Abstract
A portable miniature ultrasonic transducer positioning apparatus is described having a transducer receiving sleeve coupled to a pair of orthogonally orientated, independently pivotable yokes. The yokes are pivotably mounted to a base member the under surface of which is fitted with a non-skid rubber cap. A pair of potentiometers are coupled to the axes of the yokes and to a dual meter sleeve position indicator for indicating, with respect to the axes of the yokes, the angular position of a probe slidably fitted in the sleeve. An oscilloscope or similar signal display device is coupled to the probe for providing signal readout from the probe for use in ultrasonic cardiology oscilloscope studies. As an option, a ball lever assembly is further provided coupled to the yokes by means of a four-wire cable and wheel assembly for remotely controlling yoke position and the angular position of the sleeve and a probe fitted therein. An emplacement of indelible marks on a patient''s chest corresponding to index marks on the base member, permit, with the use of previously obtained position information from the indicator, accurate positioning of the apparatus during subsequent examinations.
