For that purpose, a system to measure K in brain is being developed. Our specific aim is to assess the potential contribution to the K photopeak from cranial K located outside the brain. For this, a simplified spherical phantom to represent the brain, a square box to represent the cranium, and a K point source to assess the contributions due to K outside the brain were used. It is estimated that only about 1-2% of the K photopeak might be attributable to K outside the brain.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":211,"end":216},"obj":"HP_0000969"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubmedHPO","color":"#99ec93","default":true}]}]}}
