 The Linear 5ive MOSFET Array is ideal for LDR / HDR Brachytherapy and IMRT QA.
The Array contains five isotropic, energy independent MOSFET dosimeters, at 2cm intervals. The MOSFETs on the array can be read simultaneously, facilitating multiple dose measurements at several spatial points. The radio-opaque marker, located at the tip of the array, enables visualization under X-Ray imaging (CT, Fluoroscopy), allowing for five dosimetry points to be accurately located and easily compared to target doses.
Dynamic Dose Measurements for Brachytherapy Dosimetry
The Linear 5ive MOSFET Array™, when used in combination with the mobileMOSFET™, is the first and only commercially available combination that allows for real-time quality assurance of all brachytherapy procedures, without a significant investment in extra time.
Real-time dose profiling is provided by the in-vivo use of a mobileMOSFET Wireless Dosimetry System. the Linear Array is used for various HDR applications such as prostate and gynecological brachytherapy using Item 322-360.
When placed on the surface of the breast, the array can also validate Mammosite™ treatments. Implant and LDR dosimetry is performed using the higher sensitivity model, Item 322-362.
When inserted directly into a urethral catheter, the dose results provide immediate assessment of post-implant base and apex dose coverage, as well as the dose to organs at risk such as the urethra, rectum or bladder. This real-time dose feedback allows assessing the quality of the seed implant program in LDR and HDR brachytherapy. Absolute dose measurements or dose rate measurements are obtained in real-time. This helps to validate the quality of the treatment, and ultimately the quality of life for the patient.
