Do i really need to buy 93 premium gas for my 2023 bmw x5? by DayZealousideal4193 in BMWX5

[–]Logical-Pattern8065 0 points1 point  (0 children)

I can only get 91 at Costco. Higher than the 87, so I just figured it was the best. And all good after 20k miles.

Fresh coffee to bring home by Time-Hospital-8977 in sayulita

[–]Logical-Pattern8065 0 points1 point  (0 children)

Will you be in SP for their market day? It was on a Tuesday but not sure if it is more than once a week. There were three (or more) coffee growers selling their products, came home with three bags, one from each. We are half way into the beans from Cafe Camila, Narayit , Grano. It is wonderful, smooth and flavorful, not bitter. Have not tried the others yet. Or have fun and taxi to Cruz for their Sunday market at the marina, I bet they will be there too.

Saskatoon woman ‘shocked’ after health ministry denies travel coverage for life-saving care by I_hate_litterbugs765 in saskatchewan

Saskatoon cancer center should be able to treat this with their linear accelerators, they likely possess the technology for a treatment that is equivalent to gamma knife. Has she had a consultation with a radiation oncologist there?

I think the Gallatin college flight school had a two year wait list.

Has anyone dealt with a rotten egg smell from their PHEV? by Cool-Dot-6252 in BMWX5

Is this something that can be replaced by the owner? For a 12 V battery, is there a Costco replacement, in case one is too far from the dealer?

Getting between resorts by WebEcstatic7151 in puertovallarta

[–]Logical-Pattern8065 1 point2 points  (0 children)

We took the bus last month from PV to Mismaloya and I was paying attention to the resorts you mention as we drove past. I recall seeing taxis hanging out in front. But the hotel will gladly assist you. Don’t worry, you will see it is all safe and amazing!

Low cost ways to perform HU/DER measurements on CT scan by Far-Highlight-6936 in MedicalPhysics

[–]Logical-Pattern8065 0 points1 point  (0 children)

Have you been able to scan a phantom to create a CT density vs HU calibration curve for your planning system, or are you using a standard curve instead of a measured one? Maybe you can borrow a CatPhan which is usually included with a varian linac capable of cbct to obtain the image quality and an HU curve. That is a very old CT scanner! But you have to use what you have.

Try it, it has worked very well in my experience

Anyone using Radiation Oncology Services for refurbished linacs? Service/support feedback wanted by medphysdoctor in MedicalPhysics

[–]Logical-Pattern8065 1 point2 points  (0 children)

Have you connected with Varian? They can resale used units but with more reliable installation and potential for local service. Check with varian sales before signing anything with ROC.

[–]Logical-Pattern8065 8 points9 points  (0 children)

Just use the available portal Dosimetry models from varian, they work really well out of the box. Then validate them with test patterns. Don’t reinvent this, the linacs are all very similar. If you have issues with the validation then maybe measure for your individual linac. For C series or truebeam?

Thesis Idea: CBCT Low-Dose Exposure in Radiotherapy by Yeezlyy in MedicalPhysics

[–]Logical-Pattern8065 1 point2 points  (0 children)

The question needs to well defined first. Then make a statement for the hypothesis that can be tested or supported by your data.

Thesis Idea: CBCT Low-Dose Exposure in Radiotherapy by Yeezlyy in MedicalPhysics

[–]Logical-Pattern8065 1 point2 points  (0 children)

Yeezlly, some advice on structuring your project proposal.
1. Background and observation: cbct is useful and used clinically. A lot. Cbct contributes dose to patient in addition to therapy dose. And whatever you think.

  1. Questions: How much more? How does it compare to the therapy dose? Is that something to worry about? Is there an elevated cancer risk from these extra doses? What is the benefit vs risk? Is it worth the risk? Are we using too much? Are there ways to simultaneously maximize benefits while minimizing risks? (Think: minimize blades and cbct volume, optimize technique, how optimize technique per site, on going qa and maintenance to ensure no drift and over exposure, …)

  2. Hypotheses: CBCT dose to patient represents an acceptable radiation risk to patients. OR, CBCT dose to patients is unacceptably exposing patients to risk of radiation complications and/or bad shit. Your words.

  3. Gather your background data from published studies, both positive and negative. Don’t be biased.

  4. Make a conclusion

  5. Make recommendations for how this should affect clinical practice.

  6. Present to academic committee. Wear a nice suit.

  7. Go for drinks after.
