What
makes Episcan's technology different than other products?
There are numerous
features and advantages to the EPISCAN as compared to other ultrasound
systems. The main advantage is in the resolution of the images. The
EPISCAN utilizes ultrasound up to 50 MHz transducer that allows for
a resolution to 40 microns. This provides the user with microscopic
images of the areas of interest. Also, the EPISCAN utilizes a Windows
Operating System that makes it user friendly and portable enough to
go to the patient, rather than having to be transported offsite. The
images are digital making them convenient for printing, storage and
transporting. The system utilizes the power of the PC to provide a variety
of features including the importing of photographs, image measurements
and annotations and application specific features such as risk assessment
for pressure ulcers. The system includes network connectivity, DVD backup,
internal card readers and wireless technology. Overall, the EPISCAN
is designed to image the skin and superficial soft tissue at a microscopic
level, while providing the clinician with a user friendly, point of
care tool to provide valuable information and improve patient care and
outcomes.
Why
is network connectivity important?
In today's world,
it important to be able to transport information rapidly and accurately.
Data can be captured at the point of care and interpreted offsite. An
example of this would be at a nursing home where a nurse can image an
area of a suspected pressure ulcer and the image can be interpreted
offsite. This gives the patient the advantage of having the study performed
in their own bed, but having the expertise of a specialist read the
image and make appropriate recommendations. Also, network connectivity
allows for the archiving of data offsite.
What
can be seen utilizing the EPISCAN?
The EPISCAN images
the skin and superficial soft tissue at a microscopic level. The different
layers of the skin can be visualized in detail. The subcutaneous tissue
and deeper structures can be seen to a depth of 2 to 3 centimeters.
Subtle changes in fluid content, thickness or tissue density can be
appreciated. The skin is the largest organ of the body. Conditions such
as pressure ulcers, chronic wounds, burns and skin cancers are very
common problems. Also, the skin is a great indicator of various systemic
diseases. The EPISCAN can image these pathologies economically and accurately,
giving the clinician more information and allowing for improved patient
care.

Technology
Ultrasound has been
utilized by the medical community since the 1950's as a safe and flexible
imaging modality. Over the last fifty years technological developments
have substantially broaden the range of applications for ultrasound
imaging, improved image quality, data processing and image presentation
and
enabled
the miniaturization of systems into portable units. These developments
have resulted in ultrasound still being considered the imaging modality
of first choice by most clinicians despite the more recent introduction
of technologies such as MRI, CT, PET etc.
The evolution of
ultrasound imaging and the introduction of these other imaging technologies
have however not addressed the imaging requirements of the surface of
the body, despite the skin and underlying soft tissue being the subject
of many diseases and injuries. Here, a combination of very high resolution
imaging and the ability to differentiate between subtle differences
in soft tissue characteristics is required. Systems addressing this
need also have to be affordable to the clinical groupings associated
with dermatology, wound care, aesthetics, etc. and be user friendly.
Longport has developed
ultrasound imaging technology that addresses these requirements, the
EPISCAN I-200.
This
EPISCAN utilizes broadband ultrasound at frequencies from 10 to 50MHz
to image the skin and underlying soft tissue. The system is primarily
digital in design enabling flexible and cost effective data processing
and presentation. The ultrasound data is digitalized in real time at
rates up to 200MSPS (200 million samples per second) allowing the capture
of the maximum amount of information. A series of interchangeable probes
provide the user with a range of imaging options.
Longport's software
operates under a Windows environment providing the user with a comprehensive,
but user friendly interface.

Some of the features
of the EPISCAN's software are:
* Multiple images
can be tiled on the scanner screen allowing the progression of conditions
or different scan sites to be readily compared.
* Measurements, including linear and area measurements can be performed
and stored onto images.
* Image assessment techniques such as pixel intensity distribution can
be undertaken.
* A range of palettes, grey scale and color can be applied to the images.
* An integrated relational database enables images and other data, including
digital photographs, to be stored and retrieved in a patient orientated
manner.
* When scanning the images are retained in "memory loop" enabling
the user to review a series of images at the conclusion of the scanning
process and to select what image(s) should be stored.

