CUDA實現栩栩如生的胎兒3D超音波成像, 還支持立體眼鏡觀賞
現在這產品 (叫做 syngo.fourSight Workplace) 已經出貨了, 我們聯絡產品開發部門的協理, Roee博士, 看看有什麼進一步的消息. 以下是我們訪談的內容:
NVIDIA: Roee, 恭喜您的產品已經開始出貨. 想請教你, 您如何用CUDA將超音波成像提升到另一個技術層次的?
Roee: 這是世界上第一個在市場上發行的, 將超音波影像變成3D影像, 還支持立體眼鏡觀看的產品. 這是一大創舉, 它提供醫生與病患解剖學上的資訊, 以進行產前與產後的手術規劃.
NVIDIA: 這技術同時使用了以CUDA為基礎的NVIDIA Quadro FX圖形處理器, 與NVIDIA 3D Vision 3D幻鏡技術. 可以說說看為何3D立體技術對這應用來說是重要的?
Roee: 當大量的3D資訊被投放在"平面的”顯示器上時, 我們很難分辨解剖學上的細節與影像的深度, 例如骨骼的彎曲程度等等. 用立體眼鏡觀察超音波成像是較直覺的方式.
NVIDIA: 您的技術提到”3D/4D”, 請問這是什麼意思?
Roee: 3D指的是具有靜態體積的圖像(3維影像的靜態平面投放圖像). 我4D指的是可動態觀賞的體積圖像, 例如用來觀察胎兒的肢體運動或臉部表情.
NVIDIA: 這樣的技術還能應用在哪些地方?
Roee: 不只用在胎兒成像, 從心臟器官搏動到腹腔內所有器官都可以用動態的體積圖像來觀察, 這表示我們可以從各種視角重建身體組織. 這個技術在醫療診斷與醫病雙方的溝通上, 有很令人興奮的潛力.
This week Siemens Healthcare announced availability of its next-generation 3D/4D ultrasound software which produces realistic, vivid images of a fetus. When we saw Dr. Roee Lazebnik of Siemens demo this at CUDA Day last February, we frankly were amazed by it.
Now that the product (called syngo.fourSight Workplace) is shipping, we contacted Roee, director of product development, for an update. Here's an excerpt from our interview:
NVIDIA: Roee, congratulations on the release. How does this technology take ultrasound to the next level?
Roee: This is the world's first commercially-available product for stereoscopic visualization of ultrasound data. It's a breakthrough because it provides anatomical information that can enable better communication between physicians and patients and aid in pre- and post-natal surgical planning.
NVIDIA: The technology leverages CUDA-based NVIDIA Quadro FX solutions as well as NVIDIA 3D Vision. Why is the 3D functionality important?
Roee: When we interact with volumetric data on a 2D screen, our ability to appreciate anatomical subtleties and depth-based details, such as the curvature of a skeletal feature, is limited. It is much more intuitive to visualize 3D data in stereo.
NVIDIA: The technology is described as "3D/4D." What does that mean?
Roee: 3D involves visualizing a static volumetric image. The term 4D refers to visualizing dynamic anatomy, such as the moving limbs or facial gestures of the fetus.
NVIDIA: In what other ways could this technology be applied in the future?
Roee: In the human body, everything from the beating heart to the abdomen can be visualized in a volume mode, meaning it can be reconstructed and viewed from any orientation. This technology has many exciting potential benefits both in diagnosis and visual communication of findings.
