EPISCAN - I - 200

The EPISCAN is a high frequency ultrasound scanner that utilises ultrasound in the range 20 to 50MHz to image skin and underlying soft tissue.

The system is portable such that it can be taken to the patients bedside as well as being used in “walk in” clinics

The system has been designed to be user friendly and includes measurement and images assessment tools.

approvals and clearances
Approvals and Clearances

Diagnostic ultrasound is a safe and well established imaging modality that remains the preferred imaging tool of clinicians around the world

Longport’s EPISCAN system has gained both European CE and US FDA clearance.

Units are also UL kite marked

slide8

FDA Clearance

“EPISCAN I-200 high-frequency ultrasound system is a specialized system for imaging the skin and underlying soft tissue. It is intended for use by clinicians, or under the direction of physicians for imaging and analysis in research environments as well as clinical settings including medical / surgical dermatology assessment and diagnosis (aesthetic and therapeutic), plastic / reconstructive surgical planning, wound assessment and management, skin assessment for pressure ulcer detection and prevention and superficial musculoskeletal diagnosis.”

wound prevention and assessment
Wound Prevention and Assessment

One of the main applications of the EPISCAN is the prevention and assessment of wounds.

Intervention based upon the high frequency ultrasound images has been shown to result in the prevention of open wounds and the accelerated healing of existing wounds

Recent comments on wound prevention from studies conducted with Longport’s technology and from customer

  • We conclude that EPISCAN, in extended care rehabilitation units, is a cost-benefit to providers for preventing costly pressure ulcers. The expected cost savings for the at-risk patient is approximately $5,300.00 per resident over a 1 year period. Ron Shannon, quote from poster presented at SAWC April 2007
  • Use of ultrasound for early care planning is a new concept but can have a significant impact on clinical management of risk. Karen Zulkowski, quote from poster presented at SAWC April 2007.

…..the scanner’s utility has already been realized through reduced treatment costs the incidence of pressure ulcers at Hawfields had dropped to 2 percent in February 2007, from 7 percent in September 2005, and the nurses’ treatment time has been better utilized in other direct-care patient issues such as teaching, documentation, and assessment-related procedures. Max Kernodle (Longport customer) quote from article in Provider journal, April 2007

Wound Assessment

High frequency ultrasound images can provide data on issues such as wound undermining and sinus tracks as well as detect changes to the wound bed.

Unlike visual assessment ultrasound can see deep into the wound providing the clinician with early data on the evolving wound

Ultrasound does not cause damage to the wound

Quantitative Images Assessment

In many situation the clinician is looking to determine change that has that occurred as the result of a treatment plan and although the EPISCAN ultrasound images provide a reliable pictorial representation it is often preferred to have numerical data to work with.

Longport has developed software such that quantitative data can be extracted from the images. The approach taken is to analysis the distribution of signal strength used to write each pixel of the image or defined area of the image.

Examples of the data generated are shown in the following slides
