https://doi.org/10.1002/mp.15030 Citations: 50 Sections PDF Tools Share Abstract Small-field dosimetry used in advance treatment technologies poses challenges due to loss of lateral charged particle equilibrium (LCPE), occlusion of the primary photon source, and the limited choice of suitable radi...
The transmittance is normalized to the case where instead of the sample, a cleaned glass is placed on the optical path. Then, the haze is estimated as the power loss. Transmission spectra of samples are measured by a setup shown in Supplementary Fig. S4. The POE sample is placed between ...
Water equivalent path length WEPL Beam hardening 1. Introduction The potential of proton therapy is currently being explored, also for tumour sites influenced by daily variations in anatomy caused e.g. by organ motion or patient positioning and posture changes. However, the proton range is highly...
Open path tunable diode-laser absorption spectroscopy (OP-TDLAS) is a promising technique that is proposed for detecting low concentrations of possible biogenic gases on Mars. This technique determines the concentration of a gas by measuring the amount of laser light absorbed by molecules at a ...
3. The method of claim 2 wherein the method includes the additional steps of: (f) using the displayed image of the anatomy to plan the placement of the radiation-responsive agent, and (g) selecting a treatment path where the reflector will direct therapeutic radiation for exposing the radiati...

A light beam was collimated by a fiber collimator, polarization-selected by a linear polarizer (Thorlabs, LPNIR050-MP2), and focused via an objective lens (Thorlabs, AC254-050-C-ML) onto the FTS, with a diameter of ∼250 μm. Under varying incident angles, a shortwave infrared (SWIR...
Each path is comprised of a cascade of scaled buffer cells based upon the unit cell, as shown in Figure 14b. The driver slice is located adjacent to the switch and takes its input from the MP logic decoder, where the decoders outputs have been pitch-matched to the appropriate input in ...
