Gelatin
To make a blue phantom, you need a mixture of hot water and unflavored gelatin powder. One teaspoon of cornstarch is also required. Five ml of unsweetened evaporated milk is also necessary. You can add one drop of food coloring if you wish. Be sure to mix the gelatin mixture well. Once it has reached frothy consistency, could you remove it from the container?
Another advantage of a gelatin phantom is its affordability. It can cost less than a hundred dollars. The best part is that it’s easy to make and requires no special equipment. You can even use commercial jelly or grapes. This material can mimic a variety of pathologies and has many uses in interventional radiology.
A recent study evaluated the durability of different gelatin formulas. A study used a gelatin phantom based on Knox gelatin obtained from Kraft Foods and a standard 10%-by-mass ordinance gelatin solution. The spirits were compressed to a depth of 2 cm, and the durability and desiccation of the gelatin phantoms were determined. The gelatin phantoms were evaluated by clinical researchers with training in ultrasound imaging. They were scored on a 7-point Likert scale.
Compared to agar-based phantoms, gelatin is the most stable in time. However, it needs special storage conditions. Agar-based ghosts are less durable and can easily break down.
Ballistics Gel
Ballistics gel is an innovative new material for simulation phantoms that offers a realistic simulation experience for a low cost. Its transparent appearance is excellent for novice learners but can also be easily tinted to add difficulty for more experienced learners. The ballistic gel’s easy and fast preparation makes it ideal for various skill instruction applications.
Cut the ballistic gel into cubes of about an inch in size and place in a slow cooker or a stovetop. Heat the cubes of ballistic gel until they are about 200 degrees Fahrenheit. Once the cubes are melted, pour them into the pan in layers. After the model has cooled, you can remove it from the pan. Once cooled, inject the fluid into the latex vessels.
Fresh-frozen cadavers
Fresh-frozen cadavers are a valuable tool in the learning of endovascular procedures. They provide a realistic simulation model, minimizing the need for animal experimentation. They can also be used to develop new techniques for endovascular procedures and evaluate the effectiveness of new endovascular devices.
Fresh-frozen cadavers are a popular option for training. This cadaver preserves anatomical detail and allows for accurate ultrasound images of needle-tissue interaction. However, these cadavers have several disadvantages. First, they are stiff, lack tissue elasticity, and decompose rapidly. Moreover, they do not tolerate repeated injections well.
Fresh-frozen cadavers are also a good training tool for laparoscopic surgery. Compared to the VRS, fresh-frozen cadavers allow for better training. High-fidelity VRS is still an essential tool for BLT training, but fresh-frozen cadavers may be the better option.
Fresh-frozen cadavers are also suitable for vascular dissections. They can be infused with a dyed gelatin suspension to mimic vascular anatomy. For this purpose, 238 g of gelatin was added to 3 L of saline and stirred for 30 minutes. The solution was then colored red using alizarin red dye. Using a gravity feed, the dyed gelatin solution was infused into the superficial femoral artery.
The advantage of fresh-frozen cadavers over Thiel cadavers is that they preserve vascular anatomy, allowing more realistic imaging. Participants have rated these cadavers highly. However, the disadvantage of Thiel cadavers is that they lack normal vascular anatomy. This makes it challenging to perform nerve blocks near blood vessels. Blood vessels are often better targets for ultrasound than nerves. However, their landmarks can guide the localization of neural structures.
Thinking Putty
When the moon is blue, it catches the eye of many, making the extra full moon an infrequent and magical event. This putty mimics that phenomenon with its unique characteristics. It is pale yellow during the day, but when it glows in the dark, it turns a vivid sky blue. It’s an ideal stress reliever and lends itself to hand agility exercises.
Aquatic fish
Blue phantoms are excellent community aquarium fish and don’t require a large tank to thrive. This fish prefers caves, rocks, and driftwood as hiding places. They are not sensitive to water chemistry and will adapt to many types of aquarium conditions. The blue phantom’s peaceful temperament and low-maintenance requirements make them an excellent choice for aquariums with many different fish species.
While they do well with other fish species, they may fight if they are of the same species. The lifespan of an individual blue phantom depends on several factors. For example, keeping the species separate may be a good idea if it is the same species as another pleco.
Blue phantoms are riverine fish native to Venezuela’s northern Rio Orinoco drainage. They live in rivers and streams with rocky substrates and feed on algae. Their body color is almost inky black, but they have varying patterns of blue spots throughout their bodies. These spots are also present on their fins.
The Blue phantom pleco, also known as L128 pleco, is a unique species of pleco that can grow to over two feet in length. It is a swift swimmer and should be given enough room in the tank to move freely. The Blue phantom can live up to 8 years in captivity as a medium-sized fish. The blue spirit is a good choice for community aquariums.
Gelatin phantoms
Gelatin phantoms are a simple and inexpensive model to help train medical professionals. They are instrumental in training novice residents. As the practice of medicine continues to change, training personnel will play an important role. Fortunately, the use of gelatin phantoms is not only legal but also free of financial risk.
These phantoms are gelatin and other ingredients commonly used in home kitchens. They can simulate tumors, pulmonary edema, and even an abscess. They are also an excellent tool for pericardiocentesis simulation.
A recent study used gelatin phantoms to assess the durability of these formulas. The researchers used Knox gelatin, obtained from Kraft Foods, and a standard 10%-by-mass ordinance gelatin solution. The spirits were then tested for durability and resistance to desiccation. A total of four ghosts were created, and clinicians with ultrasound training assessed them on a 7-point Likert scale.
The properties of gelatin-based phantoms are similar to those of biological tissues in absorption and refractive index. They are, however, more stable over time. Gelatin phantoms are also more durable as they do not degrade, despite their water content. Agar-based ghosts are not as strict. They require special storage conditions. The phantoms are not always suitable for high-temperature experiments or calibrations of thermal modalities.
There were several improvements between Phase 1 and Phase 2. The gelatin mix was changed to increase the phantom’s resilience, and the addition of an ultrasound machine improved the workflow.
