attenuation c. time-gain c
depth c. time-gain c
gene dosage c. the putative mechanism that adjusts the X-linked phenotypes of males and females to compensate for the haploid state in males and the diploid state in females. It is now largely ascribed to lyonization which compensates the mean of the dose but not its variance, which is greater in females.
time-gain c. (TGC) in ultrasonography, an increase in receiver gain with time to compensate for loss in echo amplitude with depth, usually due to attenuation.attenuation c., depth c., time compensation gain, time-compensated gain, time-varied gain control, time-varied gain;
