Breast-Specific Gamma Imaging (BSGI), a molecular breast imaging procedure, is made possible by a unique camera - the Dilon 6800. This high-resolution, small field-of-view gamma camera can detect early stage cancers (as small as 3 millimeters), see lesions independent of tissue density, and provide multiple angle views for direct correlation to mammograms.
The Dilon 6800's patented design incorporates advanced imaging technologies in a highly compact detector. With over 3,000 individual 3mm square detector crystals and 48 position-sensitive photomultiplier tubes (PMT), the Dilon camera has the resolution to provide very early detection of small lesions, providing a vital diagnostic adjunct to mammography and ultrasound. Because the crystals and PMTs are packaged in an easily maneuverable detector measuring 6" x 8" x 4", the Dilon 6800 can be placed in direct contact with the breast and chest wall- thus minimizing dead space.
Compact Detector - allows imaging close to the chest wall, making detection of lesions as small as 3mm possible.
Small, portable size - eliminates the need for a dedicated exam room.
Movable detector head - allows imaging in all mammographic positions, plus selective study of hard to reach areas such as the axilla.
SmartShield™ (gamma isolation shield) - eliminates shine-through and decreases scatter radiation from nearby organs; forms and stabilizes the breast without compression.
Capable of multiple acquisition angles
- Duplicate standard mammographic views
- Study "hard to reach" spots
High resolution
- Image up to the chest wall
- Improves lesion contrast to detect early stage cancers as small as 3 mm
Portable and affordable
- Locate in breast center for same-day diagnosis
- Mobile system eliminates installation and facility modification
Several additional procedures may also benefit from Dilon's small size, high-resolution and small field-of-view detector. Future applications could include gamma-guided biopsy, spot bone flows, thyroid imaging, testicular injury imaging and pediatric imaging. Dilon's technology sets the framework for quickly and cost-effectively developing other nuclear diagnostic applications.
Shine Through - The direct emittance of unwanted gamma rays from other organs such as the brain and thyroid in a CC view and the contra-lateral breast in the lateral view.
Scatter Radiation - The diffusion of gamma rays as they bounce off atoms within the field-of-view, which can interfere with proper image formation in the desired study area.
