A method for radiation therapy comprising imaging margins of a hydrogel spacer using ultrasound, wherein the hydrogel spacer is at a site between a first tissue location and a second tissue location to increase a distance between the first tissue location and the second tissue location, the site being chosen to decrease radiation at the first tissue location when the second tissue location receives a dose of therapeutic radiation, wherein the hydrogel spacer comprises a polysaccharide.
A method for radiation therapy comprising introducing a hydrogel spacer at a site between a first tissue location and a second tissue location using ultrasound, wherein the hydrogel spacer increases a distance between the first tissue location and the second tissue location, the site being chosen to decrease radiation at the first tissue location when the second tissue location receives a dose of therapeutic radiation, wherein the hydrogel spacer comprises a collection of covalently-crosslinked biodegradable hydrogel particles comprising a polysaccharide.
A method for radiation therapy comprising imaging a site of a hydrogel spacer comprising a collection of polysaccharide particles that is positioned between a first tissue location and a second tissue location using ultrasound, wherein the hydrogel spacer establishes a distance between the first tissue location and the second tissue location, the site being chosen to decrease radiation at the first tissue location when the second tissue location receives a dose of therapeutic radiation, wherein the hydrogel spacer further comprises a linear polymer in addition to the hydrogel particles.
A method for radiation therapy comprising imaging a site of a hydrogel spacer that is positioned between a first tissue location and a second tissue location using ultrasound, wherein the hydrogel spacer establishes a distance between the first tissue location and the second tissue location, wherein the hydrogel spacer comprises hydrogel particles, wherein the hydrogel particles comprise a glycosaminoglycan that is crosslinked with a reactive precursor species having electrophilic functional groups.
