What is the purpose of this trial?

This trial tests a new imaging technology called HyperSight, which could enhance how doctors plan and deliver radiation therapy for cancer. HyperSight aims to provide clearer images with fewer delays, helping target tumors more accurately while avoiding healthy tissue. Suitable candidates for this trial include those diagnosed with cancer who need radiation treatment for areas like the head, neck, or lungs. The University of Maryland Medical Center conducts the trial. Participants must be able to give consent and will receive radiation therapy as part of their treatment. As an unphased trial, this study offers a unique opportunity to contribute to innovative advancements in cancer treatment.

Do I need to stop my current medications for the HyperSight Imaging trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that HyperSight Imaging is safe for use in cancer treatment?

Research has shown that the HyperSight imaging solution provides clearer images than traditional CBCT (cone beam computed tomography) systems. This clarity helps doctors target cancer more accurately during radiation therapy.

Studies have found that HyperSight improves image contrast and reduces blurriness, making it easier to see soft tissues. These improvements can lead to fewer mistakes and more precise treatments. Although these studies focus on image quality, they suggest HyperSight is safe because it enhances visibility without introducing new risks to the imaging process.

Overall, HyperSight appears to be a safe and well-tolerated imaging method, enhancing the accuracy of radiation treatments without compromising patient safety. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about HyperSight Imaging because it represents a novel approach to cancer detection and monitoring. Unlike traditional imaging methods like MRI and CT scans, HyperSight Imaging uses a cutting-edge CBCT (Cone Beam Computed Tomography) system, which can provide highly detailed 3D images. This technology allows for better visualization of tumors with potentially lower radiation exposure. By offering clearer images and more precise data, HyperSight Imaging could lead to earlier detection and more accurate treatment planning, making it a promising tool in the fight against cancer.

What evidence suggests that HyperSight Imaging is effective for cancer?

Research has shown that HyperSight Imaging, which participants in this trial will receive, greatly improves the quality of cone beam CT (CBCT) scans. Studies indicate that HyperSight reduces image flaws and enhances clarity and detail compared to regular CBCT, resulting in clearer and more accurate images. HyperSight can also capture images in just 6 seconds, helping to prevent blurring from movement. These improvements make HyperSight a promising tool for better targeting in cancer radiation therapy. ^{6 7 8 9 10}

In a study of 42 ERCP procedures using cone beam computed tomography (CBCT), it was found that conventional ERCP had a significantly lower median radiation dose compared to CBCT methods, indicating that for simpler procedures, traditional 2-D x-ray techniques are safer in terms of radiation exposure.

However, CBCT can be beneficial for more complex cases, potentially reducing procedural time and the need for additional contrast injections, suggesting that it may improve efficiency in challenging situations despite higher radiation doses.

C-arm Cone Beam CT (CBCT) enhances the safety and accuracy of interventional procedures by providing detailed cross-sectional imaging for preprocedural planning, intraprocedural guidance, and postprocedural assessment.

Despite some technical limitations, such as lower image quality compared to conventional CT and challenges in quantifying radiation doses, CBCT is proving to be a valuable tool in the interventional suite, with the potential for further evolution and integration into clinical practice.

Three-dimensional cone-beam (CB) imaging provides superior visualization of important anatomical structures compared to digital orthopantomography (OPG) in patients undergoing implant surgery, based on a study of 27 patients.

While CB imaging offers a level of detail comparable to computerized tomography (CT) for high-contrast structures, it is important to consider the higher radiation exposure associated with CB imaging when making clinical decisions.

The average effective dose (ED) of radiation from abdominal C-arm cone beam computed tomography (CBCT) was found to be 4.3 mSv, which is significantly higher in the upper abdomen compared to the lower abdomen and increases with patient weight.

The radiation exposure from CBCT is comparable to approximately 7.2 minutes of fluoroscopy, and the lifetime risk of cancer death from this exposure is estimated to be 0.033% or less, indicating a relatively low risk associated with this imaging technique.

The study found that a single megavoltage (MV) cone beam computed tomography (CBCT) scan increases the skin dose in the treatment area, with doses ranging from 0.5 to 1.4 Gy on the treated breast, which could raise concerns about potential toxicity and secondary cancer risks.

The additional skin dose from the MV CBCT was relatively low (0.02 to 0.05 Gy), but it still increased the overall out-of-field skin dose by about 20%, highlighting the need for careful consideration of imaging doses in clinical protocols for breast radiotherapy.

Cone-beam computed tomography (CBCT) is a reliable diagnostic tool for assessing conditions like impacted canines and root fractures in children, providing better evaluation of condylar shape and volume compared to conventional imaging.

CBCT is particularly advantageous for pre-surgical diagnostics in cases like cleft lip and palate due to its lower radiation exposure, shorter investigation time, and cost-effectiveness, but it should only be used when traditional radiography fails to provide a clear diagnosis.
