In 2016 we hosted two meetings - one in Washington and one in Vienna - please see below for the topics that were presented.

AAD Washington D.C, 6th March 2016

We were delighted to have a completely packed room at the first US OCT in Focus meeting. Thank you to those that were able to come. For those that couldn't make the meeting, please find summaries of each of the presentations below: 

Dan Siegel - Medical Imaging: The Economics                                                                                                                                                                          Dan presented an excellent overview of the reimbursement system in the US, taking examples from the reflectance confocal device (RCM) codes.

Orit Markowitz - Dynamic OCT
Orit presented outstanding results on the application of Dynamic OCT. Dynamic OCT gives the user the ability to visualise vasculature. Vascular patterns were observed for both melanoma and non melanoma skin cancers both of which displayed significant differences. Click here to view the publication 

Heidi Waldorf - The use of OCT in quantifying rhytides of the décolletage
Heidi  presented on a pilot study performed with rhytides decollatage and selphyl injections. The pilot study looked into the impact of micro needling vs fraxel vs non-treated area of striae. Using the OCT scans it was found that the area of striea vs normal skin had consistent finding of epidermal atrophy and anatomic changes consistent with previously published findings.

Nathalie de Carvalho - Dynamic OCT of vascular patterns in malignant melanoma
Nathalie De Carvalho performed a presentation on using Dynamic OCT to visualise the vascular changes present in malignant melanoma in accordance to tumor thickening. A recent publication titled “In vivo micro-angiography by means of speckle-variance optical coherence tomography (SV-OCT) is able to detect microscopic vascular changes in naevus to melanoma transition” had already shown the differences in the vascular patterns between the area comprised by the naevus and that corresponding to the melanoma.

Julia Welzel - OCT for margin definition before Mohs micrographic surgery
Julia Welzel demonstrated a method for margin definition of basal cell carcinomas (BCC) using OCT and a hyper-reflective pencil. By scanning the whole margin, OCT enables to detect tumor parts outside the margin defined by dermoscopy. This procedure may be useful to determine more exactly the borders of a BCC prior to Mohs micrographic surgery to reduce the number of stages and the risk for recurrence.

Mohammadreza Nasiriavanaki - OCT Skin Imaging and Image Processing
Mohammad R.N. Avanaki from Biomedical Engineering Department of Wayne State University, had an impressive presentation on OCT skin image processing. He briefly discussed the source of artifacts in OCT skin imaging and the places where image processing could effectively improve OCT images. He introduced algorithms for speckle reduction, intensity decay compensation, aberration & blurring reduction, refractive index adjustment and OCT 3D image compression. His results showed that the algorithms improve the quality of the OCT images whilst keeping the diagnostically relevant features. He also showed the results of a method for guided biopsy using VivoSight OCT machine. He demonstrated a method for skin modeling through statistical, geometrical, optical and morphological features extraction from OCT images. He also introduced a method for detection of dermal epidermal junction. He ended his talk by giving a concise introduction on photoacoustic microscopy technique that he is developing and planning to add to the OCT system to add the functional information to the OCT structural images.

Mette Mogensen - Gold nanoshells work as OCT contrast agent in hair follicles
Mette presented a study on using gold nano shells as contrast agents in hair follicles, sweat glands and fractional laser channels. A bright contrast was identified at the upper side of the hair shaft and was followed through the epidermis into the hairfollicles. Using gold nano shells on the palms of the hand the eccrine ducts were identified at the dermal level of the skin. The nano shells did not provide excellent contrast in AFXL channels, but the opening of the channel was more clear cut.

Triaging BCC with Optical Coherence Tomography: Can we avoid biopsying?

Dan SiegelDan presented an excellent overview of the reimbursement system in the US, taking examples from the reflectance confocal device (RCM) codes.

Back to previous meetings
