Contrast-to-noise ratio (CNR) that corresponds to the ratio of the differences between the mean pixel values of the signal and background, divided by the noise [ 31 ]. We estimated CNR using Equation (2) [ 32 ].

“…However, until adjustment to the new digital environment is accomplished, there is potential for increasing radiation dose mainly due to the perceived lack of visual control [2]. Currently image processing techniques and noise reduction algorithms add to the traditional optimization strategies for optimal radiographic imaging [46,47]. As already mentioned earlier monitoring of patient doses (in terms of exposure indices or relevant dose quantityies such as the Kerma-Area Product KAP) assists in optimization of all X-ray examinations and also radiographic procedures.…”

The medical radiological imaging technological evolution and wide availability has resulted in the exponential increase in utilization. Evidence for a risk of cancer arising from radiation doses of lower than 100 mSv is still limited. There is a need for patient dose optimization. A literature review was conducted to identify the reasons why optimization is important and the steps to be followed for a successful optimization process in digital radiology, Computed Tomography, interventional radiology and mammography.Based on recent literature, 5 steps for a dose optimization process are proposed. These steps are: 1) establishment of a quality assurance programme; a mistake, misuse or malfunction of an X-ray machine can potentially affect the health or life of thousands of people, 2) establishment of a dose optimization team consisting of a radiologist, medical physicist and radiation technologist, 3) determination of baseline dose levels and image quality as well as comparisons with benchmarks to decide which exam protocols should be optimized, 4) modification of protocols by the medical physicist and 5) evaluation of the optimization process and its effect on patient dose and image quality.The optimization process should include joint efforts focused on 1) equipment performance 2) exam protocol customization and 3) staff behaviour. Manufacturers should provide detailed descriptions of exam protocols and training on the use of dose reduction features. The diagnostic radiology medical physicist should emerge and take a proactive lead in the everyday clinical routine in order to promote the value of optimization process.

“…Recently, an image-processing technique called bone suppression (BS) processing has been developed and reported to be clinically useful [ [8] , [9] , [10] ]. BS attenuates the rib and clavicle signals in chest radiographs, and BS-processed images are similar to soft tissue images obtained using dual-energy subtraction [ 11 ].…”
