23374: Real-Time Scanning with Jetson TX For Skin Cancer Detection Michael Gielda Jeremy Massey Antmicro Iko Business Development Manager Director
1 Skin Cancer
Most common form of cancer.
! Skin Cancer Rates
Types of skin cancer include: Basal Cell Carcinoma (BCC) • Squamous Cell Carcinoma (SCC) • Malignant Melanoma (MM) •
Malignant Melanoma Comparatively rare form. Highest mortality rate.
Detect it early! Early surgical intervention is cheap and almost 100% effective.

Device Requirements Real-time 3D point cloud registration. • Real-time 2D de-mosaicing. • Real-time 3D mesh generation. •
CUDA & Jetson TX Requirements are well suited to parallel processing and the NVIDIA Jetson TX is perfectly suited for the task.
Features Data acquisition, display & storage: Depth and colour camera • connected to NVIDIA Jetson TX1/2 module. SD card for storage. • 5” LCD with capacitive touch • screen for UI. Communication: WiFi Connectivity • Wired Ethernet • Debugging via USB UART, OTG •
Getting the Vision / 3D Data PixeLink camera for colour data. • (Liquid lens!) RealSense SR300 for depth data. •
Challenges for Developing the Hardware Compactness • Easy Handling • Camera Integration • Heat Dissipation •
Compactness Making the device portable and reducing overall weight. Dealing with spatial • arrangement between cameras and lighting. Battery placement -> serving • as a hand grip. Placement of the display. •
Easy Handling Plexiglass construction makes (dis)assembling the prototype easy. Fully usable in field testing • while fastened. Particular sections of PCB • accessible for debugging. Convenient dismantling for • hardware maintenance.
Camera Integration USB-FFC adapter board for more robust work with USB 3.0 connectors.
Heat Dissipation Lots of heat sources – heat dissipating aluminum frame.

Current methods of analysing and monitoring moles are labour intensive making them expensive.
Acquisition process has been reduced from potentially hours to a few minutes.
System designed with relatively low cost hardware.
