Proper technique and protocol adherence are crucial for optimal image quality and dose efficiency. Technologists should be thoroughly trained in the specific procedures for this exam modality.
Image Quality and Optimization
Achieving optimal image quality requires understanding image parameters, tailoring settings to breast types, and recognizing/reducing artifacts for accurate diagnoses.
Understanding Image Parameters
Image parameters are crucial for diagnostic accuracy with the Selenia Dimensions system. Key settings include kVp, mAs, and filtration, directly impacting image contrast and patient dose. Understanding their interplay is essential. The system allows for automatic exposure control (AEC), but manual adjustments are often necessary for specific breast densities or patient sizes.
Pixel size and matrix also influence resolution; smaller pixels generally yield sharper images. Proper collimation minimizes scatter radiation and improves image clarity. Furthermore, understanding the impact of compression on image quality is vital – adequate compression reduces motion and minimizes dose.
Regular quality control testing ensures these parameters remain within acceptable ranges, maintaining consistent image quality and reliable diagnostic results. Careful monitoring and adjustment of these settings are paramount for optimal performance.
Optimizing Image Quality for Different Breast Types
Achieving optimal image quality requires tailoring protocols to varying breast compositions. For fatty breasts, lower kVp and mAs settings can suffice, minimizing dose while maintaining sufficient contrast. However, dense breasts necessitate higher settings to penetrate the tissue effectively.
The Selenia Dimensions system’s automated exposure control (AEC) assists, but manual adjustments are often needed. Consider utilizing contrast-enhanced mammography for dense breasts to improve lesion detection. Compression techniques should also be adjusted; firmer compression is generally beneficial for dense tissue.
Regularly evaluating image quality and adjusting parameters based on breast density classifications is crucial. Utilizing the Low Dose Genius 3D MAMMOGRAPHY exam can further enhance visualization in challenging cases, improving diagnostic confidence and patient care.
Artifact Recognition and Reduction
Image artifacts can compromise diagnostic accuracy on the Selenia Dimensions system. Common artifacts include motion blur, caused by patient movement during acquisition, and metallic artifacts from jewelry or implants. Proper patient instruction and removal of metallic objects are preventative measures.
Grid lines can appear as linear artifacts; optimizing grid alignment during maintenance minimizes this. Streak artifacts may arise from insufficient collimation or scatter. Utilizing appropriate collimation and scatter reduction techniques is essential.
The C-View software aids in artifact reduction during 2D image reconstruction. Technologists must be trained to recognize and mitigate artifacts, repeating exposures when necessary to ensure high-quality, interpretable images for accurate diagnosis.
