CT Beam Width Measurements Made Easy

CT Beam Width MeasurementsRadcal is a premier provider of diagnostic radiation test instruments including the most comprehensive suite of x-ray sensors in the industry.  Among these are an extensive selection of gold standard ion chambers including those tailored for CT quality assurance and maintenance.  ACR and Joint Commission requirements demand that medical physicists measure beam width for today’s CT systems.  Methods for performing this measurement either require special hardware and software or expensive consumables.  Radcal is pleased to introduce The CTBW Tool Kit based on patent pending technology.  This economical Toolkit works in conjunction with Radcal’s 10×6-3CT ion chamber to make beam width measurements with excellent precision.  Two exposures determine a calibration factor and then beam widths for each additional collimation setting are calculated from a single additional exposure.  Radcal’s free Accu-Gold Excel software automates the process and makes these measurements quick and easy.

Accu-Dyn+ Digitizes Dynalyzer Results and Makes Them Available in Microsoft Excel

Accu Dyn+X-ray generators are manufactured to exacting standards that require precise measurement of the voltage (kV) and current (mA) applied to the x-ray tube. Radcal’s Dynalyzer product is the gold standard for measuring these quantities in the production environment. In the past, visualizing the data provided by the Dynalyzer required a digital display or scope. Radcal is pleased to announce the release of the Accu-Dyn+ solution which digitizes Dynalyzer results and makes them available in Microsoft Excel on a Windows-based tablet or personal computer. Analysis and reporting of kV behavior and practical peak voltage (PPV) has never been easier.

Monday November 7th is International Day of Medical Physics

international-day-of-medical-physicsTo raise awareness of our profession, the International Organization for Medical Physics (IOMP) will celebrate this year, on November 7, the International Day of Medical Physics (IDMP).

On that day in 1867, Marie Sklodowska-Curie, known for her pioneering research on radioactivity, was born in Poland. The theme of IDMP 2013 is ‘Radiation Exposure from Medical Procedures: Ask the Medical Physicist!’ This is an excellent opportunity to promote the role of medical physicists in the worldwide medical scene.

Beam Alignment Phantom

A routine test object designed to be used quickly and easily on a regular basis (e.g. weekly/monthly) to provide an ongoing check of beam alignment and centring.

Used for Radiography or Fluoroscopy, enables the following checks to be made:

  • The correspondence of the light field with the effective radiation field.
  • The determination of the position of the central beam.
  • The central beam angle deviation from 90°, relative to the plane of the film/detector, is below a limit that beyond which the image quality would be adversely affected.

The TOR ABC is available on its own or with either the hanger vertical bucky jig or the suction vertical bucky jig.

*** A special variant of the vertical bucky jig is available for Siemens’ Vertix system. Please request at time of order ***
