    <p>Dear Karl,</p>
    <p>I ran into this problem earlier this year and created the
      attached drawing. For me it works, but no guarantee... Hope it
      helps anyhow.</p>

        <div>I was wondering if there is any place where the crystal
          numbering scheme (for example, that used in ASCII output) is
          laid out. I am simulating PET scanner which utilizes the ECAT
          architecture. It consists of 8 rings of 56 blocks, each of
          which contains an 8x8 crystal array. Is there a source that
          could explain how exactly these crystals are indexed?</div>
