introduction: renal length as measured on sonography is fundamental in diagnosis & follow up of renal diseases, and there’s increasing use of this kind of examination nowadays. some radiologists believe in the effect of position on renal measurements. regarding the above mentioned facts and in order to compare effect of patient position on sonographic measurement of renal length, this study was...
We prove an uncertainty relation, which imposes a bound on any joint measurement of position and momentum. It is of the form (∆P )(∆Q) ≥ C~, where the ‘uncertainties’ quantify the difference between the marginals of the joint measurement and the corresponding ideal observable. Applied to an approximate position measurement followed by a momentum measurement, the uncertainties become the precisi...
Background: Sonography is used for measuring the muscle morphology including length, depth, cross-sectional area, bulk and pennation angle. The supraspinatus is the most common affected muscle among the rotator cuff muscles. There is no study about the reliability of sonographic measurement of supraspinatus thickness in the positions of empty can (EC), full can (FC) and hug up (HU) tests. The p...
