Hi Kris, They will be attending RSNA in Chicago in November. Hopefully by 2012 , they will get FDA approval. You can contact company CEO at dean@imaging3.com AsicProf

Hi AsicProf: Yes, it looks very promising...I will be happy to invite them to present at CMOSET conference in Vancouver in 2012 to present (I am the chair, www.cmoset.com), Kris

Hi Kris, They are waiting for 510 pre-market FDA approval before they can market the product. What you think about market potential of this technology , if it works as advertised.

Hi AGK, You seems to be knowledgeable in area of medical imaging. I want to know your opinion on medical imaging company , who claims to generate real time 3d images. Recently I came across a small company imaging3.com, who claims to create real time 3d image. They claim to construct 3d volumetric image of hand / skull in in real time. Their technology is not using FBP reconstruction algorithm. They basically use fluoroscopy to measure the distance reading from the surface of the targeted volume , by rotating X source 360 degree around the object.. These distance measurement eventually used to create 3d base map (volume envelope). Now once 3d base map is created, S/W just paste 2d picture on the 3d base map. This process gives a very fast construction of 3d volume image. The gantry and cart computer are synchronized on 3d base map ....ie. when user rotates the image on the computer screen ....a message is sent to gantry computer to re-scan new coordinate ....On the opposite side ...if target moves inside the gantry ....gantry computer re-scans the new view and send a message and new image to cart computer for update ... Below is the link of their technology patent. http://www.google.com/patents?id=piISAAAAEBAJ&printsec=abstract&zoom=4&source=gbs_overview_r&cad=0#v=onepage&q&f=false I am wondering whether this technology is really feasible, given that big medial imaging companies like GE, Toshiba, Philips, and Siemens could not think of this technique. I will really appreciate if you can give me your comment on this technology. AsicProf

3D OCT system by Dr Kohji works at 1310 nm center wave length and 250 narrow spectral band.They achieved OCT imaging of 60 million axial scans per second and demonstrated a 16 kHz frame rate with 1,400 A-lines per frame, a 3 mm depth range, and 23 µm resolution. With 14 bit resolution 50Mega samples per second a nearly 1GB data rate the processing is done by FPGA's with DSP. Great work and results. With this no more painfull biopsys

Hi iniewski i am interested to write a chapter on this. I will refer to various articles on this topic and prepare for you. Will it be allright

To @Benchuchu, interesting comments. I am editing a book on medical imaging for Wiley and planning to add OCT to standard modalities (MRI, US, CT etc). Would you be interested in contributing a chapter? kris.iniewski@gmail.com

This work is surely no better than the examples given by solarpower44, because of the physical/optical feature of OCT imaging itself. For OCT imaging, which is limited by the scattering of tissue itself, the imaging penetration depth is up to 1~2mm for normal biological tissue and may be up to 10mm for ophthalmological structures like cornea. The imaging size mentioned by particle60, which called lateral scanning range in OCT, is just determined by the number of A-scans in one volume, which is not related to the imaging processing part. Overall, OCT is kind of novel and upcoming imaging modality, which high resolution but shallower imaging depth compared to US or CT or MRI. I think the most powerful field for OCT is the ophthalmology applications, since eye itself is the most transparent part within the body.
