[Nutritional management of patients with head and neck cancer treated with radiation]. / Prise en charge nutritionnelle des patients atteints de cancer de la tête et du cou traité par irradiation.

Radiotherapy and chemotherapy are standard treatment of head and neck cancer alone or associated to surgical treatment. Early (during treatment or the following weeks) and late side effects contribute to malnutrition in this population at risk. In this context, nutritional support adapted by dietary monitoring and enteral nutrition (nasogastric tube or gastrostomy) are often necessary. The early identification of the patients with high malnutrition risk and requiring enteral nutrition is necessary to improve the tolerance and efficacy of treatment.

Unified statistically independent region processor for deterministic and fluctuating targets in nonoverlapping background.

Recently, new approaches for location of a target in nonoverlapping noise, which are optimal in the maximum-likelihood sense, have been proposed. In particular, different methods for deterministic or fluctuating targets have been developed. We propose a unified and optimal processor for a target with either known or unknown gray levels. We demonstrate the efficiency and robustness of this method in comparison with previously developed processors.

Optimal X(2) filtering method and application to targets and backgrounds with random correlated gray levels.

We describe a pattern recognition processor based on a new optimal x(2) filtering method that is designed to localize a target with unknown gray levels appearing on a random background. This processor consists of preprocessing of the analyzed image followed by correlations with binary masks.
