Intensity Modulation of Pseudocolor Images [PDF]

BioTechniques, 1998
Fura-2 is a popular real-time fluorescent indicator used to image intracellular, free calcium concentrations ([Ca2+]i) in living cells. One difficulty with fura-2-based digital imaging is how to best display the [Ca2+]i information that is acquired. Typically, only the [Ca2+]i as pseudocolor data are displayed, and the localization and intensity of the

S-1–Based Chemoradiotherapy Followed by Consolidation Chemotherapy With S-1 in Elderly Patients With Esophageal Squamous Cell Carcinoma: A Multicenter Phase II Trial

Frontiers in Oncology, 2020
Introduction: Intensive treatments can often not be administered to elderly patients with esophageal squamous cell carcinoma (ESCC), leading to a poorer prognosis. This multi-center phase II trial aimed to determine the toxicity profile and efficiency of

Intensity-Modulated Radiotherapy

The Cancer Journal, 2002
Intensity-modulated radiotherapy represents a recent advancement in conformal radiotherapy. It employs specialized computer-driven technology to generate dose distributions that conform to tumor targets with extremely high precision. Treatment planning is based on inverse planning algorithms and iterative computer-driven optimization to generate ...
