Misc info from:


Faxitron X-Ray DX-50 Digital Biopsy System with Option DC-4 Specimen Radiography

The Faxitron MX-20 Digital Specimen Radiography System is substantially

equivalent to the following to the following predicate devices:

Faxitron Micro 50 Specimen Radiography System-K852634

Faxitron DX-50 Digital Radiography System-K061361

MX-20 510(k) Submission

piXarray Digital Specimen Radiography System-K052433

"The USB Hamamatsu 120mm x 120mm camera array cost £25K on top of the basic MX-20 cabinet cost of £25K. Scary prices." https://www.eevblog.com/forum/buysellwanted/(uk)-faxitron-mx-20-120mm-x-1200mm-complete-system-frasers-own-unit/msg2355963/#msg2355963

  • Very detailed and valuable info
  • See for manuals and other info

Weight

  • DX-50 sample shipping weight w/ box: 67 lb
  • DX-50 w/ computer: about 81 lb


Circa 2008

  • Hammimatsu flat panel detector
  • Carbon fiber x-ray window to sensor

Manual option info

  • DC2: Dalsa, CCD type. 50 x 50 mm (2" x 2") field of view.
  • DC4: Dalsa, CCD type. 50 x 100 mm (2" x 4") field of view.
  • DC22: Bioptics, CMOS type. 50 x 50 mm (2" x 2") field of view.
  • DC24: Bioptics, CMOS type. 50 x 100 mm (2" x 4") field of view.
  • DC44: Bioptics, CMOS type. 100 x 100 mm (4" x 4") field of view.
  • DC3: Hamamatsu, CCD type. 24 x 34 mm (0.94" x 1.3") field of view.
  • DC5: Hamamatsu C9730DK-11, CMOS type. 50 x 50 mm (2" x 2") field of view.
  • DC10: Hamamatsu, CMOS type. 100 x 100 mm (4" x 4") field of view.
  • DC12: Hamamatsu C9732DK, CMOS type. 120 x 120 mm (4.7" x 4.7") field of view.

Power supply

The original power supply is roughly:

  • 12V in?
  • Dual channel
  • Power-one DGP12U5D5, WTT250IG
    • Outputs +/- 5V
    • Is the -5V rail used?
    • Seem to output 5.3 or 5.4V
  • LM317
  • So basically: 12V DC is converted to just above 5V. Then a linear regulator smooths the last remaining bit down to 5V

Perkin-elmer_xrd-1640_an19-ets-lp

"The MX-20 had an Perkin Elmer panel sensor with parallel output to an SCSI PC interface board. It can do medium sized boards, up to 10" x 12"...The P-E sensor that came with my MX-20 was not it's original sensor. My MX-20 was non-digital, just a film based one (or phosphor plate based). The P-E had a low voltage differential, parallel, output that was sent through a cable to a PCI frame capture board. The board (made by Perkin Elmer) looked like a SCSI interface to the PC. The sensors are available on eBay, sometimes for a good price, but I've not seen a complete system, sensor, power supply, cables, interface card, and software, in a long time. A sensor is on eBay now, see"
