Extremely high-quality radiation therapy

Extremely high-frequency therapy in oncology.

OBJECTIVE This article represents a review of the literature, mainly from Russian sources, dealing with the therapeutic application of low-intensity electromagnetic radiation in the millimeter band applied to experimental and clinical oncology. METHOD At the early stage of these studies, efficacy and safety of millimeter electromagnetic radiation (extremely high frequency [EHF]) was proved fo...

Quality control for Intensity-modulated radiation therapy

Labelmars.net: Crowd-sourcing an Extremely Large High Quality Martian

Improved toxicity profile following high-dose postprostatectomy salvage radiation therapy with intensity-modulated radiation therapy.

BACKGROUND With salvage radiation therapy (SRT) in the postprostatectomy setting, the need to deliver sufficient radiation doses to achieve a high probability of tumor control is balanced with the risk of increased toxicity. Intensity-modulated radiation therapy (IMRT) in the postprostatectomy salvage setting is gaining interest as a treatment strategy. OBJECTIVE Compare acute and late toxici...

Extremely High Velocity Outflows

Extremely high velocity (EHV) wings, with full widths of 72 to 140 km s, are seen on the CO J = 3→2 lines toward W3 IRS 5, GL 490, NGC 2071, W28 A2 (G05.89–0.39), GL 2591, S140, and Cepheus A. Observations of CO and CO J = 3→2 and J = 2→1 lines indicate that optical depth generally decreases with increasing velocity separation from the ambient cloud velocity. Maps of the extremely high velocity...
