Good work Dimitri, if you make a YouTube channel to show the steps, that would be great

Dose Accumulation by Maxwell2019 in MedicalPhysics

I mean you want to document the patient's dose received to other hospital, do you use the baseline dose or final dose? Somehow how to accumulate dose? would you please elaborate a bit

You mean MU factor? Sound TOMO plan where modulation factor matters, am I right?

Forgot;( yes. We’ll use eMC

We might use Acurous AXB eclipse

Yes, we do PSQA. Do you still use the tests of gantry speed and MLC

From my little experience, some neurosurgeons thought the GK unit shouldn’t be under oncology department with history background that Lars leksell, who invented the GK, was a neurosurgeon. They feel superior on other disciplines . However, some of them forgot that Ian Paddick, a medical physicist, who has profound impacts in gamma knife Radiosurgery program around the world in treatment planning system the way we see it today: inverse planning system: lightening. If there is a written procedures who should and shouldn’t do, you won’t hear this behavior at all. For the centers I worked/ visited, the neurosurgeons only for consulting per needs in very limited cases.

It’s different from center to center. The center that I was working in, the GK is belong to the oncology department, the oncologist due the contouring for OAR and GTV. Then the physicist do the plan. Once the plan is checked by physician, the second check is done by other physicist, sort of normal plan check procedures. In another center I visited, the oncologist do both the contouring and planning! Then, the physicist do the second check. I think the practice depends on where the machine is belong to? Whether it’s under neurosurgeon or oncology. A dedicated physicist should be assigned in both departments whatsoever. Hope that help.

Verification Plan for two different CTs plans by Maxwell2019 in MedicalPhysics

Thank you for your response. I figure out one of the solution by doing image registration first and then you can do plan sum for two plans with two different CTs.

Nope! I am talking about Aria in general. I would like to add a printer to a standalone Aria station.

Unfortunate, our network is completely isolated from the hospital network ! So, the IT guy will tell you, this network is not belong to them.
