A planning apparatus (70) determines irradiation parameter data (67) for a charged particle irradiation system (1), which radiates charged particles generated by an ion source (2) to a target (80) by accelerating the charged particles by means of a linear accelerator (4) and a synchrotron (5). The planning apparatus is provided with: a planning program (73), which determines the irradiation parameter data (67) with respect to one target (80) by combining charged particles of a plurality of kinds of ion species; and a CPU (71) for executing the planning program. Consequently, the irradiation planning apparatus capable of performing irradiation with desirable dose distribution with respect to the target, the irradiation planning program, an irradiation plan determining method, and the charged particle irradiation system are provided.

Systems and methods monitoring progress of procedures by radiation exposure are provided. Position data is received for an equipment item used for the procedure and configured to produce radiation (“radiation device”). Position data is received from the tracking device during the procedure. An estimated exposure level is determined by a controller for the individual based, at least in part, on the position data from the tracking device relative to the position data from the radiation device and compared to a benchmark. If the estimated exposure level for the individual exceeds the benchmark, an electronic notification is generated.

A respiratory gating phantom device includes a first airbag, a second airbag, a first catheter, a second catheter, a fixture, and an air pressure gating device. The first catheter and the second catheter are respectively installed in the first airbag and the second airbag. The fixture is provided with a phantom tumor and adjustably installed in the first catheter or the second catheter, thereby installing the phantom tumor in the first catheter or the second catheter. The air pressure gating device, connected to the first airbag and the second airbag, inflates and deflates the first airbag and the second airbag to simulate breathing. The first catheter and the second catheter respectively move along three-dimensional direction and two-dimensional direction in response to motions of the first airbag and the second airbag.

Disclosed herein are systems, methods, and computer-readable storage devices for manufacturing patient-specific bolus for use in targeted radiotherapy treatment. Based on dose calculations without a bolus and based on three-dimensional scan data of a patient, the example system generates a model of a bolus for targeting radiotherapy treatment to a planning target volume or target region within the patient. The system can perform several iterations to generate a resulting model for the bolus. Then, the system can generate instructions for controlling a three-dimensional printer to generate the bolus that conforms to the patient's skin surface while also specifically targeting the planning target volume for the radiotherapy treatment. In this way, the amount of radiotherapy treatment administered to other tissue is reduced, while the costs, time, and human involvement in creating the bolus are significantly reduced.
