In vivo EBT radiochromic film dosimetry of electron beam for Total Skin Electron Therapy (TSET)

Radiochromic film dosimetry: Past, present, and future

“…Radiochromic film shows a great potential for two dimensional clinical dosimetry of electron beams [51,52], and has been found useful in total skin electron therapy (TSET): Bufacchi et al [53] used the EBT film to measure dose during TSET in vivo, while Lightfoot [54] and Reinard [55] described the use of the same film model for a TSET commissioning process as indicated in Fig. 7c.…”

Assessment of clinically relevant dose distributions in pelvic IOERT using Gafchromic EBT3 films

“…A good setup is crucial to obtain good results, particularly near the surface where the air gap effect is greater. Nevertheless, some authors have reported good results with films, both perpendicular [20] and parallel to the beam, using conventional [19] and circular [21] electron beam applicators, as well as degraded beams far from the source [22].…”

Response of EBT3 Gafchromic films exposed to high energy electrons

“…The average pixel values (PV) were determined in a region of interest of 2x2 cm 2 using ImageJ software. When radiochromic films are digitized on a flat scanner, the optical density is defined as (2) where PV unexp and PV exp are the average of pixel values measured for unexposed and exposed films, respectively.…”
