When Astronomy Meets Medicine: The Fascinating Intersections of Space and Health

The Intersection of Astronomy and Medical Imaging

When we think of astronomy and medical imaging, we might not see many similarities between the two fields. However, a fascinating TED Talk by an astronomer and medical imaging expert revealed that there is a surprising overlap between the two areas of study.

The speaker shared a story of how astronomy research on the supernova remnant Cassiopeia A led to novel discoveries about how supernovas explode and how shells explode within them, using a piece of medical imaging software called 3DSlicer. This software was initially developed for looking at patients’ brain scans, doing surgical planning and 3D renderings of anatomy. It turns out that the way data comes from telescopes and medical imaging machines is remarkably similar.

For example, the raw data from an MRI scanner goes in slices, progressing from the patient’s nose to their eyes and cortex, then to the back of the brain. Telescopes operate in a similar manner, with raw data stepping back from the front of the nebula toward the middle and then the back, just like the middle and back of the patient’s brain.

By sharing technology and collaborating across fields, astronomers and medical professionals have been able to make new discoveries, transform how heart diagnostics are done, and even find new stars and supernova remnants. This highlights the importance of interdisciplinary collaboration and the potential benefits it can bring.

The Story of How Supernova Research Led to Medical Breakthroughs

The speaker shared a personal experience where they were able to help an astronomy colleague who was struggling to understand the 3D structure of the supernova remnant Cassiopeia A. The colleague had over eight years of magnificent data but no way to view it. By looking at the data with the speaker, they were able to create a rough draft of the nebula’s 3D structure, leading to novel discoveries about how supernovas and shells explode within them.

This breakthrough was made possible by a piece of medical imaging software called 3DSlicer. This software was developed for looking at patients’ brain scans, doing surgical planning, and 3D renderings of anatomy. The similarity between the data collected from medical imaging machines and telescopes made it possible for the speaker and their colleague to make these new discoveries.

The speaker also demonstrated a game called “Which is Which?” where they showed two images on the screen, one biomedical and one astronomical. The game highlighted how similar the images could appear and the surprising overlap between the two fields.

The speaker’s story demonstrates the importance of interdisciplinary collaboration and the potential for discoveries to be made when we share technology and knowledge across fields. It also highlights the role of innovation in making progress, where using medical imaging technology for astronomical research and vice versa allowed for new discoveries and advances in both fields.

The Similarities Between Astronomy and Medical Imaging

Although astronomy and medical imaging may seem like vastly different fields, there are surprising similarities between the two areas of study. The speaker demonstrated this by showing two sets of images, one biomedical and one astronomical, and asking the audience to identify which was which. The images were often difficult to tell apart, highlighting the overlap between the two fields.

One example of this overlap is the way data comes from medical imaging machines and telescopes. For instance, an MRI scanner acquires data in slices, progressing from the patient’s nose to their eyes and cortex, then to the back of the brain. Telescopes also operate in a similar manner, with raw data stepping back from the front of the nebula toward the middle and then the back, just like the middle and back of the patient’s brain.

The speaker also discussed the similarity between the tools used in both fields. Medical imaging software, such as 3DSlicer, was initially developed for looking at patients’ brain scans, doing surgical planning, and 3D renderings of anatomy. Similarly, astronomers use tools like OsiriX, a radiology toolkit, to view 2D and 3D renderings of astronomical data.

The similarities between astronomy and medical imaging demonstrate the potential for interdisciplinary collaboration and the importance of sharing knowledge across fields. By working together and using tools and technology developed for different purposes, scientists can make new discoveries and advancements in their respective fields.

The Game of “Which is Which?” between Biomedical and Astronomical Images

During the speaker’s presentation, they played a game called “Which is Which?” with the audience, showing two sets of images and asking them to identify which was biomedical and which was astronomical. The images were often difficult to distinguish, demonstrating the surprising similarities between the two fields.

