Podrobná analýza odezvy různých buněčných linií na ozařování ionty uhlíku
Hromčíková, Hana ; Kundrát, Pavel ; Lokajíček st., Miloš
Cell survival data of three Chinese hamster cell lines irradiated by carbon ions have been analyzed on the basis of the probabilistic two-stage model. Detailed characteristics of damage induction and repair-success probabilities have been established, quantifying the difference in response to carbon irradiation between these cell lines.
Energie předávaná ionizujícími částicemi a inaktivační mechanismus v buňkách
Kundrát, Pavel ; Lokajíček st., Miloš
Energy loss of individual particles, their lateral scattering and energy-loss straggling are involved in the Bragg peak formation. A model of the Bragg peak of protons and light ions is presented that takes into account all these phenomena.
Pravděpodobnostní model popisující inaktivaci buněk ionizujícími částicemi
Kundrát, Pavel
Numerical analysis of experimental data concerning cell inactivaton by protons is presented, showing feasibility of the general probabilistic model of cell inactivation proposed by Judas and Lokajíček (2001), which enables one to respect even the detailed sructure of cell survival curves. Problems of corresponding numerical calculation are discused in details.
On the use of accelerated hadrons in treatment of cancer
Kundrát, Pavel ; Lokajíček st., Miloš
Basic principles of hadron radiotherpy and its current use worldwide will be summarized. Situation in the Czech Republic will be discussed, too
Mathematical moddeling of radiobiological mechanism in cells
Lokajíček st., Miloš ; Kundrát, Pavel
A mathematical model will be presented thet enables to correlate the inactivation effect of defined numbers of ionizing particles traversing cell nuclei with corresponding cell survival curves. Applications of the given model in analyzing the relative biological efficiency of protons and ions in their Bragg peak regions will be discussed
