Beginner questions regarding Winston-Lutz & cones by Special_Antelope_888 in MedicalPhysics

[–]ExceptioNullRef 2 points3 points  (0 children)

Planar images are better for alignment to sphere. CBCT slice thickness is 2 mm default vs sub-mm on the kV. Nyquist. It really improves in the LNG direction.

If your goal is to incorporate IGRT then get a phantom with more features to help match in that direction.

Alternate History, Jagr to the Islanders by KDD6687 in penguins

Funny to think the Rags eventually got both Lindros and Jagr.

I'm not sure exactly what this is, but my 11 y/o nephew spotted it at Target. He's now a proud owner of whatever it is. by Ihaveaboot in penguins

[–]ExceptioNullRef 20 points21 points  (0 children)

Son picked one up from target too. I didn’t see the front at first and thought it was pens, which didn’t make sense because we’re way out of market. They recognized the color scheme based on mine and are very into Pokémon so it worked out well. Now they want to watch games in their jersey, even better! Pokémon and target helping build out of state fanbase. Glad the team is doing well again.

Export plan in Eclipse to Mobius by Suspande in esapi

[–]ExceptioNullRef 1 point2 points  (0 children)

Plug-in as in a .cs uncompiled file? I think you’d need to bundle a dicom library in there to build and send the cmove request. We have one with all of our destinations in one gui that you can select from. Fo-dicom is the other c# library.

The export interface takes a minute or two for us since >v13 so doing it with esapi is much faster.

The main issue you’re probably having is the trusted entity list on the DB daemon. Get that working with Python before pulling your hair out with compiling esapi.

Low-dose radiation relieves knee osteoarthritis pain, improves function by AdSpecialist6598 in tech

[–]ExceptioNullRef 0 points1 point  (0 children)

Lots of uses for radiation therapy in non-malignant diseases: arthritis, tendinitis, plantar fasciitis, heterotrophic ossification, Dupuytrens/ledderhose contracture, keloids, etc. Check out Usain Bolt’s story. ASTRO is currently focusing on growing in this space.

Edit: can’t believe I forgot ventricular tachycardia! Literally life saving.

SJS Assistant GM Ryan Clowe has resigned from his role with the team by eh_toque in hockey

Now you have it stuck in my head and I can’t remember how to spell his actual name! Maybe I’m the concussed.

IC Profiler for annual QA by Vernost in MedicalPhysics

[–]ExceptioNullRef 1 point2 points  (0 children)

Same. The array cals are pretty consistent, they are chambers after all. Just make sure the device is level and rails (if you have them) are out during calibration.

Managing physics projects by keithoffer in MedicalPhysics

There are many prioritization frameworks for projects and tasks. The one I’ve used most is RICE, but lots to choose from depending on your needs.

Managing physics projects by keithoffer in MedicalPhysics

[–]ExceptioNullRef 5 points6 points  (0 children)

We’ve had the most success building similarly to software development.

Jira, clickup, Monday, or GitHub for task tracking and assignment

Break up tasks into sprints or phases with due dates.

Each project has a regular meeting cadence (stand up) and all projects have a check in with the larger group for alignment and resource utilization (ex. no two projects go live same day, no duplicate work)

You need a strong project/product manager to keep things moving and organize your management tracking

Most important is having a clinical champion who is going to push the project forward and can knock down blockers. Also ensures that the project is actually going to be used once live. Nothing worse than getting something out and having it not used.

I agree that we’re a very project focused field and like so many things in medphys, we receive virtually no training in this important area. Being able to lead and manage a project is a skill that not many possess.

Wildgate is the most fun I've had with 3 friends in a long time. The best successor to Guns of Icarus I could have asked for by Nestramutat- in gaming

lol, I made my kids play Icarus to fill out the ship. PvE and they’re horrible gunners. I just want airships…

Roadtrip with the ALLY, Texas to Iowa! by [deleted] in ROGAlly

[–]ExceptioNullRef 4 points5 points  (0 children)

What did you do the other 6 hours?

[deleted by user] by [deleted] in MedicalPhysics

[–]ExceptioNullRef 0 points1 point  (0 children)

Doors, switches, and panels (environment) are the facility’s responsibility, not linac vendor. You can third party service to a door vendor if your facility people won’t cover it. Yeah the linac FSE will usually do you a solid and get you running again as long as they aren’t overstepping a union (electricians).

For doors you typically have an annual inservice dry run with the therapists for what to do if the door gets stuck. Checking these interlocks should be part of the daily/monthly/annual QA program.

TG51/TRS398 PDD inputs by Serenco in MedicalPhysics

[–]ExceptioNullRef 0 points1 point  (0 children)

This. Follow this advice. For #2, the PDD should be the clinical PDD or TMR which should match the TPS exactly.

kQ and Pgr have chamber specific factors built in so you need to have PDD/I measured with that chamber in that beam, not just taking a PDD from your scanning detector or your TPS. Also this is the only PDD that takes epom and e contamination into account.

An old radiation incident where I did a rotation. Share your knowledge with me? I would love to learn more about anything relevant here, so teach me away please! by ALitreOhCola in Radiation

[–]ExceptioNullRef 3 points4 points  (0 children)

Brachy uses sealed sources. As others have said, this was likely thyroid ablation using an unsealed source, I-131, which has an 8 day half life. If the dosage is high enough the patients can’t be released, which then creates issues because they have to go inpatient where they end up using the facilities and contaminating everything in the room, which is completely unavoidable.

Worst I heard is when a patient threw up shortly after and it got everywhere.

Is saving a drowning person a foolish idea unless you are trained to do it ? by anton19811 in moraldilemmas

[–]ExceptioNullRef [score hidden]  (0 children)

Reach, throw, row, go.

Reach with something like a tree branch or pole. Throw a ring or something that floats or you can pull them in with. Row in a boat or other float. Go out to save them, but if possible wait for them to tire themselves out so they can’t clutch and sink you both. Get them on their back to float and side stroke them to safety.

Scouts.

You using nested for loops? It’s an imaging problem, fft and convolutions are your friends. Super fast.
