A new principle used for determining liver volume by means of ultrasonic scanning is described. Based upon a single transverse and a series of longitudinal scanning sections through the liver a model of the organ is defined. The outline of the liver in each scanning section is registered by means of an electronic Pencilfollower D-Mac Co. Ltd., Glasgow (U.K) and the calculations are carried out by a computer, which is connected directly with the Pencilfollower. The precision of the method was tested in an autopsy series. The standard deviation on the differences between calculated and real liver volumes was 168 ml. The reproducibility of the method was tested in double determinations on 15 female and 15 male subjects without actual or previous diseases of the liver, biliary tract, kidneys or heart. The standard deviation for a single measurement was for females 67 ml. and for the males 41 ml. It is concluded that the method makes it possible to obtain important information in the diagnosis of dise...
