The Monte Carlo method was applied using the PENELOPE code to simulate the transport of particles in two different x-ray tubes. This method is considered the most important and accurate for simulations and calculations in different branches of science, including medical physics. The tubes were modeled according to the manufacturer’s specifications, and the simulations were divided into two stages due to the computational time. The scope of the work was to obtain in greater detail photon spectra of different qualities of beams in the orthovoltage range used in radiotherapy, since few works have, yet been developed for this energy range. A detailed analysis was carried out by comparing to the spectra results obtained using the SpekCalc software for the different qualities of radiation in the two stages. Mean energy values along with the first and second half-value layers (HVLs) of each energy were determined with the respective differences between them. Different discrepancies were found in most cases, and so it is vitally important to consider each situation independently. Finally, secondary electron energy spectra in the second stage of each quality were presented with their respective mean energies, an important parameter considered in the dose deposition of the different experimental geometries that use such qualities.
使用 PENELOPE 代码应用蒙特卡罗方法模拟粒子在两个不同 X 射线管中的传输。这种方法被认为是包括医学物理学在内的不同科学分支中最重要、最精确的模拟和计算方法。X射线管是根据制造商的规格建模的，由于计算时间的原因，模拟分为两个阶段。这项工作的范围是更详细地获取放射治疗中使用的正电压范围内不同质量光束的光子光谱，因为针对这一能量范围的工作还很少。通过比较使用 SpekCalc 软件获得的光谱结果，对两个阶段的不同辐射质量进行了详细分析。确定了平均能量值以及每种能量的第一和第二个半值层（HVL）以及它们之间的差异。在大多数情况下都发现了不同的差异，因此独立考虑每种情况是非常重要的。最后，每种质量第二阶段的二次电子能谱都有各自的平均能量，这是在使用这些质量的不同实验几何图形进行剂量沉积时需要考虑的一个重要参数。

Introduction: Headache is one of the most common complaints in patients pushing them for medical attention in the depart of emergency medicine and neurology clinic. Computed Tomography (CT) scan has a low yield value in patients with primary headaches without any neurological deficit. No national or international guidelines have been established yet for the clinical indication of neuroimaging. The main aim of our study is to determine the role of CT imaging in diagnosing a patient presented with a headache and evaluate the context of CT prescription in developing countries versus developed countries. Methodology: This study was a multicentric Retrospective study carried out from the data collected from Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) from 2017-2019 AD. A total of 2184 patients were included in the study who were requested for CT scans by their primary care physician. Collected data was entered and analyzed through the SPSS version 21 and Microsoft Excel 2021. Result: The total number of patients was 2184 with a predominance of females (63.02%) against males (36.98%) with a ratio of 1.7:1. CT scan findings were normal in 2060 cases which comprise 94.3 %, and positive in 124 cases accounting 5.7 % of the total study. The maximum number of cases was found in the age group between 21-30 years with 772 cases (35.3%) followed by the age group 31-40 years with 474 cases (21.7%), age group 11-20 years with 368 cases (16.8%), age group 41-50 years with 321 cases (14.67%), Age group 51-60 years with 131 cases (5.97%), age group 0-10 years with 83 cases (3.80%) and the least number of cases of 35 (1.67%) at the age group between 61-70 years. Conclusion: Computed Tomography y has a low yield value in the diagnostic evaluation of patients with headaches who had no focal neurological signs. Its overuse can cause a socio-economic burden on the patients including radiation hazards. Thus, it is not justifiable for patients with low to middle-income resource countries.

Purpose of the study: Explore the role of MRI in the diagnosis of Charcot foot in patients with active diabetic osteoarthropathy. Material and methods research: 35 patients (prospectively) with type 2 diabetes mellitus and Charcot foot in the active phase were examined in the period 2022-2023 at the Acad. Y.H. Turakulova, in the department reconstructive plastic surgery of complications of diabetes mellitus. The control group consisted of 20 people with type 2 diabetes mellitus without Charcot foot in compensation. Of the 35 patients, there were 28 men and 7 women. Average age: men was 64.12 ± 5.8 years, women - 62.15 ± 4.6 years. The duration of type 2 diabetes mellitus ranged from 17 to 20 years. Research methods included: biochemical, hormonal and instrumental: ECG, MRI of the feet, ultrasound of the internal organs, DECA of the body, fundus. Research results: All patients were in a state of carbohydrate metabolism decompensation. In addition, pathological changes in bone tissue increased as the average values of glycated hemoglobin increased. As the level of carbohydrate metabolism decompensation increased, the degree of bone tissue recovery decreased (inverse correlation). Conclusions: 1. An early symptom on MRI with Charcot foot was the presence ofconcavity of the articular surface of the talus against the background of sclerosis in the talonavicular joint. 2. Pathological changes in the bone tissue increased as the average values of the level of glycated hemoglobin increased. 3. A direct correlation was found between the MRI parameters in Charcot foot and the HbA1c level: as the level of carbohydrate metabolism decompensation increased, the degree of bone tissue recovery decreased.

