Description

Real-time Tracking Apparatus on Patient Movement to give visual feedback to patient}

The present invention relates to a device for tracking patient movement in real time. Specifically, it relates to a real-time tracking device for a patient's movement that provides visual feedback to the patient.

For successful radiation treatment of a tumor in a cancer site, the location of radiation to be irradiated to the tumor must be accurate.

In particular, when radiation therapy is performed on a body part related to the patient's breathing, the treatment area moves up and down according to the patient's breathing, so there is a problem in that the radiation irradiation position is not accurate.

Korean Patent Laid-Open Publication No. 10-2020-0118719, which is a prior art, places a motion measurement marker on a gantry structure other than the patient, but this method has a problem in that the motion of the patient is not reflected.

In general, tracking a patient's movement can be divided into a respiratory monitoring patient group and an eye pupil monitoring patient group.

When used with other types of devices used for radiation therapy, there is no restriction on the combination according to the shape of existing devices.

There is almost no dose reduction factor by the motion display device in the radiation treatment area.

Intuitive movement observation is possible by the horizontal laser and movement display device, so the treatment manager can do breathing coaching while setting up the posture without necessarily looking at the screen in the treatment room.

The IR sticker of the motion display device can be interlocked with the existing RPM, enabling double breathing monitoring.

It can be used regardless of the type of radiation therapy device. (Tomo, Lynac, Cyber therapy device)

Compared to existing equipment, it takes less time to set up the equipment and shortens the treatment time.

The audio coaching microphone speaker is located on the helmet and close to the patient's ear, enabling real-time communication even in a noisy treatment room environment.

It is designed to be applied differently according to the required treatment as a separate modular type.
