Dosimetric and radiobiological investigation of permanent implant prostate brachytherapy based on Monte Carlo calculations.

Purpose: Permanent implant prostate brachytherapy plays an important role in prostate cancer treatment, but dose evaluations typically follow the water-based TG-43 formalism, ignoring patient anatomy and interseed attenuation. The purpose of this study is to investigate advanced TG-186 model-based dose calculations via retrospective dosimetric and radiobiological analysis for a new patient cohort.

Methods And Materials: A cohort of 155 patients treated with permanent implant prostate brachytherapy from The Ottawa Hospital Cancer Centre is considered.

A novel optically transparent RF shielding for fully integrated PET/MRI systems.

Preclinical imaging benefits from simultaneous acquisition of high-resolution anatomical and molecular data. Additionally, PET/MRI systems can provide functional PET and functional MRI data. To optimize PET sensitivity, we propose a system design that fully integrates the MRI coil into the PET system.

[Self assesment grid for pre-examination phase].

This document is a proposal of questionnaire for self-assessment of pre-analytical phase referring to the different steps described in the document SG1-01. The questions are aimed at verifying that what is examined fulfills ISO 15189 standard requirements or in general tends towards client satisfaction. This questionnaire has been elaborated using 5 M risk assessment tool for exhaustiveness purpose.

[Guidelines for the pre-examination processing and transport of medical laboratory samples].

We resume here the guidelines about sample processing and transport for laboratory tests. All the steps of the pre-examination phase process, downstream to the recording of the requests, are described in this document. The purpose is to assure a secure and optimal sample management.

[Guidelines concerning sample reception and request recording of laboratory tests].

The process is described to help to achieve the requirements of the ISO 15189 standard. The precautions to be respected for a correct recording of the request are specified. The criteria for traceability are formalized.
