Blu Tray

Isoray’s Blu Tray delivery system empowers clinicians by organizing and measuring Cesium Blu Strands while in the OR. The custom designed, shielded, stainless steel tray organizes strands for clinicians who pre-plan cases or those that prefer to do real-time dosimetry and modify strands in the OR. Blu Tray is a modern tool for today's brachytherapist.

Modern brachytherapy starts here.

Not all brachytherapy radioisotopes are the same. Cesium Blu, Cs-131, offers you a powerful option for treating prostate and other cancers throughout the body.

Higher Energy

Isoray’s proprietary isotope, Cesium Blu, has a higher energy allowing for a more uniform dose distribution with less overdosing than other permanent isotopes. (1)

Shorter Half-Life

Isoray’s proprietary isotope, Cesium Blu, has a shorter half-life than other commonly used isotopes for the treatment of cancer throughout the body, resulting in a shorter duration of radiation which contributes to a rapid resolution of patient side effects. (2)

Improved Coverage of the Prostate

Isoray’s Cesium Blu proprietary permanent prostate cancer brachytherapy seeds allow for better dose homogeneity and the sparing of the urethra and rectum while providing comparable prostate coverage compared to other seeds with comparable or fewer seeds and needles. (3, 4, 5, 6)

Rapid Resolution of Side effects

Isoray’s proprietary isotope, Cesium Blu, has a shorter half-life than other commonly used isotopes for the treatment of cancer throughout the body, resulting in a shorter duration of radiation which contributes to a rapid resolution of patient side effects. (7, 8, 9, 10)

Higher Biologically Effective Dose

Isoray’s Cesium Blu also delivers a higher “biological effective dose” or BED compared to I-125 or Pd-103 across a wide range of tumor types. (11)

PSA Control

Isoray along with investigators tracking PSA in both single arm and randomized prostate cancer treatment trials have concluded that Cesium Blu’s PSA response rates have similar early tumor control to I-125, which was previously considered the gold standard in permanent seed brachytherapy. (8, 12, 13)

Your Isotope Choice Makes a Difference

Cesium Blu

Introduced in 2004

  • 9.7 Day Half-Life

  • The amount of time for the radiation to half. A shorter half life means quicker to PSA baseline. (8, 12, 13)

  • 30.4 Kev

  • The energy level of the isotope. Higher energy leads to greater coverage of the infected organ.

  • 33 Days for 90% Dose

  • Faster dose delivery rate.

  • Detectable in the body for 97 Days

Paladium-103

Introduced in 1986

  • 17 Day Half Life (18)

  • 20.8 Kev

  • 58 Days for 90% Dose

  • Detectable in the body for 170 Days

Iodine-125

Introduced in 1965

  • 60 Day Half Life (18)

  • 28.5 Kev

  • 204 Days for 90% Dose

  • Detectable in the body for 600 Days
