Longport High Resolution Ultrasound


System Description

Longport’s high resolution ultrasound system the EPISCAN-I-200 has been designed to image the skin and underlying few centimetres of soft tissue with great clarity. Ultrasound of centre frequency as high as 50MHz can be utilized to provide clear images of the skin’s structure, visualise the impact of many of the diseases and injuries that inflict this region and monitor the impact of treatments.

The EPISCAN’s software operates under Windows XP and has been designed to be user friendly as well as providing the user with a series of features and functions that allow image annotations and measurements to be performed as well as comprehensive patient record keeping. Further, digital photographs can be imported.

The EPISCAN has been designed to occupy a small space in a clinician’s office or treatment area and can positioned on a small trolley or a desk.


Dermatological Applications

Applications include:• Skin lesion mapping• Monitoring the impact of aesthetic procedures on the

skin• Assessing the impact of medications on the skin• Wound and scar assessment• General assessment of skin conditions and diseases

and the monitoring of treatments


30MHz Ultrasound Image of Inner Arm

Note increased skin thickness and reduced reflections from upper levels of dermis compared with previous inner arm scan. These changes are believed to be the result of sun induced damage.

Quantitative Assessment of Images

Many applications of the EPISCAN relate to assessing the impact of a treatment or process, where the user is looking to measure the differences to result from their intervention normally over time. The EPISCAN offers a series of tools to help quantitatively measure changes that may occur as well as providing the user with the ability to visually qualitatively asses sequences of images tiled on the screen.

Most simply quantitative measurements can be linear measurements or area measurements, for example measuring dermal thickness. The EPISCAN also provides the user with the means to compare the make-up of the reflected signals that is used to create the images.

The following example assess the signal strength of each pixel that makes up the image or from a defined area of the image.

Pixel Analysis

The previous images show the same area of skin before, during and one hour after saturation with a moisturiser. One each image an identical area was defined and the pixel intensity distribution determined within that defined area. The resultant distribution plots are shown on the page following this.

These plots show that prior to the application of the moisturizer the average intensity of the pixels was higher and that one hour after the removal of the surplus moisturizer there had been a small but measurable change back towards the pre application condition. (This trend is as expected as moisturizing or hydrating of the skin lessens the ultrasound reflections.) The final page of this sequence shows numerical representation of the distribution plots.

Changes in collagen resulting from various treatments are expected to be assessable using this approach, thus providing the clinician with a numerical representation of skin ageing or rejuvenation.
