Questions & Answers

Q: How has the volume of medical data changed over time?

In the past, medical imaging machines generated around 100 images per scan, corresponding to about 50 megabytes of data. Now, they can produce 24,000 images in seconds, resulting in about 20 gigabytes of data or 800 phone books.

Q: What are some challenges in dealing with large medical datasets?

The challenge lies in processing and extracting relevant information from gigabytes or terabytes of data. It requires advanced algorithms and graphics processing units to handle the vast amount of data and visualize the desired structures, such as the heart or blood vessels.

Q: How are virtual autopsies conducted using medical imaging technology?

Virtual autopsies involve scanning the entire body using a CT scanner, generating a full-body dataset. Radiologists, pathologists, and forensic scientists analyze the data to determine the cause of death and aid criminal investigations. This approach avoids invasive physical autopsies and provides detailed visualizations of injuries and internal structures.

Q: What are some future applications of medical imaging technology?

Touch-based interaction with medical data, using devices with force feedback, can provide a hands-on experience for doctors to explore and examine anatomical structures. Additionally, functional MRI allows for mapping brain activity and real-time visualization, providing insights into brain functions and potential applications in neuroscience research.

Summary & Key Takeaways

  • Medical imaging machines, like CT scanners, generate enormous amounts of data, from 100 images in the past to now 24,000 images in just a few seconds, creating a data explosion in healthcare.

  • Extracting relevant information from gigabytes or terabytes of data is a challenge, but the use of graphics processing units (GPU) and algorithms has enabled the processing and visualization of medical data.

  • Virtual autopsies and touch-based interaction with medical data are emerging applications that allow for improved analysis and understanding of the human body.
