Title: Prone Breast Shield for Contralateral Breast During Prone Breast Cancer Irradiation

 

Invention: This technology consists of a novel method and device for decreasing scatter radiation to the heart and lungs during prone position breast cancer radiotherapy.

 

Background: Current radiotherapy treatments have the potentially harmful side effect of exposing a patient’s heart and lungs to radiation. Numerous studies have shown that this exposure can have serious effects on a patient’s long-term health. Patients treated with breast cancer radiotherapy have an increased risk of developing a second primary breast cancer as well as an increased risk of late cardiovascular and pulmonary complications from breast radiotherapy. Therefore, precise patient positioning and open access to the breast are becoming of greater importance for effective treatment.

 

Applications:

  • Radiation therapy 

 

Advantages:

  • Reduces the dose to both sides of a modeled contralateral breast
  • Reduces radiation exposure to surrounding organs and tissues, particularly the heart and lungs
  • Respiratory motion may be reduced by adding an inspiratory gating to patients in the prone position
  • Improves treatment accuracy
  • Lowers the risk of long-term health complications
