REVIEW
Takuya Furuta, Tatsuhiko Sato
Time-consuming Monte Carlo dose calculation becomes feasible owing to the development of computer technology. However, the recent development is due to emergence of the multi-core high performance computers. Therefore, parallel computing becomes a key to achieve good performance of software programs. A Monte Carlo simulation code PHITS contains two parallel computing functions, the distributed-memory parallelization using protocols of message passing interface (MPI) and the shared-memory parallelization using open multi-processing (OpenMP) directives...

The recent improvements in magnetic resonance (MR) hardware, especially 3T devices, scanning protocols, and three dimensional (3D) volumetric reconstruction software have facilitated great expansion of the role of 3D imaging. With the volumetric data, various post processing image reconstructions could readily be done on the 3D workstation. The reconstructions allow better demonstration of anatomic details, which help improve lesion localization and surgical planning. Particularly, in patients who are planned for surgery such as tumors assessment or pre-transplant evaluation, the 3D reconstructions provide not only better tumors extent, tumors volume evaluation and an excellent anatomical guide map, but also tumors relations with the blood vessels...

Yasushi Tagaya
Recently, MSCT acquisition of volume data becomes easier. For computer processing technology has advanced, was the performance of the workstation also be improved. Therefore, three-dimensional representation of the whole body is also made possible. Three-dimensional display, is usually doing the diagnosis in only axial image, it is useful to understand the structure that traveling to the cranio-caudal direction. When surgical care is necessary, an examination for CT is conducted for the purpose of a metastasis search...

The three-dimensional representation is used by cerebral blood flow SPECT and myocardial SPECT. It is used with the statistical image analysis software (3D-SSP, eZIS) in cerebral blood flow SPECT, and regional cerebral blood flow decrease can be detected. It is used with the heart function analysis software (QGS, QPS, QBS) in myocardial SPECT, and is effective for the cardiac wall motion evaluation. SPECT/CT and PET/CT are used in clinical. The three-dimensional fusion image that overlaps CT- volume rendering image with SPECT (PET) image can be constructed with an easy and high quality by SPECT/CT (PET/CT)...

It has been than 15 years since medical image analysis is used clinical scene. We provide 3D image for doctors to recognize easily by reconstructed CT or MRI images. It is introduced a recently technique for 3D medical image, for example, volume rendering, CPR, colon analysis, CT-SPECT fusion image.

Imaging techniques to obtain a tomographic image in nuclear medicine such as PET and SPECT are widely used. It is necessary to interpreting all of the tomographic images obtained in order to accurately evaluate the individual lesion, whereas three dimensional display is often useful in order to overview and evaluate the feature of the entire lesion or disease such as the position, size and abnormal pattern. In Japan, the use of three dimensional image analysis workstation with an application of the co-registration and image fusion between the functional images such as PET or SPECT and anatomical images such as CT or MRI has been generalized...

REVIEW
Kazuma Nakazeko
Medical images are being recently reconstructed using several data sets. In x-ray and computed tomography (CT), 3-dimensional (3D) images are reconstructed using 2-dimensional (2D) projection data. Research regarding the image reconstruction method has been actively conducted. Further, 3D images include patient information and are used as diagnostic tools. Therefore, it is necessary to acquire a projection technique. There are several algorithms of the projection method. In this paper, we reviewed three methods...

Medical imaging is one of the major tools that have enriched medical science, disease detection and treatment. Computed tomography (CT) is the most widely used imaging modality in clinical practice for cancer detection, oncologic diagnosis, and treatment guidance. Recent advances in CT imaging technologies allow the high-throughput extraction of informative imaging features to quantify the differences that oncologic tissues exhibit. The development of computer-aided detection/diagnosis (CADe/CADx) systems based on imaging biomakers associated with disease probabilities may become increasingly an attractive field to support clinicians in detecting early-stage diseases and determining risk-adaptive treatments...

We developed a text-data based learning tool that integrates image processing and displaying by Excel. Knowledge required for programing this tool is limited to using absolute, relative, and composite cell references and learning approximately 20 mathematical functions available in Excel. The new tool is capable of resolution translation, geometric transformation, spatial-filter processing, Radon transform, Fourier transform, convolutions, correlations, deconvolutions, wavelet transform, mutual information, and simulation of proton density-, T1-, and T2-weighted MR images...

PHITS is a general purpose Monte Carlo particle transport simulation code developed through the collaboration of several institutes mainly in Japan. It can analyze the motion of nearly all radiations over wide energy ranges in 3-dimensional matters. It has been used for various applications including medical physics. This paper reviews the recent improvements of the code, together with the biological dose estimation method developed on the basis of the microdosimetric function implemented in PHITS.

In Hitachi Medical Area, a large-scale lung cancer screening program using low-dose CT has been underway in two medical facilities since its introduction in 1998 and 2001. A total of 61,914 tests were performed among 25,385 participants until 2006. Two hundred and ten lung cancer patients had been identified on CT screening. The estimated 5-year survival rate for all patients was 90%. Among residents in Hitachi City, nearly 40% of inhabitants aged 50-69 years were estimated to have participated in the screening from 1998 through 2009...
