Title: CT and MRI scan - 3d reconstruction and analysis
Post by: kiaoi on 16/08/2010 07:32:39

Hi all,

I'm a Computational Fluid Dynamics researcher currently working on a book on respiratory airway modelling and I stumbled onto this community as I was after some information on CT/MRI's. I read that many people already have existing CTs and MRIs images and I wondered that instead of obtaining new CTs from hospitals what about those that already have CTs and if they were interested in sharing those scanned images with me. I'm not sure if this is internet etiquette and I don't mean to offend anyone but rather I thought this might be an opportunity to use the internet to enhance research capabilities. What it will involve is that I get a set of CT or MRI scans and reconstruct the respiratory airway and use some engineering software to analyse the fluid flow features. With any of the reconstructed models and analysis I would of course provide the person with the 3D-model and any analysis involved. Some of my work includes the following:

1. Wen J, Inthavong K, Tu JY, Wang S. Numerical simulations for detailed airflow dynamics in a human nasal cavity. Respiratory Physiology & Neurobiology2008;161:125-35.
2. Inthavong K, Wen J, Tian ZF, Tu JY. Numerical study of fibre deposition in a human nasal cavity. J Aerosol Sci2008;39(3):253-65.
3. Inthavong K, Tian ZF, Li HF, Tu JY, Yang W, Xue CL, et al. A numerical study of spray particle deposition in a human nasal cavity. Aerosol Sci Technol2006;40(11):1034-45.

Some targeted outcomes include:
How can this process from scan to final 3d model and analysis be sped up?
How to create new models to reflect real physiological functions?
To create a viable virtual surgery and 3d training and research tool. Virtual anatomy can contribute towards this learning by providing the three-dimensional models of the anatomy that can be manipulated visually to convey the concepts. Surgical procedures can be made virtually, and then its effect on fluid flow patterns through the anatomy can be analysed. The surgeon therefore can make a more informed decision on the surgical procedure as well as devising a more effective post surgery recovery plans. One final advantage of the virtual anatomy and surgery, is that communication between medical practitioners and the patient and their family will be improved through the visually demonstrating the antomy and why surgery is or is not needed.

Of course if you are interested there is complete confidentiality and ethical standards that we work under. You can PM me or email is you like.

Thanks for your time reading this! [;D]

Barkis is willing, but I haven't had any thoracic studies...just a couple of abdominal one's.

You may run into an obstacle in the US due to the HIPPA regulations. The patient's records are totally transparent to any insurance company, but US administrators are all terrified of a lawsuit and so medical information can be hard to access for anyone else.

Thanks but I need airway/thoracic scans. Especially anyone with disorders such as sleep apnea. I also realise there's lots of different laws for different countries. I have all the confidentiality and ethics forms from our research institution.

Hi,
I have a CT scan of the thoracic region you can have with pleasure. I also have an MRI of the thoracic and cervical spine on it's way. Just give me a shout.

This maybe worth a look ...

Dear fellows,

I am currently working on nasal cavity but I am looking for the real geometry that compatible with FLUENT software.

Thus if possible can you share that geometry with me so I can further my knowledge on this field...

You can send email or link that download that geometry to: Email address deleted by Mod to spare Leo from a load of spam. Please send him a PM if you can help.
Thank you very much.

Leopold,

I hope you don't mind, but I deleted your e-mail address from your post. TNS has a wide distribution on the Web, and so would your e-mail address! If it's out there, you will get an incredible amount of spam sent to your e-mail address.

Other TNS members will be able to send you a Personal Message (PM). If they do, you should also see an e-mail to let you know that they have.

Good luck with your research!

Geezer

noted... thanks Geezer!

So anyone interested in sharing those model, please pm me...

thank you very much and have a good day.