The EPISCAN can
be connected to a network via cable or wireless means enabling data
captured to be backed-up or shared with other clinicians within the
facility or remotely. Thus the EPISCAN is compatible with telemedicine
use including DICOM configured systems. A read / write DVD ROM enables
data to be backed-up or transferred by this means as well.
The EPISCAN can
be readily taken to the patient's bedside via and an optional cart.
A medical grade UPS, (not illustrated) enables the system to remain
powered up when being transferred between patients beds, thus optimizing
system utilization.

Applications
/ Wound Assessment and Prevention
The EPISCAN can
be a valuable tool in the assessment of chronic ulcers. It allows
the user to look beneath the wounds for subtle changes that may affect
clinical decision making.
The EPISCAN can be used for the following:
* Visualization
of tissue beneath the wound
* Visualization of wound undermining
* Visualization of sinus tract formation
* Visualization of sub-wound edema
* Visualization of foreign bodies
* Documentation of effectiveness of wound treatments
Visualization
of tissue beneath the wound:
Up until now the caregiver could only visually assess the surface
of a wound. The EPISCAN allows the user to look at tissue beneath
the wound to see what is occurring. It can aid treatment decisions
by helping to determine how deep the wound penetrates and the quality
of the tissue beneath the wound.
Visualization
of wound undermining:
It is common for wounds to undermine under the skin expanding much
wider than the wound surface. The EPISCAN allows the user to image
the peri-wound area to see if undermining is occurring. This can change
the treatment regime and require more aggressive debridement or packing
of the wound.
Visualization
of sinus tract formation:
Sinus tract formation is common in wounds. In fact since we can see
with ultrasound that most wounds begin deep and then tunnel to the
surface, it would be expected that many such wounds have deep sinus
tracts. The EPISCAN can visualize sinus tracts which may necessitate
more aggressive debridement and exploration. This may also alert the
healthcare provider to the possibility of ostoemyelitis which may
warrant further diagnostic testing.
Visualization
of sub-wound edema:
Many wound care experts and researchers believe that edema under a
wound is a prime reason for slow healing. A variety of treatments
are aimed at reducing this edema. The EPISCAN is the perfect tool
to monitor the effectiveness of these treatments.
Visualization
of foreign bodies:
There are times where there are foreign bodies within the wound tissue.
This could be suture or various other structures. Examining the wound
with the EPISCAN could help identify these foreign bodies and also
help navigate the clinician to the exact location to aid in their
removal.
Documentation
of effectiveness of wound treatments:It is extremely important to
document wound appearance, treatment, and outcome as documentation
aides in appropriate continuity of care and positive clinical outcomes.
The EPISCAN is an excellent assessment tool for this documentation.

Applications
/ Wound Prevention
Pressure ulcers
are a common problem in any situation where patients are compromised
because of immobility, nutrition, incontinence, or age. They are very
painful and very costly. Preventive measures such as pressure relief
aids, specialized beds, and mattresses are expensive and therefore
cannot be used for every patient. Targeting the pressure relief is
a much more cost effective way to manage this problem. By having advanced
knowledge at the time of admission that a pressure ulcer is forming,
the caregiver can take the appropriate steps to prevent its development.
The EPISCAN is
ideal for use within acute and long term care facilities for the early
detection and prevention of pressure ulcers. Its portability allows
it to be used at the bedside. Its ease of use makes it possible to
do an exam in a minimal amount of time.

Pressure ulcers
are a prime outcome measure for long term care and acute care facilities.
"Pressure ulcer development is an important outcome measure because
it is a common complication, it is largely preventable, and it can
be costly both to patients and to health care providers." (US
Department of Health) Currently pressure ulcers are considered by
CMS to be both a high cost and high volume
condition. According to the CMS final ruling released on August 1,
2007 by the Office of External Affairs; beginning October 2008, CMS
will no longer reimburse for reasonably preventable hospital
acquired pressure ulcers.
Pressure ulcers
are a primary cause for litigation and regulatory sanctions. The reported
incidence of pressure ulcers varies greatly among studies; however,
all agree that the incidence should be lower than what presently exists.
Acute-care hospitals treat about 2.5 million pressure ulcers each
year according to the Institute for Healthcare Improvement.
Long term care
reports a national average of 13% for incidence of high risk residents
with pressure ulcers.
Estimates for
the cost of treating all pressure ulcers in the US range anywhere
from $1.3 - $11 billion annually. (Wall Street Journal)
