Tong 4 3D Image Guided Surgery, 3D Robotic & Laparoscopic Surgery Flashcards
What do a Da Vinci Robotic system consist of?
- patient-side cart
- 2D LCD display
- image processing unit
- 3D operative console
- robotic arm with 7 degree of freedoms
- a pair of optical fibre for 3D vision
- high precision surgical tools
Typically how many arms are there for Da Vinci Robotic system?
4 robotic arms
3 for tools and 1 for vision
What are the benefits of Da Vinci Robotic system for patients
- minimally invasive
- less pain
- less blood loss
- reduce need for blood transfusions
- shorter hospital stays
- quicker recovery
How Da Vinci Robotic system improves surgeons hand movements?
- exceed natural range of motion
- reduce motion scaling and tremor
What are current limitation of Da Vinci Robotc system?
- only the operator is able to access to high precision 3D viewing
- assistants and nurse cannot appreciate the 3D viewing
- trainers and trainees cannot appreciate the 3D difficulties in training
What are the features of stereoscopic visualization system for robotic surgery?
- real time and high resolution
- for facilitating robotic surgical support
- training in the operation theatre and lecture room settings
What are the design parameters of he stereoscopic visualization system?
- 30frames per second
- resolution = 1920 x 1080
- two close distanced camera
- high magnifications
- multiple displays
- light-weighted passive stereoscopic glasses for long hour wearing
What are sub-pixels?
Contained in a pixel, red, green and blue
What is horizontal interlacing?
The odd number line and even number lined are displayed separately by left and right eye display to produce a live 3D vision when using passive stereo glasses.
One row of pixels form the left camera and one row of pixel from the right camera
What are the hardware requirement of 3D stereoscopic visualization system for its high computation requirement ?
- Intel i7 at 60,000 MIPS with 4 cores
- 4 GB RAM
- window 1064 bit
- no memory leakage is allowed
- video capturing at a speed of 30 fps for two video resolution (1920 x 1080 pixels in colour)
