EM-enhanced US-based seed detection for prostate brachytherapy.

Intraoperative dosimetry in low-dose-rate (LDR) permanent prostate brachytherapy requires accurate localization of the implanted seeds with respect to the prostate anatomy. Transrectal Ultrasound (TRUS) imaging, which is the main imaging modality used during the procedure, is not sufficiently robust for accurate seed localization. We present a method for integration of electromagnetic (EM) track-ing into LDR prostate brachytherapy procedure by fusing it with TRUS imaging for seed localization.

Mental Nerve Blocks for Lip Brachytherapy: A Case Report.

Can reference images improve interobserver agreement in reporting liver fibrosis?

Staging of fibrosis in medical liver biopsies has inherent interobserver variability. There are a number of disease-specific scoring systems available. While recognising the importance of these scoring systems, there is scope to consider how concordance amongst histopathologists could be improved using a generic fibrosis staging system.Using virtual slides, we approached both specialist liver histopathologists and general histopathologists from the UK to assess the degree of fibrosis against a proposed four...

A Medicare cost analysis of MRI- versus CT-based high-dose-rate brachytherapy of the cervix: Can MRI-based planning be less costly?

While some institutions deliver multiple fractions per implant for MRI-based planning, it is common for only one fraction to be delivered per implant with CT-based cervical brachytherapy. The purpose of this study was to compare physician costs, hospital costs, and overall costs for cervical cancer patients treated with either CT-based or MRI-based high-dose-rate (HDR) cervical brachytherapy to determine if MRI-based brachytherapy as described can be financially feasible.

Validation of MRI to TRUS registration for high-dose-rate prostate brachytherapy.

The objective of this study was to develop and validate an open-source module for MRI to transrectal ultrasound (TRUS) registration to support tumor-targeted prostate brachytherapy.

Clinical outcomes with MRI-guided image-based brachytherapy in cervical cancer: An institutional experience.

To evaluate the long-term disease control and toxicity to the organs at risk after dose-escalated image-based adaptive brachytherapy (BT) in cervical cancer.

Dosimetric study of GZP6 Co high dose rate brachytherapy source.

The purpose of this study was to obtain dosimetric parameters of GZP6 Co brachytherapy source number 3. The Geant4 MC code has been used to obtain the dose rate distribution following the American Association of Physicists in Medicine (AAPM) TG-43U1 dosimetric formalism. In the simulation, the source was centered in a 50 cm radius water phantom. The cylindrical ring voxels were 0.1 mm thick for r ≤ 1 cm, 0.5 mm for 1 cm  5 cm. The kerma-dose approximation was performed for r > 0.75 cm to inc...

Medical cyber-physical systems: A survey.

Medical cyber-physical systems (MCPS) are healthcare critical integration of a network of medical devices. These systems are progressively used in hospitals to achieve a continuous high-quality healthcare. The MCPS design faces numerous challenges, including inoperability, security/privacy, and high assurance in the system software. In the current work, the infrastructure of the cyber-physical systems (CPS) are reviewed and discussed. This article enriched the researches of the networked Medical Device (MD)...

Principles and Practice of HDR Penile Brachytherapy: Planning and Delivery Techniques.

To allow for organ preservation, high dose rate brachytherapy may be used in the treatment of localized penile cancer. Penile cancer is a rare malignancy, accounting for less than one percent of cancers in men in the United States. The standard treatment for localized disease is partial amputation of the penis. However, patients with T1b or T2 disease, less than 4 cm in maximum dimension and confined to the glans penis may be treated with brachytherapy as an organ-sparing approach. Previous works have descr...

Why is brachytherapy still essential in 2017?

These recent years, brachytherapy has benefited from imaging modalities advances. A more systematic use of tomodensitometric, ultrasonographic and MRI images during brachytherapy procedures has allowed an improvement in target and organs at risk assessment as well as their relationship with the applicators. New concepts integrating tumor regression during treatment have been defined and have been clinically validated. New applicators have been developed and are commercially available. Optimization processes...

Surgical ward nurses' responses to worry: An observational descriptive study.

Rapid response systems aim to improve early recognition and treatment of deteriorating general ward patients. Sole reliance on deviating vital signs to escalate care in rapid response systems disregards nurses' judgments about a patient's condition based on worry and other indicators of deterioration. To make worry explicit, the Dutch-Early-Nurse-Worry-Indicator-Score was developed, summarising non-quantifiable signs of deterioration in the nine indicators: breathing, circulation, temperature, mentation, ag...

Microdosimetric Evaluation of Current and Alternative Brachytherapy Sources-A Geant4-DNA Simulation Study.

Radioisotopes such as (75)Se, (169)Yb, and (153)Gd have photon energy spectra and half-lives that make them excellent candidates as alternatives to (192)Ir for high-dose-rate brachytherapy. The aim of the present study was to evaluate the relative biological effectiveness (RBE) of current ((192)Ir, (125)I, (103)Pd) and alternative ((75)Se, (169)Yb, (153)Gd) brachytherapy radionuclides using Monte Carlo simulations of lineal energy distributions.
