Developing reference plans for evaluating global clinical trials credentialing and PSQA systems

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To develop a practical framework for creating a diverse set of validated reference plans (varying in complexity) and implement a workflow to introduce beam modeling, calibration, and delivery errors into the reference cohort to test and compare various dosimetry audit methodologies.

Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

Historiker als „Mittler zwischen den Welten“? Produktion, Vermittlung und Rezeption historischen Wissens im Zeichen von Citizen Science und Open Science

Heidelberger Jahrbücher Online, 2017
Die Begriffe Citizen Science und Open Science haben in den letzten Jahren einen enormen Bedeutungszuwachs erfahren. Gerade auch von Seiten der Politik werden sie gerne dazu genutzt, ein Feld zu umreißen, auf dem Wissenschaft und Öffentlichkeit einander ...

Cutting the cord [PDF]

The Journal of Cell Biology, 2008
![Graphic][1] Dividing cells that lack Tektin 2 fail to separate. Like parents sending their child off to college, a dividing cell has to let its offspring go. A microtubule-organizing protein helps ensure that the daughter cell breaks free, [Durcan et al.][2] report ...

Spinal Cord Electrophysiology [PDF]

Journal of Visualized Experiments, 2010
The neonatal mouse spinal cord is a model for studying the development of neural circuitries and locomotor movement. We demonstrate the spinal cord dissection and preparation of recording bath artificial cerebrospinal fluid used for locomotor studies. Once dissected, the spinal cord ventral nerve roots can be attached to a recording electrode to record

Demonstration of an enhanced dosing pattern for debulking large and bulky unresectable tumors via differential hole‐size spatially fractionated radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose/objective We propose a novel lattice deployment for spatially fractionated radiotherapy (SFRT) treatments. In this approach, a larger diameter high‐dose sphere is centrally placed in the bulky tumor mass and surrounded by smaller diameter high‐dose spheres.

Comprehensive end‐to‐end dosimetry audit for stereotactic body radiotherapy in spine, lung, and soft tissue

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To create and conduct a comprehensive onsite end‐to‐end dosimetry audit to assess treatment accuracy of spine, lung, and soft tissue Stereotactic Body Radiotherapy (SBRT) across Australian and New Zealand (ANZ) radiotherapy centers. Methods The Australian Clinical Dosimetry Service (ACDS) anthropomorphic thorax phantom underwent a CT ...

A Brain–Spinal Interface Alleviating Gait Deficits after Spinal Cord Injury in Primates

Nature, 2016
Spinal cord injury disrupts the communication between the brain and the spinal circuits that orchestrate movement. To bypass the lesion, brain–computer interfaces have directly linked cortical activity to electrical stimulation of muscles, and have thus ...

Impact of respiratory motion on dose distribution in SIB‐SBRT for lung cancer

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Respiratory motion is a major source of dose uncertainty in lung cancer radiotherapy. The dose distribution of simultaneous integrated boost‐stereotactic body radiotherapy (SIB‐SBRT) is inhomogeneous and is significantly impacted by respiratory motion for lung cancer. The effect of respiratory motion on SIB‐SBRT was investigated with a
