Fig.6.1.Techniques of the reconstruction of two-dimensional thyroid image on the base of lobe height, depth and width parameters. Echograms of the fore-part of the neck and their schematic representations. Scale 1:1. The figure includes sections No. 2, 3, 5, 6, 8, 9, 10, 12, 13. To reconstruct a two-dimensional thyroid image it is necessary to measure the thyroid lobe height, depth and width at each transverse section performed. Scanning step and number of transverse sections are taken into account. See Fig. 6.1, 6.2.
Fig.6.2. Reconstructed two-dimensional images of the thyroid gland. Normal. A - right lateral view - projection on the sagittal plane. B - anterior view - projection on the frontal plane. C - posterior view - projection on the fron-tal plane. The images are 70% of the scale 1:1. Horizontal lines in fig.6.2.B show the level of transverse section. Num-bers in rectangular frame indicate the sections included in fig.6.2. Signs. 1 - musculus constrictor pharyngis inferior, 2 - cartilago thyroidea, 3 - cartilago cricoidea, 4 - glandula thyroidea, lobus dexter, 5 - oesophagus, 6 - vertebra, 7 - trachea.
