METHOD FOR INCREASING THE ACCURACY OF A RADIATION THERAPY APPARATUS |
摘要 |
<p>Disclosed is a method for increasing the accuracy of images obtained in radiation therapy apparatus, such as a computed tomography simulator which employs an image intensifier and a photodiode detector for converting light from the image intensifier to electrical signals for further processing. The method recognizes that a significant amount of crosstalk can exist in the image intensifier and photodiode detector chain and provides a series of steps for adjusting the electrical signals obtained from the photodiode detector to compensate for the crosstalk.</p> |
