Introduction Proton therapy is the most advanced radiotherapeutic technique. For the same dose in the tumor, the dose in the surrounding normal tissue is substantially lower than in classical radiation therapy using photon beams. Protons stop in the

Combining CO2 sequestration and CH4 production by means of guest exchange in a gas hydrate reservoir: two pilot scale experiments

Autor: Heeschen, K., Spangenberg, E., Schicks, J., Deusner, C., Priegnitz, M., Beeskow-Strauch, B., Bigalke, N., Luzi-Helbing, M., Kossel, E., Haeckel, M., Wang, Y.

Methane (CH4) hydrates are considered as a player in the field of energy supply and – if applied as such – as a possible sink for the greenhouse gas carbon dioxide (CO2). Next to the more conventional production methods depressurization and therm

Sensitivity of a prompt-gamma slit-camera to detect range shifts for proton treatment verification

Autor: Nenoff, L., Priegnitz, M., Janssens, G., Petzoldt, J., Trezza, A., Smeets, J., Pausch, G., Richter, C.

Publikováno v: Radiotherapy and Oncology 125(2017)3, 534-540

Background and Purpose: Prompt-gamma imaging (PGI) was recently applied successfully in first clinical patient treatments in pencil beam scanning (PBS) and double scattering (DS). Still, systematic evaluations on its capability in clinical conditions

Requirements for a Compton camera for in-vivo range verification of proton therapy

Autor: Rohling, H., Priegnitz, M., Schöne, S., Schumann, A., Enghardt, W., Hueso-Gonzalez, F., Pausch, G., Fiedler, F.

Publikováno v: Physics in Medicine and Biology 62(2017)7, 2795-2811

To ensure the optimal outcome of proton therapy, in-vivo range verification is highly desired. Prompt gamma-ray imaging (PGI) is a possible approach for in-vivo range monitoring. For PGI dedicated detection systems, e.g. Compton cameras, are currentl

Publikováno v: Geophysical Research Abstracts

Natural gas hydrates occur at all active and passive continental margins, in permafrost regions, and deep lakes. Since they are supposed to contain enormous amounts of methane, gas hydrates are discussed as an energy resource. For the production of g

Purpose The dose distribution and range of proton beams are exceedingly prone to uncertainties and anatomical changes, demanding for an in-vivo range verification. A promising approach is prompt γ-ray imaging (PGI), which was recently implemented cl

Publikováno v: Physics in Medicine and Biology 61(2016)2, N20-N34

Particle therapy positron emission tomography (PT-PET) is an in vivo and non-invasive imaging technique to monitor treatment delivery in particle therapy. The inevitable patient respiratory motion during irradiation causes artefacts and inaccurate ac
