• Aproksymacja zmian stężenia znacznika w badaniach pCT płuc

  Publication

  • M. Browarczyk
  • R. Kalicka

  - Year 2012

  W artykule zaproponowano nową metodę aproksymacji zmian stężenia znacznika w badaniach pCT płuc. Zmiany stężenia znacznika są skanowane z częstotliwością kilkakrotnie większą niż częstotliwość oddechu. Metoda opiera się na spostrzeżeniu, że częstotliwość występowania pików na krzywych zmian stężenia znacznika jest równa częstotliwości oddechu badanego. Zaprezentowano przykładowe dopasowanie funkcji regresji w postaci krzywej Gaussa...
