من أجل حساب توزع الجرعة الإشعاعية للحزمة الفوتونية ذات الطاقة 6 MeV , عند أعماق مختلفة داخل فانتوم مائي ثلاثي الأبعاد، اِستُخدم الكود MCNP4C2, و قورنت النتائج مع نظام تخطيط العلاج الحاسوبي (TPS) , وتبين أن هناك توافقاً جيداً في حساب توزع الجرعة المحسوبة بواسطة الكود MCNP4C2 و نظام تخطيط العلاج الحاسوبي (TPS). كما تبين أن الكود MCNP4C2 يعطي دقة جيدة عند حساب توزع الجرعة الإشعاعية لحزمة الفوتونات ذات الطاقة 6 MeV , لذا فإن الحساب بهذا الكود هو طريقة موثوق بها لحساب الجرعة الإشعاعية التي يتلقاها المرضى.
To calculate the dose distributions of 6 MeV photon beam at variable depth in 3D water phantom the MCNP4C2 code was used, and the simulated dose profile was compared with that of the treatment planning computer system (TPS), and a good agreement was found between them. In conclusion, the MCNP4C2 code package presents a good tool adaptable to get dose distributions for the 6MeV photon beam and it can be considered as confirmed method for patient dose calculations.

The MCNP4C2 Monte Carlo code was used to model the Egyptian Second
research reactor in this paper, to calculate the effective multiplication factor
keff, distribution of the thermal and fast neutron fluxes and power in reactor
core with two type o
f fuels: standard and mixed. The values of the keff were
1.21842 and 1.05272, the maximum thermal flux were 2.975x10+14 and
3.352x10+14 n/cm2s, and the maximum fast flux was 2.950x10+14 and 2.389x10+14
n/cm2s for standard and mixed fuels respectively. The results showed good
agreements with previous results available in the literature.
Fetus images produced by 2D ultrasound devices are ambiguous and lack precision. This led to the need
for offering a 3D visualization of the fetus, which allows visualizing width, height, and angle, in order to
get additional information about the
fetus, and detect fetus abnormalities.
We explain in this paper our method in producing 3D models of the fetus from 2D images using a
computer system without the need for changing the 2D imaging devices, and without using position
sensors.
Our method is based on passing the probe over the pregnant woman's abdomen and make a manual scan
for the entire body of the fetus from top of the head till the bottom of his feet, then it saves this scan as a
video clip then send, it to the computer which segments the video into multiple images which are saved and
later processed using digital processing principles of images. Then these processed images are
reconstructed to produce the volume matrix and then display it in a 3D form using 3D model construction
methods.
We applied our software on various fetuses of different ages and got volume images which are considered
good in comparison with the images offered by currently available systems and devices. The precision of
the images we got, differs according to the change in fetus pose, amniotic liquid, and fetus size, The
obstetrician or gynecologist can retrieve more precise details by changing the angle and displaying volume
images of certain part of the fetus body.
This paper introduces, a proposed new identification method based on 3D
Ridglet Transform. First phase, it considers the three dimensional fingerprint
of human as a Personal Identification Number. Next, it produces the
required features using the
new proposed 3D Ridglet Transform. This
transform is a generalization of adapted 2D Ridglet form.
In the second phase we will consider the Back Propagation Neural Network
authentication process, the evaluation tests of the proposed algorithm on a
given database, for fifteen human Finger-Print, produce a perfect
identification results (in comparison with [12]).
Based on the evaluation test, we obtain that the authentication of the
allowed Human Finger-Print on a noisy data, with a noise level up to 69%
also with rotation of the input human Finger-Print up to 9 degree of
rotation.
The MCNP5-beta code was used to calculate the reaction rate and the neutron energy response matrix of a neutron spectrometry consisting of a Polyethylene sphere with variable diameter and BF3 detector, using point and disk neutron sources, the reacti
on rate and the response matrix of disk neutron source shows higher values than those obtained for point neutron source in addition the response with disk neutron source at the energy range shows a maximum value for sphere of 10 inch diameter where the response with point neutron source stile increasing in this condition .The results obtained in this work for the disk neutron source agreed well with published results.
Using the Mont Carlo code (MCNP4C2), doses were calculated for organs of
interest such as intestine, urinary bladder, rectum, vagina uterus, pancreas,
spleen, liver, spinal cord and kidneys while patient was undergoing cervix
brachytherapy by LDR
instrument (Cs-137).
