Radiation dose to patient reduced by up to 80%

Traditional collimators on a gamma camera absorb a large amount of the counts produced by the patient. The Lowrad 10 allows the traditional collimators to be removed from the camera. This removes many of the lost counts associated with coincidence counting and collimator absorption.

The end result is that only 20% of the radioactive loading of a patient is required for Lowrad's Holographic Imaging System compared with PET or a gamma camera used with a conventional collimator. This also means a proportional reduction in the radiation dose to the radiographer.

The Lowrad 10 counts single photon emissions so there is no requirement for positron emitters. Conventional radioactive isotopes such as technetium-99, thallium-201 and iodine-123 can be used with significant financial savings over the more expensive isotopes required for PET for example.

Alternatively higher radiation doses can be given to a patient where a quicker image acquisition time is required. For example this could be valuable in paediatrics where the patients may not keep still for long periods of time.
