Tips and hints for using the dS Breast Adaptive 16ch coil

Application Tip
Bickford, Lori, MS Philips Healthcare • USA
Rijckaert, Yvonne Philips Healtcare • Netherlands
Turk, Jackie Philips Healthcare • USA

The dS Breast Adaptive coil is designed for high image quality and high patient comfort.

This fully digital coil includes the following features:

- Open access

- Adaptive coil elements, contoured to fit the breast anatomy

- Single coil for both diagnostic and biopsy studies

- Axilla wing element with access for posterior biopsy

- High visibility lighting

- Tiltable head rest

- Coil cart included for ease of coil handling and storage of coil accessories

- Maximum weight allowed is 250 kgs

Tip 1: Connecting the coil

The coil plugs directly into the table (does not use the dStream box). 

Per the safety guidelines, a cushion is used to cover the table in place of the dStream interface box.


Tip 2: Patient positoning

Before positioning the patient, the lateral plates should be moved into a far lateral position. They do not need to be disengaged from the rails or the carriage, keeping the workflow easy.

The medial diagnostic plate remains in center position.

There are (removable) handles for the patient to use as a positioning aid.

Patient positioning is just as important on the dS Breast Adaptive 16ch coil as on any breast coil.

The wide open coil elements allow for a superb profile of the breast anatomy and easy access. 

Sling pad

A sling pad has been created to foster patient comfort. It contours to the patient shape, and distributes the patient weight to alleviate pressure points as much as possible.  Its attachment to the coil handles provides padding along the entire coil. The patient’s breast will hang freely through the sling pad, with the most inferior aspect of the breast at the very edge of the sling cushion.

Reach in from above to smooth any belly tissue out above the sling pad cushion, not allowing it to fall through the opening. This separates non-breast tissue from the breast so there is no fold inferiorly, and will help lessen fat suppression challenges.

The sling pad is to be centered between the lines marked on the rails, and should be held in place when getting the patient into position. This will keep the breast perfectly centered in the coil in FH direction.

Moving the lateral coil element into position

Once the breast is hanging freely with no folds, move the lateral coil element frame in by pushing evenly at the base, near the rails. The axilla coil element can gently support the patient if needed. Lock the lateral coil element frame into position. From the outside, click the clear solid immobilization plate into the coil element frame to minimize vibration (gentle immobilization is applied by the plate).

Tip 3: Enhancing patient comfort

To further enhance patient comfort, the 15 degree angle wedges can be used toward the medial aspect of the patient (see photo below).

If the patient indicates pressure at the sternum or lower ribs anteriorly, ensure to keep the breast in place while the patient gently tilts her hip up to the side as to position the wedge into place.

Insert the angle wedges only AFTER the patient is fully positioned into the coil.

If a patient’s chin uncomfortably rests on the cushion of the head rest, patient comfort  can be increased by positioning rolled towels under the clavicles (to slightly raise them up).


If the patient is very large and touching the top of the bore, the cushion under the sling can be removed for scanning. The sling will still need to be in place to support the patient and distribute the weight to minimize pressure points, but there will be some space gained in the abdominal region.

Tip 4: Intervention

The dS Breast Adaptive 16ch coil always has a total of 8 elements per breast (16 elements in total), enabling the same imaging parameters for intervention as for diagnostic procedures.

The clear solid immobilization plates can be replaced by grid plates in both the medial and lateral coil element frames.


Extensive lighting is available to increase visibility during the interventional procedure.


Tip 5: Protocols and ExamCards

Dedicated protocols for the dS Breast Adaptive 16ch coil are available in the Philips protocol database.
