Brief summary

This trial studies the quality of holographic mm-wave imaging in patients undergoing radiation therapy. Holographic mm-wave imaging is a common type of imaging used in airport body scanners that may be helpful in improving the efficiency and positioning of radiation oncology patients and their overall experience.

Detailed description

PRIMARY OBJECTIVES: I. To obtain patient images in a clinical setting and assess their quality. SECONDARY OBJECTIVES: I. To assess the registration agreement through a voxel-voxel distance-to-agreement metric. OUTLINE: Patients undergo holographic mm-wave imaging in radiotherapy treatment position after initial computed tomography (CT) simulation.

Design outcomes

Primary

Measure	Time frame	Description
Qualitative assessment of holographic image quality	Up to 1 year	Qualitative assessment of image quality by study physicians according to the scoring of each image as: 1 = High Quality (A); 2= Acceptable Quality (B); 3 = Poor/Unacceptable Quality (C). Lower value (1) represents a better score than higher value (3). There are no subscales and or total scores. The quality scores of the images will be tabulated.

Secondary

Measure	Time frame	Description
Image registration agreement between mm-wave holographic images and a cone-beam computed tomography (CBCT)/optical surface image	Up to 1 year	The distribution of the percent of points in voxel-voxel analysis to agree to better than 2 mm will be tabulated
