doses.Proton patient immobilization needs to reduce patient motion to the largest extent feasible, as is the case with other radiation therapy modalities, but also needs to consider the effect of the immobiliza
It's much easier and safer to look at a broken bone using X-rays than it is to open a patient up. But X-rays can also be harmful. In the early days of X-ray science, a lot of doctors would expose patients and themselves to the beams for long periods of time. Eventually, ...
These machines are much less expensive, costing between $1M and $5M, depending on the model and how good you are at negotiating. Most radiation therapy in the developing world is delivered by cobalt-60 machines. How do they work? Manjit A cobalt-60 machine treats patients using a radio...
“In PBS proton therapy, each layer is delivered in a series of discrete pencil beam spots. The scanning magnets are used to reconfigure the system to deliver dose in the subsequent position,” explains Lee. “This is not an instantaneous process. In the presence of tumour motion due to res...
How much radiation do these machines produce? How does it compare to medical imaging devices? And is it enough to increase cancer rates in the general population? Then there are the questions about privacy. Can TSA agents see bits and pieces they shouldn't be seeing? And do they ever ...
"That was the hardest part for me," he said. "I had so much excitement of wanting to have conversations about football. I've been a big fan of [running back]Antonio Gibson; I wanted to see how he felt about him." Monday Night Pick 'Em ...
In addition, while proteomics operates under the hypothesis that the top-ranking peptide–spectrum match (PSM) is correct, this may not be true for immunopeptidomics where the much larger search space results in more mass ambiguities. Thus, low FDR alone does not sufficiently control for false ...
Once relapse is suspected, it is important to rule out HT to a more aggressive lymphoma particularly if progression occurs within the first 12–24 months after prior therapy (POD12/24). POD12 and POD24 have received much traction in recent years as an indicator of more aggressive disease req...
Unfortunately, in the case of iron, too much of a good thing is not good for you! You really need to initially test your ferritin levels, and then monitor them over time. Additionally, it is often not enough to just eat more iron-rich foods or supplement with iron; many people may al...
This is why we see SIBO so much in our society. It’s really widespread and almost an epidemic. But there’s still not a lot of research out there. SIBO is in the small intestine. Diagnosing it requires a breath test. You’re testing levels of hydrogen and methane gas. The gas in ...
