You probably don’t think much about medical scan data. But they’re everywhere. If you’ve got an X-ray or an MRI, your images were almost certainly processed by DICOM (Digital Imaging and Communications in Medicine), the globally accepted standard for storing and sharing medical imaging data like X-rays, MRIs, and CT scans between hospitals, clinics, and research institutions since the late 80s and early 90s. But there’s a problem: while medical technology has made incredible leaps in the last 30 years, DICOM hasn’t kept up. What is DICOM anyway? DICOM still operates in ways that feel more suited to a 1990s environment of local networks and limited computing power. Despite updates, the system doesn’t meet the demands of cloud computing, AI-driven diagnostics, and real-time collaboration. It lacks cloud-native support and rigid file structures, and shows inconsistencies between different manufacturers. If your doctor still hands you a CD with your scan on it in 2025 (!), DICOM is a big part of that story. The DICOM Legacy How DICOM Came to Be When DICOM was developed in the 1980s, the focus was on solving some big problems in medical imaging, and honestly, it did the job brilliantly for its time. The initial idea was to create a universal language for different hardware and software platforms to communicate with each other, sort of like building a shared language for technology. They also had to make sure it was compatible with older devices already in use. At that time, the most practical option was to rely on local networks since cloud-based solutions simply didn’t exist yet. These decisions helped DICOM become the go-to standard, but they also locked it into an outdated framework that’s now tough to update. Why It’s Hard to Change DICOM Medical standards don’t evolve as fast as consumer technology like phones or computers. Changing something like DICOM doesn’t happen overnight. It’s a slow and complicated process muddled by layers of regulatory approvals and opinions from a tangled web or organizations and stakeholders. What’s more, hospitals have decades of patient data tied to these systems, and making big changes that may break compatibility isn’t easy. And to top it all off, device manufacturers have different ways of interpreting and implementing DICOM, so it’s nearly impossible to enforce consistency. The Trouble With Staying Backwards Compatible DICOM’s focus on working perfectly with old systems was smart at the time, but it’s created some long-term problems. Technological advancements have moved on with AI, cloud storage, and tools for real-time diagnostics. They have shown immediately how limited DICOM can be in catching up with these innovations. Also, vendor-specific implementations have created quirks that make devices less compatible with one another than they should be. And don’t even get started on trying to link DICOM with modern healthcare systems like electronic records or telemedicine platforms. It would be like trying to plug a 1980s gadget into a smart technology ecosystem — not impossible, but far from seamless. Why Your CT Scanner and MRI Machine Aren’t Speaking the Same Language Interoperability in medical imaging sounds great in theory — everything just works, no matter the device or manufacturer — however, in practice, things got messy. Some issues sound abstract, but for doctors and hospitals, they mean delays, misinterpretations, and extra burden. So, why don’t devices always play nice? The Problem With “Standards” That Aren’t Very Standard You’d think having a universal standard like DICOM would ensure easy interoperability because everybody follows the same rules. Not exactly. Device manufacturers implement it differently, and this leads to: Private tags. These are proprietary pieces of data that only specific software can understand. If your software doesn’t understand them, you’re out of luck. Missing or vague fields. Some devices leave out crucial metadata or define it differently. File structure issues. Small differences in how data is formatted sometimes make files unreadable. The idea of a universal standard is nice, but the way it’s applied leaves a lot to be desired. Metadata and Tag Interpretation Issues DICOM images contain extensive metadata to describe details like how the patient was positioned during the scan or how the images fit together. But when this metadata isn’t standardized, you end up with metadata and tag interpretation issues. For example, inconsistencies in slice spacing or image order can throw off 3D reconstructions, leaving scans misaligned. As a result, when doctors try to compare scans over time or across different systems, they often have to deal with mismatched or incomplete data. These inconsistencies make what should be straightforward tasks unnecessarily complicated and create challenges for accurate diagnoses and proper patient care. File Structure and Storage Inconsistencies The way images are stored varies so much between devices that it often causes problems. Some scanners save each image slice separately. Others put them together in one file. Then there are slight differences in DICOM implementations that make it difficult to read images on some systems. Compression adds another layer of complexity — it’s not the same across the board. File sizes and levels of quality vary widely. All these mismatches and inconsistencies make everything harder for hospitals and doctors trying to work together. Orientation and Interpretation Issues Medical imaging is incredible, but sometimes working with scans slows things down when time matters most and makes it harder to get accurate insights for patient care. There are several reasons for this. Different Coordinate Systems Sometimes, DICOM permits the use of different coordination systems and causes confusions. For instance, patient-based coordinates relate to the patient’s body, like top-to-bottom (head-to-feet) or side-to-side (left-to-right). Scanner-based coordinates, on the other hand, are based on the imaging device itself. When these systems don’t match up, it creates misalignment issues in multi-modal imaging studies, where scans from different devices need to work together. Slice Ordering Problems Scans like MRIs and CTs are made up of thin cross-sectional images called slices. But not every scanner orders or numbers these slices in the same way. Some slices can be stored from top-to-bottom or bottom-to-top. If the order…

Introduction Virtual and mixed reality headsets are not just cool toys to show off at parties, though they’re definitely good for that. They train surgeons without risking a single patient, build immersive classrooms without ever leaving home, and even help to design something with unparalleled precision. But choosing VR/MR headsets … It’s not as simple as picking what looks sleek or what catches your eye on the shelf. And we get it. The difference between a headset that’s wired, standalone, or capable of merging the real and digital worlds is confusing sometimes. But we’ll break it all down in a way that makes sense. Types of VR Headsets VR and MR headsets have different capabilities. However, choosing the perfect one is less about specs and more about how they fit your needs and what you want to achieve. Here’s the lineup… Wired Headsets Wired headsets like HTC Vive Pro and Oculus Rift S should be connected to a high-performance PC to deliver stunningly detailed visuals and incredibly accurate tracking. Expect razor-sharp visuals that make virtual grass look better than real grass and tracking so on-point, you’d swear it knows what you’re about to do before you do. Wired headsets are best for high-stakes environments like surgical training, designing complex structures, or running realistic simulations for industries like aerospace. However, you’ll need a powerful computer to even get started, and a cable does mean less freedom to move around. Standalone Headsets No strings attached. Literally. Standalone headsets like Oculus Quest Pro, Meta Quest 3, Pico Neo 4, and many more) are lightweight, self-contained, and wireless, so you can jump between work and play with no need for external hardware. They are perfect for on-the-go use, casual gaming, and quick training sessions. From portable training setups to spontaneous VR adventures at home, these headsets are flexible and always ready for action (and by “action”, we mostly mean Zoom calls in VR if we’re being honest). However, standalone headsets may not flex enough for detailed, high-performance applications like ultra-realistic design work or creating highly detailed environments. Mixed Reality (MR) Headsets Mixed reality headsets blur the line between physical and digital worlds. They don’t just whisk you to a virtual reality — they invite the virtual to come hang out in your real one. And this means holograms nested on your desk, live data charts floating in the air, and playing chess with a virtual opponent right at your dining room table. MR headsets like HoloLens 2 or Magic Leap 2 shine in hybrid learning environments, AR-powered training, and collaborative work requiring detailed, interactive visuals thanks to their advanced features like hand tracking and spacial awareness. MR headsets like HoloLens 2 or Magic Leap 2 shine in hybrid learning environments, AR-powered training, and collaborative work requiring detailed, interactive visuals thanks to their advanced features like hand tracking and spacial awareness. The question isn’t just in what these headsets can do. It’s in how they fit into your reality, your goals, and your imagination. Now, the only question left is… which type is best for your needs?
