scan and full scan techniques for cone beam breast CT in terms of CT number, radiation dose distribution and CNR.Method and Materials:CT number comparison: A 11 cm diameter breast phantom, made of a stack of glandular and fat tissue, was analytically modeled to evaluate the difference of CT...
Full size image The concept of AOSH is explained as follows. We denote the position of rows that will be scanned with the sequence \(S = s{(j)_{0 \le j < r}} \), where j is the index of S, s(j) is the position of the jth scan row, and r is the total scan rows. The...

Two analytical methods were developed: a conventional full scan method for ions from 29 to 270m/z; and a SIM method using 16 time windows and different ions selected for the compounds in each window. Both methods used the same Tenax GR adsorbent sampling tubes, TD and GC parameters, and ...
Because the evidence regarding the efficacy of splinting short implants on strain distribution is limited, this study aimed to measure and compare the strains generated by splinted and nonsplinted screw-retained implant crowns for short implants with internal connections. Computed tomographic scan data ...
We tested the most popular duplicate file finders for Mac and prepared a comparison chart of them to help you make the right choice.
Response to chemotherapy was assessed after 2 or 3 cycles depending on centers and was based on clinical examination (endoscopic evaluation of larynx mobility) and imaging evaluation (CT scan and/or FDG PET/CT). The chosen primary endpoint is the lack of response to TPF, defined as a non-...
Biosynthesis of ent-kaurene was investigated in extracts of cell suspension cultures derived from tobacco callus (Nicotiana tabacum L.), tomato callus (Solanum lycopersicum L.), and in germinating tomato seeds. Incubation of extracts derived from the two cell cultures with either isopentenyl pyrophospha...
For a more precise comparison in the standardized sensitivity phantom, the intensity at 820 nm of the circled signal in the 2D transverse spectral scan was used in PAI. 3. Results 3.1. Phantom studies The results of the phantom study are depicted in Fig. 1 (resolution) and Fig. 2 (...
Full size image CT-guided Hook-wire lung nodule localization method The puncture was scheduled to be performed within 2 h prior to the procedure, and a chest CT scan was first conducted to determine the entry point, depth of entry, and angle of entry. The Hook wire was then punctured next...
