Abstract

Группа изобретений относится к медицине, а именно к способам и системам анализа коллатерального потока. Способ включает в себя получение показателей первого притока и первой перфузии для нездоровой представляющей интерес ткани, получение показателей второго притока и второй перфузии для здоровой представляющей интерес ткани, и одновременное представление показателей первого потока и перфузии для нездоровой представляющей интерес ткани и показателей второго потока и перфузии для здоровой представляющей интерес ткани. Система включает в себя устройство дополнения данных визуализации, выполненное с возможностью дополнения данных визуализации нездоровой представляющей интерес ткани и здоровой представляющей интерес ткани показателям притока и перфузии для нездоровой и здоровой представляющей интерес ткани. Система также включает в себя определитель оценки, выполненный с возможностью формирования сигнала, указывающего коллатеральную классификационную оценку, на основе показателей притока и перфузии. 2 н. и 13 з. п. ф-лы, 3 ил.
