Abstract :
We present an instrument for measuring the thickness of porcine xenografts used as temporary biological coverings in the treatment of extensive burn injuries. The instrument is based on PIN diode measurements of the attenuation of X-rays through the xenografts. The PIN diodes were developed as a joint project with CINVESTAV, Mexico. The instrument response to different X-ray energies was characterized and the electronic circuitry was optimized for reducing noise at low X-ray energies. The apparatus is accurate and reasonably priced. It substitutes alternate techniques that require to be in contact with the tissues.