Introduction: To investigate the impact of nasal packing on radiotherapy dosimetry for nasal and paranasal sinus cancers treated with intensity modulate radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) technique. Methods: A prospective database identified all patients with primary nasal and paranasal sinus cancers treated with adjuvant radiotherapy. All patients were simulated using CT scanning with packing in the nasal cavity. For this study the nasal packing was contoured and assigned an electron density equivalent to air. The dose to the pre-operative gross tumour volume (GTV), planned tumour volume (PTV) and organs-at-risk (OAR) were re-calculated and compared to those with nasal packing, using both the Pinnacle (Collapsing Cone Convolution) and Monaco (Monte Carlo) planning systems. Results: 24 patients were identified, predominantly ethmoid (14) or maxillary (4) primaries. The predominant histology was SCC (12/24). The majority (22/24) were treated with curative intent. Using Collapsing Cone Convolution calculation, the median [range] coverage of 95% of prescribed dose to high-dose PTV (95.5% [92.2-98.5%] vs 95.2% [92.1-98.5%]; packing vs no packing, P=1.00) and low-dose PTV (95.8% [90.0-99.4%] vs 95.9% [91.1-99.7%]; packing vs no packing, P=1.00) were not impacted by packing the nasal cavity. There was also no impact by no packing on the maximal dose to the brainstem, optic nerves, optic chiasm nor lens. Conclusions: Packing of nasal cavity does not change the dose to the PTVs or critical OARs in patients with nasal and paranasal sinus cancers treated with adjuvant IMRT or VMAT radiotherapy and can be safely omitted.
前言:探讨鼻腔填充物对强度调节放疗(IMRT)或体积调节弧线治疗(VMAT)鼻窦癌放疗剂量测定的影响。方法:前瞻性数据库确定所有接受辅助放疗的原发性鼻窦和副鼻窦癌患者。所有患者均采用鼻腔填塞CT扫描模拟。在这项研究中，鼻填充物被勾画成轮廓，并被赋予相当于空气的电子密度。使用Pinnacle(塌锥卷积)和Monaco(蒙特卡洛)计划系统，重新计算剂量对术前总肿瘤体积(GTV)、计划肿瘤体积(PTV)和危险器官(OAR)的影响，并与鼻填充物进行比较。结果:确定了24例患者，主要是筛窦(14)或上颌(4)初级。主要组织学为鳞状细胞癌(12/24)。大多数患者(22/24)以治愈为目的进行治疗。使用塌锥卷积计算，95%的处方剂量对高剂量PTV的覆盖率中位数[范围]为95.5% [92.2-98.5%]vs 95.2% [92.1-98.5%];有包装vs无包装，P=1.00)和低剂量PTV (95.8% [90.0-99.4%] vs 95.9% [91.1-99.7%];填充与未填充，P=1.00)不受鼻腔填充的影响。无填塞对脑干、视神经、视交叉和晶状体的最大剂量也没有影响。结论:鼻腔填塞对辅助IMRT或VMAT治疗的鼻、鼻窦癌患者的pvt或关键OARs的剂量没有影响，可以安全省略。

Kilovoltage (kV) radiotherapy, also called superficial radiotherapy (SXT) or orthovoltage radiotherapy (DXT), is a well-known and effective treatment option for non-melanoma skin cancer and some benign skin and musculoskeletal conditions. Given its surface dose delivery, its use in radiation oncology beyond superficial skin cancers is generally limited, but it has also been shown to be extremely useful for specific palliative applications. Here, we describe the characteristics of kilovoltage radiotherapy and report on six cases of locally advanced and/or metastatic breast cancer in which kilovoltage radiotherapy was used as the primary modality or as supportive treatment to linac-based radiotherapy to gain local tumor control and improve the patient’s quality of life.
