In addition, the proper computer software must be used to optimize these images. To accomplish this, however, requires the physician to become versed in the various techniques required to capture video and audio sequences from the ultrasound machine. With the advent of multimedia programs available for the laptop and desktop computer, it is now possible to display real-time motion sequences that duplicate the actual scanning environment. video tape recordings of the examination. Unfortunately, the presentation of real-time images has not been incorporated into most presentations because of the difficulty of preparing and editing. Although ultrasound originally employed only still images, the development of real-time ultrasound ushered in a new imaging modality. In the end, the present study provides some notes and discussion about the applications of the newly created deconvolution spreadsheets.įor a number of years the teaching of ultrasound principles has relied on slides of static, nonreal-time images. In order to run some tests using these spreadsheets, four different sets of experimental data originated from different sources were used each time, with the calculated values being compared to the literature. After that aim is achieved, five spreadsheets were created, namely the TL deconvolution, the CW-OSL deconvolution, the LM-OSL deconvolution, the OTOR model Dose response and the TTOR Dose response. The first step is the creation of a computational code of the Lambert W function in VBA at Excel. The main aim of the study is to recreate these five expressions in different Excel spreadsheets, for a more practical use. Recently, researchers created some new analytical equations for the TL, CW-OSL and the LM-OSL phenomena, based on the Lambert W function, with the use of a single master equation, as well as some new dose response curves based on a) the simple One Trap One Recombination (OTOR) model and b) the more complex Two Traps One Recombination (TTOR) model. Nowadays, there are plethora of deconvolution methods with none of them being dominant and universal.

In order for the information of a glow or decay curve to be used correctly, the deconvolution of the said curve is essential. The Thermoluminescence (TL) and the optically stimulated luminescence (CW-OSL, LM-OSL) are widely used by the scientific community in different applications.
