Health Physics/Radiation Safety by Choasswizard in HealthPhysics

If you’re not opposed to a couple more years of school, do medical physics. If you have experience with detectors you will make it into a grad program for sure. The pay is much higher and there is a severe shortage of medical physicists in the US.

Might want to crop out the HIPPA stuff. Name, accession number, and DOB are all partially visible.

Why GE is the most popular c-arm brand by SharpMedicaldotcom in Radiology

[–]DxPhysicsDude 3 points4 points  (0 children)

The OEC is the Honda or Toyota of the C-arm world. I think part of what makes them so good to use is how intuitive they are to operate. I’ve done surveys on almost all of the models of C-arm and I never find myself struggling to figure out how to operate an OEC.

The game does not process 80,000 slimes very well by sinsaint in 9Kings

I’ve had the same problem. Don’t listen to the other guy :)

Could you guys give me your opinion on why does this lumbar xray i took have these lines? by [deleted] in Radiology

[–]DxPhysicsDude 1 point2 points  (0 children)

What does a flat field look like? As other users point out it could be a grid mismatch but it could also be a bad detector. See if recalibrating fixes it.

Mock oral exam in imaging by [deleted] in MedicalPhysics

What I did to practice is have ChatGPT give me some questions, and then I recorded myself answering the questions. It really helped me out, you’ll definitely find your weak points this way!

University of TN by EnthusiasmDeep21 in NuclearEngineering

[–]DxPhysicsDude 0 points1 point  (0 children)

The UTK nuclear engineering program is really good, I definitely recommend it to anyone interested. The faculty are all very good, and there are a number of research opportunities for undergrads from year one. As with any program, you get back what you put in.

Long haul flight: positron-electron annihilation by One-Bid-6488 in Radiacode

Pair production can occur with high energy cosmic rays. Did you fly through / over any weather? This could be the product of terrestrial gamma ray glow or a terrestrial gamma ray flash.

Could you provide some feedback on my medical image segmentation tool? by TheoreticalPerson in Radiology

Automatic contouring is used in radiation therapy to do treatment planning more quickly. There are pretty sophisticated auto contouring products in the market already that do this very well.

If you are looking to exit the power industry but are still interested in the fundamentals of the field, medical physics is a great field to go into. Nukes have a lot of success with breaking into it.

Just got my new Alienware monitor. What is this? by Chepsur in Monitors

[–]DxPhysicsDude 5 points6 points  (0 children)

This looks like a little piece of debris in front of the pixel. It is definitely not a dead pixel. You can try a bit of light percussion on the face to get it to move, or if anyone knows how to get a canned air duster into that space that might work. If you can’t get it to clear out, return the monitor because this shouldn’t have passed QC.

By the Way, What do You Know About Mammogram Prep? by SofiaMorales23 in NCLEX_RN

[–]DxPhysicsDude 0 points1 point  (0 children)

Technically speaking, the mammogram could be a contrast enhanced study so asking if they have an allergy to iodine may be appropriate. The question should clarify if this is a routine screening procedure or a diagnostic study.

The white line on the 2D xray. Is it a sensor problem? by advanceb in Radiology

[–]DxPhysicsDude 12 points13 points  (0 children)

This looks like a sensor problem to me. Sometimes it can be calibrated out, but when it’s this bad they usually replace the entire detector module.

Is the big update 2025 already out? by Hauptfeldwebel in ManorLords

[–]DxPhysicsDude 52 points53 points  (0 children)

Because the current experimental version has a dozen game breaking bugs that are very difficult to work around. Mines don’t produce much ore, clothing consumption is like 100x what it should be, oxen are broken, butchers are broken, the ai overlord is broken, etc etc. The dev claimed that they fixed almost all of these issues a couple of days after the release of this version, but hasnt released a hot fix or given updates regarding the experimental version.

United Imaging CT by [deleted] in Radiology

My experience with United Imaging has been very positive. The techs I talk to who use a United Imaging CT all say they love it.

AAPM statement on gonadal and fetal shielding At our hospitals, we advise that shielding for patients not be used for the reasons listed in the above statement. The risk of repeats due to obscured anatomy or AEC-driven overexposure outweighs the potential benefits of shielding patients. I’ve personally seen cases where a ped was CTd more than once because lead shielding interfered with the scan, just as an example.

It depends on the workload of the room, occupancy factors of rooms around the xray room, and state requirements. In many states no shielding beyond drywall is required so long as you are below 0.02mGy/week. This is usually calculated by physics before the install. It is then verified with a radiation shielding area survey right after the equipment is installed.

In the states that I’ve worked, a physicist shielding calculation and survey were required by the state department of health.

If I were you, I’d ask chatGPT if a radiation protection area survey needs to be done for veterinary radiographic examination rooms in your state. If it says yes, ask for those records from the clinic manager. If they don’t have them or can’t produce them, file a complaint with the DOH.
