パソコンのスペック

3Dイメージングを始めるとき、パソコンのスペックが気になります。研究に使用しているパソコン環境を紹介します。

Hardware

Computers, used for Sci Rep 7:3645, 2017

iMac 2012 Late, 27 inch, 3.4 GHz Core i7, 32GB 1600 MHz DDR3, nVIDIA GeForce GTX 680MX 2 GB, 3 TB HDD

MacBookPro Early 2015, 13 inch, 3.1 GHz Corei7, 16GB 1867 MHz DDR3, Intel Iris Graphics 6100 1.5GB, 512 GB SSD

Computers, current

iMac 2015, 27 inch, 4.0 GHz Core i7, 32GB 1867 MHz DDR3, AMD Radeon R9 M395X 4 GB, 3 TB HDD

iMac 2017, 27 inch, 4.2 GHz Core i7, 64GB 2400 MHz DDR4, AMD Radeon Pro 580 8 GB, 1TB SSD

Recommended memory size is 16GB or more. Newer GPU is better, but VRAM 2GB was enough to produce our paper.

 

Software

RAW-JPEG conversion

Adobe Bridge CS6, CC

We routinely convert 500-1500 images at once. Adobe Lightroom and Nikon Capture NX-D also work well, but occasionally fail to convert.

Image Adjustment

Adobe Photoshop CS6, CC

We prefer to use Photoshop just because it is multi-lingual. ImageJ (freeware, English) also works well.

Image Registration

ImageJ v1.47, plug-in “Image Stabilizer

StackReg, a pre-installed plug-in, also works well, but it occasionally failed registration, which could not be corrected after registration. ImageJ v2.0 could not execute multi-tasks (2016). I couldn’t check E-mail or browsing internet, while running ImageJ v2.0 for image registration on iMac 2012. Fiji-ImageJ is convenient as it contains many plug-ins for 3D imaging, but it is provided as v2.0 (2016.12).

3D reconstruction

OsiriX 6.5 (commercial-ware from Pixmeo SARL). OsiriX MD (v8.5.2) is the latest version in June 2017. OsiriX is capable of MPR using RGB color images.

“Horos” (freeware) and “OsiriX 5.9” (commercial-ware from Newton Graphics Inc, Sapporo, Japan) were developed basing on OsiriX 5.9, open-source version. “3D slicer” (freeware) also can be used. Note that these are capable of MPR from grayscale images, not from RGB color images.

For Windows, “SSC DICOM Viewer” (freeware, 32 bit, Sainen Systems, Ishikawa, Japan) and  “CTVox” (freeware, 32 bit, 64 bit, Burker, Kontich, Belgium) may be used.
