Surface-Guided Radiation Therapy

Each year, 27,000 new cases of cancer are being diagnosed in British Columbia and approximately 10,000 people will undergo radiation therapy at BC Cancer.

Radiation therapy uses high energy beams to kill cancer cells and stop them from growing and reproducing. This procedure requires a high degree of accuracy.

At the moment, to ensure accuracy in delivering radiation therapy to patients, small marks are tattooed on the patient’s skin to pinpoint the treatment area. Although the tattoos are small, applying them can be painful and the process is permanent.

Children who are especially “wiggly” undergo sedation to prevent movement; sedation comes with side effects and the long procedure requires the expertise of specialized pediatric anesthesia.

A real-time optical surface monitoring system is urgently needed to enable guided tracking for radiation therapy at BC Cancer – Vancouver, resulting in:

  • More accurate treatment delivery

  • Improved patient comfort and safety

  • Reduced number of treatment times

Real-time optical surface monitoring may eliminate the need for:

  • Immobilization devices which will keep patients still during treatment

  • Permanent tattoos which mark the radiation targets on patients’ skin

  • Patient sedation

每年在卑詩省診斷出27,000新癌症病例,約有一萬人因患上癌症要在卑詩癌症中心(BCCANCER)接受放射治療。

此種輻射治療法,是用高能度射線去殺死癌細胞, 並可阻止其繼續生長和繁殖。此治療法的過程,是需要高度的準確性,才能達到其效果,给與患癌者可獲重生的機會。

目前,為了確保向患者提供此高度放射治療的準確性,在患者皮膚刻上一個小痕跡,以確認需要治療的癌細胞區域。儘管一個细小的紋身方法,但紋身過程中可能會很痛楚,而且此過程是永久性的傷害。

當癌症患者是一位兒童而因小朋友的“搖擺不定”個性,這樣提高了難度而影响治療過程的準確性。為了使病童能安靜而順利接受治療過程,只好注射鎮靜藥物;但此鎮靜藥物會帶來副作用,因而影响病童的較佳康復機會。監於漫長的治療過程中,需要兒科麻醉專家協的協助下,因而加重了我們醫療服務的開支。

現今卑詩省迫切地需要一個實時光學表面監測系統,讓BC Cancer之温哥華癌症治療中心,可以進行放射治療的引導跟踪,從而提供

·更準確的治療法

·改善患者的舒適度和安全性

·減少治療次數

實時光學表面監測系統的治療效果

·固定裝置,可使患者在治療過程中保持靜止

·永久性紋身,標記患者皮膚上的輻射目標

·病人的鎮靜
