Abstract: Disclosed is a method of: providing a mixture of a polymer or a resin and a transition metal compound, producing a fiber from the mixture, and heating the fiber under conditions effective to form a carbon nanotube-containing carbonaceous fiber. The polymer or resin is an aromatic polymer or a precursor thereof and the mixture is a neat mixture or is combined with a solvent. Also disclosed are a carbonaceous fiber or carbonaceous nanofiber sheet having at least 15 wt. % carbon nanotubes, a fiber or nanofiber sheet having the a polymer or a resin and the transition metal compound, and a fiber or nanofiber sheet having an aromatic polymer and metal nanoparticles.

Abstract: A method and an apparatus for dose-guided radiotherapy for a patient (P) having an identified radiotherapy target utilizes a radiation detecting array (R) of radiation-sensitive dosimeters for the real-time remote measurement of radiotherapy at the radiation detecting array (R). The radiation detecting array is positioned within the patient's (P) body along the treatment path before or after the identified radiotherapy target or the device may be positioned beyond the patient (P) to measure transit dose. A radiation source (A) for emitting radiation for radiotherapy along a treatment path through the patient (P) to the identified radiotherapy target is utilized. The method includes generating a predicted dose pattern of radiation at the placed radiation detecting array (R). The predicted dose pattern assumes an on-target radiation source (A) emitting the radiotherapy beam along the treatment path through the patient (P) to the identified radiotherapy target.
