Abstract
The disclosure provides systems and methods for generating a treatment plan for irradiating a target region. The system may obtain at least one parameter from the treatment plan. The at least one parameter may relate to a dose region where is enclosed by an isodose curve. The system may obtain an objective function corresponding to the target region. The objective function may represent a conformity between the target region and the dose region. The system may further generate the treatment plan by optimizing the at least one parameter such that the objective function satisfies an optimization condition.
