this reminds me of Intensity-modulated radiation therapy (IMRT) - a treatment of cancer using X-ray beams. because a single beam damages both healthy and cancer tissue alike (and goes through entire body like jedi's lightsaber), IMRT creates many many low dosage beams around the body from different angles. As a result, most of healthy tissue that surrounds tumor gets exposed to a minimum radiation, but cancerous tissue accumulates required x-ray exposure from many small beams.
