promotes excellence in the field and sets high educational standards. adopted a code of conduct
The imaging of deep structures of the body by recording echoes of pulses of ultrasonic waves directed into the tissues and reflected by tissue planes where there is a change in density.
an Allied Health professional with special training in the use of ultrasound equipment for diagnostic and therapeutic purposes. One who graphs or draws with sound.
a device that converts electrical signals into ultrasound waves and ultrasound waves back into electrical impulses.
an instrument for measuring the sharpness and range of hearing through the use of controlled amounts of sound.
a vertical plane passing through the standing body from front to back. The mid-sagittal, or median, plane splits the body into equal left and right halves.
a horizontal plane passing through the standing body so that the transverse plane is parallel to the floor.
christian johann doppler
an Austrian scientist who first postulated the effect of motion on the pitch of sounds and named it the Doppler Effect.
discovered piezoelectricity. They established the presence of the piezoelectric effect when they observed that crystals will expand and contract when placed in an alternating electrical field. Their discoveries led to the development of the modern transducer.
The property of certain crystals that causes them to produce voltage when a mechanical pressure such as sound vibrations is applied to them.
first to use ultrasound to detect tissue thickness. researched that cancerous tissue is different from normal tissue. constructed early prototype breat scanner and rectal transducer to scan large bowel.
developed a contact compound scanner along with Tom Brown in 1957. In 1960 they developed a mechanical sector scanner, then later a hand-held scanner which they called the diasonograph. He is credited with contributing to the diagnosis of hydramnios, multiple pregnancies, and hydatidiform. He also introduced the fluid-filled bladder technique. He is well known as the "father of obstetric ultrasound" for the first demonstration of a fetal gestational sac.
- temperature, pulse, respirations, and blood pressure as indicators of the functioning of the body.
measures taken to keep health care workers, patients, and the environment clean to prevent the spread of germs; sterile or free of microorganisms
Separation from others to prevent the spread, by contact or airborne transmission, of highly contagious diseases.
used to protect others from germs in the patient's nose, mouth, throat, and lungs. It is used for diseases that are airborne.
used in diseases involving ingestion of disease-producing microorganisms to protect others from germs in the patient's bowels, bladder, and stomach.
used to protect others from germs in patient's wounds or any other heavily contaminated areas.
reverse protective isolation
protects patients from the germs of others. It is used with persons who have extremely impaired resistance.
an abnormally fast heart rate. Can be caused by heart problems, fever, and overactive thyroid, or drugs.
The relaxation of the heart between contractions. The dilation or enlargement of an opening or a hollow organ or tube.
suggested program to provide safety to both patient and caregiver from blood or certain infections. The CDC and other federal agencies have compiled these recommendations.
greek mathematician, began systematic study of sound and observed the relationship between sound pitch and frequency
archytas of tarentum
greek schloar; defined nature of sound. sound is produced by the motion of one object striking another. fast motion - high pitch. slow motion - low pitch.
greek philosopher; produced theory of sound propagation. sound is carried by the ears by the movement of air
roman philosopher; first to compare sound waves to the waves produced by dropping a pebble into a calm body of water.
leonardo da vinci
originated the idea that sound travels in waves. credited discovery that angle of reflection = angle of incidence.
studied activities of bats. theorized bats were listening to something he could not hear.
explored possibilities that high intensity ultrasound could provide a noninvasive lower risk surgical technique. designed multiple transducer system of focused high intensity beams to produce pinpoint lesion without damaging surrounding tissue.
francis fry and elizabeth kelly
studied use of ultrasound to detect breast cancer. kelly is one of the leading authorities on ultrasonic breast scanning
eye contact, facial expressions, body movements & postures, tone of voice and touch
The state or quality of being adequately or well qualified; ability. A specific range of skill, knowledge, or ability. In sonography requires continuing education in addition to training.
discretion in keeping secret information, patient's right to privacy of all medical information
The totality of socially transmitted behavior patterns, arts, beliefs, institutions, and all other products of human work and thought. These patterns, traits, and products considered as the expression of a particular period, class, community, or population
region surrounding a person which they regard as psychologically theirs. Invasion of personal space often leads to discomfort, anger, or anxiety on the part of the victim. Personal space varies from culture to culture.
automatic type of communication that people use out of habit. Consists of polite friendly exchanges of factual and social information.
stages of behaviors that people experience when a loss occurs. The process often takes a considerable time period and passage through it may not go smoothly or in the "proper" order.
Grieving Process: Stage 5
acceptance: patient is at peace with him/herself, controlled stage where intense feelings are absent.
underdevelopment of tissue or an organ, usually caused by a
decrease in the number of cells.
the death or decay of one or more cells, or a portion of tissue
in which the growth is uncontrolled and progressive;usually results from an interruption of blood supply or injury.
