What happens when you decrease the distance between two foci?
The answer depends on whether they are the foci of an ellipse or a hyperbola.
What happens when you increase the distance between two foci?
-- If they're the foci of a single optical system, then the result can't be stated in general.It depends on the curvatures and relative position of the lenses.-- If they're both the foci of the same ellipse, then the ellipse becomes more eccentric.That is, more squashed and less circular.-- If they're the foci of two parabolas, then there's no relationship between them, andnothing in particular depends on the distance between them.The answer depends on whether they are the foci of an ellipse or a hyperbola.
How many foci does a hyperbola have?
2
Can the foci's of and ellipse be outside the ellipse?
No.
What happen as foci of an ellipse get closer together?
The ellipse will become more circular until it becomes a circle when the two foci coincide.
What is a T2 hyperintense foci?

Why is T2 matter white in the brain?
T2 is seen as a foci of white spots on MRIs of the brain. They are associated with a number of disorders: normal aging, MS, etc.
What does it mean the brain parenchyma shows periventricular T2 hyperintensity and a few scattered subcortical foci of increased T2 and flair signal intensity in the frontal lobes that are nonspecifi?
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
What is Two punctate foci of T2 hyperintensity in the subcortical white matter of the lateral anterior left frontal lobe?
Can hyponatremia cause white matter suggestive of minimal chronic microvascular ischemic change. The grey-white differentiation is maintained. minimal chronic microvascular ischemic on a brain scan?
What if your MRI scanned frontal and parietal white matter T2 hyperintensities what does this mean?
my husband has t2 intense foci in the subcortical white matter in the frontal and parietal reigon these are compatible with foci of chronic ischaemic change the finding is related to small vessel disease his mood swings are getting worse would this disease be a part of mood swings.
What does this mean Scattered foci of T2 FLAIR signal in frontal lobe?
Small foci of hyper intense signal on T2 weighted images are common in the brain parenchyma, more often in the cerebral hemispheres. They are so common, that merely identifying one or a few is usually of no clinical consequence without additional signs on the MRI scan.
What is the foci of an eclipse?
The foci of an eclipse is 2.
How many foci does the graph of a hyperbola have?
Two foci's are found on a hyperbola graph.

What is sounnd foci?
The point where sound waves come together (foci).
What does this mean Scatterd foci of T2 FLAIR signal hyperintensity in the periventricular deep and subcortical white matter?
The above includes what was the first line written under "impressions" on my radiology report related to an MRI done w/o and with Contrast which I was given recently. I'm going to see my neurologist today, but can tell you what I know now. The doctors I've spoken with so far expressed concern, then some calming words such as, "the report wasn't conclusive," as the radiologist had included a number of possible reasons for the results. However, I've since read the fact I had an MRI six years ago during which this foci was not present, this presents a problem. The fact the foci is in the periventricular area typically suggests a diagnosis of Multiple Sclerosis. However, my neurologist ask to look at the films himself, to confirm this foci or lesion, is new. If it is indeed a new lesion, this signifies a diagnosis of either Multiple Sclerosis or another demyelinating disease. (Note: I had a "small foci" of "abnormal T2 Flair" rather than being scattered. )
