Management Of External Radiotherapy Irradiation In Vaginal Cancer Using Intensity Modulated Radiation Therapy (IMRT) Technique At The Cancer Center Radiotherapy Santosa Hospital Bandung Kopo. Vaginal carcinoma constitutes approximately 2% of all malignant neoplasms that occur in the female genital tract. Vaginal carcinoma can arise from various types of cells within the vaginal wall and is often associated with risk factors such as exposure to certain carcinogens (8). Cancer is one of the main causes of death throughout the world. Based on GLOBOCAN data, the International Agency for Research on Cancer (IARC) in 2018, deaths caused by cancer reached around 9.5 million people, with 60% of cancer deaths in Asia. (7) Radiotherapy is a cancer treatment approach that uses light. ionizer to damage tumor cells while maintaining the integrity of surrounding healthy tissue. The main focus is to eliminate as many cancer cells as possible while reducing the negative impact on normal tissue around the tumor area. (20) There are several treatments for patients suffering from vaginal cancer, namely surgery, radiation, brachytherapy, and  external radiation based on the size and stage of the tumor suffered by the patient. (3) Based on the book "Target Volume Dileniation And Filed Setup" (a practical guide for conformal and Intensity-Modulated Radioation Therapy), Arno.J, (2013: 201), all vaginal cancer patients who undergo radiation using the IMRT technique must simulated in a supine position and the patient's legs straight with a thermoplastic immobilization mask and adjusted immobilization of the upper and lower body (16).

The Effect Of Use Of Lung Mask Fixation On The Accuracy Of Targeted Irradiation In Lung Cancer Intensity Modulated Radiation Therapy (Imrt) Technique In The Department Of Radiation Oncology, Jakarta General Hospital. Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. While normal cells in the lungs usually develop and reproduce to form healthy lung tissue, these abnormal cells actually reproduce more quickly and are never able to become normal lung tissue. As a result, lumps of cancer cells are formed, which are often referred to as tumors. (4) Radiotherapy is a form of therapy that has been proven to be useful in treating cancer. The aim of radiotherapy is to provide safe, accurate and efficient radiation doses to treat various types of cancer and also non-malignant disorders (7). Carrying out radiotherapy for lung cancer involves the use of immobilization devices, one of which is a thermoplastic mask. This mask functions to reduce the patient's body movements, including movements caused by breathing (9). Verification is a critical stage in the radiotherapy process. The purpose of this verification is to ensure that there are no significant differences in the exposure carried out (14). Giving the right dose of radiotherapy radiation is very necessary to achieve successful therapeutic treatment. The accuracy of dosing and the accuracy of the patient's position influence the dose distribution that will be received by the patient. This verification is based on the International Atomic Energy Agency (IAEA) Human Health Series No. 31 of 2016 with a displacement value of 0.3cm (15). EPID (Electronic Portal Imaging Device) is an additional device connected to the LINAC (Linear Accelerator) radiotherapy device. EPID functions as a verification tool for radiation dose and geometry which is very important in the radiotherapy process (16). The accuracy of the patient's position during radiation treatment greatly influences the accuracy of the IMRT technique. Before irradiation, verification is carried out using an EPID (Electronic Portal Imaging Device) to ensure the correct target position on the tumor. This helps measure the x, y, and z axis coordinates along the radiation area before the radiation procedure begins.

The problem that must be overcome by all parties is garbage. Society must take an active role to solve this problem. In an effort to safeguard the environment, the Maju Jaya Waste Bank has a role in sorting and processing waste. Organic waste will become fertilizer. Plastic or non-organic waste will be the raw material for the Paving Blok Prima Lestari Bumi Group. Paving Block Prima Lestari Bumi Group will process plastic waste into paving blocks. However, there are several problems faced. The problem faced by Prima Lestari partner Bumi Paving Blok, such as the lack of supply of raw materials for plastic waste, lack of operational equipment, which causes the production of paving blocks cannot maximize. The level of sales still cannot meet the target per month. Current marketing aspects are carried out by word of mouth and take part in exhibitions carried out by the local government or using social media. For Maju Jaya Garbage Bank, the problem is a large amount of operational costs to sort waste based on the type of waste. This is inversely proportional to income from processed products that are less than optimal. Some of the solutions offered to partners are several parts of training for the sale of goods, procurement of operational goods such as production machinery for paving blocks and machines that can sort waste by type to reduce operating costs.

Latar Belakang: Lymph node cancer in the case of Hodkin's Lymphoma is a type of cancer. Lymphoma is a solid tumor of the immune system. Hodgkin lymphoma (HL) accounts for about 10% of all lymphomas. The Intensity Modulated Radiation Therapy (IMRT) technique is one of the cancer treatment techniques in Hodgkin's Lymphoma cases.

Background: Thyroid tumors are abnormal growths of the thyroid gland, which can be benign or malignant tumors such as papillary, follicular, medullary or anaplastic types (Aldino, 2018). CT scan of the neck according to (Lee at al, 2016) The contrast media used consists of 80 ml of non-ionic contrast media followed by 20 ml of saline given through the antecubital vein using a power injector and a 20 gauge intravenous catheter at a speed of 2.5- 3.0 ml/sec. According to (Yang et al., 2016) 80-100 ml of 300 mg/L omnipaque contrast media is injected through the cubital vein at a rate of 2.7-3.0 mL/s. And according to (Deng et al., 2019), 80 ml of iopromide (300 mgl/mL) contrast media is injected intravenously at a rate of 3 ml/sec. The aim of this research is to determine the procedure for a CT scan of the neck with contrast in cases of thyroid tumors in the radiology installation at the NTB Provincial Regional Hospital. Method: The type of research carried out is qualitative research with a case study approach. Data were collected by observation, interviews with one radiologist and three radiographers and documentation. Data collection was carried out from June to July 2023. Data analysis was carried out using an interactive model system. Results: This study shows that the contrast media used in CT scans of the neck uses 50 ml contrast media on the grounds that 50 ml contrast media can confirm the diagnosis because in the case of tumors in the thyroid you only want to see whether there is enhancement of the tumor. And the contrast media injection is carried out manually by a radiology nurse on the grounds that it is sufficient to confirm the diagnosis if it is carried out with proper control so that the examination is simpler and the processing time is faster. Conclusion: There is a difference in the CT scan of the neck between theory and the NTB provincial hospital where in theory Lee et al (2016) explains that 80 ml of contrast media is used and an injector is used at a speed of 2.5-3.0 ml/s while the provincial hospital NTB uses 50 ml contrast media and is injected manually by a radiology nurse on the grounds that this can confirm the diagnosis.
