AR Puncture: Medical AR Viewer

- AR Puncture is a free navigation app using augmented reality (AR) on smartphones to simulate needle puncture and surgery (for research purposes and experiments). 
- 3D organ models (FBX, OBJ, STL) can be easily imported and placed from your mobile phone’s folder without pre-processing. The position, size, and color can be easily adjusted. 
- A 3D virtual protractor or a target positioned relative to an entry point for needle puncture using the Bull's eye method can be also easily displayed.
- Three registration methods are available (Fix On Screen, Tap To Place, or QR Tracking). In the initial mode (Fix On Screen mode), the center of the 3D model / entry point is always displayed at the center of the screen, which can be adjusted to the real entry point or merkmal by moving the device. In the Tap To Place mode, it is placed at the tapped position. In the QR Tracking mode, it is placed on the dedicated QR code, which is downloaded and printed in advance (see below). 
- The protractor can be rotated in 3 directions against the CT plane. 
- The target can be placed relative to the entry point by inputting data from the CT images. 
- “MR Puncture” for HoloLens2 has similar functions partially to this application.
