Real‐time in vivo dosimetry system based on an optical fiber‐coupled microsized photostimulable phosphor for stereotactic body radiation therapy

Abstract: Purpose: To develop an in vivo dosimeter system for stereotactic body radiation therapy (SBRT) that can perform accurate and precise real-time measurements, using a microsized amount of a photostimulable phosphor (PSP), BaFBr:Eu 2+. Methods: The sensitive volume of the PSP was 1.26 9 10 À5 cm 3. The dosimeter system was designed to apply photostimulation to the PSP after the decay of noise signals, in synchronization with the photon beam pulse of a linear accelerator (LINAC), to eliminate the noise signals com… Show more

“…Passive or active nanostructures can be created to specifically target a drug to remote regions of the body that are inaccessible for normal macromolecular drugs. For example, the novel fiber-optic dosimeter (nanoFOD) device based on nanomaterial is used to pinpoint and measure the in vivo radiation dose in real-time that was given during external beam delivery in radiation therapy sessions [173]. Furthermore, nanorobotics and molecular nanosystems can create artificial organs and system mimics have the potential to control the future of nanochemotherapy.…”

“…Ryuichi Yada et al developed an in vivo dosimeter measurement system using BaFBr:Eu 2+ phosphors. They investigated the angle dependence of the dosimeter over a range of incidence angles from 0°to 150°, and their measurements showed angle errors within 4% [18]. In recent years, Songke Yu et al investigated the non-equivalent differences between diamond scintillators and human tissues and proposed a conversion method based on the Chapman-Kolmogorov equation [19].…”

“…Driving factors for this include the small dimensions of optical fibre sensors, their immunity to electromagnetic interference, and general ease of achieving biocompatibility [ 2 , 3 ]. The aforementioned benefits are of particular advantage in radiotherapy linear accelerators [ 4 , 5 , 6 ], magnetic resonance imaging (MRI) devices [ 7 , 8 , 9 ], and general in vivo applications themselves [ 10 , 11 , 12 ]. In addition to the aforementioned patient-centric applications, high-resolution temperature sensors may also be of benefit in micro-volume calorimetry applications.…”
