SUV from PET image

Read the sections from the DICOM image, then SUV can be computed from the equation.

(0008,0032) [100209.015000] # AcquisitionTime

(0010,1030) [75] # PatientsWeight (kg)

(0018,1072) [090000.000000] # RadiopharmaceuticalStartTime

(0018,1074) [360100006.10352] # RadionuclideTotalDose (Bq)

(0018,1075) [6586.2] # RadionuclideHalfLife (seconds)

(0028,1052) [0] # RescaleIntercept

(0028,1053) [2.3295469284058] # RescaleSlope

Given X for a pixel value, Y= (RescaleIntercept + RescaleSlope X) exp(ln2*(AcqusitionTime- RadiopharmaceuticalStartTime)/ RadionuclideHalfLife)

SUV = Y/( RadionuclideTotalDose/ PatientsWeight)

Lung Motion


During breathing the thoracic cavity is expanded by contraction of the diaphragm and outer intercostal muscles. This causes changes in the intrapleural pressure which acts as a force upon the lung surface: Lung expands, and (since the pleu-ral cavity is filled with a fluid) during this process the visceral pleura is sliding frictionlessly down the internal surface of the thoracic cavity.uniform negative pressure is applied to a lung surface representing some initial state of breathing (e.g. state of end-expiration). This causes the lung to expand. We limit expansion by a geometry representing the lung shape at a final state of breathing (e.g. end-inhalation); see the fig. for illustration. If there occurs a contact between the two geometries, the contact is modeled to be frictionless. For simplistic purposes lung tissue is assumed to be an isotropic linear elastic and homogeneous medium.

div definition

Let x, y, z be a system of Cartesian coordinates on a 3-dimensional Euclidean space, and let i, j, k be the corresponding basis of unit vectors.

The divergence of a continuously differentiable vector field F = Fx i + Fy j + Fz k is defined to be the scalar-valued function:

\operatorname{div}\,\mathbf{F} = \nabla\cdot\mathbf{F} =\frac{\partial F_x}{\partial x} +\frac{\partial F_y}{\partial y} +\frac{\partial F_z}{\partial z}.


Although expressed in terms of coordinates, the result is invariant under orthogonal transformations, as the physical interpretation suggests.

The common notation for the divergence ·Fis a convenient mnemonic, where the dot denotes an operation reminiscent of the dot product: take the components of ∇ (see del), apply them to the components of F, and sum the results. As a result, this is considered an abuse of notation.
