Kr. Kendell et al., MR-GUIDED FOCUSED-ULTRASOUND ABLATION SYSTEM - DETERMINATION OF PRECISION AND ACCURACY IN PREPARATION FOR CLINICAL-TRIALS, Radiology, 209(3), 1998, pp. 856-861
The authors analyzed the accuracy and precision of focal-spot placemen
t with a magnetic resonance-guided, focused-ultrasound system. Average
absolute accuracy errors ranged from 0.2 to 1.0 mm, and average absol
ute individual precision errors ranged from 0.2 to 0.3 mm. To prevent
damage to vital structures, single sonications and sonication grids sh
ould be placed beyond approximately 2 and 1 mm, respectively.
