT.” In terms of accuracy, tomotherapy delivered less toxicity to surrounding tissues.
What type of radiation is IMRT?
Overview. Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. IMRT uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor.
Why is Vmat better than IMRT?
Unlike IMRT, which typically includes less than 10 fixed-field beam angles, VMAT includes a large number of beam directions from an arc trajectory and delivers doses dynamically during rotation of the gantry.
Which is better IMRT or IGRT?
IGRT adds a technological advance to IMRT by providing imaging prior to each radiation session to ensure accuracy. Small localizing markers may be placed before treatment, then visualized to guide radiation delivery. Another IGRT option visualizes internal structures and uses those to line up each treatment.
What does Vmat mean in radiotherapy?
Volumetric Modulated Arc Therapy (VMAT) uses photons (W-rays) generated by a medical linear accelerator. Very small beams with varying intensities are aimed at a tumor and then rotated 360 degrees around the patient. This results in attacking the target in a complete three-dimensional manner.
What is SBRT used for?
SBRT is used to treat tumors in the lungs, spine, liver, neck, lymph node or other soft tissues.
What is 3dcrt?
A procedure that uses a computer to create a 3-dimensional picture of the tumor. This allows doctors to give the highest possible dose of radiation to the tumor, while sparing the normal tissue as much as possible. Also called 3-dimensional conformal radiation therapy and 3-dimensional radiation therapy.
What does Igrt stand for?
Image-guided radiation therapy (IGRT) is a method of radiation therapy that incorporates imaging techniques during each treatment session. Radiation therapy uses high-energy beams of radiation to control cancer and noncancerous tumors.
What is radiotherapy Wikipedia?
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator.
Volumetric Analysis
The method in which the concentration of a substance in a solution is estimated by adding the same number of compounds of another substance present in a solution of known concentration is called volumetric analysis. Volumetric Analysis is also known as Titration.
Principles of Volumetric Analysis
An unknown number of chemicals must be present in the solution which needs to be examined.
Procedure for Volumetric Analysis
A typical titration begins with a calibrated burette or pipette containing the titrant and a beaker or flask with a precise volume of the analyte and a small amount of indicator placed beneath it.
Volumetric Analysis Formulae and Important Terms
Normality= number of solute gram-equivalents /volume of solution (liters)
Things to Remember based on Volumetric Analysis
Volumetric Analysis is used to measure the concentration of a substance in a solution by adding the same number of compounds of another substance present in a solution of known concentration.
Important Questions based on Volumetric Analysis
Ans: In volumetric analysis, the concentration of a solution is determined by giving a known volume of the solution to react quantitatively with another solution of known concentration.
What is a volume form?
In mathematics, a volume form on a differentiable manifold is a top-dimensional form (i.e., a differential form of top degree). Thus on a manifold#N#M {displaystyle M}#N#of dimension#N#n {displaystyle n}#N#, a volume form is an#N#n {displaystyle n}#N#-form, a section of the line bundle#N#Ω n ( M ) = ⋀ n ( T ∗ M ) {displaystyle textstyle Omega ^ {n} (M)= {bigwedge }^ {n} (T^ {*}M)}#N#. A manifold admits a nowhere-vanishing volume form if and only if it is orientable. An orientable manifold has infinitely many volume forms, since multiplying a volume form by a function yields another volume form. On non-orientable manifolds, one may instead define the weaker notion of a density .
Is a Kähler manifold a volume?
Kähler manifolds, being complex manifolds, are naturally oriented, and so possess a volume form. More generally, the. n {displaystyle n}. th exterior power of the symplectic form on a symplectic manifold is a volume form.
Does a manifold have a volume form?
A manifold admits a nowhere-vanishing volume form if and only if it is orientable. An orientable manifold has infinitely many volume forms, since multiplying a volume form by a function yields another volume form. On non-orientable manifolds, one may instead define the weaker notion of a density .

A volumetric building module is different from other modular construction modules in ...
Why are volumetric buildings so efficient?
That means volumetric construction projects produce less waste. Adding to that bonus is the fact that many volumetric modular buildings are highly efficient, meaning they use less energy. That cuts down on both utility costs and costs to the environment.
How many sides are there in a volumetric building module?
A volumetric building module is different from other modular construction modules in that it is completely enclosed. This means that all six sides of the module are accounted for — one floor, four walls and one ceiling.
Why is volumetric construction important?
Volumetric construction often uses more materials in the assembly of each module. Each building module needs to be properly framed in order to fully and safely support itself. As a result, once the entire volumetric offsite construction project is stacked and connected together , you have the structural strength of the overall frame of the building and of each individual module that is in place.
What are the wasteful byproducts of the traditional construction process that you simply don’t have with volumetric modular
Vandalism, theft, over-buying materials, spoilage, weather damage — these are all wasteful byproducts of the traditional construction process that you simply don’t have with volumetric modular construction. That means volumetric construction projects produce less waste.
How many modules did Vesta deliver?
In under 90 days, VESTA designed and delivered 80 volumetric modules.
Is modular construction stronger than onsite construction?
While all construction is permitted and certified under the same codes and regulations, some severe weather data have shown that modular construction is stronger than traditional, onsite construction buildings and two-dimensional prefabricated buildings.
