MRI-compatible intracavitary applicator inserted using ultrasound guidance to verify tandem placement in the uterus. Tandem and ovoids, tandem and cylinders, or tandem and ring chosen to accommodate patient's tumor and vaginal anatomy.

Computed tomography (CT) scan and a magnetic resonance imaging (MRI) scan performed after the implant is placed in the operating room. The CT scan should take about 20 minutes and the MRI about 45 minutes.

To determine the number of participants with improved image quality using the Novel Brachytherapy Applicator, using subjective and objective measures. In the subjective, for assessment of image quality for clinical use, the images obtained in the "shifted" position and in the "standard" position, were compared by a radiation oncologist without knowledge of which was the first and which was the second image. To provide and objective measure of the reduction in image artifact with the shields shifted, the bladder, rectum, and sigmoid were contoured, and average and standard deviation of Hounsfield units (HU) within these critical structures on the images were compared.

The number of participants with high quality images of the bladder, rectum and sigmoid with the adaptive applicator in the shifted position and standard position assessed by the Hounsfield unit values. The higher quality images are the images with higher density when the applicator is in either the shifted or standard position. The Hounsfield unit (HU) is a relative quantitative measurement of radio density used by radiologists in the interpretation of computed tomography (CT) images. The images obtained in the "shifted" position and in the "standard" position with the use of the adaptive applicator, were compared by a radiation oncologist without knowledge of which was the first and which was the second image.

Analysis was conducted using JMP Pro statistical software for patients diagnosis of 1B2cervical cancer

Single Arm in which eligible patients were women with a diagnosis of 1B2cervical cancer with definitive chemoradiation or radiation therapy who required brachytherapy.
