(2) The intensity-modulated or B-scan in which various scans are taken through the pupillary area and any change in acoustic impedance is shown as a dot on the oscilloscope screen, and these join up as the transducer moves across a meridian. The A-scan is useful for the study of the biometric measurements, as well as measurements of intraocular tumour size (e.g. Thus echoes from surfaces deeper within the eye take longer to return to the transducer for conversion into electrical potential and so they appear further along the time base on the oscilloscope display. Two types of ultrasonographic measurements are used: (1) The time-amplitude or A-scan which measures the time or distance from the transducer to the interface and back. This latter method eliminates the risk of indentation of the cornea and underestimation of the anterior chamber depth and axial length. Echoes from the interfaces between the various media of the eye are converted into an electrical potential by a piezoelectrical crystal and can be displayed as deflections or spikes on a cathode-ray oscilloscope.There are two basic techniques used for examination: a contact system (often referred to as applanation) described above in which the probe is in contact with cornea and an immersion system in which the transducer and the cornea are separated by a water bath.
The reflected vibration is called an echo. The ultrasound wave is reflected back when it encounters a change in density (or elasticity) of the medium through which it is passing. The technique is used to make biometric measurements such as the axial length of the eye, the depth of the anterior chamber, the thickness of the lens, the distance between the back of the lens and the retina, the thickness of the cornea and detect ocular pathology.
The silicone probe, which rests on the eye, is separated from the transducer by a water column to segregate the noise from the transducer. This will allow both characters to easily accumulate their ST gauge, allowing Crimson Wizard to use Ancient Curse much more frequently.A technique utilizing high frequency ultrasound waves (greater than 18 000 Hz) emitted by a transducer placed near the eye. It is highly recommended to pair Crimson Wizard with ★4 Popoi -Headed for the Home Village- (Fire/Boomerang) or any other strong Fire-type character in your team. The impact and destruction radius caused by the technique almost fills the entire screen, making it an incredibly handy weapon to wipe out regular foes and even bosses quickly.
Crimson Wizard also has Mystic Torrent which temporarily increases his already impressive damage output to easily burst down bosses, especially those weak to fire.Īlly Character Tier List Special Technique – Ancient CurseĬrimson Wizard’s Special Technique (ST) is Ancient Curse which allows him to summon a massive meteor on the battlefield. He is able to clear waves of enemies using Exploder, a powerful area-of-effect magic skill, from a safe distance.
