A survey on radiation protection awareness at various hospitals in Karachi, Pakistan.

Purpose: To assess the awareness level of radiation protection among the radiation workers (i.e. medical radiation technologists, medical physicists, and medical radiological professionals) at the selected radiology, nuclear medicine, and radiotherapy facilities in Karachi, Pakistan.

Measurement of 6 MV small field beam profiles - comparison of micro ionization chamber and linear diode array with monte carlo code.

The objective of this study is to analyze small field photon beams acquired with commonly available detectors. Beam profiles of 6 MV photons from the Siemens Primus Linear Accelerator were measured with a micro ion chamber (IC CC01, IBA) and linear diode array (LDA-99SC, IBA). Data was acquired using a water phantom for small fields (0.

Recent Trend in Specialty Choices of Medical Students and House Officers from Public Sector Medical Universities, Karachi.

Objective: To determine career choices of medical students of public-sector medical universities and factors affecting their career choices.

Methods: The cross-sectional study was conducted at Dow University of Health Sciences and Jinnah Sindh Medical University, Karachi, from May 2015 to May 2016, and comprised 4th and 5th year medical students and house officers. A self-administrated structured questionnaire was used to collect data which was entered and analysed using SPSS 20.

A review of international and developed practices of medical physics from a legislative and regulatory point of view and its applicability and comparison with Pakistan.

The importance of the medical physics profession and medical physicists is widely recognized by the international bodies like ILO, IAEA, EC, etc. The description of a medical physicist's qualification framework, their role and responsibilities have been addressed in the legislative and regulatory frameworks of developed countries like the USA (in 10CFR) and the EC (EC RP 174) and less comprehensively in developing counties like Pakistan. AFOMP has contributed positively in various regulatory and policy matters regarding the medical physics practices in Asian countries.

Variations in the Dose Profiles of Physical and Virtual Wedge Filters of ONCOR Linear Accelerator.

Purpose: In this study, we measured the dose profiles of physical wedges (PWs) and virtual wedges (VW) for photon energies (6 MV and 15 MV), various field sizes (10 × 10, 15 × 15, and 20 × 20 cm), depths (d, 10 cm, 20 cm), and wedge angles (15°, 30°, 45°, and 60°). This study was performed using a Siemens ONCOR IMRT Plus linear accelerator. The acquired dose profiles of PW and VW were compared and statistically analyzed.

Vestibular schwannoma: an unusual post radiotherapy response.

Vestibular schwannoma is a relatively uncommon tumor. Although, it is benign but locally expansile and spreads to damage the adjacent structures. Treatment strategy includes surgery, Stereotactic Radiosurgery (SRS) either by standard or hypofractionated protocols.
