Standardizing Preclinical Dosimetry: The Dosequate™ Solution

Preclinical research relies heavily on small animal models to study disease and develop new treatments. When these studies involve radiation, accurate and reproducible dosimetry is essential for generating reliable and comparable data. However, the diversity of preclinical irradiators and experimental setups often leads to significant variations in dosimetry practices, hindering the ability to compare results across different labs and studies. This lack of standardization poses a challenge to scientific progress and can even impact animal welfare.

The Standardization Challenge in Preclinical Research

Unlike clinical radiotherapy, where treatment machines and dosimetry protocols are highly standardized, preclinical research often involves a wide range of irradiator models, beam energies, and experimental setups. This variability can introduce significant uncertainties in dose delivery and measurement, making it difficult to:

• Compare results across studies: Variations in dosimetry can lead to discrepancies in reported doses, making it challenging to compare results from different labs or even different experiments within the same lab. This can hinder the ability to draw meaningful conclusions and translate preclinical findings to clinical applications.

• Reproduce experiments: Reproducibility is a cornerstone of scientific research. Without standardized dosimetry, it becomes difficult to reproduce experimental results, potentially leading to wasted resources and delays in research progress.

• Collaborate effectively: Standardized dosimetry is crucial for effective collaboration and data sharing among researchers. When different labs use different dosimetry methods, it becomes challenging to combine and analyze data from multiple sources.

Dosequate™: A Standardized Approach

The Dosequate™ system offers a solution to the standardization challenge in preclinical dosimetry. By providing a consistent and reliable method for measuring absorbed dose, regardless of the irradiator or experimental setup, Dosequate™ enables researchers to:

• Ensure accurate and comparable dose delivery: Dosequate™ utilizes 3D-printed mouse phantoms with embedded alanine dosimeters to accurately measure the dose delivered to the target organ or tissue. This standardized approach minimizes variations due to differences in irradiator geometry or animal positioning.

• Improve inter-lab comparability: By using a consistent dosimetry system, researchers can be confident that their results are comparable to those from other labs using Dosequate™, facilitating collaboration and data sharing.

• Enhance reproducibility: Standardized dosimetry with Dosequate™ improves the reproducibility of experiments, leading to more reliable and robust data.

Benefits of Standardization

The benefits of standardized dosimetry with Dosequate™ extend beyond just improved data quality:

• Increased confidence in research findings: Standardized dosimetry enhances the reliability and credibility of preclinical research, increasing confidence in the results and their potential for translation to clinical applications.

• Improved animal welfare: By ensuring accurate dose delivery, Dosequate™ minimizes the risk of unintended harm to animals and reduces the need for repeat experiments, ultimately contributing to more ethical and humane research practices.

• Streamlined research processes with reduced costs: A standardized dosimetry system can simplify experimental protocols and reduce the time and resources required for dose calibration and verification.

The Dosequate™ system provides a much-needed solution for standardizing preclinical dosimetry, paving the way for more accurate, reproducible, and collaborative research.
