Transducer Covers - Philips EPIQ 7 User Manual

Transducer Covers

Transducers
Resolution, attenuation, and propagation artifacts are all common to 3D imaging. Careful
scrutiny of the original 2D images is necessary to identify and preclude these types of artifacts
from the 3D volume image.
Transducer Covers
To prevent contamination by blood-borne pathogens, sterile transducer covers are required for
intraoperative and biopsy procedures; in China, sterile covers are also required for transrectal,
intravaginal, and transesophageal procedures. Protective covers are recommended for
transrectal, intravaginal, and transesophageal procedures; the protective covers are mandatory
in China and Japan. Philips recommends the use of qualified covers.
For procedures for using transducer covers, see the instructions provided with the covers.
WARNING
Latex and talc are commonly used in sheaths marketed to help with infection control in
transesophageal, endocavity, and intraoperative imaging applications and during biopsies.
Examine the packaging to confirm latex and talc content. Studies have shown that patients
can experience allergic reactions with natural rubber latex. See the FDA Medical Alert, March
29, 1991, reprinted in "FDA Medical Alert on Latex" on page 49.
WARNING
In intraoperative applications, sterilized transducers should be used with sterile gel and a
sterile transducer cover.
WARNING
Do not apply the transducer cover until you are ready to perform the procedure.
WARNING
Inspect transducer covers before and after use.
