ISDI Sensor Instructions

General Sensor Configuration

  • Base Configuration is 14 x 1 Bit
  • Resolution is 1030 x 1536 pixels
  • For selecting pixel rows in centre: Use horizontal offset (ignore DVAL to activate field) and horizontal resolution

Increase number of frame buffers

  • To increase the number of frame buffers to the allowed maximum, start XCAP as administrator.
  • Select Capture/Sequence Capture/Video to Frame Buffers/Driver Assistant
  • Tick box in left field, then set number of frame buffers here.

Serial Terminal instructions for ISDI sensor

  • Find serial terminal in PIXCI(R) tab of sensor control software.
  • In Controls/Options: Make sure "Send string with CR" is selected. Should be default.
  • In Controls/Setup: Select Serial Port: Enabled. Baud rate has to be 115200
  • Set low full well mode using W000300000
  • Set high full well mode using W000300004
  • Read full well mode using R0003

Continuous Field buffer setting

  • This setting makes sure that the buffer is filled with a new frame as they come in. If this option is not selected the sensor and software will not be synchronised and we *will record a lot of pitch black images.
  • Select Capture/Live Options//Live Mode/Live Video: Continuous All buffer capture

Experiment Plan

  • Shoot-through measurements (back & front) for light calibration and level setting.
  • Range measurements between 70-120 MeV with 1mm steps with CMOS sensor and photodiodes.
  • High intensity range measurements between 70-120 MeV with 1mm steps with photodiodes at optimal light level.
  • Live measurement of 3cm x 3cm x 3cm treatment plan.
