34 results about "Radiation-induced lung injury" patented technology

A system and computation method is disclosed that identifies radiation-induced lung injury after radiation therapy using 4D computed tomography (CT) scans. After deformable image registration, the method segments lung fields, extracts functional and textural features, and classifies lung tissues. The deformable registration locally aligns consecutive phases of the respiratory cycle using gradient descent minimization of the conventional dissimilarity metric. Then an adaptive shape prior, a first-order intensity model, and a second-order lung tissues homogeneity descriptor are integrated to segment the lung fields. In addition to common lung functionality features, such as ventilation and elasticity, specific regional textural features are estimated by modeling the segmented images as samples of a novel 7th-order contrast-offset-invariant Markov-Gibbs random field (MGRF). Finally, a tissue classifier is applied to distinguish between the injured and normal lung tissues.

The invention relates to the field of traditional Chinese medicines, in particular to a traditional Chinese medicine preparation for preventing and treating yin deficiency and lung heat radiation-induced lung injury. The traditional Chinese medicine preparation is prepared from the following raw materials in parts by weight: 30-90 parts of radix glehniae, 30-90 parts of fleshly scale leaf of lily, 15-45 parts of the root bark of white mulberry, 30-90 parts of rhizome of paris polyphylla, 10-30 parts of bulbus fritilariae, 15-45 parts of earthworm, 10-30 parts of herbaceous stem of ephedra, 15-45 parts of root-bark of tree peony, 10-30 parts of platycodon, 10-30 parts of semen armeniacae amarae, 10-30 parts of rhizoma anemarrhenae, 15-45 parts of holly leaves, 30-90 parts of rhizoma phragmitis, 15-45 parts of snake gourd fruits and 10-30 parts of liquorice root. The traditional Chinese medicine preparation is reasonable in design, avoids the effect of venous drugs and resulting side effects on the body of a patient, also avoids limitation caused by indication mastery, and overcomes the shortcomings of limitation of methods such as oral preparation of the traditional Chinese medicines to clinical observation and empirical antibiotics treatment.
