Components | 6-voxel prototype ($) | 64-voxel imager ($) | 1024-voxel imager ($) |
---|---|---|---|
Sensors, coils | 428 | 1705 | 6820 |
Amplifiers, DAC, ADC* | 2833 | 411 | 1644 |
Resistors, capacitors | 59 | 263 | 1052 |
Adapters, boards, power supply, misc. | 285 | 634 | 2536 |
Controller* | 2775 | 46 | 234 |
Total | 6380 | 3059 | 12286 |
Lower cost chip-based ADC and controller components are specified for the 64-voxel and 1024-voxel systems instead of the more costly general purpose NI-USB 6289 used in the current 6-voxel prototype.
