Treatment planning for high dose rate brachytherapy of cervical cancer based on total dose constraints.
OBJECTIVE To compare the inverse planning optimization based on total dose constraints versus conventional treatment plan (point A planning method) for cervical carcinoma, and evaluate the benefit of CT-based image-guided brachytherapy. METHODS We prospectively analyzed data of 10 consecutive patients with cervical cancer treated with external beam radiotherapy to the whole pelvis (45 Gy in 2...
متن کاملApplicator reconstruction in MRI 3D image-based dose planning of brachytherapy for cervical cancer.
BACKGROUND AND PURPOSE To elaborate a method for applicator reconstruction for MRI-based brachytherapy for cervical cancer. MATERIALS AND METHODS Custom-made plastic catheters with a copper sulphate solution were made for insertion in the source channels of MR-CT compatible applicators: plastic and titanium tandem ring applicators, and titanium needles. The applicators were CT and MR scanned ...
متن کاملVerification of inverse planning and treatment delivery for segmental IMRT
With intensity-modulated radiotherapy (IMRT), it is important that the inverse planning process yields the most appropriate dose distribution for the patient and that the delivered dose then corresponds to the planned dose. This paper presents methods by which the inverse planning and delivery of segmental (step-and-shoot) IMRT can be verified, and gives results for a typical treatment planning...
متن کاملIntraocular pressure elevation during radioactive plaque brachytherapy for uveal melanoma.
children (aged 6-16 years). An increase in IOP of 15 mm Hg or more was measured 11 patients (41%)—4 of 5 children and 7 of 22 adults. An increase of 20 mm Hg or more was seen in 2 of 5 children and 3 of 22 adults. The peak IOP was 30 mm Hg or higher in 3 of 5 children and 4 of 22 adults. All IOP increases responded to difluprednate discontinuation or addition of glaucoma medications. No patient...
متن کاملRadial dose functions of GZP6 intracavitary brachytherapy 60Co sources: treatment planning system versus Monte Carlo calculations
Background: The Monte Carlo (MC) method is not only used for dose calculations around brachytherapy sources but also for benchmarking treatment planning systems (TPS) calculations. Materials and Methods: Three 60Co sources of GZP6 brachytherapy unit were simulated using MCNP4C MC Code. The radial dose functions were calculated by MC method and GZP6 TPS and were compared. Results: There was a go...
