Deep learning radiomics in cancer imaging - AACR 2021
This presentation was part of the AACR Virtual Special Conference: Artificial Intelligence, Diagnosis, and Imaging - January 13-14 2021
Plenary session 2: learning from images: radiomics
www.aacr.org/meeting/artificial-intelligence-2021/program-2/
Abstract:
Radiographic medical images contain a vast wealth of information allowing for accurate non-invasive tumor characterization and ultimately improving cancer care. Radiomics enables the extraction of mineable high-dimensional features from images, quantification of tumor phenotypes for survival, recurrence, and treatment response prediction, and ultimately better patient stratification. Recent advances in AI, deep learning in particular, has allowed for the automated extraction of imaging features without the need for pre-definition. In this talk, we will be exploring deep learning radiomics applications in cancer patients from both single time point and longitudinal imaging data. We will also be identifying challenges regarding the stability, reproducibility, and transparency of such approaches.

Bioinspired design of flexible armor based on chiton scales
มุมมอง 4175 ปีที่แล้ว
Man-made armors often rely on rigid structures for mechanical protection, which typically results in a trade-off with flexibility and maneuverability. Chitons, a group of marine mollusks, evolved scaled armors that address similar challenges. Many chiton species possess hundreds of small, mineralized scales arrayed on the soft girdle that surrounds their overlapping shell plates. Ensuring both ...
Oculus Rift DK2 Camera Mount
มุมมอง 2556 ปีที่แล้ว
Camera mount designed for the Oculus Rift DK2. A custom fitted mount for the DK2 was designed and created to hold two wide-angle fisheye lens cameras. The cameras add the ability to provide a stereoscopic real-world view to the user. The field of view for each camera was set to 90° for this mixed reality application. The double-camera mount prototype was 3D printed allowing for adjusting the in...
Deep Learning Intuition
มุมมอง 4346 ปีที่แล้ว
Abstract: In this session, we will be transitioning from traditional machine learning approaches towards deep learning. We will start by introducing some intuition behind deep learning and its perceived ability to approximate very complex non-linear relationships in data. We will cover the building blocks of neural networks, discuss how “learning” works, introduce key concepts for hyper-paramet...
Convolutional Neural Networks
มุมมอง 2326 ปีที่แล้ว
Abstract: Convolutional neural networks are the most prevalent deep learning architecture class used in medical imaging today. This session will build on the previously acquired knowledge of neural networks as we transition to working with image data and integrate convolutional layers. We will be covering convolution-specific concepts including receptive fields, weight sharing, strides, padding...

Aortic valve cusp generation in the browser
มุมมอง 8557 ปีที่แล้ว
Background: Successful transcatheter aortic valve replacement (TAVR) requires an understanding of how a prosthetic valve will interact with a patient’s anatomy in advance of actual deployment. To improve this understanding, we developed a benchtop workflow that allows for testing of physical interactions between prosthetic valves and patient-specific aortic root anatomy, including calcified lea...
Radiomics.io - A platform for everything radiomics.
มุมมอง 8K7 ปีที่แล้ว
Radiomics aims to quantify the radiographic phenotype through the use of automated AI algorithms. Radiomic technologies are based on either predefined engineered features or automated deep-learned features. Radiomic data can be used to develop non-invasive biomarkers in personalized medicine. With recent widespread adoption, there is a great need for standard open-source radiomic platforms, all...

Gaining quantitative insights from cell microscopy images can be a tedious task. A deep understanding of image analysis and bioinformatics concepts is required. When analyzing images, biologists are distracted by software errors and screens full of cryptic analysis configuration parameters. Data is processed on slow computers and sharing results with others can be difficult. Generating meaningf...
Three-dimensional printing of echocardiography data sets

This video is a step by step guide for creating .stl files from echocardiography datasets suitable for 3d printing. We demonstrate how to extract datasets from the echo machine, how to convert datasets to .nrrd files and finally how to use 3d-slicer to generate .stl files. We demonstrate a new technique to generate 3-D prints from 3-D echo data sets. The technique has widespread applicability g...

Keep up the good work 🤩😍
The same for me ... I´ll been serching how for two weeks😄
Much appreciated. I used to use version 4 and couldn't for the life of me figure out how to export in 5.2.. This workflow is so much easier!!!
I am working on radiomics model for predicting cancer and I have some questions if you have time to discuss please let me know
Can you please share the txt files
why?
Hey Ahmed, thank you so much for this great video. I am working on exporting 4D volumes from 3D TEE to be viewed on virtual reality headsets. I am facing a lot of barriers but I was able to use your method to reconstruct one frame at a time. 4 years after making this video, do you have any new tricks or helpful tips to share?
Very interesting!
Plese teach us how did you integrate them both?
and what shuld the camera do????
I can't believe that you answered in 28 seconds what these guys failed to answer in 3 years: discourse.slicer.org/t/save-volume-rendering-as-stl-file/524
When can we buy one?
In which software you use to alling STL data with mirror
Thanks for sharing!!
Awesome ! is there any English translation ?
Hay! Unfortunately no, but you get the gist of it :)
Hi Can I have the GH file?
Awesome video!!!
Awesome!!
Thanks so much.
Ahmed, could you please make a short video where you explain very very slowly and step by step how to connect grasshopper and matlab? I think this may be obvious for you, but would be very useful for most of us. Thanks in advance.
great work . :)
Dear Ahmed, After running both millipede and the top3dapp in matlab I was also interested in a direct link with matlab and GH, because I presume it runs quicker than millipede. Could you share the GH script? Thanks a lot!
