DigitalDiagnost benefitsfor long length imaging

• Available with all vertical stands and tables

• “Single focus” approach to minimize distortions

• Easy to perform- Adjust collimation, the system determines how many

images are necessary to acquire

• Low dose

• Fully automatic process- Images acquisition with motorized tube and detector

movements- Creation of the resulting composite image

o Manual correction possible

• No extra workstation- Everything done by the Eleva workspot- Includes dedicated orthopedic measurements

Automatic image stitchingPhilips’ single focus approach

Parallax error

Single focus

• More accurate overlaps areas• Minimizes stitching distortions

Multiple focus

• Big distortions in overlap areas

Single focus

Tube will rotate around its focal spot

Automatic image stitchingShow me how: acquisition principle

Movable vertical stand

Detector will move vertically from top to

bottom and stop to acquire 2 or 3 images

7

Automatic image stitchingShow me how: a 3 steps procedure

Movable vertical stand

Position patient standing in front of the detector(patient stand recommended)

26

Automatic image stitchingThe Eleva concept advantage

• Thanks to Eleva, long length imaging is seamlessly integrated in you workflow

– Fully automatic motorized acquisition procedure– Fully automatic stitching algorithm

• Manual override possible

– UNIQUE image processing– No extra workstation

• Saves space and time

– Dedicated orthopedic measurements• Cobb’s angles, femoral height difference, segments,

angles, measurements calibration

• Fast & efficient procedure– Customized exposure & image processing presets– Performed with very few clicks (touches)

Automatic image stitchingLatest literature on low radiation dose & pediatrics with DigitalDiagnost

A big improvement in Digital Radiography

Philips DigitalDiagnost minimizes X-ray doses at Val d’Hebron Maternity/ Children’s Hospital, Barcelona, Spain.

(Customer testimonial, October 2010)

Low-Dose Full-Spine Radiography with Digital Flat Panel Detector and Image Stitching System

When imaging scoliosis patients, a flat-panel detector combined with an image stitching system can substantially reduce the exposure dose.

(Study made on DigitalDiagnost, Germany, November 2011)

Extra ruler for table

• Patient stand- More comfort and confidence

throughout the procedure

• Spine stitching filters- Minimize ghosting artifacts

with challenging patients

• Extra lead ruler, straps

• Comes with dedicated guide

Automatic image stitchingFlex room swiveling table and stitching

• In small rooms, a swiveling table can be a great complement to stitching

• Table is swiveled during stitching procedure

• Gives more space and avoids the tabletop being in X-ray beam

• Improves

Access to the patientAccess to the system Image quality

32

Automatic image stitching with PCREven more long length imaging flexibility with PCR integration

• With PCR integration & stitching together, automatic stitching is also possible on DigitalDiagnost with PCR “long view” cassettes

- 2 or 3 imaging plates per cassette- Plates images are automatically stitched together after cassette reading- Several cassette sizes available to fit dedicated needs

• Same stitching algorithm & UNIQUE image processing- Comparable image impression with DR

• Quicker acquisition procedure than DR stitching- Only 1 exposure shot

• Alternative to DR stitching for some particular situations- Agitated patients- Patients who cannot stand for more than a few seconds- Trauma

Example: a 24 x 57 cm or 10 x 23” cassette allows to X-ray a broken

femur with both knee & hip joins or a child spine
