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, shape of quadrate lobe (QL) was quadrangular in 85%, followed by a rectangular shape in 10%.
The middle lobe described by Wagner corresponds to the right and left medial lobes and the quadrate lobe. According to Wagner the middle lobe was the largest, and here we coincide since the right and left lobes and the quadrate lobe represent the largest part of the organ.
The fissures on the quadrate lobe were seen in 55.77% of livers examined, whereas Joshi et al (2008) reported an incidence of 20%.
