Esaote G Scan MRI

G-SCAN Dedicated MRI Unit
The G-scan magnetic resonance system is a dedicated musculoskeletal scanner,
specifically designed for limbs, joints and spine examinations.
The unique design of the magnet ensures high quality exams and
patient comfort during weight bearing or recumbent MRI exams.

Due to the compact system design, the system sites in as little as 245 square feet.
Thanks to its low energy consumption, the system can be connected to
a standard power outlet (220V).

G-Scan RF System
The S-scan RF system features a highly uniform and powerful RF system capable of
meeting the demands of a busy MRI practice. It has two 1800-watt RF amplifiers and
passive receive only coils, which expedite patient positioning and
imaging parameter flexibility.

G-Scan RF Coils
Set of 9 high-sensitivity, self-centering receive coils with automatic recognition;
most coils are equipped with the Dual Phased Array (DPA) technology,
using the advanced multi-receiver phased array techniques for optimal performance.
Coils also feature built in preamplifiers and low noise electronics ensuring
excellent image quality.
All coils come with a set of dedicated padding cushions, for patient comfort and
to reduce patient motion.

DPA Shoulder coil
Advanced shoulder imaging with ergonomic design for comfort.
DPA delivers highest SNR and image quality. (16.8 x 15.4 x 7.9 cm).
Shoulder coil
Solenoidal coil for maximum positioning flexibility, designed especially for
large shoulders and knees (14.5 x 17.5 x 12.6 cm).
DPA Knee coil
DPA coil for comprehensive views of the knee designed for
patient comfort and acceptance and large coverage area. (14.3 x 16.0 x 18.3 cm)
DPA Hand-Wrist coil
DPA coil designed for comfortable, high resolution imaging of the wrist and
hand. (11.9 x 7.2 x 20.0 cm)
DPA Foot and Ankle coil
DPA coil designed for optimized and natural positioning of the foot and
ankle and elbow (14.5 x 10.0 x 28.5 cm).
Flexible multi purpose coil
The flexible coil is a general-purpose coil. It is used when positioning with
the standard coils is difficult due to patient limitations. (Painful joint, inability to
assume a certain position). Includes Velcro positioning strap. (4 x 34 x 28 cm).

G-scan Standard Spine package
The G-scan spine package consists of spine coils for optimized imaging of
the cervical and lumbar spine.
X-Large DPA Lumbar Spine coil
The lumbar spine coil package features advanced coil design combining a flat coil built in
to the coil base and a removable belt coil which encompasses the patient.
There are 1 belt, X-large and to guarantee optimum imaging of the lumbar spine
regardless of patient habitus.

Cervical Spine coil
The c-spine coil is designed for easy patient positioning while delivering excellent images
of the cervical spine. It has a unique integrated flexion-extension mechanism for
imaging different neck positions.

Included in the package are a set of cushions and bolsters for stable and
comfortable positioning of the patient during the exam.

G-scan Advanced Spine Package
The G-scan Advanced Spine Package consists of 3 spine coils providing higher
signal uniformity and increased signal-to-noise.
4 channel Lumbar Spine Coils-Qty 2

The coils feature a 20% increase in SNR and two different sizes (medium and large)
to accommodate a larger patient population. The coils can be used for hip imaging
providing a 40% increase in SNR over the previous flex coil option. Included are a
set of cushions and bolsters for stable and comfortable positioning of
the patient during the exam.

Dual Phased Array Cervical Spine Coil
The new DPA C-spine coil provides better coverage signal uniformity and a 20% increase
in SNR. The coil sits into the patient bed and includes positioning cushions for
patient comfort.
