Apparatus, consisting of an envelope transparent to X-rays, and a fluid transparent to X-rays and contained within the envelope. Multiple charged particles, opaque to X-rays, are suspended within the fluid. There are at least two electrodes on opposite sides of the envelope, that are configured to apply a field to the multiple particles, so that, absent the field, the particles disperse throughout the fluid. 2762666vl coo cvIt co C)l, C/j C/j CY) |
