lobe

A curve representing the relative signal strength plotted against the position of the aerial with respect to a target. Side lobes are small lobes of energy radiated by radar aerials in diverging directions to the main beam—usually four, two at an angle of 7° from the main beam and two at angle of 90°. Side lobes may cause false weak echoes. An antenna pattern may have just one lobe, or it may have several lobes. Different lobes may have different magnitudes. The strongest lobe is called the main or major lobe. The weak lobes are called secondary or minor lobes.

In the present study, ReHo analysis of the normal elderlies and aMCI patients revealed that in the resting state, ReHo values were significantly higher in the posterior cingulate gyrus, the inner side of the frontal lobe, the inner side cortex of the prefrontal lobe, and part of the parietal lobe.
The thyroid gland abnormality observed in this research were classified into three categories, type I) thyroid gland with right lobe, left lobe, isthmus and pyramidal lobe, type II) thyroid gland with right lobe, left lobe, isthmus and Levator glandulae muscle, and type III) thyroid gland with right lobe, left lobe, isthmus and the co-existing of pyramidal lobe and levator glandulae thyroideae (Table II).
