AI Technical Summary
Technical Problem
Existing external radiation therapy systems cannot effectively address the positional changes caused by the non-fixation of internal organs and the skeleton, resulting in decreased treatment precision and damage to healthy tissues.
Method used
The robot arm, combined with a positioning tool, is used. The movement of the robot arm is controlled by a processing unit to precisely adjust the position of the target organ during radiotherapy. An expandable catheter inserter and a guide device inside the catheter are used to ensure that the organ remains stable during radiotherapy.
Benefits of technology
It improves the precision and safety of radiotherapy, reduces damage to healthy tissues, and decreases the expansion of the treatment area and side effects.

Abstract
This relates to a robotic arm combined with a positioning tool that repeatedly and reproducibly positions the body relative to an ionizing radiation therapy beam during treatment. [Solution] A radiotherapy treatment system is provided to assist in the treatment of a subject in an extracorporeal radiotherapy program comprising one or more extracorporeal radiotherapy treatment sessions, the system comprising a robotic arm 400 having a proximal end and an effector end, and a steering guide 300 having a proximal end and a distal end, the distal end having a rigid effector shaft configured to be inserted into a tube of the subject or to be attached to an inserter configured to be inserted into a tube of the subject, and a placement tool 200 configured to move and / or fix the tube for an extracorporeal radiotherapy treatment session in response to the movement of the robotic arm 400.
