Abstract: In external beam radiotherapy, 3D scanning water phantoms are the gold standard for obtaining relative dosimetry data. These phantoms, consisting of a water tank and mechanical arm, along with accompanying software, are de-signed to acquire dose profiles along and orthogonal to the beam axis. In brachy-therapy, the acquisition of analogous dose profiles is more difficult, and is generally achieved with complex custom-built phantoms or chemical dosimeters such as film or gel. In this study, a low-cost 3D-printed jig was designed and fabricated within a clinical department, to allow precise brachytherapy dose measurements using a PTW BeamScan water phantom. Specifically, this jig al-lowed applicators to be suspended securely and reproducibly within the water phantom. Protocols were developed to relate the scanning system coordinates to the physical source position, and to obtain isodose planes both parallel and radial to the source axis. The developed solution has the potential to be used for physical verification of TG43 dose calculation parameters (e.g. anisotropy functions), the characterization of dose for a single dwell position in a complex applicator containing non-water equivalent materials, or the collection of point dose measure-ments for treatments incorporating multiple dwell positions or catheters.

As much as I've loved to hate on it, the CCRU as a subject inevitably interests me from time to time, and I've gained from critically drinking in it's aesthetically pleasing side. I recently learned of this website where you can play Decadence and Subdecadence from their mythology https://playdecadence.online

Mitsprache im Altersheim: Wengistein macht gute Erfahrungen mit Bewohnerrat
Pflegeheime standen vor dem Dilemma zwischen Schutz und Schaden für Bewohnende. Diese sollen sich künftig einbringen.

In a 6-3 decision on Tuesday, the Supreme Court ruled that immigration officers may consider pending criminal charges when weighing whether or not to readmit green card holders into the United States. 
"Lawful permanent residents generally must be regarded as already admitted to the country and usually do not have to reapply for admission when they return from temporary overseas travel," the Supreme Court explained.
"Under an exception, the Government may regard a …

Absurd plan. Bij een pandemie met een virus met een IFR van 30% hebben de kinderen die het overleven een aardige kans om wees te worden. Maar ze konden naar school hoor!
Echt, wie dit bedenkt is niet goed wijs.

Sluit nooit meer scholen, zeggen onderwijsorganisaties: 'Impact is niet te onderschatten'
Scholen zouden tijdens een toekomstige crisis niet opnieuw moeten worden gesloten. Daartoe roepen onderwijsorganisaties op bij RTL Nieuws, zes jaar na het begin van de coronapandemie. Veel leerlingen hebben in die tijd last gehad van leerachterstanden en mentale problemen zoals eenzaamheid. De gevolgen daarvan zijn nog steeds voelbaar.

I had some hopes. John Healey has shattered them
John Healey’s appointment as Chancellor surprised many people, me included. The biggest reason for surprise was that he has no record as an economic thinker. As I noted on Monday evening, he might have spent time in the Treasury under Tony Blair and Gordon Brown, but since then he has shown...

Promising lower costs, higher speeds, and the Los Angeles Dodgers,
Charter Communications CEO Chris Winfrey announced on Thursday
the finalization of a long-pending acquisition of Cox Communications,
for a reported $34.5 billion.
The deal affects six million Cox customers,
who Winfrey said would initially see no differences in their billing.
However, within 18 months, they would gain entirely U.S.-based customer service.
“Customers will see no chang…

Cox Communications, Santa Barbara’s Sole Cable Provider, Officially Acquired by Spectrum-Owner Charter
Charter CEO says $34.5 billion deal will bring lower costs, higher speeds, and the Los Angeles Dodgers to Cox’s six million customers.
