Dosimetric evaluation in radiation synovectomy

Dosimetric Evaluation in Radiation Synovectomy

Rheumatoid arthritis can manifest itself through synovitis, of which the knee is the common locale. The treatment using an intra-articular radioisotope injection has been applied in various countries. In this work, the dose of radioactive material absorbed in the joint is evaluated, taking into consideration the dose received in the articular cartilage and adjacencies using a three-dimensional ...

Radiation synovectomy with yttrium--90 silicate.

Dosimetric evaluation of radiation dose rate effect in respiratory gated intensity modulated radiation therapy†

PURPOSE To investigate the dosimetric accuracy of the sliding window gated IMRT compared with the static treatment, using varying dose rates. MATERIALS AND METHODS This study measured changes in output and diode array response with changing dose rate, verified the precision of the motion table, and measured changes in dose distribution accuracy with film and diodes at two depths with changing...

A Dosimetric Evaluation of Organs at Risk in Prostate Radiation Therapy using a MAGIC Gel Dosimeter

Introduction: Multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. In this work, we investigated MR-based MAGIC gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. Materials and Methods: A heterogeneous slab phantom including bones was made....

Short-term evaluation of synovectomy in haemophilia.

Twenty-three operations of synovectomy (15 on the knee, 5 on the ankle, and 3 on the elbow) were carried out over a three-year period in 19 patients with severe haemophilia A and B who were followed for an average period of 15 months postoperatively. Short-term evaluation of the results was mainly based on the postoperative incidence of haemarthrosis and on the range of joint motion, which were...
