An small deep-placement fertilizer applicator (SDFA), to realize hill fertilization application and mark location with lime, was developed. It’s unique structure working principle were detailed. Orthogonal tests conducted by the software EDEM virtual simulation in order get parameters of applicator. The rotational torque much higher than resistant after optimization design. Field testing across...

Background and purposeTo investigate the accuracy of dwell position detection with a combined electromagnetic tracking (EMT) brachytherapy (BT) system for treatment verification, by quantifying positional errors due to EM field interference in typical pelvic BT clinical settings.Materials methodsDedicated prostate cervix phantoms were imaged CT. For phantom, Utrecht applicator + interstitial ca...

introduction pterygium is a wing-shaped, vascular, fleshy growth that originates from the conjunctiva and can spread into the corneal limbus and beyond. beta irradiation after bare sclera surgery of primary pterygium is a simple, effective, and safe treatment, which reduces the risk of local recurrence. materials and methods dosimetric components of strontium-90 (90sr), phosphorous-32 (32p), an...

The suitability of a natural diamond detector with a special contact system for the measurement of relative dose distributions in selected radiotherapy applications was studied. The performance of the diamond detector was analysed by comparison with measurements using an ionization chamber and a silicon diode detector. The good stability, high response and good spatial resolution of the diamond...

The histologic effects of a contact ultrasound applicator were compared with those of the immersion applicator that is currently used clinically for the treatment of glaucoma. The applicator coupling cone uses a distensible rubber membrane that can be inflated to control stand-off distance relative to the surface of the eye. This feature allows the focal point of the therapeutic beam to be plac...

Learning objectives Discuss the role and benefits of MRI in planning for brachytherapy treatment in cervical cancer. Discuss the key mechanisms of the applicator and the technical aspects of planning brachytherapy. Discuss the role of MRI imaging in recognising the features of appropriate applicator placement and common complications. Review key MRI features of radiation-related alterations in ...

Background: The dose rate distribution delivered by a low dose rate 137Cs pellet source, a spherical source used within the source trains of the Selectron gynecological brachytherapy system, was investigated using the MCNP4C Monte Carlo code. Materials and Methods: The calculations were performed in both water and Plexiglas and the absolute dose rate distribution for a single pellet s...

Dear Editor, I read with great interest the article authored by Dr. Leelavathi Basava et al. titled ‘‘Falope Ring or Modified Pomeroy’s Technique for Concurrent Tubal Sterilization ‘‘published in your (September–October 2016) 66 (S!): S198–S201. I would like to congratulate the authors for an excellent study in the search of a method for female sterilization technique, which is quicker and easi...
