The present invention relates to an in vivo radiation amount measuring instrument. An in vivo radiation amount measuring instrument according to the present invention comprises: a main body elongated along an in vivo inserting direction and capable of supplying a fluid; an expanding part having at least a portion thereof fixed or connected to the main body and capable of being expanded and contracted by means of the outflow/inflow of the fluid; and a radiation measuring part disposed on the expanding part and measuring the amount of surface radiation distribution on in vivo tissue which the expanding part contacts by expanding.

In vivo radiation amount measuring instrument using film dosimeter that undergoes shape change with expansion

Disclosed herein is a method of tracking the movement of an eyeball in eyeball tumor treatment. The method includes a calibration step of storing an actual length for each pixel of an image in a storage unit, a template image generation step of storing a patient's eyeball image as a template image of the patient's eyeball in the storage unit, an eyeball location tracking step of, during the treatment of the patient's eyeball, determining whether movement of the treatment image has occurred by comparing treatment images of the patient's eyeball in real time with the template image, and a control step of stopping the operation of the proton beam output device if the movement of the treatment image deviates from a preset tolerance range, and keeping operation of the proton beam output device normal if the movement of the treatment image is within the tolerance range.
