“…Dosemap is a software package developed by GE Healthcare to provide a live analytic estimation of PSD during procedure. 6 The outer shape of the patient is based on two super-ellipses model, built from real CT scan and defined by an equation previously described. 10,11 The local dose on this virtual envelope is then calculated as the following:…”

“…However, the use of these films in daily practice remains expensive and not easy to use. In this way, Dosemap software has been developed to estimate the PSD received by the patient in real time during the procedure . This system estimate the local dose distributed on the skin of the patient using dosimetric and technical information collected throughout the procedure.…”

“…This system estimate the local dose distributed on the skin of the patient using dosimetric and technical information collected throughout the procedure. The Dose‐Map™ (Ashland Inc., Ashland, KY, USA) method has been shown to be an interesting tool as compared to gafchromic film with an accuracy of 14.3% in case report and 24.9% in experimental model, but its use is not validated in real clinical practice. However, specific sub‐population of patient at high risk of radiation exposure could benefit from this real time monitoring, like obese patient.…”

Objectives The aim of this study was to determine the accuracy of DoseMap™ software as compared to gafchromic film in real clinical practices. Background The radiation exposure from cardiovascular procedures could expose patients to potential risk of cancer and/or skin injury. New tools like Dosemap software were developed to estimate the patient skin dose in the cardiac catheterization laboratory. However, little data are available to validate this estimation of patient radiation skin dose. Methods This is a prospective cross‐sectional study comparing the peak skin dose (PSD) measured by gafchromic film used as reference with an estimated PSD given by Dosemap software, in patients with BMI > 30 kg/m2 undergoing elective diagnostic and/or therapeutic interventional cardiology procedures, from April 2016 to December 2016, at the Brest University Hospital Centre, France. Results After four exclusions of patients for poor quality of gafchromic films, 90 patients were included, with 58 angiography (67.4%), 14 percutaneous interventions (16.3%), and 14 both (16.3%). The median PSDDosemap and PSDFilm were similar with 157 mGy [IQR: 99; 273] versus 158 mGy [IQR: 101; 295] (P = 0.65), respectively, with an excellent correlation (r = 0.95). The comparison between cumulative air kerma and PSDFilm was different 366 mGy [IQR: 246; 575] versus 158 mGy [IQR: 101; 295] (P < 0.01) with moderate correlation (r = 0.79). No correlation was found between the dose area product and PSDFilm (r = 0.51). Conclusion DoseMap is an effective and valid method as compared to gafchromic films to estimate PSDs during interventional cardiologic procedures.

“…PSD can also be calculated from indirect dose metrics, such as the KA ref or the P KA 8-10 . On-line tools have been developed to monitor PSD and give a skin dose map 90 for radiation risk management during interventions 11,12 . Direct measurements of PSD can be performed using Gafchromic® films XR-RV3 5, 6, 12-16 .…”

In this study, the impact of radiochromic films' (XR-RV3) calibration on PSD measurements was investigated under various peak kilovoltage (kVp) and additional filtration conditions. Films were calibrated free-in-air for six beam qualities with Allura Xper FD20 system (Philips). Six calibration curves (CCs) were constructed. Each beam quality was characterized in terms of mean energy (ME) in the air, with table, with table and water phantom using Monte Carlo simulations. A cohort of 155 patient films from cardiology (37) and vascular (118) procedures were read with each CC. Routine calibration beam quality was taken as reference (DoseNorm). Overall, it was observed that for a wider ME difference between the exposed film and the CC used, a larger deviation (from -28% to +41%) was observed. The choice of beam quality for the calibration is a key point when additional filtration and kVp are automatically controlled in clinical conditions.

“…CareMonitor by Siemens and DoseWise by Philips are solutions which basically provide the accumulated peak air kerma in the current projection 3 . On the other hand, Dose Map from GE is an advanced two‐dimensional (2D) solution, 4–6 while Dose Tracking System (DTS) from Canon (Toshiba) represents a state of the art three‐dimensional (3D) solution for skin dose mapping 7–9 . The most important drawback of previously mentioned solutions is that they are vendor specific and cannot be used in fluoroscopy systems from other manufacturers.…”

Purpose The purpose of this paper is to present and validate an originally developed application SkinCare used for skin dose mapping in interventional procedures, which are associated with relatively high radiation doses to the patient’s skin and possible skin reactions. Methods SkinCare is an application tool for generating skin dose maps following interventional radiology and cardiology procedures using the realistic 3D patient models. Skin dose is calculated using data from Digital Imaging and Communications in Medicine (DICOM) Radiation Dose Structured Reports (RDSRs). SkinCare validation was performed by using the data from the Siemens Artis Zee Biplane fluoroscopy system and conducting “Acceptance and quality control protocols for skin dose calculating software solutions in interventional cardiology” developed and tested in the frame of the VERIDIC project. XR‐RV3 Gafchromic films were used as dosimeters to compare peak skin doses (PSDs) and dose maps obtained through measurements and calculations. DICOM RDSRs from four fluoroscopy systems of different vendors (Canon, GE, Philips, and Siemens) were used for the development of the SkinCare and for the comparison of skin dose maps generated using SkinCare to skin dose maps generated by different commercial software tools (Dose Tracking System (DTS) from Canon, RadimetricsTM from Bayer and RDM from MEDSQUARE). The same RDSRs generated during a cardiology clinical procedure (percutaneous coronary intervention—PCI) were used for comparison. Results Validation performed using VERIDIC's protocols for skin dose calculation software showed that PSD calculated by SkinCare is within 17% and 16% accuracy compared to measurements using XR‐RV3 Gafchromic films for fundamental irradiation setups and simplified clinical procedures, respectively. Good visual agreement between dose maps generated by SkinCare and DTS, RadimetricsTM and RDM was obtained. Conclusions SkinCare is proved to be very convenient solution that can be used for monitoring delivered dose following interventional procedures.
