Redefining the Medical Artist Exhibit

Posted by Janet on August 15, 2009

BioVisExhibit

I’m proud to announce an exhibit currently taking place at the International Museum of Surgical Science in Chicago. This exhibit, titled “Redefining the Medical Artist,” features the works of students, alumni, and faculty of University of Illinois at Chicago’s Biomedical Visualization program, where I am currently enrolled.

Although the Biomedical Visualization program at UIC, or BVIS, is the second oldest medical illustration program in the U. S., the program continues to push into the future. Traditional medical illustration is still in our background, but students who go through this program are encouraged to embrace technology and changes. Modern medical illustration is much more than an artist drawing on paper, thus the term “visualization” instead of “illustration” is used to truly capture the meaning of what we do.

Currently too many people, including many medical professionals, are still unaware of the field of medical visualization. “Why do we need illustrations when we can take photographs” is still the number one question I am asked when explaining to someone what I do. In reality we do use photographs and imaging technologies as part of our working process to visualize things that cannot easily be expressed.

“Redefining the Medical Artist” hopes to address these issues by bringing awareness of this specialized field to the public and showing that technology does not replace the need for medical art. Rather, it allows medical art to thrive.

*Special Thanks to Meena M. for putting together this exhibit and for everyone who contributed.

Modeling Lung Anatomy

Posted by Janet on August 8, 2009

Following “Visualizing Lung Anatomy,” I can now begin to model the lung. First, I took screen shots of the lung in VolView in three orthographic views–top, left, and front. Then I set up three orthographic planes and added each image as materials to the planes. I prefer this method over using a background image because this allows you to see the images in perspective views as you rotate objects. You also don’t have to worry about shifting your objects and locking zoom, which in my version of 3ds Max gets a little quirky.

Next, I put more planes in the scene, took a screen shot of every twentieth slice from the data set, and applied the screen shots to the planes as materials. Now that I have slices of the lung from front to back, I outlined each slice in the front viewport. Notice that the outlines are all located on the same plane. This will be fixed later. (If you are wondering why the “right” lung is on the left side, it’s because the “person” is facing us so their right is our left.)

Once the outlines are complete, I calculated the distance I must offset each line in order for it to fit the profiles correctly. After the outlines are moved to their correct positions, you can clearly see the shape of a lung in the perspective view. The lines must be linked together in order for a surface to be created. I selected one outline and used the “Attach Multiple” option under the modify panel. For now, I keep the front and back halves separate so I can easily hide the back side when necessary. Then, using the “Connect” and “Refine” features under the modify panel, I connected vertices between the outlines.

Here is what the model looks like with connections between the outlines:

LungModel6

Using the “Surface” modifier, I created a surface using this mesh. At this point it’s not perfect. I must go back and adjust the mesh until the entire surface can be covered:

LungModel8

The lung is looking nearly perfect, but overall still appears rough. Adding “Relax” and “TurboSmooth” modifiers will help refine the mesh:

LungModel9

This is one way to make a model of the human lung. I chose this method because I wanted to capture the accuracy in shape and had tools to visualize CT scan data. I also chose not to model the lobes separately because they are not the primary concern for this project and can be added later using materials.

Searching for Internships–Tips and Advices

Posted by Janet on August 4, 2009

Have really enjoyed reading about your internship, i graduated last year with an anatomical science degree and want to do somthing creative with it but have not found any jobs that combine the two…. this internship seems perfect tho! how did you find it?

Dear Louise,

These two links below list the current available internships at the Smithsonian’s National Museum of Natural History. Names and contact informations of the project sponsors are listed below project descriptions. Once you find an interesting project, you should contact the sponsor and have your resume (and portfolio if relevant) ready in case they ask for it. If your sponsor decides that you are a good fit for the project, he/she will contact you with further info.

http://www.nmnh.si.edu/rtp/other_opps/internship_projects.html

As far as how I came across this opportunity, I contacted people I knew in the illustration field for advice and then looked online until I found those pages. A few questions to ask yourself:

-What skills do I have?
-Do other fields value these skills?

In my experience, thinking about your specific skills rather than what you want to be forces you to think outside the box and will open up more opportunities. For example, I am trained in medical illustration, but I have both traditional and digital drawing skills, I’m good with details, and can draw faces. Instead of looking strictly for medical illustration jobs, maybe I can draw portraits on weekends for extra income, etc. etc.

-What types of companies do I want to work for?
-Where would I like to live?

These two questions generally help me refine the search results. General searches often times will not point you to a specific position, especially if the title of the position does not match your search keywords. If there is a list of companies you are interested in, you can go directly to the company’s website and see if they have anything available at the moment. Adding a location after a general search will sometimes tell you whether there is a market for what you would like to do in that area.

Hope that helps,
Janet
