Magnetic resonance imaging-induced forces on video capsule endoscopes: First systematic in vitro assessment

Figure 8 Box plots of magnetically induced displacement force and gravitational force on video capsule endoscopes. A: Magnetically induced displacement force on video capsule endoscopes (VCEs) without (left) and with (right) an integrated permanent magnet; B: Gravity-induced force on VCEs without (left) and with (right) an integrated permanent magnet. The lengths of the boxes mark the 25^th and 75^th percentiles, the yellow lines indicate the 50^th percentile (median), and the whiskers represent the 1.5-fold interquartile range. Note the different scales of the Y-axis in Figure 8A and B.
