Download scientific diagram | | Schematic overview over different postures. A straight upright posture [e.g (42)., and (31)] has been noted to induce stress on chin (for head&neck patients) and may be uncomfortable for long treatment duration, as indicated by the red areas. More ideal would be ~20° reclined position, where the forward push on the pelvis could be stabilized by a race-car seat posture [e.g (9)], or by adding a knee fixation [e.g (8)] or a belt strap [e.g (35)]. Alternative postures could be forward leaning for head&neck or possibly spine irradiations [e.g (26)] or half-standing, enabling to image and treat sites below the thorax [e.g (8)]. from publication: Considerations for Upright Particle Therapy Patient Positioning and Associated Image Guidance | Particle therapy is a rapidly growing field in cancer therapy. Worldwide, over 100 centers are in operation, and more are currently in construction phase.
