Abstract: A method of altering cells comprising culturing them in a growth factor gradient, wherein said gradient is provided by a polyhedra delivery system (PODS) that releases the growth factor to set up the gradient.

Abstract: The invention provides a patient shuttle system and an irradiation system for particle therapy. A patient shuttle system of one embodiment of the invention includes: a patient table (110) adapted to carry a patient; a patient table drive unit (120) that moves and/or rotates the patient table; and a transfer unit (130) having a base (131) on which the patient table drive unit is placed. In a home position state of the patient shuttle system (100), the patient table and first and second arms of the patient table drive unit are configured to be folded in the height direction (Z-axis). A robot arm base connected to the second arm is fixed at a position off the center of the base in plan view, and thereby a helper space (135) where a helper may ride is secured on the base. The robot arm base is fixed in a recess (138) provided in the base.

Abstract: A function/process of recording marker position data and spot data is provided. The marker position data includes position information of a marker 29 measured for tumor tracking irradiation and information on time of execution of X-ray imaging. The spot data includes information on time of irradiation of each spot, a delivered irradiation position, and a delivered irradiation amount. The marker position data and the spot data are synchronized based on the time information, and by using the marker position data and the spot data upon spot irradiation, a delivered dose distribution of proton irradiation is calculated. With this configuration, it is possible to take the influence of interplay effect into consideration, and it is possible to support to make more appropriate determination upon replanning of a treatment plan.
