Abstract A basic diagnostic imaging quality assurance program is a regulatory requirement in many provinces Footnote 1Footnote 2 Footnote 3 Footnote 4 Footnote 5 and in federal institutions.

Footnote 10 An ineffective quality assurance program can lead to poor quality radiograms that can impair diagnosis, increase operating costs and contribute to unnecessary radiation exposure to both patients and staff. Any extension of the basic quality assurance program is the responsibility of each x-ray facility.

To achieve maximum benefit, all levels of management and technical staff must support and participate in the operation of a well-defined program.

This article outlines the essential aspects of a quality assurance program and is intended to encourage the review of a moderate size hospital's x-ray imaging quality assurance procedures. Formerly he was with the National Dosimetry Services of Health Canada where he worked on thermoluminescent extremity dosimeters.

Prior to that he worked at the Department of National Defense in the research and development of radiation detection instruments. Acknowledgements The authors wish to thank Mr. Waight of the Radiation Protection Bureau for their review comments and recommendations.

Discussions with and comments by the authors' colleagues are also gratefully appreciated. Introduction Each year, more than 20 million diagnostic x-ray procedures are performed in Canada.

Three-Dimensional Conformal Radiation Therapy (3D-CRT)

Although the radiation exposure connected with these procedures cannot be avoided, there are means to reduce it as much as possible.

For the protection of patients, workers and the public for example, federal and provincial government agencies enact legislation and take necessary steps to ensure that only safe and properly installed x-ray equipment is used in Canadian diagnostic x-ray facilities, for the protection of patients, workers and the public.

Also, in most provinces Footnote 1 Footnote 2 Footnote 3 Footnote 4 Footnote 5 and in federal institutions Footnote 10 there is a requirement that each diagnostic x-ray facility have in place a basic quality assurance QA program to control the quality of diagnostic images.

Any extension of the basic program is determined by the radiology department's management and QA committee. A successful QA program requires that all staff within the radiology department understand the goals set out in the program and take an active part in achieving its objectives.

Any program lacking genuine interest from its staff and initiated only to satisfy a regulatory requirement is unlikely to produce optimal results. Meticulous care is required in the quality control of diagnostic imaging equipment to ensure good quality radiograms.

How does radiotherapy work?

This article is divided into two parts. Part I discusses the essential aspects of a QA program recommended for implementation in a moderate-sized hospital's x-ray facilities. Part II contains detailed worksheets designed to help radiology personnel charged with reviewing their current diagnostic x-ray imaging QA procedures.

Definition It is necessary to define, at least briefly for the purposes of this article, the general concepts of quality assurance and quality control and to review the principal objective of a radiology quality assurance program.

Quality assurance QA is a program used by management to maintain optimal diagnostic image quality with minimum hazard and distress to patients. The program includes periodic quality control tests, preventive maintenance procedures, administrative methods and training.Sensus Healthcare is focused on making proven non-melanoma skin cancer solutions more accessible to patients.

Their dedicated superficial radiation therapy (SRT) systems are designed specifically to provide an alternative to surgical procedures for basal cell and squamous cell carcinomas. Daily quality assurance procedures are an essential part of radiotherapy medical physics. Devices such as the Sun Nuclear, DQA3 are effective tools for analysis of daily dosimetry including flatness, symmetry, energy, field size and central axis radiation dose measurement.

The DQA3 can be used on the treatment couch of the linear accelerator or on a dedicated table/bed for superficial and. Precise naming and definitions of energy ranges may vary, and X-rays at the lower end of this range may also be known as Grenz rays.

They are useful in radiation therapy for the treatment of various benign or malignant skin problems, including skin cancer and severe kaja-net.com "We are privileged to work with the global leader in X-ray therapy devices," said Larry Findleton, president at AlderMed.

"We believe our service improves the quality of care for the patient. • Quality assurance Outline McGill Practical Medical Physic s -AAPM 3 Low energy photon radiotherapy • Less complexity of machine and treatment • Easy setup – Disadvantages • Penetrating beam – Comet MXR metal Ceramic x -ray tube assembly – 9 treatment filters and 1 warm up filter – 6 square applicators (SSD = The treatment options are diverse, including plastic surgical excision, Moh’s microsurgery, electrocautery, topical 5-fluorouracil and imiquimod, photodynamic therapy and superficial radiotherapy.

Advances in surgical techniques have meant that the population of patients treated with radiotherapy has changed.
