Cancer imaging - making the most of your gamma camera

Cancer imaging—making the most of your gamma camera

As MRI threatens the use of bone scintigraphy for skeletal metastases and 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET) emerges as the main focus in nuclear oncology, the future role of the gamma camera in cancer imaging appears unclear. However, there is a range of pre-existing conventional gamma camera techniques that have incremental benefit over CT and other structural ima...

Getting the Most from Your IR Camera

Radiometry is the measurement of radiant electromagnetic energy, especially that associated with the IR spectrum. It can be more simply defined as an absolute measurement of radiant flux. The typical unit of measure for imaging radiometry is radiance, which is expressed in units of Watts/(sr-cm2). (The abbreviation “sr” stands for steradian; a non-dimensional geometric ratio expressing the soli...

Making the most of your search model

In cases with high sequence homology, Molecular Replacement (MR) is usually a trivial exercise. But, as the structural homology gets lower and lower, solving the structure by means of MR becomes increasingly difficult. Conventional wisdom holds that an RMSD of about 1.5Å between the search model and the actual structure constitutes the limit at which MR can still be used. Fortunately, the MR pr...
