Title:
放射線照射方法と放射線照射装置
Document Type and Number:
Japanese Patent JP4188501
Kind Code:
B2
Abstract:
Method and system aspects for achieving more accurate radiation delivery during radiation treatment by a radiation-emitting system are described. In a method aspect, and system for achieving same, the method includes providing a table of dose rate values for accumulated dosages in a treatment unit of the radiation emitting system, and controlling a dose rate of radiation emitted from the radiation emitting system through utilization of the table of dose rates. Controlling further includes determining an accumulated dosage at a sampling point, and comparing the accumulated dosage to a total desired dosage. The dose rate is adjusted based on the table of dose rate values and the determined accumulated dosage, with the dose rate ramped down as the accumulated dosage nears the total desired dosage. Accumulated dosages include fractional numbers of monitor units.
