Artificial Intelligence-Empowered Multistep Integrated Radiation Therapy Workflow for Nasopharyngeal Carcinoma.

Purpose: To establish an artificial intelligence (AI)-empowered multistep integrated (MSI) radiation therapy (RT) workflow for patients with nasopharyngeal carcinoma (NPC) and evaluate its feasibility and clinical performance.

Methods And Materials: Patients with NPC scheduled for MSI RT workflow were prospectively enrolled. This workflow integrates RT procedures from computed tomography (CT) scan to beam delivery, all performed with the patient on the treatment couch.

Pharyngeal wall floppiness: a novel technique to detect upper airway collapsibility in patients with OSAS.

Objective: To measure pharyngeal wall floppiness (PWF) under different pressures, a novel method and technique were introduced in the present study.

Study Design: A prospective clinical study.

Subjects And Methods: Forty-seven healthy subjects (32 male; mean age, 37.
