Diagnostic imaging plays a major role in Healthcare and the Imaging Physicists give support to diagnostic imaging departments throughout Manitoba. We work closely with the radiologist, physician and radiation technologist to ensure that the medical images obtained are the best that can be achieved.
The Physicist's expertise includes equipment specification and testing, quality assurance, optimization of techniques for clinical procedures, research and development and teaching.
Our professional standards are defined by the Canadian Organization of Medical Physics and the Canadian College of Physicists in Medicine.
The function of Imaging Physicists is to:
Imaging Physics promotes acceptable practice in medical imaging physics and maintains the level of professional standards defined by the Canadian Organization of Medical Physics and the Canadian College of Physicists in Medicine. Imaging recognizes the Canadian College of Physicists in Medicine as an accrediting body.
The key functions of Imaging Physicists include the following:
The imaging equipment that we are most familiar with includes the following:
A variety of different items are used as phantoms for testing diagnostic equipment.
Radioactive-labelled compounds are injected into a patient and their distributions recorded using a gamma-camera or PET camera. It provides excellent functional information but is slow.
Ultrasound uses high frequency (typically 2 to 13 MHz) sound to make images of soft tissues and measure blood flow. It is very safe, fast and relatively inexpensive.
CT uses x-rays to make cross sectional images. It is somewhat expensive and evolving rapidly.
Makes very-high resolution x-ray images of the breast. Currently most systems use film although digital instruments are available.
MRI uses a large static magnet along with time-varying magnetic fields to make images. It is very versatile and is particularly important in imaging the head and spine. Although very safe, it is also very expensive and somewhat slow.
An x-ray technique for making dynamic images (movies) of moving structures such as the heart. .
A filmless method for making x-ray images.
Consists of standard film-based and fluoroscopic x-ray systems. It also includes the film processors.
Includes the software and hardware required to store, retrieve, transmit, display and process medical images within a facility or between facilities. It is replacing film.
To assist diagnostic imaging sites with the development and implementation of equipment quality control (QC) programs for the various imaging modalities, the Imaging Physics Department has developed modality-specific quality control guidance documents. The documents provide a broad outline of the components of typical QC programs. They do not describe tests in detail. Actual QC programs may differ depending on the diagnostic imaging equipment age, patient load and available resources.
In addition, the following reference documents maybe useful for the establishment of the quality control programs.
The Imaging Physics Department at CancerCare Manitoba provides physics testing for diagnostic imaging equipment, and can assist diagnostic imaging departments in setting up QC programs, training staff to perform QC tests and identifying appropriate QC tools.
