Abstract:
1. A method of tracking movement of an eyeball in eyeball tumor treatment, the method being applied to an eyeball tumor treatment system, the method comprising: a calibration step of a control unit of a control device of the eyeball tumor treatment system storing an actual length for each pixel of an image, output through an output unit of the control device, in a storage unit of the control device, wherein the calibration step comprises: a template image generation step of the control unit storing a patient's eyeball image, transmitted from the detection device of the eyeball tumor treatment system, as a template image of the patient's eyeball in the storage unit; an eyeball location tracking step of, during treatment of the patient's eyeball using a proton beam output device of the eyeball tumor treatment system, the control unit determining whether movement of the treatment image has occurred by comparing treatment images of the patient's eyeball received from the detection device in real time with the template image; and a control step of the control unit stopping operation of the proton beam output device if, as a result of the determination, the movement of the treatment image is determined to deviate from a preset tolerance range, and keeping operation of the proton beam output device normal if, as a result the determination, the movement of the treatment image range is determined to be within the tolerance range.
