Senographe

Pristina

GE imagination at work

The Senographe* Pristina is a full field digital mammography

system designed to offer an extensive breast care solution

with screening and diagnostic capabilities, focused on an

ergonomic design for the technologist and patient comfort.

Senographe Pristina features a 24 x 29 cm detector, designed

to offer full breast coverage in a single image. Smaller breasts

can also be imaged in any view with paddles that can slide to

both sides of the detector.

The Senographe Pristina does not require daily calibration.

Ergonomics for technologists

• Re-imagined user interface

• Park Positioning during patient positioning

• One touch access to preset rotation for positioning

• Variable speed motorized gantry movements

• Sliding compression paddles can move to the side of the

detector for compression

Ergonomics and design for patient

comfort

• Designed for Patient comfort

• Wheelchair access, MITA compliant

• Thinner Bucky than previous platform

• Rounded edges detector for patient comfort

Image quality

• Automatic Optimization of Parameters (AOP), selects all

exposure parameters based on breast radiological properties

• Three AOP modes + 1 Automatic mode for implants

• eContrast is an image processing feature that makes

automatic adjustments of brightness and contrast

• DQE at IEC 62220-2-3 equivalent spectrum, at 75µGy:

70% (+/-3) at 0.5lp/mm and 64% (+/-3) at 2lp/mm

Smooth digital workflow connectivity

• Automated Quality Control

• Integrated Repeat and Reject Analysis
