Here is the first version of my research report. I just put together all the findings from the past weeks. So if you were reading this blog, than there is probably nothing new in the report for you. It’s just the first part of my official Thesis-report. Also its not finished, there is still a few blank pages and content might change later on. I’ve created a static page for the report on the right side of this blog, you’ll always find the latest version there too.

week 4 & 5 summary

leave a comment »

Week 4 & 5 have been a bit slow for me to be honest. I am not sure why I did so few progress in these weeks… I think one part of it was that I moved to Sweden. You can clearly see that I haven’t done to much progress on my blog (lack of blog posts) – this blog gives me no chance to hide. Anyway…

I visited the Umea hospital in week 5 and it was really interesting to see the differences to the Netherlands (see last post). Sweden is a bit ahead in the healtcare networking thing.

Also I started in my Ideation phase in week 4 with a brainstorm at the Philips Design office.

week 3 summary – “Phase 02 – Ideation” directions

leave a comment »

I had the chance to speak to radiology-professionals for the first time last week. I analyzed their workflow and collected their thoughts and ideas. I tried to combine this with my research from the past 2 weeks. I pointed out problems in the work of radiologists and trends of radiology. This lead to 4 general topics I’d like base my ideation upon. I am going to use these directions for first brainstorm sessions at the Philips Design Department this week.

“Phase 02 – Ideation” directions:

1. Data Explosion
Technology is changing fast. New ways for scanning bodies are developed. Different technologies are combined (multi-modality) to get an even more detailed pictures of the body. A brain-scan can have up to 20000 pictures. Also patient history becomes easier accessible, scans from the past can be included in the analysis.
This is a lot of data to view for the radiologist, there is a need for specialized tools to be able to see what is important in all this data. data-visualizations should be an important part of these tools. radiologists are not dependent on viewing 2D slices anymore.

2. Comparing Cases (connected data in a Healthcare 2.0 world)
Nowadays radiologists use physical books, medical atlases to compare the body scans with examples of known diseases. But the trend goes to digital data, there are more possibilities for visualizing and comparing diseases than with a book. Patient history and information becomes easily accessible and can be incorporated into the diagnosis. Radiologists also like to collect their own special cases for future references. PACS is already the first step to centralize these collections and patient data, what is the next step?

3. Reporting for who?
Reports are normally generated automatically according to the protocol. But who views these reports? Different specialists need different information. New technology delivers more options of showing information (e.g. video and 3D). In the healthcare network of the future even patients could be able to access their own scans, but they don’t know how to read this information. A big advantage of the connected world is the ease of sharing knowledge, the system should be designed for this.

4.  Prognosis in the Radiology Department
Today a radiologist has about 3-5 minutes to view and analyze a case and make a diagnosis. Officially its not his/her job to make a prognosis (e.g. propose what treatment is needed). But fast developing technologies in the radiology field would make prognosis possible in the radiology department. And there is already a gray area: radiologists and surgeons work together to analyze images and decide on a treatment. Is this the radiology of the future – high specialized physicians working together to create a prognosis, maybe even in the radiology reading room? how should a reading room be designed to accomplish a seamless workflow for the individual specialists? what is the role of CAD and teleradiology in making prognosises?

Week 2 summary

leave a comment »

In last weeks summary I formulated 8 topics for my research. This week I mostly concentrated on visualization techniques. I reviewed my research plan and marked everything I covered this week in green. Next week I have meetings with Application Specialists and a hospital visit. I am also planning to start my official research on Natural Interfaces (but actually this is the field in which I have a lot of knowledge already, I just need to connect it to Radiology). I marked next weeks research areas in blue. I briefly touch all these areas, depending on my final direction I might need to continue my research on some of these topics later on.

Automated Image Comparison and CAD seems to be the most difficult research area for me. I tried to get some information, but it is hard to find. Papers I found are dealing mainly with math and algorithm for detecting patterns and comparing images. That’s not helping me at all…

– Natural Interfaces, Touchscreens and beyond
– Automated Image Comparison (and artificial Intelligence and CAD)
– Image viewing, editing and enhancement
Data Visualization (with medical 2D, 3D, 4D and 5D? data in mind)
Healthcare 2.0 (everything goes digital: teleradiology, PACS, EMR)
– Radiologists today (workflow, human interactions, technology usage, problems etc…)
– Medical Imaging (CT, MRI, Ultrasound, Fluoroscopy, Nuclear Medicine and how these work together)
– Market research of devices and concepts

Week 1 summary

leave a comment »

The first week of my project was full of new information and impressions. A new place to live, a new city to explore, a new office to work in and some nice people to get to know. I haven’t seen a lot of Eindhoven yet, but I’ve seen a lot of medical images and machines already. And that’s exactly what I am here for. I didn’t know anything about Radiologists before I came here. So I was reading a lot about them this week. Radiologists and medical imaging shaped up as something much more complex and much more interesting than I thought before.

My research was a bit unsystematic this week, mainly because I didn’t know anything before. Apart from visiting a hospital next week, I am aiming to focus on some key aspects for my research:

– Natural Interfaces, Touchscreens and beyond
– Automated Image Comparison (and artificial Intelligence and CAD)
– Image viewing, editing and enhancement
– Data Visualization (with medical 2D, 3D, 4D and 5D? data in mind)
– Healthcare 2.0 (everything goes digital: teleradiology, PACS, EMR)
– Radiologists today (workflow, human interactions, technology usage, problems etc…)
– Medical Imaging (CT, MRI, Ultrasound, Fluoroscopy, Nuclear Medicine and how these work together)
– Market research of devices and concepts

Also we visited the Philips Healthcare showroom in Best this week. I had the chance to play around with some pretty expensive scanners and with a working Radiologists Reading Room. I hope to get a set up of a reading room in our office soon. Here are some picture of the showroom:
