Device to reduce time of radiation treatments

Description:

Project ID:  D2019-19

 

Background

Success of radiation therapy for those treated on a medical linear accelerator (Linac) is dependent on accurate positioning of the patient. The current system has the on-bard imaging device (OBI), consisting of a kV source and detector, which are rigidly attached to the gantry of the Linac. The device requires the MC head of the Linac to rotate around the patient with the OBI. This mandatory movement of the Linac’s head and counterweight takes 70-90 seconds to complete, which can compromise the positioning of the patient and thus image and treatment quality.

                                                                  

Invention Description

Investigators at the University of Toledo have developed a device whose C-Arm is not rigidly attached to the accelerator; the OBI can rotate independently of the head of the Linac. It is located isocentrically concentric with the treatment C-Arm and is capable of higher rotational speeds, resulting in faster scan times and thus improvements in image quality for gated imaging. 

 

Applications

-       Image Guided Radiotherapy (IGRT) treatment

                                                                                                   

Advantages

-       Faster image acquisition; more patient scans in a day

-       Less time of the table for patients

-       More accuracy of radiation delivery

-       Less expensive to operate

 

IP Status:       Patent Pending
