RADIATION THERAPY-1-LESSON 144

-



Radiation Therapy:  X-rays and radionuclides are used in the medical field for both detecting disease, as well as curing diseases in the form of therapy. Using large doses of radiation materials via therapy is life-threatening event to the calls of the body those are irradiated.
The specialization of radiation oncology has been chiefly ready to lend a hand as a technique for the handling of cancers. The equipments used for radiation oncology are unlike from those used for detection of diseases. The machines used in radiation therapy bring about rays of many times higher intensity.
Orthovoltage machines deliver low-energy radiation, which in modern treatment centers is used in managing cancers for superficial skin cancers. Megavoltage machines produce high-energy radiation. These megavoltage machines are used to heal more profound tissues. This is curative radiotherapy treatment for cancer.
Betatron and linear accelerator are the two types of radiotherapy equipments. They produce a penetratingly clear radiation rays to a certain area of the body at the same time as cautious superimposing of the surface tissue.
Radiation may be applied to a tumor from some distance (external beam radiation) or implanted within the tumor itself called brachytherapy. External beam machines such as linear accelerator, direct a beam of photons toward the tumor. The higher the energy of the photons, the greater the penetration of the beam. Photons can also be produced from a radioactive source such as cobalt-60, both sources of high-energy photons i.e. linear accelerator and cobalt are well suited for the treatment of deep-seated tumors.

Next lesson is the continuation of radiotherapy. Okay.

Abdominopelvic Quadrants and Regions - Lesson 5

-
Abdominopelvic quadrants and regions are divided into 9 regions as per the division of the abdominal and pelvic cavities to explain the regions in which internal organs are found. They are as follows: Hypochondriac, epigastric, lumbar, umbilical, inguinal, and hypogastric. Now we will see about all abdominopelvic quadrants and regions one by one now. 1. Hypochondriac regions (2): The two upper right and left regions below the cartilage (chondr/o) of the ribs that extend over the abdomen. 2. Epigastric regions (2): This is the region above the stomach. 3. Lumbar regions (2): The two right and left regions near the waist part of the body. 4. Umbilical regions (1): The region of the umbilicus or navel portion of the body. 5. Inguinal regions (2): The two lower right and left regions of the body, inguin/o means groin that is the area where the two legs join together with the trunk of the body. This region is also called iliac regions because they are near the ilium part

Parts of Speech - Noun, Pronoun, Verb, and Adverb - A Medical Transcriptionist Must Know.

-
Image
Grammar is very crucial in any language.  A medical transcriptionist must be well-versed in his language skills i.e. writing skills.  This unavoidable skill needs specialized knowledge in English grammar apart from strong listening skills and medical language skills, computer operating skills, and fast typing skills are of having secondary importance to be a successful medical transcription professional. In this post, we will see about basic parts of speech in English, such as, 1.  NOUN. 2.  PRONOUN. 3.  VERB. 4.  ADVERB.  We will see about one by one now. 1.  Noun - A noun is used to denote a name of a person, animal, place, of a inhuman thing in the universe.  For example, 1.  John is a name that denotes a boy.  2.  Dog is a name that specifies an animal. 3.  San Diego is mentioned to denote a place. 4.  Stone is denoted to specify an inhuman thing. Further read about NOUN 2.  Pronoun:  In a language, pronoun is used to specify any type of noun i

Body Cells and Differentiation-Lesson 1

-
Image
Body cells are different types. We often may read about stem cell types. Like in a movie there are many actors to do their different roles to establish a story, in our body there are different kinds of cells to do different roles to keep the body stable and active. The cells in our body are of two types: 1. Somatic cells. Our body contains Muscle cells, Nerve cells, Skin cells, and Fat cells. These kind of cells performing mainly body related functions and so they are called Somatic cells. There are varieties of cells inside the body. Every cell is different or specially created to do their special role inside the body throughout. Fat Cell: For example in body cells a FAT CELL has in it empty and large spaces for fat storage, and a muscle is slender and long and has in it fiber material that help in relaxing and contracting, as well as a skin cell is square in shape and also flat in structure to give protection to our body and a nerve cell which is long in struct
