Easy Way to Perform Venipuncture

Hariette A.W.

With the new curiculum of the BSRT here in the Philippines, as based on CHED Memo #18, Venipuncture is now included as one of the major subjects, since we need to learn the basics of this procedure for the introduction of Contrast Media (CM)/Radioactive Materials (RAM) to the patients. Although I have already posted a detailed guide of venipuncture, especially for beginners, now, here’s a quick and easy way to guide us on how to perform it: Materials Required for Venipuncture Procedure: Sterile gauze pads (2″ x 2″) 70% isopropyl alcohol or povidone-iodine solution pads Tourniquet needles and holder tube Click Here To Read More

Recommended HVL for Equivalent KVP Values

Hariette A.W.

It has been demonstrated that beam filtration significantly reduces patient skin dose, and filtration above 3.0 mm aluminum can significantly reduce the intensity of the primary beam requiring an increase in the exposure technique to compensate for lost photons. Therefore, filtration greater than 3.0 mm aluminum equivalency is not recommended by the NCRP. Filtration removes mainly those photons of less than 40 keV effectively hardening the beam. The quality of the x-ray beam is therefore improved because it increases the half value layer (HVL) of the beam. NCRP regulations specifying filtration are in HVL units because this is the biomedical Click Here To Read More

Cabinets and Vaults to Protect the Radiographers from Radiation Exposures

Hariette A.W.

A new technology has been designed to protect the radiologic technologists from unnecessary scatter radiation during exposure. These are the exposure vaults and cabinets. This cabinets and vaults allow the radiographers to work safely in the radiation area even when there is a radiation exposure done. These exposure vaults are like large walk-in rooms made of lead and high-density concrete block to provide safety to the radiation workers by protecting them fom unnecessary radiation exposure. On the other hand, exposure cabinets are ususally self-contained cabinets with integrated x-ray imaging equipment which are commonly shielded with lead and steel to absorb Click Here To Read More
