Two gamma camera systems were used: Picker IRIX system (Marconi, Philips, Holland) and Millennium VG Hawkeye system (General Electric Medical Systems, Milwaukee, WI, USA), both equipped with medium energy parallel-hole collimators.
The gamma cameras were a Picker IRIX (Marconi, Phillips, Holland) and a Millennium VG Hawkeye (General Electric Medical Systems, Milwaukee, WI, USA) equipped with medium energy parallel-hole collimators.
A whole-body iodine scan and single-photon emission computed tomography (SPECT) were performed four to seven days after ablative 131I administration using a double-headed Toshiba 7200 A/UI gamma camera (Toshiba Medical Systems, Nasu, Japan) equipped with high energy parallel-hole collimators.
A collimator for the parallel dual-energy X-ray beam was designed to minimize X-ray beam interference between low- and high-energy parallel beams for 500 mm source-to-detector distance.
For dosimetry, patients were scanned with a large field of view dual head gamma camera (BIAD, Trionix, Twinsburg, Ohio, or Prism 2000, Picker) equipped with high-energy parallel collimators and using a matrix of 1024 × 256.
The rabbits were positioned 2 cm directly below a medium-energy parallel-hole collimator [1].
The gamma camera used for generating planar and SPECT/CT images was a Millennium VG Hawkeye (General Electric Medical Systems, Milwaukee, WI, USA), equipped with a medium-energy parallel-hole collimator.
A medium-energy parallel-hole collimator is used.
All images were acquired on dual-headed gamma cameras using medium-energy parallel-hole collimators.