For instance, one set of images showed the raw data of the supernova remnant Cassiopeia A on the left and an angiogram of a patient’s heart and coronary arteries on the right. Another set of images featured a confocal microscopy image of a human cornea and a radio telescope image of the star-forming region NGC-1333.

The speaker noted that aside from the fact that the images looked similar, the way the data comes from the machines and telescopes is also remarkably similar. Telescopes and particularly radio telescopes operate in a similar manner to medical imaging machines, acquiring data in slices that step back from the front to the middle and then to the back.

The game of “Which is Which?” highlights the similarities between astronomy and medical imaging and shows that the tools and techniques used in both fields are interchangeable. By utilizing interdisciplinary collaboration and sharing knowledge across fields, scientists can continue to make groundbreaking discoveries and advancements in their respective fields.

MRI Scans and Radiotelescopes: A Surprising Similarity

The speaker in the video highlighted a surprising similarity between MRI scans and radiotelescopes, two seemingly unrelated technologies used in medical imaging and astronomy, respectively.

When an MRI scanner acquires data, it goes in slices from the front to the back of the patient’s brain. Similarly, radiotelescopes acquire data in slices from the front to the middle and then to the back of the target object, such as a nebula.

By looking at the raw data from both machines, the speaker demonstrated how they progress from the nose and eyes to the middle of the head and then to the back of the brain or nebula. This similarity in the way data is acquired is remarkable and underscores the overlap between these two fields.

Although doctors use the acquired data to perform surgical planning and 3-D renderings of anatomy, astronomers use it to understand the 3-D structure and momentum in the universe. This similarity in the tools and techniques used in both fields provides an opportunity for interdisciplinary collaboration and sharing of knowledge.

By leveraging this overlap, scientists and researchers can unlock new discoveries and transform how we do heart diagnostics, analyze data for different patients, and organize and data mine it. The speaker’s work in interdisciplinary collaboration serves as a reminder of the importance of looking beyond one’s own domain and collaborating across borders to make groundbreaking discoveries.

Using Medical Technology for Astronomy and Astronomy Technology for Medicine

The collaboration between astronomy and medical imaging has led to a mutual exchange of technology and techniques that has transformed both fields. Medical technology has been used to study the universe, while astronomical technology has been used to diagnose and study diseases.

One example of this exchange is the Multiscale Hemodynamics Project, which uses a blood flow simulation originally developed for studying DNA structure and visualization tools developed for physics simulations to create a novel way of diagnosing heart disease. By collapsing the whole artery into a 2D plane using a tree diagram, doctors can efficiently diagnose high-risk, dangerous regions of the coronary arteries. This technique was inspired by astronomy, where tree diagrams are used to understand the structure of nebulae.

Another example is the use of the 3DSlicer software, originally developed for surgical planning and 3D rendering of anatomy, to study the 3D structure of supernova remnants. This software has allowed astronomers to make new discoveries about how supernovas and shells explode.

The exchange of technology and techniques between astronomy and medical imaging has opened up new avenues of research and discovery that would not have been possible without interdisciplinary collaboration.

The Multiscale Hemodynamics Project: A Novel Way of Doing Heart Disease Diagnostics

The project uses medical imaging technology to develop a new way of diagnosing heart disease that is less invasive than traditional angiography. The project also highlights the importance of interdisciplinary collaboration in medical research.

The project involves using a CT scan to visualize the coronary arteries, which are the arteries that wrap around the heart and can become blocked, leading to a heart attack. The scan is then color-coded to show blood flow simulations, which were originally developed for studying the structure of DNA. Visualization of the data was done with a toolkit called VisIt, which was originally developed for physics simulations.

The resulting 2D image of the artery was inspired by astronomy work, where tree diagrams were used to understand the structure of nebulae. The multiscale hemodynamics project collapsed the whole artery into a 2D plane, allowing doctors to quickly and efficiently identify high-risk regions that could block the artery and cause a heart attack. The project’s success in improving heart disease diagnostics shows how interdisciplinary collaboration can lead to groundbreaking medical breakthroughs.
