What was measured?
The acoustic and vibrational signals recorded by a needle-mounted microphone during Dobot MG400 controlled insertions at three constant speeds through two layered phantom configurations:
Phantom 1 (chicken over zucchini):
- Chicken layer: ~1.95–2.00 cm
- Zucchini layer: ~1.96–2.00 cm
- Gel base: ~2.00 cm
- Total insertion depth: 6.5 cm (Dobot Z: –20 mm to –85 mm)
Phantom 2 (zucchini over chicken):
- Zucchini layer: ~2.35–2.50 cm
- Chicken layer: ~1.90–2.30 cm
- Gel base: ~1.50 cm
- Total insertion depth: 7.0 cm (Dobot Z: –20 mm to –90 mm)
In both setups, the needle tip was initially positioned 0.5 cm above the phantom surface.
Methods
Type of needle: 22G quincke bevel needle
Measurements were taken using Dobot Mg400 robot arm.
Needle Speeds
3 different speeds were used.
- Slow(12.17 mm/s)
- Medium(16.67 mm/s)
- Fast(23.53 mm/s). For all measurement needle tip was 0.5 cm above then surface of phantom. Thats mean needle moved in 6cm at both phantoms.
Phantoms
2 different phantoms were created - chicken and zucchini. 1st phantom has 0.6-0.9 cm top gel layer 2nd phantom has 0.7-1 cm gel top layer
