Quantifying stent-induced dose perturbations in intravascular brachytherapy using 3D- printed phantoms and film dosimetry. [PDF]
J Appl Clin Med PhysAbstract Background Coronary artery disease (CAD), the leading cause of death worldwide, is the narrowing of coronary arteries due to atherosclerotic plaque buildup. A common treatment for CAD is percutaneous coronary intervention (PCI), often involving stent placement. However, a common complication or in‐stent restenosis (ISR) can occur in 10%–20% of

Dosimetric evaluation of breast radiotherapy treatments using magnetic valve expansion prostheses
Brazilian Journal of Radiation Sciences, 2022 This work intends to verify the influence on the dose distribution that the expansive prosthesis (SILIMED/470), containing a magnetic valve, generates in postoperative radiotherapy treatments of patients who underwent mastectomy.

3D printed collimators and dosimetry for spatially fractionated radiation therapy. [PDF]
J Appl Clin Med PhysAbstract Background Spatially fractionated radiation therapy (SFRT) has shown incredible potential in sparing normal tissues and activating mechanisms of tumor control distinct from conventional radiotherapy. However, the optimal spatial configuration of SFRT as well as the optimal peak and valley dose values have not been established.

Linear energy transfer-independent calibration of radiochromic film for carbon-ion beams
Physics and Imaging in Radiation Oncology, 2022 For carbon-ion beams, radiochromic film response depends on the dose and linear energy transfer (LET). For film dosimetry, we developed an LET-independent simple calibration method for a radiochromic film for specific therapeutic carbon-ion beams.

放射線エネルギーの違いによる喉頭癌における吸収線量の影響 [PDF]
, 2002 We investigated the usefulness of Gafchromic MD-55 film (Nuclear Associates, Inc.) for measuring the radiation doses on the radiotherapy of laryngeal cancers. Since larynx has thin wedge-shaped structure in anterior neck adjacent to airway, the radiation

Radiochromic film dosimetry in water phantoms [PDF]
Physics in Medicine and Biology, 2000 Radiochromic film is investigated for use in dosimetry in water phantoms as opposed to solid phantoms. Investigations are performed to measure the penetration rates of water into radiochromic film and to assess the effects on optical density that this penetration causes.
