title: Some DSA testing methods and an evaluation of eight available units.
abstract: Eight DSA units in the Sydney region were evaluated by a set of simple performance tests. Low contrast resolution and iodine sensitivity tests exhibited the most variation between the six fully tested units. A range of performance levels was measured. Four of the eight units required adjustment by the manufacturers' service engineer after testing. The evaluation of those units considered satisfactory by both the manufacturers and the operators indicated that the fully interfaced, integral units gave better results than the earlier 'add on' units.
